Non-contact induction power supply system of magnetic levitation train

Abstract

The invention discloses a non-contact induction power supply system of a magnetic levitation train. The system comprises a ground system, a separating type transformer and a vehicle system. The groundsystem comprises a ground rectifier module and a high-frequency inversion module. The separating type transformer comprises a primary side compensation module, a transmitting coil, a receiving coil and a secondary side compensation circuit. The vehicle system comprises a vehicle rectifier module, a boosting module, a storage battery and a vehicle normal load. The system can supply power to the magnetic levitation train in a non-contact power supply manner when the magnetic levitation train operates at a low speed.

Description

technical field [0001] The present application relates to the technical field of rail transit, and more specifically, relates to a contactless induction power supply system for maglev trains. Background technique [0002] As we all know, medium and high-speed maglev trains must be driven by ground-powered long-stator linear motors due to their large traction power requirements. When the maglev train is running at high speed (speed greater than 100km / h), the energy obtained by the on-board linear generator from the long stator linear motor can meet the power demand of the maglev train, while when the maglev train is running at a low speed (speed is less than 100km / h), The energy obtained by the on-board linear generator from the long-stator linear motor cannot meet the power demand of the maglev train, and an external power supply method is required. [0003] At present, for maglev trains, the external power supply mode often used is contact power supply mode (eg, catenary r...

Problems solved by technology

[0005] However, in the contact rail power supply mode, since the vehicle-1 is in mechanical contact with the positive contact rail-6 and the negative contact rail-7, it will generate relatively large noise; moreover, the current-receiving equipment on the vehicle-1 is connected to the positive contact rail -6. If the negative contact rail-7 is mechanically contacted to obtain electricity, it will cause the wear and tear of the vehicle-1, resulting in a relatively large maintenance workload for the current-receiving equipment on the vehicle-1; in addition, the positive contact rail-6 and the negative contact rail -7 is easily affected by the environment (for example, in ice and snow weather, the positive contact rail-6 and the negative contact rail-7 are prone to ice / snow accumulation), resulting in poor power transmission, arcing by current, and endangering driving safety
