Will the use of the computer during lightning affect the computer?

Generally, there are two types of lightning entering the room: from the power line and from the signal line. Power Intrusion On modern buildings, we can see lightning protection devices, when the building is directly struck by lightning, a strong current is directed into the ground along the grounding lead, preventing lightning damage to the building.

We also need to take some necessary lightning protection measures indoors. Technically: we need to install power lightning protection devices on computers, household appliances, communication equipment, etc.

But in fact, because high-rise buildings have relatively complete lightning protection measures, users in the building generally do not need to consider lightning protection from the perspective of power supply. Signal line intrusion is mainly caused by induced lightning surges. Induced lightning generally comes from lightning strikes and inter-cloud discharges, among which the induced surge voltage generated by lightning strikes is larger, and electronic information equipment within a range of 500 meters may be damaged by it.

According to the theory and practical experience of lightning electromagnetic pulse, it is proved that the main reason for the damage of electronic computers and other information equipment is caused by lightning induced surge voltage, which can introduce induced surge voltage waves into the equipment through various signal leads and destroy its chips and interfaces.

So how do you prevent lightning strikes? Before the rainy season comes every year, be sure to check whether the grounding resistance is qualified. For all kinds of experimental instruments and equipment, lightning arresters must be installed according to the regulations, and the computer should not only cut off the power supply for the computer that is not often used in thunderstorms, but also unplug the network cable at the same time, so as to effectively prevent lightning strikes.

This depends on whether there is a three-way power supply in your home, if it is three-way grounding, it has no impact on the computer, and there will be no point

There is danger. 1. According to the relevant IEC specifications, the lightning rod belongs to the lightning protection device of the outer high warning department, and the purpose is to protect the building body from lightning damage. However, it is not friendly and can prevent lightning currents from entering the room along the line.

2. To prevent the lightning current entering the line, it is necessary to take internal lightning protection measures, such as shielding, grounding, equipotential and lightning arrester (SPD). Generally, there are no internal lightning protection measures in residential buildings. In other words, there is a possibility that a computer used during a thunderstorm will be struck by lightning.

Voltage fluctuations in summer and daily thunder and lightning have a considerable impact on computers. Because at this time, instantaneous power surges and voltage spikes may occur at any time will directly test your power supply and the host, if your power supply has a protection function, the loss is small, otherwise, you just wait to be depressed. You might say:

I've never had a problem with this. However, once something goes wrong, it will be too late for you to regret it, because natural damage (force majeure damage) is not covered by the warranty. Just as I always recommend everyone to buy a good power supply, a good outlet with surge protection is also indispensable.

Precautions for computer use:

Turn on and off the computer correctly to turn on the power of the monitor first and then turn on the power of the host, and turn it off is the opposite; Never force it to shut down.

Place the computer with care, away from heat, humidity, dust, and direct sunlight.

Pay attention to lightning protection in summerDon't use the computer when it is thundering and raining, and it is best to unplug the power cord.

Avoid the influence of magnetic fields on the computer, do not place too close to the TV, speakers, power amplifiers and ** machines, at least about two meters apart.

To prevent anti-skewering, the computer is equipped with a special anti-static power strip.

Avoid humid environments and run computers that have not been used for a long time during the rainy season; When the weather is dry, increase the air humidity in the room appropriately.

The computer connection power is unplugged, and the network cable is unplugged, which basically has no effect.

Easy to short circuit. Try not to turn on the computer or TV.
