The invention discloses a power supply device of a ground groove contact net segmented current supply tramcar. The power supply device comprises a cable groove, segmented contact net cables are arranged in the cable groove, and the power supply cables are connected with the contact net cables of all the segments through contactors of all the segments. The pantograph guides current into an electriccontrol box in the vehicle and is fixed at the bottom of the vehicle; the electric control box is a control center of a train, and signal input and output are achieved through a sensor and an instruction transmitting device which are arranged inside the electric control box. A wireless instruction transmitting device on the tramcar remotely controls the contactor of the segment, so that the contact net cable of the segment is electrified; meanwhile, the segment of contact net cable below the vehicle body is powered off, and the phenomenon that only one segment of the contact net cable in thewhole line is electrified is realized; the existing mature power transmission and transformation technology and the variable-frequency motor driving technology are fully utilized, so that the locomotive driving structure is simple, the vehicle-mounted weight is light, the construction, operation and maintenance costs are low, and as no secondary power supply exists, batteries, charging and other problems are not involved, the system is more energy-saving and environment-friendly.

    一种地槽触网分段授流有轨电车供电系统,供电装置包括电缆槽,电缆槽内设有分段的触网电缆,供电电缆通过各个段的接触器与各个段的触网电缆连接;授电弓将电流导入车内的电控箱中,授电弓固定在车的底部;电控箱是列车的控制中心,通过内部设的传感器和指令发射装置实现信号的输入和输出;电车上的无线指令发射装置遥控该段的接触器,从而使该段的触网电缆有电;同时使车身下方的这段触网电缆断电;实现了全线只有唯一的一段触网电缆带电,本发明充分利用现有成熟的输变电技术和变频电动机驱动技术,使机车驱动结构简单、车载轻、建造、运行和维护成本低,由于没有二次电源,不涉及电池和充电等问题,使该发明更加节能和环保。
