| Abstract: | ZPW-2000 track circuit is one of the key devices of railway signaling system,and its components are easily affected by the traction current and its harmonics during normal operation.When the train runs at 400 km/h or even higher,its traction power will continuously increase,which accordingly increases the interference of the traction current and its harmonics in the rails to the track circuit.This paper analyzes the influence of unbalanced traction current,traction current and harmonics of 400 km/h high-speed railway on track circuit,proposes the adaptability schemes for air-core coil and impedance transformer of the track circuit,and puts forward the requirements for harmonic limit of EMU traction current when ZPW-2000 track circuit works reliably. |
