How to lightning-proof household appliances

Close the window before it thunders and rains. Some users think that lightning rods can be installed on TV signal lines to prevent TV from being struck by lightning. However, it is recommended that relevant professionals install lightning rods. After all, if the lightning rod is not installed scientifically enough, the lightning rod will no longer be "lightning protection" but "lightning attracting". Once struck by lightning, hundreds of thousands of volts of lightning will be transmitted to the TV set through the signal line, which is harmful and useless. Therefore, the simplest and most effective lightning protection method for TV is to place the TV as far away from the window as possible and keep a distance of about 10cm from the wall. When it thunders and rains, close the window first, because the window is an important way for lightning to invade, and then quickly unplug the TV power supply and connect the signal wire, which can better protect the TV from lightning damage.

Computer: Unplug not only the plug, but also the network cable. A computer career that has not been damaged by lightning is not a complete career. As we all know, computer is a high-tech electrical appliance with highly integrated electronic components. Once the semiconductor integrated circuit is instantly broken down by lightning and loses its original polarity, the integrated circuit will be damaged. Therefore, in thunderous weather, it is best to turn off the computer and unplug the power supply.

Lightning protection socket However, it is not enough to just unplug the plug. I remember that once the router and network card were burned out by lightning because the network cable was not unplugged in thunderstorm weather. So in addition to unplugging the plug, you have to unplug the crystal head of the network cable. In addition, in view of the damage of lightning to electrical appliances, the electric plug with lightning protection function has been specially introduced in the market.

Air-conditioning: Stop using in thunderstorm weather, just like the cable signal line of TV. In thunderstorm weather, the outdoor unit of air conditioner is also a guy who is easy to "lead thunder". In the aspect of lightning protection of air conditioners, several factors should be considered: firstly, the outdoor unit of air conditioners should be properly grounded when installed, the compressor should be welded with the down lead of the building or the structural column reinforcement used as the down lead, and the windows of general high-rise buildings can also be welded with equalizing ring taps nearby to prevent direct lightning strike; Secondly, shield the indoor air conditioning host to prevent lightning current from invading. Of course, for the sake of safety, I suggest you turn off the air conditioner and cut off the power supply as much as possible in thunderstorm weather.

Washing machine: avoid connecting with water pipes.

Similar to the computer, the circuit board of the washing machine is a modular integrated microelectronic circuit board, and this highly integrated circuit board has poor lightning resistance. Therefore, the circuit board of the washing machine is also vulnerable to lightning. Generally speaking, we all like to connect the washing machine with the water pipe. Therefore, if the washing machine is unfortunately struck by lightning, resulting in short circuit of the circuit board and leakage of the washing machine, it will greatly endanger the life safety of users. Therefore, users should pay attention to check whether the metal pipes on the roof of the building have been connected with the lightning protection belt. It is best to stop using the washing machine when it thunders and rains, unplug the power socket, and it is best not to connect the washing machine with the water pipe when it is not in use.
