矿山电力电缆故障点的简易测距技术

Simple Ranging Technology for Fault Point of Mining Power Cables

电力电缆在运行过程中难免会因为各种原因发生故障,影响正常供电。由于电缆发生故障后外观无明显变化,查找故障点十份困难;重点剖析了电缆线路故障的性质以及故障点的测距方法。

During operation,power cables will inevitably fail because of various reasons,which affect the normal power supply.There are no significant changes in appearance after the failure of the cables,therefore,it is difficult to find fault.The paper focuses on analyzing the nature of the cable line fault and ranging method for fault point.
