There are many thunderstorms in summer, but many high-rise residential residents think that lightning protection devices have been installed on the buildings, and there is nothing to worry about. actually it is a kind of misunderstand. On July 8, a lightning protection expert in Beijing told reporters that if high-rise residential buildings are equipped with solar water heaters, satellite TV receivers, air-conditioner outdoor hang-ups, solar panels, etc., special attention should be paid to lightning hazards, and these devices may “lead into the room”. ", damage to the personal and property safety of residents."

Although most of China's high-rise residential buildings are equipped with lightning protection devices on the roof, they cannot eliminate lightning by 100%. The solar water heater installed on the roof is likely to be the target of lightning strikes, and the current will enter the room along the pipes of the solar water heater or the water in the pipeline. At this time, if the residents happen to be bathing, washing their hands or touching the metal faucet, they may encounter lightning strikes. Experts suggest that residents should install lightning protection devices for solar water heaters in time after installing solar water heaters on the roof, and ask professional organizations to check and test performance. At the same time, try not to touch the solar water heater pipe and its attached auxiliary equipment during thunderstorms.

The natural phenomenon of thunder and lightning can be said to be ever-changing. Generally speaking, for high-rise houses with a height of more than 60 meters, although lightning protection devices are installed on the roof, there is still the possibility of encountering lightning strikes, that is, lightning is not being used. The top lightning protection device is directed to the ground, but bypasses the lightning protection device and directly hits the side of the building. At this time, it is very dangerous for residents who install solar water heaters, satellite TV receivers, and outdoor air-conditioners on the outside of the balcony. Lightning will enter the room along the connecting lines of these devices. What kind of consequences will be unpredictable in the end. Lighter people will damage the household appliances and injure the households. Serious people may not only cause personal injury or death, but may also cause fire. Experts suggest that high-rise households should carefully install the above equipment on the outside of the balcony. If installation is required, professional personnel should be required to design and install lightning protection facilities to avoid personal injury or property damage. (Zhang Lei)
