摘要

结合多年现场测寻电力电缆缺陷和故障的实际情况

分析了低压脉冲法、二次脉冲法、三次脉冲法、直流三次脉冲法等预定位方法和音频信号感应法、声测法、声磁同步法、跨步电压法等精确定位方法的测试原理、适用范围以及优缺点

比较了各检测方法的测试精度和可信度

指出在定位方法适当的情况下

精确度是现场选取电缆故障测寻方法的关键。最后

结合实践研究总结了针对不同电缆故障类型的相应的检测诊断方法

为今后电力电缆故障的快速查寻提供了工程理论依据。

Abstract

Based on the experience of field diagnosis of power cables faults

this paper analyzes the detection principles

application scope

advantages and disadvantages of such coarse location methods as low voltage pulse-echo method

twice pulse method

thrice pulse method

thrice DC pulse method

as well as such fine location methods as audio signal induction method

acoustic measurement method

magneto-acoustic synchronous method

and step voltage method.Their detection precisions and reliabilities are compared

respectively.Precision is considered the key factor for selecting a special field cable fault detection method if location method is appropriate.Moreover

different diagnostic method suitable for each power cable fault type is concluded to offer a reference for rapid detection and location of power cable faults.
