Three-component realization apparatus of train power supply device of train DC600V and realization method thereof

Abstract

The invention discloses a three-component realization apparatus of a train power supply device of a train DC600V and a realization method thereof. The realization apparatus comprises a first path main circuit, a second path main circuit, and a backup main circuit; and input terminals, output terminals and filter reactors of the first path main circuit and the second path main circuit are respectively connected with isolating switches. On the normal condition, the fixed two path main circuits supply power to a train and the third path main circuit is used for backup; when there is a fault at the first path main circuit or the second path main circuit, input / output switchover and reactor switchover are carried out through isolating switches; the whole inputs and outputs of the path with the fault are completely isolated and the backup main circuit is put into service. According to the invention, an updating demand on a train DC600V power supply device of a passenger electric locomotive in China can be met; and the demand that it can be ensured that there is always two path DC600V power supply outputs can also be met.

Description

technical field [0001] The invention relates to a railway vehicle power supply device, in particular to a three-component realization device and method for a train DC600V train power supply device. Background technique [0002] my country's railway passenger electric locomotives use DC600V main line power supply to provide power to each train car. In each train car, the air-conditioning inverter power converts DC600V into AC to drive the air-conditioning compressor to run to meet the air-conditioning requirements of the car. At present, 2 phase-controlled DC600V train supply devices are installed on my country's railway passenger electric locomotives, each of which supplies power to 1 / 2 of the train carriages. When 1 road fails, the temperature of the carriages will reduce the comfort of passengers. Especially in the hot summer and severe winter, the railway department has been complained by passengers. For this reason, according to the requirements of railway users, the mai...
