Abstract

The present application relates to a magnetic coupling mechanism for rail transit wireless power supply. The magnetic coupling mechanism includes a transmitting power supply, a transmitting coil, a magnetic core, a receiving coil, a current adjustment circuit and an energy storage device. The magnetic core includes a base body. The first boss is arranged on the surface of the base body. The first guide rail and the second guide rail are arranged on both sides of the first boss. The first guide rail is electrically connected with the second guide rail to form a closed coil. In the magnetic coupling mechanism for rail transit wireless power supply, the receiving end of the magnetic coupling mechanism is arranged on the tram. In this application, the receiving end of the magnetic coupling mechanism adopts a rail-type receiving coil instead of a plate-type receiving coil. In the case of receiving the same magnetic flux, the metal volume of the rail-type receiving coil is smaller and the weight is lighter. The rail-type receiving coil reduces the weight of the receiving end of the vehicle-mounted magnetic coupling mechanism. Therefore, the magnetic coupling mechanism for rail transit wireless power supply reduces the load of the tram, realizes a lightweight design, and increases the overall performance of the tram.

Description

technical field [0001] The present application relates to the technical field of wireless power transmission, in particular to a magnetic coupling mechanism for rail transit wireless power supply. Background technique [0002] At present, the wireless charging of electric vehicles has been widely and maturely applied, mainly adopting the magnetic coupling wireless power transmission scheme. In the prior art, the magnetic coupling mechanism at the transmitting and receiving ends of the wireless power transmission structure adopts the form of a flat coil. The magnetic coupling mechanism at the receiving end is fixed on the vehicle body. [0003] Rail transit power supply needs more power, generally hundreds of kilowatts to several megawatts. The planar coil structure has larger volume and heavier weight. The weight of the planar coil structure increases the overall load on the vehicle and reduces the operational performance of the radio vehicle. Contents of the invention ...
