Method and device for judging whether grounding wire works normally or not

Abstract

The invention provides a method and a device for judging whether a grounding wire works normally or not, and aims to solve the problems that in the prior art, grounding fails difficultly due to hardware structure design, but real-time monitoring is not available, high-altitude operation lasts for two or three days sometimes, a grounding drill rod may not be correctly grounded due to external force, and if real-time monitoring is not available, the grounding wire cannot be correctly grounded. And the grounding is not found by the personnel, so that the life safety is seriously endangered. From the perspective of reverse thinking, firstly, the grounding reliability is guaranteed from the perspective of monitoring the grounding condition, and secondly, the grounding problem is converted into the problem of collecting the grounding resistance value. The grounding resistance detection circuit is arranged in the grounding drill rod, so that the resistance value of the grounding resistance can be detected in real time, and the resistance value is transmitted back to an upper computer through the wireless communication module. Whether the grounding resistor is in a normal range or not can be detected in real time, whether grounding is correct or not is judged, and an alarm system is arranged on equipment for timely feedback reminding.

Description

technical field [0001] The invention relates to the technical field of electric power operation and maintenance and electric power maintenance tools, in particular to a method and device based on judging whether the grounding wire works normally. Background technique [0002] Grounding wire is an important technical measure to ensure the personal safety of workers on electrical equipment. However, the ground wire is also an important aspect that leads to major personnel liability accidents in the power system. When working at heights, sometimes the grounding wire is not properly grounded, causing the staff to lose protection. [0003] Ground wire hook ground brazing is an essential tool for high-altitude operations, and it is the umbrella for the lives of high-altitude workers. Due to static electricity, leakage, etc., a large amount of current will be generated instantaneously. If the building or equipment does not implement grounding protection measures, it will cause dam...

Problems solved by technology

[0004] However, in the prior art, the stability of grounding grounding is generally improved through hardware design (see Chinese patents 202020508437.7, 201320265288.6, 201520027934.4, etc.), but considering that work at heights sometimes lasts for two or three days, portable grounding wires usually Hooked on the transmission line several meters or even tens of meters above the ground, due to the influence of wind and other factors, the grounding wire ground brazing will loosen or even fall off.

The safety protection function of the grounding wire is lost, which poses a serious threat to the personal safety of electric construction workers

At the same time, it also has the danger of falling objects to the ground personnel

Even a fixed structure that is very stable under normal conditions may not be properly grounded at some point, posing a major safety hazard
