地电台地埋线缆高阻漏电点的简易定位装置
A simple device for locating high resistance leakage points in buried cable of geoelectrical station
摘要
Abstract
To locate the high resistance leakage points of the buried cables at the geoelectrical station,a simple device combining a megohmmeter and a multimeter is designed according to the principle of the differential potential method and the actual observation situation of the geoelectrical station.Based on theoretical calculations and on-site experiments at Xunxian Geoelectrical Station,it has been proven that this method can accurately and quickly locate the leakage points of the buried cables when the insulation to the ground of the buried cable is less than 300 kΩ,with a positional error of less than 1 m.This method uses the monitoring equipment in the general geoelectrical station,which is easy to operate and has the conditions to be extended to the geoelectrical station affected by high resistance and leakage of buried cables.关键词
