Do you need to unplug the appliance when thundering? This is a cliché problem.
What impact does thundering have on electrical appliances? We all know that thunder and lightning have a very strong destructive power, and for household appliances, lightning wave intrusion is the most important threat.
There are three main types of lightning wave intrusion: The first is that the direct lightning strikes a high-voltage lightning wave to be introduced into the room in the form of waves propagating along both sides of the wire; the second is a high-voltage pulse from the induced lightning, which follows the wave form. The conductors propagated into the room; the third is due to the direct lightning hitting the ground near the house or the house. When the ground net enters the ground, it is transmitted into the room in the form of waves and propagates along the wires to other places. .
Through these methods, the powerful current that climbs into your home will probably destroy the electrical appliances in your home. I believe many readers have heard of watching TV on a thunderstorm and then a lightning strike to destroy the TV.
Is there still a need for thunder power?
Although in the past we often heard of thunder and lightning out of electrical appliances, in fact, this concern has been much less, because new buildings have a more reliable grounding, plus everything from transformers to switches to sockets and power supplies. Surge, so the probability of electrical damage by lightning strikes is already very low. Moreover, the high-rise buildings in the city are everywhere. These high-rise lightning rods have brought a lot of hatred. As long as they are not living in wilderness or deep forests, it is very difficult for Lei to invade and destroy your home appliances through wires.
So now there is not much need to pull power to thunder. However, it is said that the protection of the network cable is very weak (previously the telephone line, but now it does not matter), so it is easy to become a shortcut to the induction of intruders. In fact, there is indeed thunder and lightning. Burn out a modem or router case.
If you live in a lightning-prone area and the network cable is directly connected to your computer, your computer does have a chance to be thundered during thunder! However, generally speaking, you must face the situation of being overwhelmed by darkness and exaggeration. Don't worry about it.
Therefore, it is necessary to analyze the situation of the power cable. If your family or nearby family has a history of being struck by lightning and burning electrical appliances, or if you live in an outskirt, it is safe to thunder at the time of lightning, and to unplug the power and telephone lines, network cables, and cable television lines.
Remember to unplug the power cord. Light off the socket switch is not fully functional. If you live in a city and you don’t experience lightning strikes and burn electrical appliances, you can rest assured that you watch TV on the Internet when thundering. Even if an accident occurs, you have to burn a Modem or router. In general, due to the low probability of being thunderbolted, and urban buildings generally have more complete protection measures, there is no need to worry too much about lightning damage to electrical appliances.
Lightning surge sockets and sockets are not necessary to buy?
On this issue, we specifically asked the staff working in related industries, and the explanation was that once a lightning strike is encountered, the lightning protection and power surge protection sockets and plugs have very limited defense capabilities in case of real risk of lightning strikes. The best way is to cut off all the external lines.
Therefore, lightning protection and surge protection are not necessary. If you want your home's electrical appliances to protect you more, you can purchase related products within the budget. If you do not want to spend too much money on sockets and sockets, then you only need to purchase products that are safe to pass, and you don't need to overdo it for surge protection and surge protection.
To sum up, if you are in a building where there is no experience of electrical damage to lightning strikes, or if there are areas where non-lightning strikes are frequent, then you do not need to worry too much. However, if there is a situation in which an electrical home is damaged by lightning or nearby, or if there is no high-rise nearby, then it is best to unplug all external lines when it is thundering, including the power cord and network cable of the appliance. Telephone lines and digital TV lines. Lastly, lightning surge sockets and sockets are just equivalent to one more insurance. Do not rely too much on the defensive performance of these products.
