Simple and easy grounding grid overhauling device

Abstract

The invention provides a simple and easy grounding grid overhauling device. The simple and easy grounding grid overhauling device comprises an overhauling grounding mechanism and a maintenance electric welding machine capable of maintaining faults, wherein the overhauling grounding mechanism comprises a grounding rod A with a grounding function, a grounding rod B with the grounding function and an insulating clamp with an insulating function; the grounding rod A and the grounding rod B are provided with iron pieces. Aiming at the problem of existing technical equipment that a grounding line is released from a grounding body or a grounding grid to generate electricity leakage; the overhauling grounding mechanism and the maintenance electric welding machine capable of maintaining the faults are adopted, so that the contact voltage and the step voltage can be obviously reduced; a lot of fault power supplies flow into the ground from the grounding grid to a vertical electrode so as to correspondingly reduce the scattered flow of a horizontal conductor.

Description

technical field [0001] The invention relates to the technical field of grounding grid power maintenance, in particular to a simple grounding grid maintenance device. Background technique [0002] In recent years, with the rapid growth of the grid scale, the number of substations and lines has increased sharply. Due to the long-term operation of equipment, once the grounding body or grounding grid of some life-related substations, lines, and station area equipment corrodes and detaches, it will lead to major safety accidents. In this case, on the one hand, the operation and maintenance department is required to strengthen equipment inspection and maintenance; on the other hand, it is necessary to improve the efficiency of equipment maintenance through the use of simple grounding maintenance devices, so as to improve the safety and stability of equipment operation. [0003] When the substation and line equipment in operation are grounded due to lightning strikes or insulation...

AI Technical Summary

Problems solved by technology

The high-voltage substation or the high-voltage leakage of the line passes through the ground, which will cause the protection ground to trip, but if the equipment ground wire is separated from the ground body or the ground grid, it will generate step high voltage, which will endanger the safety of personnel; at the same time, once the equipment leaks, people touch Leakage of equipment will cause electric shock casualties. When electrical equipment leaks, if the power supply is not cut off in time, it will cause a short circuit fault and burn the equipment
