The invention relates to an engineering vehicle power supply system, in particular to a power supply system for a rail transit engineering vehicle. Comprising a converter cabinet, and an auxiliary device, an operation device, a life device, a high-voltage box, a diesel generator set, a first brake resistor, a second brake resistor, a high-voltage box, a first traction motor, a second traction motor, a third traction motor, a fourth traction motor and other devices which are connected with the converter cabinet. According to the whole structure, a traction transmission system with an AC1150V diesel generating set and a DC1500V pantograph serving as power sources is adopted, and the system structure is simple and reliable. The core content of the integrated multi-source auxiliary power supply output system is that power supply is converted through a main traction system, auxiliary power of four different power supply systems is output, main-auxiliary integration and multi-power supply system output integration are achieved, and the power utilization requirement that no auxiliary equipment and operation equipment are used on a vehicle is met; and power can be provided for other working vehicles.

    本发明涉及工程车供电系统,尤其涉及一种轨道交通工程车用供电系统。包括变流柜,以及与变流柜连接的辅助设备、作业设备、生活设备、高压箱、柴油发电机组、制动电阻一、制动电阻二、高压箱、牵引电机一、牵引电机二、牵引电机三、牵引电机四和其他设备,整体结构采用AC1150V柴油发电机组和DC1500V受电弓为动力源的牵引传动系统,系统结构简单可靠。一体化多源制辅助电源输出系统的核心内容为通过主牵引系统供电进行变换,输出4种不同电源制式的辅助用电,实现主辅一体化和多电源制式输出一体化,满足车上不用辅助设备和作业设备的用电需求,同时通过车上的大功率供电插座,可以为其他作业车提供动力。
