Traction auxiliary power supply integrated deflector

Abstract

The invention relates to an inversion device used in a high-speed motor train unit, in particular to a power-supply integral inversion device with pull assistance. The invention solves the problems that the pull inversion device and the assistance inversion device of the existing high-speed motor train unit are formed separately; the installation fixing is extremely difficult; the assembly and disassembly, the repair and maintenance, and trouble shooting and processing are not convenient; the repair and maintenance for an air cooling structure is also not convenient, and the like. The inversion device of the invention comprises a case; the case comprises a rectification circuit, a pull power-supply inversion device of an inverter circuit, and an assistance power-supply inversion device; the pull inversion device and the assistance inversion device are integrated in the same case and adopt modular structure in design; the pull power-supply inversion device and the assistance power-supply inversion device commonly use one rectification circuit formed by a rectification power module; a water cooling device is also internally arranged in the case. The invention solves the difficult problem of limited installation space under a vehicle and overcomes the power-supply complexity of the bus of a train with the assistance inversion device. A main functional module can be assembled and changed easily at the lower part and the lateral part and can be maintained conveniently.

Description

technical field [0001] The invention relates to a converter device for high-speed EMUs, in particular to an integrated converter device for traction auxiliary power supply. Meet the traction auxiliary power supply needs of EMUs. Background technique [0002] The traction converters and auxiliary converters on the existing high-speed EMUs are independent in structure and self-contained, and respectively complete the traction and braking control of the EMUs and the auxiliary load power supply of the EMUs. The installation space under the high-speed EMU is limited, and it is extremely difficult to install and fix the split traction converter and auxiliary converter under the high-speed EMU, and the cooling and circuit are scattered and inconvenient to arrange and connect. Both the traction converter and the auxiliary converter include a box body, a rectifier circuit, and an inverter circuit. The structure of the existing traction and auxiliary converters is not designed and ar...
