The invention belongs to the technical field of diesel locomotive power supply, and particularly discloses a diesel locomotive passenger car direct power supply system with a composite power supply mode, which is formed by transforming an original DF4D type diesel locomotive power supply system and mainly comprises a main power supply system and an auxiliary power supply system, the main power supply system and the auxiliary power supply system jointly use a diesel engine of an original DF4D type diesel locomotive and are connected through a gear box. Wherein the main power supply system is mainly used for providing direct power supply for the passenger car; the auxiliary power supply system is mainly used for providing uninterrupted energy supplement for direct power supply of the passenger car when the main power supply system is intermittently powered off due to traction working condition conversion. The power supply system provided by the invention not only can provide uninterrupted direct power supply for the passenger car, but also can realize hot switching of three working conditions of locomotive traction, traction + power supply and independent power supply, and compared with the prior art, not only is the cost greatly saved, but also the experience feeling of crew members is obviously improved.

    本发明属于内燃机车供电技术领域,具体公开了一种复合供电方式的内燃机车客车直供电系统,所述供电系统是基于对原DF4D型内燃机车供电系统的改造而成,其主要由主供电系统和辅助供电系统构成,并且所述主供电系统与辅助供电系统共同使用原DF4D型内燃机车的柴油机,并通过齿轮箱连接;其中,所述主供电系统主要用于为客车提供直供电;所述辅助供电系统主要用于在主供电系统因牵引工况转换间歇断电时,为客车直供电提供不间断的能量补充。本发明所提供的供电系统,不但能够为客车提供不间断的直供电,而且可实现机车牵引、牵引+供电以及单独供电三种工况的热切换,相对现有技术不仅大幅节省了成本,还明显提升了乘务旅客的体验感。
