This article gives you a talk about wireless charging lightning effect, as well as wireless charging rx corresponding knowledge points, I hope to help you, don't forget to collect this site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Will you hit your computer with a wireless router
1, the laptop through the wireless router Internet, thunder, will not hit the laptop, because the energy of lightning can only spread in the line, can not cross a certain distance, through the radio wave transmission, so do not worry. Wireless router is a router used for users to access the Internet with wireless coverage.
2, wireless relative to the wired network, will not be struck by lightning, because the optical fiber (light signal) does not conduct electricity. If the wireless router front end uses fiber cat Internet access will not be lightning patronized, there is no wire to connect the computer. Lightning protection: lightning frequent places, try not to close to the window (especially with steel bars), do not surf the Internet has also been reported by lightning.
3, there are many forms of lightning strikes, in addition to direct lightning, there are inductive thunder. If the sensor mine is high voltage on the grid, and it comes in through the power lines, the computer could still burn up. The most reliable way is to shut down, disconnect the power supply, network cable, etcConnect the wire.
4, also. In extreme conditions, high up, with no buildings (tall objects) around. The resistance (ionization) of the communication pipeline established by the computer when communicating with the route will be lower than the surrounding environment, and in the lightning environment, it will guide the lightning to attack the computer and the route. The same goes for not talking on your cell phone outside, including during thunderstorms.
5, and the sockets in the home are grounded, you can use a multimeter to measure the leakage voltage of your computer and router, with the AC gear of the voltage, if displayed under 5v, it means that the ground is good, if it is higher than 5V, you need to check the socketTop, likely to cause lightning. ④ It is not appropriate to contact metal objects such as gas pipes and water pipes.
When thunder, the following appliances should not be used: Solar water heater: Its heating and control system is quite complex, easy to introduce lightning damage. Air conditioner: The outdoor unit is prone to lightning. Therefore, lightning protection between the outdoor unit and the building lead, indoor air conditioner host, and power supply must be considered. Gas water heaters, refrigerators, range hoods, washing machines and other large household appliances: because of the long line and exposed to the outdoor part, it is easy to become the target of lightning strikes.
Solar water heater: Because of its heating and control system is more complex, easy to achieveLightning damage target. Air conditioning: Especially the outdoor unit part is easy to cause lightning, need to consider the lightning protection problem with the lead of the building, indoor air conditioning host and power supply. Large household appliances such as gas water heaters, refrigerators, range hoods, and washing machines: these household appliances have long lines and are exposed to more outdoor parts, which are easy to become lightning targets.
Therefore, it is recommended to avoid the use of air conditioning in thunderstorm weather, especially when the thunder is very close, but also pay attention to safety to prevent unnecessary damage caused by lightning. Secondly, in addition to air conditioning, other electrical appliances should also be reduced in thunderstorm weather. Due to electrical appliances with external power cordsElectrical appliances may be damaged if used during lightning. Therefore, in a thunderstorm, it is best to unplug electrical appliances to avoid damage to electrical appliances until the thunder is far away and then resume use.
To eliminate the counterattack phenomenon, two measures are usually taken: one is to make equal potential connection, connect two metal conductors with metal conductors, so that the potential is equal when they are connected to flash; The second is to keep a certain distance between the two.
Installing a lightning arrester: Install a lightning arrester at the end of the overhead lineThe device can absorb or limit lightning overvoltage to protect power equipment. Backup protection: Use operating overvoltage protection equipment as an additional protection measure for atmospheric overvoltage to ensure equipment safety. Reduce ground resistance: By reducing the ground resistance of the tower, the counterattack phenomenon is reduced and the system is protected from damage.
In order to completely eliminate the destructive potential difference caused by lightning, it is especially necessary to implement equal potential connection, power lines, signal lines, metal pipes, etc. should be connected through the overvoltage protector for equal potential connection, the interface of each inner protection area should also be connected according to this local equal potential connection, and finally connected with equal potentialConnect to the busbar.
Lightning contact device: By installing lightning rod, lightning belt, etc., guide lightning into the ground through the predetermined channel, reduce the damage to the building and equipment. Equipotential connection: power lines, signal lines, metal pipes, etc. are connected through overvoltage protectors to eliminate potential differences generated by lightning. Shielding: The use of conductor materials such as metal mesh, foil, shell or pipe to surround the protected object and block the intrusion path of lightning electromagnetic pulse waves.
