摘　　要：随着电气化铁路运营里程的不断增加,铁路牵引供电网络越发复杂。精准的牵引供电系统故障定位,是及时发现并排除故障的前提保障。电气化铁路牵引供电的分相设置于大型车站附近时,如无法在牵引变电所附近一侧设置分相,则较难进行牵引变电所的故障方向辨别以及故障测距。本文结合工程经验,深入分析车站分相异侧设置时几种常见故障的判别及定位方法原理,总结方案的适用范围以及优势与不足,为今后此类问题的故障定位方案提供思路。Along with the continuous increase of electrified railway operation mileage,the railway traction power supply network is becoming increasingly complex.Accurate fault location of the traction power supply system is a prerequisite for timely inspection and troubleshooting.When the phase separations of traction power supply for electrified railways are set near a large scale station,if it is not possible to set the phase separations on one side near the traction substation,it is difficult to identify the fault direction and distance measurement of the traction substation.The paper,with reference of the engineering experience,analyzes profoundly the principles of several common fault identification and fault location methods when setting of phase separation at different sides of a station,summarizes the scope of application,advantages,and disadvantages of the solutions,and provides ideas for future fault location solutions for such problems.
