Arrester ground lead monitoring and early warning device and arrester ground lead monitoring and early warning method

Abstract

The invention provides an arrester ground lead monitoring and early warning device and an arrester ground lead monitoring and early warning method. The arrester ground lead monitoring and early warning device comprises an outer shell, a central processing unit, an equipment monitoring unit, an alarm device and the like. The arrester ground lead monitoring and early warning method comprises the steps of detecting the resistance of a ground lead by use of a resistance detector, recording occurrence times of thunder currents in the ground lead by use of a pulse inductor, and the like. The arrester ground lead monitoring and early warning device and the arrester ground lead monitoring and early warning method can be used for performing real-time monitoring and early warning on the ground lead of a lightning conductor, conveniently and reliably, solving the operation and maintenance problems of the arrester ground lead, improving the safety, and avoiding equipment damage or pedestrian safety hidden danger during thunderstroke caused by undiscovered ground lead damage; meanwhile, the arrester ground lead monitoring and early warning device and the arrester ground lead monitoring and early warning method can be used for recording and accounting the thunderstroke frequency, ensuring that personnel can inspect lines with frequent thunderstrokes conveniently and prevent hidden dangers. The arrester ground lead monitoring and early warning method can be used for performing effective and comprehensive monitoring and early warning, and avoiding careless omission, and has a relatively good accounting effect.

Description

technical field [0001] The invention relates to the field of lightning protection facilities, in particular to a monitoring and early warning device for grounding leads of lightning arresters. Background technique [0002] At present, pole-mounted lightning arresters have been quite popular in lightning protection facilities. It is connected between the line and the earth. When a high transient overvoltage occurs due to lightning strikes, it will act, and the current will be introduced into the earth through the grounding lead. Once the grounding lead is affected by the environment, weather, If factors such as wear and aging, man-made damage and other factors are disconnected from the grounding electrode, the arrester will lose its function, which may cause the operating equipment to be struck by lightning, and pedestrians must be prohibited within 8 meters around when lightning strikes. In this way, the safe operation, maintenance and judgment of the grounding lead is parti...

[0002] At present, pole-mounted lightning arresters have been quite popular in lightning protection facilities. It is connected between the line and the earth. When a high transient overvoltage occurs due to lightning strikes, it will act, and the current will be introduced into the earth through the grounding lead. Once the grounding lead is affected by the environment, weather, If factors such as wear and aging, man-made damage and other factors are disconnected from the grounding electrode, the arrester will lose its function, which may cause the operating equipment to be struck by lightning. Pedestrians must also be prohibited within 8 meters around when lightning strikes

In this way, the safe operation, maintenance and judgment of the grounding lead is particularly important. However, at present, the grounding lead of the lightning arrester is completely inspected and operated by personnel. good stats
