Among the total tripping times of high-voltage transmission lines in my country, accidents caused by lightning strikes account for about 55%-75%, especially in areas with frequent lightning activities, high soil resistivity and complex terrain. The incidence of accidents caused by lightning strikes on transmission lines is higher, and the economic losses caused are very huge. Therefore, in the design of overhead transmission lines, research on lightning protection design is very necessary.

[0003] During the installation of the lightning protection grounding device, in order to ensure the stability of the main body, it is necessary to dig a foundation pit in advance on the ground, and then bury the concrete foundation block to fix the connecting ground wire, so that the lightning protection grounding device can be firmly fixed on the ground to resist the action of external forces.

When the equipment is shaken by wind or other external conditions, it is easy to cause the connection between the connecting ground wire and the grounding device to break, causing the grounding device to lose its original function. In order to solve this problem, a power grid lightning protection grounding device is specially proposed. Utility Model Content
