Abstract
The invention provides a tractive power supply system of an urban rail vehicle. An accumulator cell tractive button, a pantograph position button and a current collector position button are arranged on the urban rail vehicle. Three schemes of current collector current power supply, pantograph current power supply and accumulator cell power supply are integrated. The general urban rail vehicle uses a current collector for power supply during main track operation, uses pantograph for the power supply after entering a garage, and uses an accumulator cell for power supply after entering a nonelectric area because of the error operation of a driver. Therefore, the tractive power supply system provided by the invention can be switched to be at an appropriate power supply mode so as to improve the generality of vehicle use. Especially when the vehicle enters the nonelectric area, the urban rail vehicle can continuously travel under the mode of accumulator cell power supply without need of other rescue vehicles, and therefore, rescue tasks can be saved, and the occupancy time of the rescue vehicles on a main train operation track is reduced so as to improve the operation efficiency of the urban rail vehicle.
