Problems solved by technology

[0004] However, in the prior art, the internal combustion power system and the electric power system of the double power source EMU are integrated together, and are arranged on the same car body, and the axle load is relatively large, so it cannot be applied to the current domestic passenger dedicated line. The main circuit of the power source EMU cannot be applied to the decentralized power EMU, and the control strategy cannot realize the conversion between the internal combustion power system and the electric power system of the decentralized power EMU

Abstract

The invention provides a traction circuit of a dual-power source motor train unit, and belongs to the technical field of a motor train unit traction system. The traction circuit of the dual-power source motor train unit comprises an internal combustion power supply circuit, a traction variable current circuit and an electric power supply circuit, wherein the internal combustion power supply circuit is connected with the first end of the traction variable current circuit; the second end of the traction variable current circuit is connected with the electric power supply circuit; the internal combustion power supply circuit, the traction variable current circuit and the electric power supply circuit are arranged on different train bodies of the dual-power source motor train unit. The traction circuit of the dual-power source motor train unit provided by the invention has the advantage that the switching of a disperse power type motor train unit between an internal combustion power system and an electric power system is realized.

Description

technical field [0001] The invention relates to the technical field of the traction system of an EMU, in particular to a traction circuit of an EMU with dual power sources. Background technique [0002] At present, there are still a large number of non-electrified lines in China, which are electrified due to the constraints of the environment and investment costs. For electrified lines and non-electrified lines, only electric EMUs and pure internal combustion EMUs can be passed respectively. Therefore, EMUs need to be replaced during the journey to adapt to different forms of lines. [0003] In order to avoid the replacement of EMUs, in the prior art, dual power source EMUs are usually used. The dual power source EMUs integrate the internal combustion power system and the electric power system, and can run on electrified lines or non-electrified lines. Driving on the railway, so as to realize the conversion between the internal combustion power system and the electric power...
