摘　　要：针对干旱地区电气化铁路钢轨电位偏高现象,研究其钢轨电位限制方案。在自耦变压器供电方式下,利用Matlab/Simulink软件建立了牵引回流系统的仿真模型。通过仿真分析可知,高泄漏电阻是影响干旱地区铁路钢轨电位升高的重要原因;在高泄漏电阻时,对供电区段设置保护连接线及贯通地线可以降低干旱地区铁路钢轨电位。In allusion to abnormal potential arising of steel rail of electrified railway located in arid regions,the measures to restrict steel rail potential are researched.A Matlab/Simulink-based simulation model of traction return system supplied by autotransformer feeding system is built.From simulation results it is known that the higher leakage resistance is the main reason lead to steel rail potential arising in arid regions,thus under the condition of higher leakage resistance in arid regions the abnormal arising of steel rail potential of electrified railway can be restricted by configuring the connector of protective wire and the thoroughly connected ground wire in power supply section.
