Thunderstorm, blisskavka that zakhista electric power of self-harm. Storm guard for fencing
Even from the radian hours, the tradition was saved - in a thunderstorm, all the sockets are out. But what about working with a refrigerator, even if the weather is stormy, it can take a little time, and wine will flow in an hour? Or maybe you have a term project and you can't turn off your computer? But how can you not be at home?
Why can't electricity be used in a thunderstorm - why is it possible after all?
There are hundreds of reasons not to imitate the technique. It’s rich who so and rob with hope that the bliskavka is consumed in the LEP once every 20 years, and carried it through once. Ale, now play the lottery, so you can get away with it calmly with electricity. Let's figure out what the varto is afraid of under the hour of a thunderstorm.
The myth about those that electrical engineering is a lightning magnet
Yak Vee has already understood electrical appliances do not attract glare. This myth is even similar to those that it’s impossible to use mobile phones during a thunderstorm, but it’s not true. Such a statement came after the 2006 interview with the British Medical Journal bmj.com an article was published about those who make a mobile phone stronger than a hit of bliss. But in the text there is not a single word about those that mobile phones attract a thunderstorm.
Tsikavo: the article talked about metal telephones. Vipadki were fixed, if after the blow of a glare, the metal case of the phone was fired and the manager of serious opikiv. Ale, the article appeared in 2006, and at the same time smartphone cases are more importantly made of plastic, like Samsung has that warehouse, like the iPhone. Information from the article has already lost relevance.
After the release of the articles, the newspapers began to mass-produce headlines like “Mobile phones and unsafe hours of thunderstorms.” Skrіz it was said that the victims of the stroke spoke by phone to read that they had wine with them. The theme elicited a resonance and began to spread even more. This is how this popular myth was born. But, how can electrical devices really attract lightning discharges?
How to pour electrical appliances into a thunderstorm
Really, vimknena chi is turned on butova electrical equipment does not flow into a thunderstorm. The reason for the specifics of vindication of this natural phenomenon. In the dark, a static charge accumulates with the strength of pivmillion amperes and the voltage of millions of volts. In order to discharge such energy, it is necessary to have a neutral field, to let the stream of supratemporal tightness pass.
Poglinut such energy can only the earth. The natural bar'єr between plus and minus gloomy land - again, like a dielectric by itself. And just like a charge, scho stingy, gaining enough tension, so that to break through this natural insulation - a blissful light appears. The most frequent electric discharge, even with wooden drops, are the paths of the least support, but in the earth it is located near high objects: chimneys, wet trees, blisskavkovі water thinly. The tiny electromagnetic field of a smartphone, no other technology, can in any way be charged with such tightness.
Technique does not attract thunderstorms, but there you may suffer from them. Sob what didn’t happen, you need to protect.
How to protect equipment in thunderstorm weather?
In the case of popular Oman, bliskavkas are not used at the very core of high-voltage lines. The stench is trampled by the wet wood of the stovpi and they pass near the ground. Ale, a discharge of supratemporal tension that passes, creating a stronger electromagnetic field. Through this, the LEP has an impulse of high tension.
What is the unsafe impulse discharge?
The electronic impulse is destroyed by a conductor, enters the home fence and uses it through the socket in the electrical appliance. through ce burn all electronics from microcircuits. Impulse discharge burns the conductor elements (resistors, thyristors, etc.). As a rule, the electronics after that are no longer suitable for repair.
For heating electrical appliances, the over-voltage electrical impulse is not safe Shards of wine last less than a second and in an hour do not heat the metal to unsafe temperatures.
An electric impulse from a storm can come to the house not only by a power line, but also by a telephone or an Internet cable. At such a time, you must use a wired connection to the Internet.
Pozhezha through such a discharge is unlikely to win, but shkodi looked like a chimalo. For a fraction of a second, the overcurrent burns electronic payments. Sob the fire was on fire, it was necessary to pour gasoline on the board. Such a vipadok can be more than once in a thousand. Prote electronic technology is not cheap and will require protection.
How to protect yourself from a lightning impulse?
For zahistu, it is necessary to add a zahistu in the form of impulse overvoltage (UZIP) or, how else to call it, a discharger. In order for the charge to rise again, the wines can pass through the steps of the grounded defense:
- UZIP on high-voltage lines to carry out a stream over 100 kA;
- Class 1 (B) - conduct from 50 kA to 100 kA, installed at enterprises, administrative offices;
- Class 2 (Z) - znimaє vіd 15 kA to 50 kA;
- Class 3 (D) – conduct from 8 kA up to 45 kA.
