摘　　要：扼流适配变压器结构简单,可靠性高,安装较为简便,维护工作量小,具有显著的抗干扰效果,在客专一体化轨道电路中得到广泛应用,但轨道电路设备受器材故障、牵引回流及外界因素的叠加影响,在处理轨道电路红光带故障时往往延时较长,原因查找不清。以常见的扼流变压器隐患为例,对客专轨道电路扼流变压器常见故障进行分析和总结。Impedance transformers have the advantages of simple structure,high reliability,simple installation,small maintenance workload and remarkable anti-interference effect.They have been widely used in the integrated track circuits of passenger dedicated railways.However,the track circuit equipment is aff ected by material failures,traction return currents and external factors.When dealing with red-light straps of track circuits,the delay in troubleshooting is often long and the causes are often unclear.This paper analyzes and summarizes the common faults in the impedance transformers in the track circuits of passenger dedicated railways,taking common potential dangers of the impedance transformers as examples.
