摘要
针对目前电力系统检修作业中挂、拆接地线存在的安全问题,介绍了一种新型电力检修地线系统。该系统采用了高频电源供电的方式,基于电流分流特性进行地线检测,并使用GSM无线数据网络传输接地信息,有效防止带地线送电事故。
In view of the security issues arising from hanging and removing of the grounding line in the overhaul work at present,this paper introduced a new type of detecting system for grounding lines,This system,using high-frequency power supply and based on current shunt characteristics,is able to detect grounding lines effectively,and transmit the grounding data through the GSM wireless data networks,and therefore it can effectively prevents accidents resulting from the grounding line.
