In thunder and rain, one of the threats to users is power supply lines, and the second is ADSL broadband lines. Lightning strikes on the one hand will cause induced currents, which will generate powerful electrical impulses and surges in the power supply, which will directly lead to damage to the routing equipment and ADSL. In addition, a strong inductive current may also be generated in the network cable, even directly hitting a lightning strike, which directly leads to damage of the router LAN interface or even the router. (Before this year's first thunder, the author has experienced two ADSL, a router, a switch, and a computer power supply that has failed due to lightning.)
Lightning protection measures
Currently, the network equipment with excellent performance on the market has its own lightning protection function. On the power supply line, there are circuit designs for absorbing high-voltage surges. Although the product has the function of lightning protection, the induced voltage generated by lightning is several thousand volts or tens of thousands of volts or even higher. No matter which brand of router, the lightning protection function provided by the router itself may only solve part of the lightning. In order to further reduce the damage caused by lightning, the corresponding hazard protection equipment must be provided.
As mentioned above, one of the threats to the routers during thunder and rain days is the power supply line, and the second is the ADSL broadband line. Based on these two points, we have taken some effective lightning protection measures.
Saving money and effective lightning protection methods
For ordinary ADSL broadband users, making professional lightning protection measures is not realistic. After all, the user’s knowledge of lightning protection measures is not professional. The most cost-effective and effective lightning protection method is manual lightning protection.
Thunder and rainy days, especially during weekends when thunderstorms occur, users do not have problems in their homes. They often turn on their computers and browse the Internet. They do not know that this practice is extremely insecure. Whenever it comes to thunder and rain, ADSL broadband users are better off dialing ADSL broadband modem power and ADSL broadband signal lines. At the same time, the twisted pair cable connecting the ADSL broadband modem to the computer should also be dialed.
In addition, users should not make phone calls during thunder and rain, let alone call mobile phones. Many users think that as long as the network cable connected with the ADSL broadband modem will not be hit by a lightning strike, but who can guarantee 220V civil electricity with good lightning protection measures? For this reason, even if it is raining and raining, you will not be connected to the Internet nor will you open computers and other household appliances.
Business users must turn off the plug power of the computer after work, so as to avoid the damage caused by the voltage formed by the lightning strike. For example, the strong lightning strikes in the news report not only caused the strike of 7 kV grid lines in the city, but also caused a computer power supply to go bad, and the failure of several computers' network cards.
v In summary, in the days of thunder and rain, the most cost-effective and most effective lightning protection measure is to strengthen prevention, cut off the spread of lightning, and ensure the safety of ADSL broadband users to the maximum. For some qualified users, professional lightning protection measures can be deployed to prevent lightning damage. General network products do not belong to products that are not covered by the warranty period due to natural disasters or irresistible external forces caused by thunder and lightning or other external forces. Therefore, users must take special precautions and make lightning protection measures to prevent them from being harmed by lightning. Paying. When many users suffer a lightning strike, they are often broken by routers, switches, and ADSL cats. For natural disasters, they must be prepared for prevention, spend a small amount of money, and save a lot of money.
