摘　　要：针对电气化铁路的几种牵引供电方式,介绍吸上电流比、上下行电流比、横联线电流比以及电抗法等4种常用接触网故障测距方法的原理及计算方法。结合现场短路试验数据,比较各原理计算结果,分析各自的适用条件,为接触网系统的故障类型判定及故障点查找提供依据。In view of the traction power supply methods for electric railways, the paper introduces the distance measurement principles and computational methods of common OCSs based on four approaches, namely, ascending current ratio, ascending-descending current ratio, paralleling-line current ratio and reactance. In combination of the field short-circuit test data and by comparing the computed result of each principle, the paper analyses their application conditions respectively, providing a basis to determine the fault type of the OCS and locate the fault point.
