Abstract

According to an elevated half-tube intelligent five-rail high-temperature superconducting maglev train system, a plurality of magnetic circuits of four electromagnetic rails of an elevated half-tube intelligent five-rail subsystem are linearly arranged and connected with a plurality of single coils in series in the same direction, and the four electromagnetic rails generate a continuous and uniform magnetic field in the rail direction; pinning magnetic fluxes generated by high-temperature superconducting blocks in 12 monitoring type intelligent Dewar are correspondingly arranged on the four electromagnetic rails in the half tubes respectively, the four electromagnetic rails are surrounded, and the acting force of automatic suspension, automatic stabilization and automatic guiding of the maglev train is enhanced; a plurality of section converters supply power under the control of a photoelectric proximity switch and a wireless remote control receiving module, the electromagnetic field intensity of the electromagnetic rails and the middle electromagnetic rail in the four sections can be controlled, the electromagnetic field can be turned off, and the four electromagnetic rails and the middle electromagnetic rail outside the sections are all in a power-off state; the electromagnetic rails in the interval generate a moving magnetic field to drive a linear direct-current permanent magnet motor rotor; and a linear alternating current generator rotor synchronously induces alternating current output.

Description

Technical field [0001] The present invention relates to a high-temperature superconducting magnetic suspension train, which is exactly a high-temperature superconducting magnetic suspension train system with a high-end half-tube intelligent five-track high temperature. Background technique [0002] At present, there is a high-temperature supercodent magnetic suspension train in my country is still in the experimental stage. The high-temperature superconducting magnetic suspension train is a maglev train based on the magnetic flux pinning between the high temperature superconductors and the permanent magnet track. The train does not need precise active control. It can be stably suspended to the track, realizing the automatic suspension, automatic stability and automatic orientation of the train, not only the magnetic suspension is stable, but there is no magnetoresistance, in addition to air resistance, there is no resistance, Train speed can be increased to 600 km / h, and the en...

Problems solved by technology

At present, the experimental systems of these two high-temperature superconducting maglev trains in my country currently use permanent magnet tracks built with permanent magnets. The disadvantage of permanent magnet tracks is that the magnetic field distribution generated by permanent magnet tracks is limited by the magnetization of a unit permanent magnet. Strength and magnetization direction, lack of variability; once the track is laid, its magnetic field strength cannot be adjusted; the magnetic field strength of the track will have a certain degree of attenuation over time; the magnetic field of the permanent magnet track cannot be turned off, and the permanent magnet The track will cause a certain degree of magnetic pollution; the construction cost of the full permanent magnetic track is high, and the construction cost of the full vacuum pipeline is even higher

In addition, the existing superconducting magnet cryogenic cooling device for high-temperature superconducting maglev trains still has problems such as complex structure, poor overload resistance, and how to keep the high-temperature superconductor in the Dewar at a low temperature for a long time; for example: the application number is "2021106468918" , the name is the application document of "Superconducting Magnet Cryogenic System for High-Temperature Superconducting Maglev Train"
