Abstract

The invention discloses a traction motor power supply system and an electric locomotive power supply device. The traction motor power supply system comprises an energy storage system, a contactor, aninverter and a disconnecting switch, the energy storage system is connected with a first end of the contactor and used for outputting direct current, a first end of the inverter is connected with a second end of the contactor, and a second end of the inverter is connected with the disconnecting switch and used for converting direct current generated by the energy storage system into alternating current and supplies power for a traction motor. The supply system supplies power for the traction motor of an electric locomotive in non-electric areas by the aid of the energy storage system and the inverter, so that the electric locomotive automatically and continuously passes the non-electric areas.

Description

technical field [0001] The invention relates to the field of energy storage, in particular to a traction motor power supply system and electric locomotive power supply equipment. Background technique [0002] In recent years, with the development of new energy technology, especially the development of power battery technology, electric locomotives such as energy storage trams have become more and more popular in the market. However, ordinary electric locomotives cannot supply power to the traction motors when passing through a depot without electricity, and the usual method is to use internal combustion shunting locomotives. However, the use of internal combustion shunting locomotives requires additional operation and deployment personnel, deployment plans and resources, resulting in low efficiency, high consumption, and large pollution from internal combustion engines, which does not conform to the development trend of high-efficiency production. [0003] Therefore, how to...
