摘要
在自动闭塞区段上区间广泛使用ZPW-2000A轨道电路,由于接收器(5A)断路器断开后导致区间轨道电路红光带问题所引发的故障近两年逐年增加。为提高ZPW-2000A轨道电路设备可靠性、安全性。结合接收器设计原理,经过无数次参加现场天窗修实践调研模拟故障现象,说明接收器(5A)断路器断开后的故障原因、故障现象和电路的改进措施。
ZPW-2000A track circuits are widely used in automatic block sections.The faults caused by the red-light strap problem in the track circuits in the sections after the disconnection of the receiver(5A)breakers have increased year by year over the past two years.To improve the reliability and safety of ZPW-2000A track circuit equipment,this paper explains the fault causes,the fault phenomena observed after the disconnection of the receiver(5A)breakers and the improvement measures for the circuits.The analysis presented in this paper is based on the design principles of the receivers,as well as extensive fi eld research conducted during track possession and simulations of the fault phenomena.
