Electromagnetic analysis of pantograph catenary off-line in train over Neutral-Zone

Abstract

During the operation of the electrified railway, the location of the train through the Neutral-Zone area will appear obvious electromagnetic disturbance phenomenon. In this paper, by analyzing the circuit structure of the Neutral-Zone, the circuit simulation model is constructed and the data of the disturbance voltage is obtained. The data is measured on the cable of the EMU and the simulation results are confirmed. At the same time, Through the construction of the analog discharge platform to study the phenomenon of off-line arc generated electromagnetic disturbance, get the real discharge data, get the real discharge data. Finally, through the electromagnetic simulation software, the arc net off-line equivalent antenna radiation simulation modeling, And the spectrum distribution of electromagnetic disturbance is analyzed.
