- Abstract
ZPW-2000 track circuit is the basic key equipment of railway signaling system. When the train running speed is increased to 400 km/h or even higher, the interference of the traction return in the rail and its harmonics to the track circuit equipment will also increase. Firstly, based on the train resistance model and the parameters of the standard EMU, in this paper the theoretical calculation of the traction power and traction current of the Chinese standard EMU at a speed of 400km+ is completed. Secondly, based on the calculation results of the traction current, the selection analysis of track circuit choke transformer and air core coil and other outdoor equipment is completed. Finally, based on the calculation results of unbalanced traction current, the impact analysis of harmonic interference on the track circuit system is completed.
