接触网故障测距系统在复杂接触网线路中的应用

Application of Catenary Fault Location System in Complex Catenary Lines

提出了一种基于行波的接触网在线故障监测方法,介绍了该系统的模块组成,克服了接触网冲击负荷取能以及故障启动问题,将该系统投入到上海铁路局某复杂结构供电臂中,系统故障测距结果表明,该故障测距方法相比站内测距方法具有更高的故障测距精度,为接触网故障测距提供了新方法以及有力的理论支撑。

This paper proposes an online fault monitoring method for catenary based on traveling wave,introduces the module composition of the system,overcomes the problems of impact load taking and fault starting of catenary,and puts the system into a power supply arm of a complex structure of Shanghai Railway Bureau.The fault location results of the system show that the fault location method has higher fault location accuracy than the internal distance measurement method.It provides a new method and strong theoretical support for fault location of overhead contact line.
