Recently, Guangzhou often has thunderstorms and rainstorms. A few days ago, Guangzhou even issued guidelines. During the issuance and effectiveness of high-level typhoon (yellow, orange, red) and rainstorm (red) warning signals, all schools in Guangzhou should suspend classes without waiting for the notice of the education administrative department. The employing unit shall, according to the working place, nature of work and the need for disaster prevention and avoidance, arrange the staff to postpone work, leave work in advance or stop work. On a thunderstorm day, we must stay in a safe place. But even if home appliances are in a safe home, even if they are turned off, why do they suffer?
televisions and air conditioners are most vulnerable to lightning strikes.
The TV is the most vulnerable to lightning strikes. Many people turn off the TV directly with the remote control after watching it. At this time, the TV is still in standby state. Once there is a big thunder, the huge current generated instantaneously will enter the TV and set-top box along the power line and TV signal line, resulting in the destruction of the set-top box and TV.
As for air conditioners, because the compressors used for air conditioning refrigeration are often installed outdoors, they are easy to be struck by lightning, and the lightning will be introduced indoors to burn the main engine. Therefore, in thunderstorm days, the use of air conditioners should be stopped and the power should be cut off.
lightning protection of household appliances – power failure is the key
In a thunderstorm, the best way to protect household appliances from lightning is to cut off the power supply in time and thoroughly. This is the safest and most effective method. Other methods for protecting electrical appliances include:
1. Don’t call on a thunderstorm
2. The home appliances should be placed away from the window and kept a certain distance from the building’s outer wall and columns
3. Use sockets with lightning protection function
4. When installing the solar water heater on the roof, it is necessary to install an independent lightning rod, and in the case of lightning, it is better not to use the water heater to avoid and reduce the damage caused by lightning
5. Don’t listen to the radio while driving in a thunderstorm
