电气牵引电流对信号设备干扰原因分析及处置方案

Analysis and Disposal Scheme of Interference Causes of Electrifi ed Traction Current on Signaling Equipment

铁路电气化的普及后,电气化牵引电流对信号设备的干扰问题比较影响电气化铁路的正常运营.通过现场电气化牵引回流影响信号设备正常工作问题的处理,指出电气化设备在设计、施工、维护应该注意的问题,总结对该类问题处置的一般性方法,以降低对信号设备的影响.

With the popularization of railway electrification,the interference of electrified traction current on signaling equipment has affected the normal operation of electrifi ed railway.By dealing with the problems that the electrifi ed traction backfl ow affects the normal operation of the signaling equipment on the spot,This paper points out the problems that should be paid attention to in the design,construction and maintenance of the electrified equipment,and summarizes the general methods to deal with these problems,so as to reduce the infl uence on the signaling equipment.
