Thunderstorm raged in Shanghai, and lightning struck the Oriental Pearl. Is the lightning protection device useful?
1 Thunderstorm raged in this news, and the Oriental Pearl Tower in Shanghai was struck by lightning. Personally, I think it was because the rainstorm covered a large area and the lightning was complicated, so it was hit by lightning, not because the lightning rod was useless. Shanghai, a coastal city, has been greatly affected by the recent typhoon. Moreover, in this rainstorm, Shanghai not only suffered heavy rainfall, but also thunderstorm weather. It is normal that the Shanghai Pearl Tower was split under such lightning. This is a probabilistic event and cannot be completely avoided by lightning rods. The function of lightning rod is mainly to guide lightning into the ground, rather than to prevent buildings from being struck by lightning. In such a large area of thunderstorm weather in Shanghai, the winning probability of Oriental Pearl has increased, because the cumulative number of times has increased.
2, the role of lightning rod The role of lightning rod is mainly to ensure the safety of people's lives, but also to ensure the integrity of buildings, so the role of lightning rod is to guide lightning into the ground, rather than to prevent buildings from being struck by lightning. The lightning rod is an iron needle, which can guide the lightning to the needle, and connect the copper wire under the iron needle to guide the lightning underground. In this case, lightning strike will not bring harm to the building, because lightning strike will split sparks from the building. At the same time, lithium batteries also have some energy. When lightning strikes a building, it can not only burn the building, but also contain great power. If there is no lightning rod, that tall building will be very dangerous.
To sum up, the lightning rod is useful, but it is only because the thunderstorm weather in Shanghai is too extensive and serious that such a situation has appeared.
