摘要： 针对隐蔽且易发生的轨道电路红光带故障，通过排查发送、接收通道等，采集实时数据分析干扰信号，得出发送器发码通道与区间直流电源混线导致干扰本站同载频其他区段，引发小轨出电压波动造成闪红光带故障。通过案例分析总结该类故障特点，提出防范措施及处置方案。

关键词: 红光带, 小轨出电压波动, 通道混线, 同频干扰

Abstract: Aiming at the hidden and red-light strap faults of track circuit, by investigating the sending and receiving channels, collecting real-time data and analyzing the interference signal, it is concluded that the mixed line of the code sending channel of the transmitter and section DC power supply causes interference to other sections of the same carrier frequency of the station, and causes the voltage fluctuation of the short rail to flash red-light strap. Through case analysis, the characteristics of this kind of fault are summarized, and the preventive measures and disposal scheme are put forward.


Key words: red–light strap, output voltage fluctuation in short track circuits, channel mixing, same frequency interference