The apartments often put class D, and in private booths C and D one by one - for greater efficiency. It’s impossible to talk, in the same way, stovp LEP to drink a bliskavka. For example, as if it were not far away, with the great imovirnistyu of class D, one could not protect the net.
Class B is to be placed on the introduction of bagatovka, where to start darts with a peretina of 25 mm2 and more. A larger thin vein is impossible to miss the straining impulse on the floor, and put it in a high-class arrester, there is no sensation.
After-butovy UZIP is stored in a chemical nap_vprovidnikovy warehouse, which passes overhead jets. From one side to the new wire is connected, from the other - the earth. Like a conductor, a pulse of supra-temporal tension flows, a chemical warehouse passes yoga through itself into the ground.
In order to understand that the thunderstorm specialist has spratsyuvav, a lot of pickers to open the warehouse in such a way that change the color when discharging. Tse does not mean that it is a disposable arrester. Deyakі brandy declare about those, їх models are covered by 2-3, or to get more spratsovuvan.
As an inexpensive discharger, it’s better to replace it after the first spratsovuvannya and not to be suddenly confused. Tim more, the variety of budget analogs starts from 350 hryvnia.
Where do you put the zakhist?
put often one surge arrester per electric line is not enough. There is not a single path of a supratemporal impulse discharge at your merging. There is also a computer and a telephone cable, it is also necessary to protect them.
Internet cable
Often, the provider's Internet cable is connected to the power line. І like a raptom bliskavka to hit at the zey stovp, vinikne at once two impulses, like at once to flow at the booths along the electric lines and the mid-core tethered cable.
If you have installed an SPD on the input and output, having taken one of the strum impulses, then the other one will burn all the electronics on its own way. Light up the router and all computers connected to the Internet with a cable, so that the stench was turned off at that moment. Tom, a special lightning arrester is required for the internet cable.
There is no need to install it in rich top-ups, so that the providers themselves protect the power equipment. The skin of the Internet-vouzol on the version is already possessed by the storm protector. Ale from the skin rule, blame it, that check with provider chi varto put you dodatkovy zahist.
Thunderstorms need to be afraid, as if the Internet was carried out with a copper twisted pair, optical cable - strum not to be carried out.
telephone cable
The situation is similar with telephone lines. The stench is independent from the electric mains and passes overhead impulses with a wet cable. If there is no zahistu that will become a discharge, all telephones will burn. For a private booth, the consequences are not so terrible - to burn one or two telephones. Ale, for example, in the office, use all telephone devices and faxes. And tse zbitkiv for a thousand hryvnia. It is cheaper to put a discharger of a vartystu kіlka hundreds.
At rich apartment booths, the operator can protect the weather from thunderstorms, but in Ukrainian realities, you don’t have to. For example, the lines of Ukrtelecom have a whole lottery, it costs a lot at one time. It is not rare to fall, if through the presence of a lightning protection operator, the on-button technique burned out.
Antenna cable
So the name "Polish antennas" step by step enter the past. Tim is no less, they do it in Ukrainian villages. Signal receivers are placed on 10-meter poles, mostly metal ones, and a coaxial cable is connected to them at the wake.
Such antennas are the best meta for sparkles. After the consumption of the strum impulse flows into the booths and “drives in” the TV. Yak and other equipment, after that won't be repaired anymore. Sob not to bathe a new “screen” after a skin storm, better put lightning arrester for antenna cable.
How to protect me with an electric generator?
Let's say that you have a generator to stand for interruptions in electricity supply or for some other reason. If the light disappears, the backup light is automatically activated through the ATS system. Where should you put a surge arrester?
Yakshcho the generator is small at 3-5 kW and stand by the host, for example, here at the barn, you can simply install a lightning arrester on the main line in front of the AVR. Imovirnist, what to use the sparkle at the reserve jerelo and create an impulse - meager, rather hit it at the barn and escort me. So protect the reserve line, at times - there is no sense.
Another situation, like a generator installations on the streets. As if there is no thunderbolt, bliskavka can be spent until the new, chim, imovirno, vivede out of tune. And yet, not all the beats, even though a supratemporal strum flows through the backup cable, and the AVR system is out of tune.
