NON-CONTACT TYPE POWER COLLECTING DEVICE FOR MAGNETICALLY LEVITATED VEHICLE TYPE RAILWAY TRANSPORTATION SYSTEM

摘要

ABSTRACT OF THE DISCLOSUREIn a magnetically levitated train, a non-contact type power collecting device utilizing theharmonics of reaction magnetic flux generated fromlevitation ground coils is provided for supplyingrequired power to air-conditioning equipment, lightingequipment, etc. in the train. In such a device, aplurality of power-collecting induction coils aredisposed on the train body opposite to the levitationground coils, and the voltage induced in the power-collecting induction coils by the harmonic componentsof reaction magnetic flux generated from the levita-tion ground coils is applied to a power converter tosupply required power to the air-conditioning equipment,lighting equipment, etc. According to the presentinvention, the individual power-collecting inductioncoils have different numbers of turns depending onthe level of the voltage induced due to interlinkage ofthe space harmonics from the levitation ground coilswith the power-collecting induction coils thereby tobalance the weights of the individual power-collectinginduction coils with their power collecting capabilities,so that power can be efficiently collected to beeffectively supplied to the loads.
