近年来我国高速铁路运营速度不断提高，牵引供电系统对信号系统的电磁影响问题也相应加剧。以牵引回流对信号电缆产生的电磁影响为对象，分析并计算了高速铁路牵引回流在信号电缆上产生的纵向感应电动势，结合对大量实测数据的统计和总结，分析了列车正常运行与特殊工况下牵引回流对信号电缆产生的电磁影响，以及不同条件下信号电缆感应电动势的特性关系。

With the constantly improving speed of the high-speed railway in recent years, the situation of the electromagnetic effect on railway signal system by the traction power supply system has become ever more serious. This paper takes the electromagnetic effect on the signal cable by the traction current as the object. Longitudinal induced electromotive force of the signal cable’s core line caused by the traction current in high-speed railway was analyzed and calculated. Through statistics and summary of mass testing data, we made a comprehensive analysis of the electromagnetic effect on the signal cable by the traction current both in normal operation and special condition. Characteristic relation of longitudinal induced electromotive force with various influencing factors was analyzed as well.
