The invention relates to the technical field of railway vehicles, in particular to a direct-current power supply circuit, control method and system for an internal combustion motor train unit, and the circuit comprises a direct-current power supply, a control unit, a switch unit and a plurality of direct-current loads with different power supply durations. The input end of each DC load is electrically connected with a contact of the output end of the switch unit, and the output end of the control unit is electrically connected with the input end of the switch unit; and in the power supply state of the direct-current power supply, the control unit controls the contact of the output end of the switch unit corresponding to the direct-current load reaching the power supply duration to be disconnected according to the power supply duration of each direct-current load. The invention aims to solve the problems that the capacity of a direct-current power supply in the prior art is limited, and an existing power supply circuit is always in a power supply state for a direct-current load, so that the power supply time of the direct-current power supply is short, and a worker cannot conveniently overhaul a vehicle for a long time.
本发明涉及轨道车辆技术领域,尤其涉及一种内燃动车组直流供电电路、控制方法及系统,其电路包括:直流电源、控制单元、开关单元和若干个不同供电时长的直流负载;每个所述直流负载的输入端与所述开关单元输出端的触点电连接,所述控制单元的输出端与所述开关单元的输入端电连接;所述直流电源供电状态下,控制单元根据每个所述直流负载的供电时长,以控制与达到供电时长的所述直流负载相对应的所述开关单元输出端的触点断开。本发明的目的是以解决现有技术中直流电源的容量有限,现有的供电电路一直对直流负载处于供电状态,使得直流电源的供电时长短,不便于工作人员长时间对车辆进行检修的问题。
