Power concentrated type internal combustion multiple unit train power supply system

Abstract

The invention discloses a power concentrated type internal combustion multiple unit train power supply system. The power concentrated type internal combustion multiple unit train power supply system comprises a main mission train and a reconnection train connected with the main mission train in a transmission mode; the main mission train is internally provided with a single-winding alternating current auxiliary electric generator, an auxiliary alternating current controller, a rectifier module and a power supply inverter for controlling power supply of the multiple unit trains; the alternatingcurrent auxiliary electric generator, the auxiliary alternating current controller and the power supply inverter are respectively connected with the rectifier module; the power supply inverter is connected with the auxiliary alternating current controller; the auxiliary alternating current controller is connected with a locomotive microcomputer control device; and the auxiliary alternating current controller connected with the locomotive microcomputer control device is arranged in the reconnection train. The power concentrated type internal combustion multiple unit train power supply system has the beneficial effects that compared with an independent diesel engine power supply set which needs to be termly maintained and needs the cost for replacing parts in the service lift of locomotiveoperation, the cost is more saved relatively through the alternating current auxiliary transmission system with train power supply under the premise of coequally meeting the power supply function of the trains.

Description

technical field [0001] The invention relates to the technical field of train power supply systems, in particular to a power centralized power supply system for internal combustion multiple trains. Background technique [0002] Domestic power centralized internal combustion EMUs use small diesel generator sets for train power supply, and the diesel engine speed is at least above 1650rpm or constant at 1800rpm. The AC auxiliary generator is used for train power supply, and its power supply is used as emergency fault power supply when the small diesel generator set fails. It belongs to emergency use under fault conditions, and cannot meet the traction performance and resistance braking performance of the EMU. High noise and poor economy. [0003] Another power supply scheme using double-winding AC auxiliary generators. When the train is powered, the diesel engine rotates at 1200rpm~1800rpm, and one set of windings sends out 320~480V three-phase alternating current to provide p...