As soon as the blow of the merezha was alive from the backup dzherel, then the lightning discharge was consumed before it and the electronics were plugged in to the outlet.
Install one lightning arrester after AVR not properly, to that її "vb'є" category from the mіska ї merezhі. If you put a lightning arrester in front of the ATS on the main line, then all the electronics will be in harmony through the backup line. Therefore, in this situation, the most adequate option put two lightning arresters in front of the ATS- for the reserve that mіsku merezh.
How to protect the houses from a thunderstorm?
The hit of glimmers at the booth is accompanied later. The rest of the crowd became fateful on 22 September 2017, if the blow fell on the wake of the appellate court of the Kharkiv region. The tanning started from the dahu, then we fired the fire of the other and the first on top. Zagalna area later became 1500 sq.m. And it's far from the only such kind of fluctuation. Through a thunderstorm, fires are often caught in private households.
Imovirnіst vluchennya lie down due to rich factors: heights of roztashuvannya, accommodation near the current budіvel too. Like a budinok to stand on a hillock, ymovirnist thing, lower yakbi vin standing here at the bottom. So, as if I entrusted the roztashovanі vishchi budіvlі, imovіrno, scho bliskavka to spend in them.
And yet, to wake up to stand at the lowlands, the ability to fall is all the same abandoned. Tse mozhe buti viklikano zbіgo furnishing. For example, if the boards were clear, a thundercloud formed itself over your booth. Hit fit on dah chi near the temple tree. Sob it didn’t happen later, put thunderstorm.
The price of the house was grounded, it was installed at the most important point of life. Through it, electricity is introduced into the ground, where a metal cube is buried - such a design is more convenient to carry out overhead jets. Grounding of lightning may be independent and n_yak don't stick from grounded lines. It is best to spread them to the maximum possible distance.
As soon as the thunderbolt is grounded and the electrical circuits are closed, then the impulse discharge is to be drained to the booth through the sockets. It is all the same for a thunderstorm, why flows are phases, neutrals or groundings.
When planning the thunderbolt to bring in the outer wires, the darts were given to the contour of the grounding, otherwise the impact of the glare provoked an impulse from the adjacent conductors.
Koristuytes electricity in whatever weather
If you put modular lightning arresters at the shield, your equipment will be safe. So you can use the Internet on your computer to navigate thunderstorm weather and not be afraid that all electrical equipment will burn out. The minimum set for a private house is about 1000 UAH. (Maybe more expensive, fallow from the picker). Before entering:
- lightning arresters class C and D;
- lightning arresters for internet cable;
- lightning arrester for telephone line.
This set stitch for 10-15 years, and maybe more, so that your budinok is not rotting in the epicenter of the formation of thunderstorms. What is enough, so that you don’t smack into the skin merekhtinnya in rainy weather and don’t blow, vismikuyuchi all the sockets when the sound of thunder.
We looked at how to protect the houses from the blow of the glare for the help of the thunderbolt, but don’t come in and get separated. About those who still threaten us and how to protect us from these threats, peacefully in this article.
As it was said on the cob, it is not enough to organize a foreign outrage. We know that there is less risk of a bezporednya bliskavka to the booth of those other objects, roztasovannyh on the garden plots. It's a pity that a thunderstorm can pour into the objects, as if they could wind up beyond the borders of the plot. Ale, the result of such an injection becomes serious anxiety and home. In real minds, this kind of noise is more frequent, lower glare is consumed without a middle to the booth.
Internal protection against impulse overvoltage
A channel, which can be a troublesome influx, is the most important electrical and communication infrastructure. So, like a blisskavka drank, for example, in an electric string, wind for a kilometer in the direction of a zamіsky boudinka, Skoda can be sutteva. In the output from the fret of the electronic appliances and the electrical control until the right light. Such a surge is usually called an impulse overvoltage. It should be noted that, if there is a threat, such an overvoltage may be caused by other reasons, for example, an accident at a substation.
There are two reasons for the overvoltage caused by a thunderstorm. Persha, not in the middle of the glare in the middle, mostly electric. Friend, I entrusted the sighting of the sparkle from the mesh. On the right, in the fact that with such an impact, the electric field is blamed, and we take away the induction of an electric stream, which induces an overvoltage. Bliskavka can hit a nearby booth, or maybe beyond the borders of a garden plot. Zvіdsi vysnovok, scho it is impossible to protect the zvnіshnі merezhi from such a place, but it is necessary to protect the treasury without a middle in the booth.
