摘　　要：地埋电缆普遍被应用于通讯等诸多领域,地埋电缆漏电现象普遍存在,查找解决的方法也不尽相同,本文所探讨的是利用接地电阻测试仪,查找确定中卫大地电场台地埋电缆漏电位置的方法,简单易行,能够快速准确的排除故障,从而使观测系统正常工作。尽可能减少因漏电产生的非地震异常数据量。Buried cable is commonly used in communications and many other fields. The electric leakage phenomenon of the buried cable is widespread. The search solution method is also different. In this article, the method by using the earth resistance reflector to search and determine the leakage position of the buried cable in Zhongwei station is discussed. The method is simple and feasible and can also eliminate faults fleetly and accurately to make the observing system work normally and reduce the non-earthquake unusual data quantity which produced by electric leakage.
