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 embodiments of the present application relate to the technical field of rail vehicles, and in particular, relate to a maglev vehicle, a power supply device and a launching module thereof. The power supply device includes at least one receiving module; the receiving module includes a current receiving plate and a power supply box, and the current receiving plate is used to generate induced electromotive force through magnetic coupling induction; the power supply box is electrically connected to the current receiving plate and used for The induced electromotive force generated by the current receiving plate is rectified and output. The receiving module of the power supply device generates induced electromotive force through magnetic coupling induction to realize the non-contact power supply of the maglev vehicle without installing contact power supply equipment. Reduce the maintenance workload of the power supply system and improve the reliability of the power supply system.

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...