Next, make two important points. First, so that such a system would work, let's rethink, the electric measures themselves could be vykonan with a high rank, zokrema, maybe a full system of building potentials could be implemented. There is no other important moment of universal protection against impulse overvoltage. Therefore, the zonal principle is established, and all attachments to the defense are subdivided into a class of that category. Class A is not of interest to ordinary coristuvachs, it is also recognized for installation at substations. For the zakhist zamіskogo vikoristovuyu vikorivuyu voladnannya class vіd "B" to "D".
Zakhist booth
At the introduction at the booths, ring out the first rive of the defense. For which vicorists have a class “B”, it is necessary to enclose an overvoltage up to a value of 2.5 kV. Call for such purposes, the dischargers of various types are victorious. The vlashtovani stink is simple, schematically there are two contacts, between which the required gap is installed. In savvy minds, such a gap works like a dielectric. When a critical value is reached, breakdowns occur, an arc discharge is established between the contacts and the overvoltage is extinguished on the ground.
Surge arrester for installation at the input
Such dischargers are installed at the very entrance to the booth. It’s worth fighting in order to get lost in the flow to the zahisniy conductor that place of equalization of potentials. Dischargers are used to discharge and gas supply. The parameters of the critical dischargers to lie down in the form of ovnіshnіkh inflows, for example, such as the water content of the reservoir. The return of the water level is lower, but the return of the storm is rarer. Therefore, such a discharger can be protected from accidents at the transformer substation. In this case, the parameters of the overvoltage are vіdomі, scho allows you to choose and necessery attachments. Influence, if the storms are cleared up again and again, the water content will increase again, and also, the level of work will decrease. In the event of such an obedience, the discharger will leave the minds of the winter without care for the nadіyny zakhist and the influx.
The gas-filled surge arrester has insulated contacts with dovkil injections, and the chamber is filled with inert gas under a low pressure. Such attachments may have stable parameters, even if it costs more.
Zakhist line
For example, for a 2.5 kV voltage exchange booth, it can be true, but for other booth lines, it’s over the top. Therefore, it is necessary to attack the border, which will protect the border lines. It’s a pity, I think, that for the zahist to finish simple automatic machines. Tse unsafe pardon. All on the right in the fact that the automatics can be deceitfully recognized - the stinks protect against random situations on the line, for example, a short chime. And the stench of the stench cannot defend the axis of the zovnіshnіkh vplivіv.
Varistors are used for line protection, which are attached to class "C", which protect against impulse overvoltage up to 1.5 kV. A varistor, or a conductor resistor, is most commonly produced in a ceramic viconan. In normal mode, the stench can be opir single GOM, so it is practically not possible to strum on them. When the critical value is reached, the voltage of the opir sharply drops to tens of ohms, with a further increase in the voltage of the opir, it only changes, so the discharge is extinguished to the ground. For Budin's wires (voltage 220/380 50 Hz), it is critical to set the voltage to 470-560 V. Varistors are installed in separate shields on the skin line, so it is necessary to protect them.
Zahist of a specific outbuilding
Remaining rubіzh zahist - zahist of a specific butt fitting. For which vicory is added to the class "D". This is especially true for electronic possession which is sensitive to stribkіv voltage. Good know to us the addition of uninterrupted living space for computers, the installation of filters can be the mother of the necessary protection of the necessary level.
Sound the skin attachments to such strips do not protect - for such butt fittings, such strips do not set shkodi, the variety of others is richer lower, lower organization of such a zahist. For example, it's easier to replace the heating lamp, to protect it from normal voltage cuts. In that case, if a zahist is needed, use an accessory, as if it is possible to navitit an okrem socket. Most of all, we already know the arrester, the truth, the lower critical level of the impulse overvoltage. Can be vikoristan and varistor, also special.
It is important to remember that without organizing the defense of the upper equals, and the tse zachist of the booth of that line, I will still not varto to spodіvatisya on the nadіyny zahist of a particular annex.
