How does the building protect the thunder?
Buildings can not prevent lightning strikes, but can lead the lightning current to the earth safely, thus causing no damage to buildings, personnel and electrical equipment.The roof will be erected lightning rod, and some new construction, in order to beautiful, do not use lightning rod, but there must be a lightning belt. The lightning belt is a steel bar above the top of the roof wall. It will circle around the top of the building and be connected to the 10cm. Some lightning protection requirements of the building, but also the use of lightning nets, erected in the upper part of the roof to form a network structure.Some of the roof is more beautiful, do not use the bright lightning belt, but the lightning bar reinforcement buried in the roof of the fence inside, but only a thin layer of covering, almost no impact on the mine. But the outward appearance does not look out to have the steel bar.After the roof is connected to lightning (that is, to draw lightning), the metal frame is connected through the upper and lower layers of the building body to bring the lightning current to the ground. All the steel bars in the building are electrically connected and can be bound with wire, but it is better to weld them and then pour cement.
Electrical equipment lightning protection, do not expect to install one or two lightning arresters to solve all lightning protection equipment at home. It is best to install separate lightning arresters for each home appliance. However, generally, the most vulnerable to thunder are TV sets, computers, etc., followed by air conditioning.
Building lightning protection is generally only the installation of lightning rod, lightning belt, etc., but now the building is generally reinforced concrete structure, lightning strikes directly, on the situation is not seen. Building lightning protection, you can find the local weather bureau lightning protection advisory or configuration.
