Background technique

Lightning protection device refers to the sum of lightning terminals, down conductors, grounding devices, surge protectors (SPD) and other connecting conductors. Generally, the lightning protection devices of buildings are divided into two categories - external lightning protection devices and internal lightning protection devices. The external lightning protection device is composed of the lightning terminal, the down conductor and the grounding device, that is, the traditional lightning protection device. The internal lightning protection device is mainly used to reduce the lightning current and its electromagnetic effect inside the building, such as electromagnetic shielding, equipotential connection and installation of surge protector (SPD), etc., to prevent possible damage caused by lightning electromagnetic pulse.

The grounding device is an important part of the lightning protection device. The grounding device discharges the lightning current to the ground, limiting the voltage of the lightning protection device to the ground from being too high.

The grounding device is a grounding set to eliminate the dangerous effects of overvoltage, such as the grounding of lightning rods, lightning conductors and lightning arresters. Lightning protection grounding can only flow current under the action of lightning strike. The amplitude of lightning current flowing through the lightning protection grounding electrode can reach tens to hundreds of thousands of amperes, but the duration is very short.
