电力电缆故障检测方法的分析

Analysis of Power Cable Fault Detection Methods

阐述电力电缆故障的原因和性质分类、常用的测试和故障定位方法。同时利用低压脉冲法和冲击高压闪络法,分析和判断确定高压电缆故障的类型和故障点,以快速查找电缆故障的位置。

This paper describes the causes and nature classification of power cable faults,as well as commonly used testing and fault location methods.Simultaneously using the low-voltage pulse method and the impulse high-voltage flashover method,analyze and determine the type and location of high-voltage cable faults,in order to quickly locate the location of cable faults.
