Is it true that buildings with lightning rods will not be struck by lightning?

Why can lightning rod prevent lightning strike? In fact, in theory, as long as the lightning rod and the height of the house have certain indicators, they are generally high-rise buildings. If you encounter a thunderstorm and lightning strike, it is not easy to choose the person next to the house first, just aim at the lightning rod at the highest peak, because it is a metal composite material and is easy to conduct electricity. Therefore, we can master the lightning rod as a lightning rod, which is quite a kind of fantasy novel to help people improve the actual effect of Buddhism.

After lightning strikes the lightning rod, the lightning rod will introduce the German power of lightning into the grounding grid according to the down lead connected to it. So far, people in construction projects will not be damaged by lightning, so it can play a practical role in maintaining the inside and outside of buildings. However, this is only the actual effect of basic knowledge. In detail, the development trend of anything is not easy to move towards the ideal development trend. Most lightning strikes are still important to catch random targets. Although lightning rods can be prevented, the probability is not too great and the important range is too narrow. Therefore, many construction projects have slowly installed lightning protection belts.

The function of lightning protection zone in metropolis under lightning corrosion is similar to that of lightning rod, but it can be regarded as the second layer of protection. When lightning ignores the lightning rod, it will easily hit the lightning belt. The latter one can also make full use of the same practical effect and introduce the total current into the grounding grid for drainage to reduce the damage of lightning to people and buildings. So, do high-rise buildings have to be equipped with lightning rods? The response was: "Yes!" In fact, lightning also has a principle of being far away. Generally speaking, it likes to demolish tall buildings, and it is very conductive. After that, the flowers and trees in the middle and lower floors (four or five floors) were split, and finally the single-floor square meter was split, and finally the people were split. But everyone is worried about learning the fate of lightning chopping with their lives, just like the classic flag in TV series. Opening your mouth and closing your acne is lightning chopping.

In addition to personal safety, lightning also has certain risks to the building itself. When standing upside down, it is easy to cause damage to internal electrical equipment, and short circuit faults are common, leading to safety accidents. Nowadays, buildings are moving towards intelligence, and there are many internal circuits. Once the internal circuit is damaged by lightning, the maintenance cost is also very amazing. Therefore, the design of lightning rod and lightning protection grounding system must be a compulsory course for all high-rise buildings. What is important today is to avoid lightning, or the above-mentioned leakage and resistance. Leakage refers to the lightning rod leading lightning to the grounding grid. If it is resistant to electricity, it is necessary to improve the hard power of the construction project itself. Just like the airport under lightning, I still stand in the sky even if I am hit by lightning. This is the lightning protection raw material of the airport itself, which can play a practical role in lightning protection. Finally, I will tell you how to install the lightning rod.

Its lightning protection belt, that is, the needle cylinder of lightning rod, is generally made of copper, tinned copper, aluminum, aluminum profile or stainless steel plate. Iron is the most common raw material of old lightning rod, but pig iron is very easy to be oxidized, which will rot after a long time in the sun and rain, and will destroy its characteristics after many years. Metal products, on the other hand, are not easy to rust, so copper raw materials are usually chosen because of their excellent conductivity and are not easy to rust. Nowadays, many circuit wires are copper-core cables. In addition to the raw materials for connecting the lightning protection belt, its diameter is also very harsh, not less than 8 mm
