Problems solved by technology

However, this independent high-temperature superconducting refrigeration has the following defects: since the refrigeration system usually occupies a certain space and has a minimum volume limit, the independent refrigeration system requires a relatively large space and a large volume, and the space utilization rate is not good. High defects, and there is a problem that the volume of the entire system cannot be actually reduced; at the same time, there is also the problem of inconvenient magnetization operation, and the problem of the characteristic difference of high-temperature superconductors caused by temperature differences

Abstract

The invention discloses a high-temperature superconducting linear suspension propulsion system, which comprises a high-temperature superconducting magnetic suspension system and a high-temperature superconducting linear propulsion system which share the same cryostat to form a composite integrated rotor, wherein only one cryostat is arranged in the high-temperature superconducting linear suspension propulsion system. Compared with the prior art, the invention has the advantages that: the high-temperature superconducting magnetic suspension system and the high-temperature superconducting linear propulsion system share a set of refrigerating system to form a composite integrated rotor structure, so that the magnetic suspension system and the propulsion system are combined into a whole, the characteristics of a high temperature superconductor are fully utilized, and space limitation and limitation of minimum volume brought by the refrigerating system are avoided; moreover, the problem of characteristic difference of the high temperature superconductor due to temperature difference is solved in the independent refrigerating process, so that the high-temperature superconducting linear suspension propulsion system is lower in loss, smaller in volume, lighter in weight, higher in efficiency and easier to operate.

Description

technical field [0001] The invention belongs to the technical field of superconductivity, and in particular relates to a linear suspension propulsion system using a high-temperature superconductor. Background technique [0002] At present, there have been researches on high-temperature superconducting maglev systems composed of high-temperature superconducting bulk materials and conventional permanent magnet rails, and have been applied to the development of maglev vehicles. This kind of magnetic levitation system has self-suspension and self-guiding functions, and can achieve stable levitation under static conditions, and simplifies the guidance control; It is still difficult to get rid of the shortcomings of the conventional linear motor itself. In particular, the conventional linear motor system used for propulsion cannot be effectively integrated with the high-temperature superconductor, which is not conducive to the miniaturization of the mover, and it is also inconven...
