In rainy and thunderous weather, which is easy to damage, broadband box or wireless network box?

When it thunders and rains, lightning has both electrostatic force damage and high voltage damage. Both wireless and wired boxes will be damaged by instantaneous high voltage electricity. If the lightning is really heavy, it is recommended to turn off the electrical appliances.

Due to the strong movement of the atmosphere, high voltage can be instantly discharged through the power line or antenna (mainly long line) of the electrical equipment, which leads to internal breakdown (high voltage damage) or melting (power supply damage) of the electronic components in the electrical equipment, and finally causes permanent damage to the electrical equipment. Moreover, the strong magnetic field generated by this high-voltage discharge sometimes generates high voltage in the transformers of some electrical appliances, burning electronic components. Good electrical appliance manufacturers will take corresponding lightning protection measures when designing circuits, printed circuit boards and high-rise buildings.

Lightning rods must be installed in high-rise buildings, and electrical appliances are not allowed to be used when it thunders. TV: Watching TV when it thunders, the image is unstable and the interference is great, which always makes people afraid. Is this possible? In fact, as long as you don't connect the outdoor antenna and use the TV indoors, there is generally no need to panic, because although the lightning is fierce, before entering the room, the thunderstorm cloud has already discharged with the earth. In the process of short-time discharge, most of its huge energy is converted into heat, light and other energy, so it will not cause harm. Usually, when it thunders, I watch TV in my room. Most of the interference on the screen and in the sound is the radiation energy of lightning, not the energy of induction or discharge. This radiant energy generally won't damage the TV set. However, it must be emphasized that it is very dangerous to use outdoor antennas or watch TV when it thunders. If you watch it, you must take lightning protection measures. Electric light: when it thunders, the voltage becomes very large instantly, which will cause the electric light to go out and cause a fire. However, there is usually no need to turn off the lights. Because the voltage is getting bigger, the work of the substation is suspended, that is to say, there is a power outage, so the lights at home will automatically turn off even if they are not turned off, which is very safe. Computer: Strong lightning voltage will make the semiconductor integrated circuit instantly break down and lose its original polarity, so the integrated circuit will be damaged. A computer is composed of a large number of integrated circuits. When the integrated circuit is broken, the computer is broken. In addition, the voltage of lightning is very high. Instantaneous high-voltage discharge will decompose and burn nitrogen in the air, release a lot of heat and burn the computer. Moreover, the type of lightning belongs to static electricity, and everyone who knows the circuit knows that static electricity is the first killer of integrated circuits. Lightning has the opportunity to generate instantaneous high voltage on wires. At this time, high voltage may break through electrical components, leading to serious explosion and even slight burn of the safety tube. Therefore, if it is in an area with severe thunder, sometimes even the lights have to be turned off, because it may suddenly explode and hurt people nearby. Of course, if the thunderstorm cloud is high, it has no effect. Generally, the thunder that sounds scary is low clouds, so be sure to turn it off at this time!

Lightning does not affect wireless internet access, but it does not have no effect on computers and networks. In fact, lightning mainly "attacks" computers through power and signal lines. In terms of power supply, it is natural to pay attention to it, but now the lightning protection measures of general buildings are good. Pay attention to the use of some good quality and safe power outlets, and don't worry too much.

Voltage fluctuation in summer and daily lightning have great influence on computers. Because at this time, the instantaneous surge and peak voltage that may occur at any time will directly test your power supply and host. If your power supply has protection function, it is also essential to buy a high-quality socket with surge protection function.

Please pay attention to the following points when using the computer:

Turn on the monitor power correctly first, then turn on the host power, and vice versa when turning off the computer; Never shut it down by force;

Second, place the computer correctly and carefully, away from high temperature, humidity and dust, and avoid direct sunlight;

Third, pay attention to lightning protection in summer. Don't use the computer when it thunders and rains. Better unplug the power cord. The telephone on the network cable or ADSL should also be unplugged;

Fourth, avoid the influence of magnetic field on the computer, and don't put it too close to TV, speakers, amplifiers and telephones, at least two meters apart;

Fifth, prevent crosstalk and equip computers with special anti-static wiring boards;

Finally, avoid humid environment and turn on computers that are useless for a while in rainy season; When the weather is dry, appropriately increase the indoor air humidity.

As long as we pay attention to the above measures, the impact on the Internet will be reduced when thunder and lightning strike.
