Abstract

The invention discloses an auxiliary alternating current system for an internal combustion motor train unit. The auxiliary alternating current system comprises an auxiliary generator set, a direct current circuit and more than one inverter circuit. The auxiliary generator set supplies power to a cooling fan and a traction ventilator of a corresponding internal combustion motor train unit through the inverter circuit. The auxiliary generator set supplies power to a direct connection load of the corresponding internal combustion motor train unit through the direct current circuit. The auxiliary alternating current system further comprises a train power supply generator set, a first switch module and a second switch module. The train power supply generator set respectively supplies power to an air compressor, a driver air-conditioner, an electric storage unit and a direct current load of the internal combustion motor train unit through the first switch module; the auxiliary generator set respectively supplies power to the air compressor, the driver air-conditioner, the electric storage unit and the direct current load of the internal combustion motor train unit through the second switch module; and the first switch module and the second switch module are in interlocking. The auxiliary alternating current system has the advantages of being simple in structure and high in reliability.

Description

technical field [0001] The invention mainly relates to the technical field of diesel locomotives, in particular to an auxiliary communication system for an internal combustion EMU. Background technique [0002] At present, the auxiliary transmission systems of traditional AC-DC electric drive diesel locomotives in China, such as DF4, DF5, DF7, DF8B, DF11, etc., are almost all driven by mechanical transmission, hydraulic transmission and DC motor drive. With the advancement and development of technology, especially the wide application of IGBT technology, the auxiliary transmission system of diesel locomotives adopts AC load system, such as NJ2 of Qinghai-Tibet Line, HXN5 of Qishuyan and HXN3 of Dalian. NJ2, HXN5 and HXN3 all use main and auxiliary integrated generators. The auxiliary generators are output by multiple sets of windings according to different voltage levels. HXN5 and HXN3 are mainly freight locomotives, and the auxiliary AC system does not consider redundancy....
