What are the precautions for surfing the Internet in thunderstorm weather?

Summer is a season of frequent thunderstorms, and computers at home are easily damaged by lightning and communication failures. In order to avoid this situation and protect your property from loss, I suggest you continue reading the following:

Lightning strikes are generally divided into direct lightning and inductive lightning. Lightning rods installed in buildings can only prevent direct lightning, while induction lightning harms indoor household appliances, especially computers, through external lines. Therefore, it is necessary to pay attention to lightning protection in thunderstorm days. The following lightning protection methods are for your reference:

1, pay attention to regularly check the grounding wire used by the computer. Almost all the shells of most computers are connected by this kind of grounding wire, the main purpose is to protect personal safety. In addition, external wires can also eliminate the influence of static electricity on the equipment.

2. Keep a certain distance between the computer and the external walls and columns of the building. Especially in high-rise buildings in cities, there are a lot of steel bars in the columns. Because when the building where you live is attacked by direct lightning or side lightning, strong lightning current will flow into the ground along the external walls and columns of the building. In this process, due to the strong lightning current flowing through the external walls or columns of buildings, electric and magnetic fields will be generated in the surrounding space. If the computer is too close to the external wall or column, it may damage the integrated circuit module in the computer.

3. Try not to surf the Internet in thunderstorm weather, because lightning may come in through the power cord and burn the modem and even the network card and motherboard of the computer.

4. Even if lightning is not directly introduced, generally speaking, the network card, modem and computer power supply are easily damaged in thunderstorm weather. The reason is that the equipment is directly connected to the long line, similar to the radio antenna, which is sensitive to the electromagnetic field induction in the lightning space, and the integrated circuit module is easy to be damaged and destroyed under the instantaneous induction of high voltage (the fault occurs in the next week).

5. When the thunderstorm comes, unplug all kinds of lines connected to the computer (including power cord, network cable, telephone line, etc.). ) as much as possible. Although your home may not be equipped with professional lightning protection facilities, as long as you start from the above small things, you can protect the safety of your computer to the maximum extent and reduce the losses caused by lightning.
