城市轨道交通计轴设备受干扰分析及解决方案

Analysis on Disturbance to Axle Counter Equipment of Urban Rail Transit and Its Solution

城市轨道交通系统采用交流供电模式时常发生牵引供电回流干扰计轴设备的问题,针对该问题,分析计轴系统工作原理,对某市域轨道交通线路发生计轴设备受扰问题进行监测、试验、分析,并提出有效的解决方案。

The problem of the disturbance to the axle counter equipment by the return current of traction power supply system is liable to occur while the AC power supply mode is adopted by the urban rail transit.With regard to this problem,the working principles of the axle counter system are analyzed.Monitoring,test and analysis are carried out for an urban rail transit line where the problem of the disturbance to the axle counter equipment is frequently occurred.The effective solutions are put forward as well.
