Problems solved by technology

[0004] In addition to high-temperature superconducting coil magnets that can be used for the propulsion of maglev vehicles, the application of high-temperature superconducting block magnets in linear motors can also be used as the secondary of linear motors. There are unilateral and bilateral structures, but generally Combined with the conventional slide rail device to control the distance between the primary and secondary of the motor, the friction loss caused by the interaction between the slider or the pulley and the slide rail is inevitable
[0005] Also do not have a kind of efficient maglev propulsion system that can avoid above-mentioned defect at present
Moreover, there is no convenient and effective technical solution for on-orbit magnetization of alternating magnetic poles for high-temperature block magnet arrays for linear motors.

Abstract

The invention discloses a high-temperature superconductive magnetic suspension linear propulsion system with composite ontrack magnetizing function. A bilateral-type high-temperature superconductive linear synchronous motor with a high-temperature superconductor magnet array used as a secondary is used for realizing propulsion, a high-temperature superconductive magnetic suspension subsystem can be used for realizing stable suspension; a secondary active cell of the bilateral-type high-temperature superconductive linear synchronous motor and a suspension active cell of the high-temperature superconductive magnetic suspension subsystem are connected into a whole, thus stable suspension propulsion can be realized in a static or a moving state. The system combines a split pulse coil ontrack magnetizing device which is arranged on a bilateral primary stator of the linear electric motor so as to easily obtain the alternative-polarity high-temperature superconductor magnet array, thus the key technical problem of the magnetizing of the alternative-polarity high-temperature superconductor magnet array can be solved effectively..

Description

technical field [0001] The invention belongs to the application field of high-temperature superconducting technology, in particular to a high-temperature superconducting maglev vehicle, such as a maglev train. Background technique [0002] At present, there are two main forms of application of high-temperature superconducting materials in maglev vehicles. One is to use high-temperature superconducting coil magnets to generate strong magnetic fields and place them on movers or train bodies. The closed coil cuts the strong magnetic field generated by the high-temperature coil magnet, and generates a magnetic field opposite to it. The two magnetic fields interact to generate a repulsive force. When the moving speed of the train exceeds a certain value, the repulsive force will be greater than the gravity of the train to achieve suspension; at the same time, the The high-temperature superconducting coil magnet is used as the secondary of the linear motor to realize the propulsio...
