摘要
针对机场场道灯电力电缆的工作特点及出现频率较高的对地短路或低阻故障等故障类型,提出了一种能在线检测并精确定位的方法--电位比较检测法。给出了该方法的检测原理及测试方法,现场使用效果十分理想。
Aim at the characteristics of power cable of track light in airfield and the types of failures of ground shortcut or low resistance that are frequently occurred, a potential comparison method, which is a method for on-line detection and accurate location, is proposed, the principle and test method are given for the stated method, of which field application effect is good .
