铁路信号电缆接地故障的定位方法分析

Analysis of Positioning Methods for Grounding Faults in Railway Signal Cables

阐述电缆接地故障原因,探讨铁路信号电缆接地故障点定位方法,包括电桥法、冲击电流法、脉冲反射法、故障定位系统。如果接地故障比较严重,应该根据实际情况,合理选用检测方法。

This paper describes the causes of cable grounding faults and explores methods for locating grounding fault points in railway signal cables,including bridge method,impulse current method,pulse reflection method,and fault location system.If the grounding fault is severe,a reasonable detection method should be selected based on the actual situation.
