摘　　要：针对某城市轨道交通B2型车辆计轴红光带干扰问题,采用Maxwell仿真试验以及现场试验结合的方式,以牵引逆变器及辅助逆变器两个大型变流设备为切入点,探究了不同出线布置方式、工作模块数量、负载、DC/DC开关频率对轨道计轴设备的干扰。研究表明大电流线布置方式、高频辅助逆变器DC/DC开关频率变化会对计轴设备产生影响。并基于干扰原因提出应对策略,为既有线路红光带干扰问题提出改善建议,并对未来轨道车辆变流设备设计提供思路。Aiming at the problem of the red light band interference in the axle recording of a B2 urban rail transit vehicle,a combination of Maxwell simulation experiment and field experiment was adopted,and the traction inverter and auxiliary inverter were used as the entry point to explore the differences.The interference of outgoing line layout,number of working modules,load,and DC/DC switching frequency on track axle counting equipment.Studies shows that the high-current line layout and high-frequency auxiliary inverter DC/DC switching frequency changes will affect the axle counter.The countermeasures are proposed based on the cause of the interference,and the improvement suggestions are provided for the red-band interference of the existing lines,ideas are provided for the design of converter equipment for rail vehicles in the future.
