Problems solved by technology

Therefore, in the existing high-speed maglev trains, long-stator linear traction motors are used as power. At low speeds, current rails or capacitors or batteries are used to supply power to on-board equipment. At high speeds, capacitors + linear generators are used to power on-board equipment. A complete set of equipment leads to the defects of existing maglev vehicles with many equipments, heavy weight and tight space for vehicle installation

Abstract

The embodiment of the invention relates to the technical field of railway vehicles, and particularly relates to a maglev vehicle and a power supply device and a transmitting module thereof. The powersupply device comprises at least one receiving module. The receiving module comprises a current collecting plate and a power supply box, wherein the current collecting plate is used for generating induced electromotive force through magnetic coupling induction; and the power supply box is electrically connected with the current collecting plate and is used for rectifying and outputting the inducedelectromotive force generated by the current collecting plate. The receiving module of the power supply device generates the induced electromotive force through magnetic coupling induction, so that non-contact power supply of the maglev vehicle is achieved, contact type power supply equipment does not need to be installed, and the power supply device has the advantages that equipment is few, theweight is reduced, the vehicle installation space is saved, the friction is eliminated, the noise in the vehicle is reduced, the maintenance workload of a power supply system is reduced, and the reliability of the power supply system is improved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, to a maglev vehicle, a power supply device and a launching module thereof. Background technique [0002] Rail vehicles need power supply in the process of operation, control and maintenance, and an effective and reliable power supply and current receiving system is very critical to the vehicle. The power supply of existing maglev vehicles mainly includes the following four methods: current receiving rail, on-board capacitor, linear generator, and high-energy battery. The vehicle provides power. Linear traction motors are divided into short-stator linear motors and long-stator linear motors; short-stator linear traction motors require vehicles to provide power because the primary part and frequency converter are installed on the train, and the mass of the train will increase with the increase of speed. And limited by the length of the vehicle, it is only suitab...