Street electric fences
With electric meters, we practically roz_bralis. Having lost more than the rest of the fall. Describes more ways to recognize for the protection of internal fencing in the form of overvoltage, which is generated at the outer fencing. Ale overvoltage can be blamed in the inner yard. So it is necessary, for example, if it is necessary to connect to the electric fence of the outbuilding, which is located on the street. For example, in such a way, the street can be illuminated, or the system will protect you from greenery.
In such situations, it is necessary to organize the installation of electric lines for the inter-house as a line. And as a supplementary attachment, a discharger is installed, similar to the one that is installed at the entrance to the booths.
Zakhist of low-current merezhe
At the current booth of the Crimean electric, install and low-voltage lines. Use the middle of the booth to protect the stench in the face of a storm. And the axis of that fluctuation, as if such strings are taken out of the middle of the booth, the defense is necessary. An obvious butt is a television antenna. Directly received bliskavki tsіlkom imovіrno. Other low-current lines can be led out of the inter-house. For example, for z'ednannya with a home computer system two okremі budіvlі. And it is possible that such a treadmill will be laid for cultivating by automatic watering, or for organizing video warnings. If you lay a cable under the ground, then there will be no direct flashing. Prote, as if guessing about an inductive shock, became aware of what to protect against an impulse overvoltage.
Attach low-voltage wires to DIN rail
For the protection of low-current wires, the dischargers, and varistors, of course, with different parameters can be installed. Ale possessing, like a vicorist such a measure, more sensitive to overvoltage, more often than not, a vicorist combines an attachment, like a gas discharger and a varistor at once.
Attachment to the protection of low-voltage wires of a free installation
Place zakhisn_ outbuildings in low-voltage shields, on din rails. Obviously, SCS (structured cable system) was organized at the booth. If not, then vikoristovuyut pristroї vіlnoї installations, so small boxes, intended for fastening on the wall. It’s good that the outbuildings can be re-insured for a sprat of canals, ring out, no more than a few.
Now the reader knows everything about the defense against the threat of the zamіsky booth. I have lost less realizuvati tsi knowledge of life.
Vadim Zhigulevskiy, rmnt.ru
Increased thunderstorm activity in the summer season zmushuy to get used to entering the runoff from the ruinous surge of the strongest discharges of the bliskavka. You can protect yourself from the strained discharges of natural electricity for the help of modern electronic devices, such as voltage stabilizers and dischargers. Іsnuyu variant zahistu in the face of threats of various possessions, which is traditionally victorious in the field (including fencing routers and other elements of communication).
Zakhist electrical power
The direct hit of the bliskavka in the booths threatens not only with the threat of the direct shock of the future, but also to lead to the establishment of strong electromagnetic watering and directing streams. The number of physical effects is responsible for significant surges of voltage, building damages, if it is in the hour of a thunderstorm, it is connected to the electric power supply. Particularly often suffer from a threat routers, commutators (lights) and computers. With an uninterrupted injection of discharges onto the electrical wiring, darts can melt, causing a short hum, which often leads to burning.
With the help of the method of zabіgannya, it is accepted to beat the future of the storm, to win special technіchnі zasobi. The stench is between the voltage and it ensures the reduction of the effect of electromagnetic interference. Before such zabіv zakhist in the face of a threat can be seen:
- special dischargers;
- voltage stabilizers, which are in measure;
- intermediate overvoltage OVR and others similar to them are attached.
To gain respect for the functions of a pulsed arrester and for separating the confusion in a number of modern electrical appliances, so that they were placed on the edge, see purely mentally.
Types of stabilizers
Stabilizers, as a rule, zastosovayutsya for zahistu merezh in the sharp streams of the voltage of life, calling out interruptions in the electricity supply, or a filthy one. However, in singing situations, you need to make sure that the buildings are safe for the protection of electricity and in the light of the bliss, as if there was a thunderstorm.
There are three types of voltage stabilizers:
- the simplest regulators type "LATR";
- relay type systems;
- stabilizers.
For the protection of electrical networks in the event of a thunderstorm, it is necessary to use only lightning strikes of another and third type of stabilizers, which will ensure the necessary lightning response to a lightning discharge.
Additional information. For protection from natural electricity, it is optimal to use industrial stabilizers with a lightning protection device, equipped with a special discharge unit.
At the best fit on the simistors, which is based on the principle of key switching of power lances. The only shortfall of such stabilizers is high varity.
