摘要
轨道电路在铁路信号系统中属于故障率较高的设备,而钢轨中不平衡牵引回流的存在会对轨道电路产生干扰,大大增加了轨道电路的故障率。该文针对不平衡牵引电流对轨道电路的干扰,从轨道电路抗干扰角度入手,研究轨道电路抗不平衡牵引回流干扰的方法,从而减小轨道电路的故障率,提高轨道电路的可靠性。
Track circuit in the railway signal system belongs to the high failure rate of equipment,while the existence of imbalance in the rail traction return can produce interference of track circuit,greatly increase the failure rate of track circuit.This article in view of the unbalanced traction current interference of track circuit,from the perspective of track circuit anti-interference of the unbalanced traction reflow interference of track circuit,the method of reducing track circuit failure rate,improve the reliability of track circuit.
