Abstract

The invention provides a power supply system for an urban transportation vehicle, which comprises a base station power supply unit, an electric energy transmission unit and a vehicle-mounted power transformation unit, wherein the base station power supply unit comprises a high-frequency inverter and a power supply type convertor; an input end of the high-frequency inverter inputs direct current; an output end of the high-frequency inverter is connected with an input end of the power supply type convertor; the power supply type convertor is used for converting a constant voltage source output by the high-frequency inverter into a constant current source; the electric energy transmission unit comprises a ring transmission cable and an electric energy receiver; the ring transmission cable is buried along a road and connected with an output end of the power supply type convertor to form a high-frequency magnetic field; the electric energy receiver is arranged at the lower part of the vehicle to induct induction current generated by the high-frequency magnetic field; the vehicle-mounted power transformation unit comprises a vehicle-mounted current transformer; an input end of the vehicle-mounted current transformer is connected with the electric energy receiver; and an output end of the vehicle-mounted current transformer is connected with a drive motor of the vehicle.

Description

technical field [0001] The invention relates to electric power technology, in particular to a power supply system for urban traffic vehicles. Background technique [0002] At present, railway vehicles (such as EMUs, electric locomotives, and urban rail vehicles, etc.) supply power to railway vehicles through the catenary or the third rail. To build supporting infrastructure, such as catenary and its support poles. [0003] In the urban transportation system, such as the practical application of urban rail vehicles and urban electric bus vehicles, it is necessary to set up power grids and other infrastructures. Since the contact grids and infrastructures are set in the outer space of the city, they not only occupy urban space, but also affect the beauty of the urban environment. , and the existing catenary construction has high access costs and poor security. Contents of the invention [0004] The invention provides a power supply system for urban traffic vehicles, which ...
