Can I surf the Internet in thunderstorm weather?

Question 1: Can I surf the Internet in thunderstorm weather? It is reported that personal computers now use dial-up Internet access and broadband Internet access. Because the computer is closely related to the network and power supply connected to it, the lightning protection of the computer is far more complicated than ordinary household appliances such as color TV sets and refrigerators, and it should be fortified where lightning may invade. It is understood that most home computers are not equipped with lightning arresters on modems, so more attention should be paid to lightning protection. In rainy days, in addition to not using the computer, you have to cut off the power supply. It is best to unplug the power socket and let it go completely without power, so as to avoid generating radio waves when lightning strikes. Activation circuit; In addition to cutting off the power supply, broadband internet users have to unplug the network cable at the interface of the network card; Dial-up users should unplug the telephone line to avoid lightning damage to the modem of the internet computer. In a word, we should take precautions at all the gates where lightning may invade. There are about 8 million lightning strikes every day in the world. The voltage of each lightning strike is as high as 10 billion to 65.438+0 billion volts, and the current intensity is 20,000 to 40,000 amperes. The strong electricity released by lightning will cause damage to power facilities, interruption of telecommunications, satellites and mobile communication services, fire accidents of flammable materials in coal, petrochemical, textile and other industries, and even more serious casualties. This paper mainly talks about the lightning protection scheme of indoor appliances, especially microcomputer. There are generally two ways for lightning to enter the room: from the power line and from the signal line. Electricity invades modern buildings, and we can see lightning protection devices. When a building is directly hit by lightning, a strong current is introduced into the ground along the grounding lead to prevent the lightning from damaging the building. We also need to take some necessary lightning protection measures indoors. Technically, we need to install lightning protection devices for power supply on computers, household appliances and communication equipment. But in fact, because high-rise buildings have relatively perfect lightning protection measures, users in buildings generally do not need to consider lightning protection from the perspective of power supply. The invasion of signal lines here is mainly caused by lightning surge caused by induced lightning. Induction lightning generally comes from lightning strike to the ground and cloud-to-cloud discharge, among which the induced surge voltage generated by lightning strike to the ground is large, and electronic information equipment within 500 meters may be damaged by it. According to the theory and practical experience of lightning electromagnetic pulse, it is proved that the damage of electronic computers and other information equipment is mainly caused by lightning induced surge voltage, which can introduce the induced surge voltage wave into the equipment through various signal leads and destroy its chips and interfaces. Therefore, signal lightning protection devices should be installed between signal lines. Specifically, we can take the following measures in the personal computer networking system: 1. Install signal lightning protection device between the access line of modem (including Cable Modem and xDSL Modem) and home signal line (such as telephone line). If you are proficient in electronic and electrical technology, you can buy TVS tubes to make a simple lightning arrester, which is the most economical. 2. If you use UPS as the uninterrupted power supply of microcomputer, it is suggested that you install a power arrester before UPS to protect UPS. Buy a modem with lightning protection function. This kind of modem may be a little expensive, so you should see its function clearly when you buy it.

Please accept it, thank you!

Question 2: Does it matter if the router is put indoors to surf the Internet in thunderstorm weather? Lightning protection generally includes signal lightning protection, induction lightning protection and direct lightning protection. At present, the facilities for preventing direct lightning strike in buildings are relatively complete, and the situation that lightning strikes the facilities in buildings directly is very rare. Signal lightning protection and inductive lightning protection should be weak points. Induction lightning strikes such as lightning entering through signal links and power supply lines often occur. Therefore, it is often said that it makes sense to completely disconnect the electrical equipment at home from the outside during a thunderstorm. If it happens to be in the lightning strike area and the lightning protection facilities in this area are insufficient, it is best not to use it in thunderstorm days. Otherwise, the equipment loss caused by lightning strike can only be compensated by yourself ~ ~

Question 3: Can I surf the Internet in thunderstorm weather? Is the place where you surf the Internet a minefield? In other words, have you ever heard that computers, telephones or their electrical equipment were damaged by lightning?

If not, it's generally fine.

If there is, you should pay attention. To turn off the power, the most important thing is to unplug the network cable.

Question 4: Can mobile phones surf the Internet in thunderstorm weather? Try not to answer the phone and use the mobile phone in thunderstorm weather.

Question 5: Can I surf the Internet in thunderstorm weather? Please, in the case of a 3Q thunderstorm, lightning may enter the computer along the power cord or telephone line, damaging the chip, interface and internet access equipment of the computer motherboard, resulting in hardware damage and communication failure. For laptop users, it is easy to cause personal injury accidents.

Question 6: Can I turn on wifi in thunderstorm weather? Hello.

It is best not to open it.

But most of them are fine. For safety reasons.

It's best not to turn on the computer and TV when it thunders in rainy days.

However, in recent rainy days, I have been using the national wifi.

Nothing will happen.

I think it's not bad.

The signal is also very good. There is a signal within 30 meters. And the equipment at home is used, so I don't feel stuck.

I ordered another white car in JD.COM. If you are afraid of being struck by lightning. You can try universal wifi.

Hope to adopt.

Question 7: It is generally no problem to use computers and wireless internet access in thunderstorm weather, so don't worry too much. You can turn off the computer when the lightning is particularly heavy, so don't use it.

Question 8: Can I surf the Internet with my laptop in thunderstorm weather? With wireless network card and battery, you can surf the Internet in thunderstorm weather. Don't worry, there is no problem! !

Question 9: Is it safe to surf the Internet in thunderstorm weather? It's better to be careful when it rains. If you have to surf the Internet in rainy days, you can try lightning protection cats. It's safer this way As far as I know, Huawei's lightning-proof cat can prevent 6KV lightning strikes, so you can go and have a look.
