The invention discloses a tramcar non-contact power supply and contact power supply coexisting power supply system which specifically comprises a non-contact power supply area, a contact power supplyarea and a non-power area. A train used in the power supply system is a double-current train; in the contact power supply area, electric energy is transmitted to a contact network through a traction substation, and a train pantograph receives current, and the electric energy is supplied to a traction motor through a traction converter and returns to a negative electrode of the traction substationthrough a steel rail and a return wire; and in the non-contact power supply area, electric energy is transmitted to an electric energy conversion device through the traction substation, the electric energy conversion device inverts direct current into high-frequency alternating current, the high-frequency alternating current is transmitted through a resonance compensation device and a transmittingcoil, the high-frequency alternating current is induced on a train pickup coil, and the electric energy is supplied to the traction motor through the other resonance compensation device, a rectifyingand filtering device, a DC-DC converter and the inversion device. The system has the advantages of convenience, flexibility, safety, environmental friendliness and the like, and meanwhile, the manufacturing and maintenance cost can be reduced.

    本发明公开了一种有轨电车非接触供电和接触供电共存的供电系统,具体包括非接触供电区域、接触供电区域和无电区域,该供电系统中所用列车为双流制列车;在接触供电区域,电能经牵引变电所传送至接触网上,列车受电弓受流,经牵引变流器给牵引电机供电,再经钢轨和回流线回到牵引变电所负极;在非接触供电区域,电能经牵引变电所传送至电能变换装置,电能变换装置将直流电逆变为高频交流电,经谐振补偿装置和发射线圈发射,列车拾取线圈上感应出高频交流电,通过另一个谐振补偿装置、整流滤波装置、DC‑DC变换器和逆变装置为牵引电机供电。本发明具有便捷、灵活、安全及环境友好等优点,同时能降低制造和维护成本。
