Abstract

The invention provides a tripolar magnetic coupling mechanism applied in a rail traffic wireless power supply system. The tripolar magnetic coupling mechanism is composed of a power supply guide railfor emitting electric energy and an electric energy receiving device for receiving the electric energy. Compared with existing magnetic coupling mechanisms, the tripolar magnetic coupling mechanism has the advantages that little electromagnetic radiation is generated, electromagnetic compatibility is high, eddy loss of a leakage magnetic field in a rail in actual application is low, system efficiency is improved, and no radiation damage is caused to working personnel around the rail.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, in particular to a three-pole magnetic coupling mechanism applied to a rail transit wireless power supply system. Background technique [0002] With the successful promotion of high-speed rail in the world, high-speed or even ultra-high-speed trains have become the focus of future rail transit research. At present, rail trains mostly use the pantograph to obtain electricity from the catenary grid. With the increase of train speed, the friction between the pantograph and the catenary grid increases rapidly, which not only increases the mechanical friction loss, but also makes the The pantograph produces strong vibrations, which increases the off-line rate, thereby significantly reducing the quality of the flow and affecting the normal running of the train. Therefore, the way of wired power supply limits the development of rail transit to high speed. [0003] Compared with the...
