Heavy rain and lightning raged in Shanghai, and lightning struck the Oriental Pearl Tower. Is the lightning protection device useful?
Lightning rods are useful. The reason why the Oriental Pearl Tower in Shanghai was struck by lightning is because it is relatively high and is more likely to attract lightning. At the same time, because its material contains iron, it is more likely to be struck by lightning. . 1. Torrential rain and lightning are raging
In this news, the reason why the Oriental Pearl Tower in Shanghai was struck by lightning is that I personally think it is because the heavy rain this time covered a large area and the thunder and lightning was relatively complicated. The reason why it hit him was not because the lightning rod was useless. Because of the recent typhoons, Shanghai, a coastal city, has been greatly affected. In this heavy rain, Shanghai not only suffered heavy rainfall, but also thunderstorms. Under such circumstances of lightning and thunder, it is normal for the Shanghai Pearl Tower to be struck. This is a probabilistic event and cannot be completely avoided by having a lightning rod. The main function of a lightning rod is to guide lightning into the ground. It’s not about protecting buildings from lightning strikes. The probability of being awarded the Oriental Pearl during such a large-scale thunderstorm in Shanghai has been increased because the cumulative number has increased. 2. The function of lightning rods
The main function of lightning rods is to protect people’s lives and the integrity of buildings. Therefore, the function of lightning rods is to guide lightning into the ground, not to prevent buildings from being struck by lightning. The lightning rod is an iron needle. This iron needle can guide lightning to the needle, and is connected to the copper wire under the iron needle to guide the lightning into the ground. In this way, the lightning strike will not cause damage to the building, because the lightning strikes Architecturally, it can create sparks. At the same time, lithium batteries also have a certain amount of energy. When lightning strikes a building, it will not only burn the building, but it also contains huge power. Without lightning rods, such tall buildings would be extremely risky.
To sum up, lightning rods are useful, but it is only because thunderstorms in Shanghai are too wide and severe that this situation occurs.
