摘要 电气化铁道的钢轨除了作为机车车辆的走行轨之外,还兼作牵引供电网络的回流导体。直接铺设在道床上的钢轨与大地间并没有良好的绝缘,部分牵引回流通过轨—地间的横向过渡电阻泄入大地,形成钢轨对地电位,有可能危及旅客和线路维护人员的安全。本文对钢轨电位的发生机理和降低钢轨电位的可能措施作了全面分析,可供电气化铁道供电工作者参考。 The track of the electric railway is not only used as a running rail for rolling stocks, but also as a return conductor for traction network. Since the rail is directly laying on the roadbed, the isolation between rail and ground is imperfect. Some leakage current from rail to ground occurs. It generates a voltage between rail and earth, and may damage to the safety of passengers and maintenance personnels. In this paper a theoretical analysis is carried out and the methods of compensation are discussed.
