The study on short circuit test for traction power supply system of Passenger dedicated Line

The preconditions, procedure, method and attention items of the short circuit test are studied in this paper, and the measured data and the evaluation standard are analyzed by taking the implementation in Beijing-Tianjin Passenger Dedicated Line as example, which can be the standardized reference model. Through the actual application and analyzation of Beijing-Tianjin Passenger Dedicated Line, it is confirmed that the short circuit test of traction power supply system is indispensable in the phase of integration test. The installation quality, system function and system performance of traction power supply system can be verified and optimized by means of the standardized and actual short-circuit test.
