Harmonics of traction system could affect the normal operation of the track circuit in high speed railway. In order to understand the harmonic fully and to reduce the harm from harmonic, this paper analyzes the harmonic characteristics of the traction transformers and traction converters separately in theory. Furthermore, the harmonic characteristics are shown by simulation and on site test data.
Due to intensive cable arrangement in high speed EMUs, the work on crosstalk coupling between power lines to temperature sensor lines with groove is quite important. According to a specific cable arrangement on board in EMU, this paper deals with the influence of structure of groove, intersection angle and impedance of lines by electromagnetic simulation software which was based on Finite Difference...
Aiming at protect passengers with portable pacemaker, it is of vital importance to meet the standard in the design of EMU. In this paper, based on the theory of high voltage cable and electromagnetic protection, the model of high voltage cable passing through the compartment is established to simulate the magnetic flux density of the environment around the cable. In view of the actual situation, using...
