Pneumatic high-temperature superconducting magnetic levitation rail vehicle system

Abstract

The invention discloses a pneumatic high-temperature superconducting magnetic levitation rail vehicle system. The pneumatic high-temperature superconducting magnetic levitation rail vehicle system comprises a remote controller, a permanent magnetic rail and a superconducting rail vehicle. The remote controller comprises a remote control box, a first pressing key, a second pressing key, a remote control battery and a signal emitting system. The permanent magnetic rail is made up of a circular rail fixed on a bracket. The superconducting rail vehicle comprises a vehicle type outer shell, and the front part of the vehicle type outer shell is internally provided with a vehicle body battery and a signal receiving system. The circular rail is evenly inlaid with permanent magnet bulks. The permanent magnet bulks are distributed in rows in the width direction of the circular rail and are distributed in columns in the length direction of the circular rail. An injecting hole is formed in the top of the vehicle type outer shell. A power system which adopts an air driving way is arranged at the tail of the vehicle type outer shell. A low-temperature vessel is arranged at the bottom of the vehicle type outer shell. The low-temperature vessel comprises a vessel room and an upward liquid nitrogen canned channel. High temperature superconducting bulks are evenly and symmetrically arranged in the vessel room. According to the pneumatic high-temperature superconducting magnetic levitation rail vehicle system, the manufacturing cost of the permanent magnetic rail is reduced, and the payload capacity of the superconducting rail vehicle is improved.

Problems solved by technology

Since the "long fixed piece" power system uses a linear motor wound on the guide rail as the driving part of the high-speed magnetic levitation column, the cost of making the guide rail is extremely expensive; the "short fixed piece" power system uses a linear induction motor wound on the passive track ( LIM) as a driving component, because the LIM is too heavy, the effective load capacity of the train is reduced. Although this system saves the production cost of the guide rail, it increases the operating cost of the train.
