MAGNETIC LEVITATION TRAIN AND TRACTION CONTROL METHOD THEREFOR

WIPO Patent Application WO/2020/077688

A1

A magnetic levitation train and a traction control method therefor. The magnetic levitation train comprises: a levitation system and a traction system; two external power source control switches (KM01) respectively provided in vehicles (MC1, MC2) at two ends of the train, wherein the external power source control switches (KM01) are used for controlling whether an external power source is connected to the traction system for power supply; a storage battery pack used as a power source of the levitation system and as a backup power source of the traction system; and a backup power source conversion switch (KM02) used for controlling whether the storage battery pack is connected to the traction system for power supply. The traction control method comprises the following steps of: when a preset power supplying condition of a backup power source is reached, controlling the two external power source control switches (KM01) to be opened and the backup power source conversion switch (KM02) to be closed. The technical solution solves the technical problem that the magnetic levitation train cannot operate when the related magnetic levitation train cannot obtain power from a third rail and a reflux rail.