Razryadniki (intermediary overvoltage)
Zastosuvannya obzhuvachіv as an element of zakhistu elektroobladnannya in denmark wide widening, which is explained by their apparently low price and efficiency. There are three modifications of these outbuildings, the skin of which is given its own class, similar to the characteristics of the automatic fencing (classes B, C and D are appropriate).
Attach the first class to save the practice of forceful lancers in the way of introducing unsafe aims at the sinful earth. Attachment is built in a modular design with a hermetically sealed arrester that reacts to overjet.
Such a block is installed at a separate shield in the cable of introduction (to the electric heater) and it securely protects from transferring unsafe directives to the PEN conductor. Appliances of this class are installed on industrial objects, at state institutions and mortgages, as well as at buddies, which enter the warehouse of great living complexes.
Dischargers of a different type (class Z), for their functionality, we will look more similarly, and then we can’t see that stinks can be spratsovuvaty and in the form of splendid fluctuations, which are accompanied by bursts of strum in the electric circuit.
І, nareshti, attach to class D are assigned to defend against the threat of okremikh spozhivachіv, connected to the circuit of the electric line. The stench is installed without intermediary at the power outlets of the coristuvach, protecting the electrical wiring from impulse overvoltages.
For the help of such built-in outbuildings, one can protect the computer from threats, as well as ensure the smooth operation of the router, which is in the apartment.
Add a telecoms protection
Irrespective of those who coaxial cable lines wind up with a high resistance to the influx of strong power fields - in singing minds (mostly - at the hour of a thunderstorm) the stench is to be knocked out in different ways. Similarly, on the right and with the so-called "twisted pairs", which also require protection from strong electromagnetic guidance and overvoltage.
For the adoption of all the listing of threats to the industry, the expansion of the attachment under the name "GZ-RS485-T", which protects the double-wire twisted pair, both in the direction, and in the secondary electrostatics. Efficiency of the possession of this class is ensured by shunting the transfer to the grounding bus or automatic closing of the channel.
It is also necessary to push the power supply to the safety of the satellite link. When organizing the operation of such channels with the professional name of satellites (SATELLITE LINE), the protection against overvoltage is also ensured for the assistance of a special facility.
A thunderstorm discharge is even more unsafe, shards of this magnitude can reach as many as hundreds of thousands of volts. In the event of a skin storm, equipment goes out of tune, power lines break down, and people suffer as well. Where it is impossible to hit a blisskavka of significance, it’s good for him to pardon, that this is the manifestation of your budinok.
Bliskavka may not once spend in that chi іnsha dіlyanka elektromérezh and, in case of insecurity, the storm can be underestimated. Even though a blissful woman for a few years of the year didn’t squander in that other row of electric power, it doesn’t mean that such a possibility is turned off.
Blaming in the butovy electric storm surge for the current of the deadly surge, I brought the pobutovy electric appliances, which were switched on at that time at the merzh, and also the insecurity of suffering the bagmen's booth, to the exit from the fret. Also, it is necessary to take care of the protection of home electrical wiring in the event of lightning surges, in order to avoid possible negative consequences.
Nasampered, next, it is important that the protection against overvoltage is due to the safety of the supply organization installed on the power lines of the power supply lines. But, as often used in practice, most of the repeated power lines are rebuying at an unsatisfactory station, and they don’t have to suffer. In such a time, the power supply to the home electrical wiring in the event of possible overvoltages is the problem of the homeowners themselves.
Modular intermediate switch overvoltage
For the protection of electric power lines at rozpodіlchih substations, as well as without intermediary on repeated lines of power lines, non-linear intermediate overvoltages are installed, so called HNN.
The main structural element of these outbuildings is a varistor, an element with non-linear characteristics. The non-linearity of the characteristics influences the change of the varistor support in the field depending on the magnitude of the voltage, which can be increased to a new one.
In the normal mode of work and electrical connections, if the voltage is between the nominal values, the voltage between the switches can be more opir and carry out the strum. At the time of the fault of the overvoltage impulse, which is the fault when a spark hits the electric line, the HLV varistor opir is sharply reduced to the minimum value and the non-significance of the impulse goes to, until the transition of the overvoltage occurs.
In this rank, HNN is between the voltage cuts to a safe level, and by the same token, it protects the possession of that calmness in the form of shocks and other negative effects of overvoltage.
