Abstract

The invention discloses a power supply electric cabinet for a train. The power supply electric cabinet comprises a control loop and a main loop. The control loop is composed of a liquid crystal display and two sets of redundant control systems. The main loop is composed of an alternating-current input circuit, a silicon-controlled rectifying circuit, an output filter circuit and a plurality of sensors. According to the power supply electric cabinet, self-check of input and output states, self-check of working conditions of all circuit boards and self-check of feedback in various operation processes are achieved, display of various faults and step prompt of fault elimination are achieved, the operation reliability of the train is improved, and drivers and maintenance personnel can carry out operation conveniently.
