| Abstract: | 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. |
