Abstract

The invention relates to a railway vehicle zero-voltage starting device, a control method and a railway vehicle, and the device comprises: a power receiving unit which is used for receiving the first DC voltage input of a pantograph and supplying power to a chopping unit; a chopping unit which is used for carrying out step-down chopping on the first direct-current voltage input to obtain second direct-current voltage output, wherein the second direct-current voltage is smaller than the first direct-current voltage; an inversion control unit which is used for controlling the main and auxiliary inverters under the power supply of the second direct-current voltage of the chopping unit; and a main auxiliary inverter which is used for converting the first direct-current voltage input by the pantograph into a first alternating-current voltage under the control of the inversion control unit and outputting the first alternating-current voltage through a medium-voltage bus. A charger does not need to be configured, extra time does not need to be consumed for charging the storage battery, and the running speed of the railway vehicle is increased.

Description

Technical field [0001] The present invention relates to the field of rail vehicle, and more particularly to a rail vehicle zero-pressure starting device, a control method, and a track vehicle. Background technique [0002] In the prior art, the wake-up starting mode of the rail vehicle is, and after the battery is powered by the battery, the train network control system is activated, and the auxiliary inverter is controlled, and the auxiliary inverter converts the current of the electrical bow input. DC / AC voltages required by each device of the rail vehicle, the system. [0003] When the battery life is decreased, the charging line failure or the track vehicle is stored for too long, it will cause the battery loss to the battery loss, affect the normal input operation of the rail vehicle. The battery is charged by the ground charger, until the battery charging is completed. This charging process is more complicated and needs to be configured, and the charging is waiting for a ...
