摘　　要：正线牵引电流泄漏至车场导致轨电位异常,针对国内某停车场轨电位异常现象,进行实测和理论分析。结合国内车场供电回流方案及杂散电流的流通路径,不同于传统单向导通装置,提出了一种定向导通回流装置,有效解决车场轨电位异常问题,有利于车场杂散电流防护。Positive traction current leakage leads to abnormal rail potential in parking lot and depot. Aiming at the phenomena of abnormal rail potential in a domestic parking lot, a theoretical analysis according to measured data is made. Combining the scheme of traction reflux scheme and the path of stray current, a directional reflux conducting device is presented, in order to solve the problem of abnormal rail potential and stray current protection effectively in parking lot and depot.

关 键 词：轨电位 杂散电流防护 定向导通回流装置
