扼流适配器抗轨道电路电气化干扰浅析

Analysis of Choke Adapter Against Track Circuit Electrification Interference

随着近年来铁路的高速、重载发展,电气化铁路已经占据了大部分份额,由于参与列车信号控制的轨道电路设备、带动列车运行的动力设备均需要通过钢轨传导电流,所以电气化铁道干扰对信号系统的影响是不能完全避免的。目前,扼流变压器增设适配器的方式对电气化的干扰还是有比较显著的效果,本文主要结合工作原理对扼流适配器如何抗轨道电路电气化干扰进行简要分析。

In recent years,with the development of high-speed and heavy-haul railway,the electrified railway has occupied most of the share.Since the track circuit equipment that is involved in the control of train signals and the power equipment that drives the train operation need to conduct current through the rail,the impact of electrified railway interference on the signaling system can not be completely avoided.At present,the method of adding an adapter to the choke transformer still has a significant effect on the electrification interference.In this paper,how the choke adapter against track circuit electrification interference is briefly analyzed according to the working principle.
