GUO Xugang
Abstract：In order to optimize the protection of high-voltage system of EMU,this paper discusses in detail the theoretical model of inrush current and measurement data of random no-load closing of China standard EMU traction transformer.It also comparatively analyzes the characteristics of China standard EMU inrush current and the voltage characteristics of the primary side of the transformer and its influence.Through the measured data analysis,it is found that the proposed method could reduce the inrush current caused by the EMU main circuit breaker frequent closing so that it could improve the protection of the EMU high-pressure system.Meanwhile,it provides the technical support for the selection of key components and the main circuit design of the highvoltage system of EMU.
