钢轨电位异常升高的原因及解决措施

摘要

Metro rail potential abnormality is an important factor affecting train safe and stable operation. The paper gives a brief introduction on current return system to rail, rail potential generation, and qualitative analysis of rail potential distribution. The reasons for rail potential abnormal elevation may be resulted in, some corresponding solutions for these reasons are put forward.%　　地铁钢轨电位的异常是影响列车安全稳定运行的重要因素。对轨道的回流系统、钢轨电位的产生进行了简单的介绍，并且定性地分析了钢轨电位分布，分析了可能导致钢轨电位异常升高的原因，最后针对这些原因提出了相应的解决方案。
