当电气化铁道多股道站场接触网发生短路故障时,牵引变电所故障测距装置不能确定故障所在站场股道,导致查找故障、排除故障时间过长,严重时会影响电气化铁路的安全可靠运行.以某电气化铁路含软横跨的典型站场接触网为研究对象,阐述了站场发生故障时的接触网关键节点电流分布情况.在此基础上,在站场接触网关键节点位置安装电压、电流采集单元,在牵引变电所配置站场接触网故障定位分析平台,实现含软横跨站场接触网故障区域和故障支路的定位.
Catenary Fault Location System for Electrified Railway Yard with Soft Suspension
When the catenaries of multi-track station yards of electrified railways encounters short circuit fault,the fault location device at traction substation cannot locate the fault site,which leads to extra-long time cost of finding and remo-ving the fault and even affects the safe and reliable operation of electrified railway.This paper takes the typical catenary of an electrified railway station with soft suspension as the object,and expounds the current distribution of the important nodes of the catenary in the station yard when the fault occurs.On this basis,the voltage and current acquisition units are installed on the important nodes of the catenary of the station yard,and the station yard fault locating analysis platform is configured at the traction substation to locate the fault area and the fault branch of the catenary of the station yard.