For protection against overvoltage in home electrical wiring, compact modular intermediate overvoltages are used. Such a zahisny attachment is installed at the home of a separate shield and does not take a lot of time.
Modular SNP can be the very principle of work, like intermediaries, like zastosovuyutsya in electrical networks. Vіdpovіdno vіn pratsyuvatime less for the obviousness of the robotic grounding of the electrical wiring. In the other case, the installation of a modular HLV will be indispensable;
So for the implementation of the protection of home electrical wiring in the form of lightning overvoltages for the additional modular intermediary, the overvoltage of the obov'yazykovoy umovoy may be transferred to the configuration of the electrical line or an individual grounding circuit.
Should there be a voltage relay, as well as attachments that can operate a different function (stabilizer, uninterrupted life and other), next to ensure that these attachments can work in the tasks between the working voltage, their voltage is not dependent on the voltage.
Therefore, at the time of hitting a flash of lightning, a lightning impulse will damage the voltage relay and other attachments, which may have a different function, will not only go out of tune, or else it will also go wrong if other electrical appliances are included in the measure, but the unsafe impulse will help the electrical wiring to be switched on.
Therefore, the voltage relay cannot perform the protection function against lightning impulses. But all the same, this zahisny attachment is guilty of buti insertions into.
The voltage relay switches on the electrical wiring at different voltage outputs beyond the allowable ranges, so that the overworld decrease or the increase in the voltage of the buttov electric line can be brought to the exit from the fret of the buttovy electric devices.
Filters
Larger mesh filters can be used to build a varistor, so that given attachments will protect the increase in electrical appliances in the form of voltage strips. A lot of people are bought and taken care of, that it is turned on before the new equipment will be protected from possible voltage drops. But for all that, the fact that the varistor of the mesh filter, as in the intermediary voltage, intervening the unsafe overvoltage impulse is no longer safe for the obviousness of the robotic grounding of the electrical wiring.
At the merezhnoy filter, the varistor is a grounding conductor or a zero conductor of the electrical wiring from the grounding conductor and, at times, due to overvoltage, a non-safe impulse goes to the grounding circuit of the grounding conductor, thereby protecting the electrical equipment from the fault. Therefore, the inclusion of a mesh filter in the mesh, which cannot have a working ground, will start a new function - electric appliances will not be a mother, and at the same time the lightning impulse will appear out of tune.
Other paths of lightning impulses
Defending home electrical wiring in the event of lightning strikes does not allow further protection of electrical appliances in the event of a glare. Don’t forget that the sparkle can hit not only the wires of the electric wires, but also the cable lines of another recognition, like laying in a critical way. In this case, there is a wire cable for the Internet, a TV cable and a telephone cable. Also, the bliskavka can be spent until the position of the antenna is installed.
When a glare gets into the cable or the antenna, the lightning discharge is used up to the annex, which is connected to them. So it is possible to grow visnovoks, so that the presence of a zahistu along the butt line in the form of thunderstorm impulses does not include the hit of unsafe impulses in another way.
When a storm is approaching, a lot of people are connected to a television, a computer, or other equipment, as well as an external antenna, or it is connected to external cable lines. After a thunderstorm, after raising the equipment in the measure, it appears that it went out of whack through a lightning impulse hit through the outside cable or antenna.
How do you come in and learn about zakhistu in your mood? To turn off the possible lightning impulse through the cable, it is necessary to turn it off in the annex. For example, plug in a wired cable from a computer or a router, or else to go for a TV - plug in a cable or a cable from a cable TV box.
There is also a specialization of lightning protection extensions for the protection of trussed cables and extensions in the form of lightning discharges. Ale tsі pristroї dosit expensive and vіdpovіdno in butі not vikoristovuyutsya. Moreover, the stench may appear to be ineffective and not secure at the time of consumption.
For example, it should be noted that getting into the category of flashes in the buttovі electrical appliances, electrical wiring is not safe for people, as if they are in direct proximity to these electrical appliances, electrical wiring elements. If you have a pobutovy electrical appliance, a little bit of bliskavka, you can repair it or get a new one, then for a person it can end badly.
It also does not turn off the ignition of equipment or electrical wiring due to the lightning impulse. Also, it is not possible to protect home electrical wiring from lightning overvoltage, and also to connect the wired cables and external antennas, if possible, when a thunderstorm is approaching.
