摘　　要：首先分析电力牵引系统对信号系统干扰的三种耦合途径，指出轨道电路受到的传导性干扰是我们目前面临的最大问题。其次，指出只要两个系统各自采取措施，电磁兼容是可能的．最后，在指出相敏轨道电路和移频自动闭塞抗电化干扰具有优点的同时，提出应进行技术改进的几点参考意见。First,this paper describes three couple paths of EM interference between an electrical propulsion system and a signal automatic block system,and points out that a conductive interference imposed on a track circuit by the electrical propulsion system is a crux to signalling engineers.Then,it mentioned that a series of measures should be taken in the two systems separately to make them electric-magnetic compatible.Finally,several ideas are presented to enhance the anti-interference ability of automatic block systems.
