摘　　要：北同蒲线既是国家重载运输通道,又是客车繁忙运输通道,信号工的应急处置和故障处理水平直接影响运输安全生产和效益,故将25Hz轨道电路故障处理方法做出如下总结,处理轨道电路故障应从机械室开始,从室内到室外,故障按性质分为开路和短路故障。现场25Hz相敏轨道电路有旧型、97型、JXW25型3种。Beitongpu Line is not only a national heavy-haul transport channel,but also a busy transport channel for passenger cars.The emergency treatment and fault treatment level of signal workers directly affect the transportation safety production and efficiency.Therefore,the fault treatment methods of 25Hz track circuit are summarized as follows.The treatment of track circuit fault should start from the mechanical room,from indoor to outdoor,and the fault can be divided into open circuit fault and short circuit fault according to its nature.There are three kinds of 25Hz phase sensitive track circuits in the field:old type,97 type and JXW25 type.
