Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings: the present invention does not limit the size, shape and material of the ferromagnetic material implemented, and can be implemented in superconducting bulk materials of any material.

[0020] The present invention hereby provides a high-temperature superconducting maglev system that introduces ferromagnetic substances, including a rail 101 made of permanent magnets and magnetic gathering materials, and a cryogenic container 102 fixed in the frame of the car body. The high temperature superconducting bulk material layer 103 made of conducting bulk material. The permanent magnet track 101 is required to be a multi-stage permanent magnet track, and there are obvious vertical magnetic field and horizontal magnetic field peaks. A ferromagnetic substance 104 with high magnetic permeability is added to the superconducting bulk material corresponding to the horizontal magnetic...

Abstract

The invention discloses a high-temperature superconductive magnetic levitation system introduced with ferromagnetic substances. The system is characterized by comprising rails and a low-temperature container, the rails comprise permanent magnets, magnetic accumulation materials and the like, the low-temperature container is fixed into a vehicle body frame, a high-temperature superconducting bulk layer composed of superconducting bulks is fixed in the low-temperature container, and the ferromagnetic substances are arranged on the superconducting bulks corresponding to a horizontal magnetic field dominant area in the high-temperature superconducting bulk layer. The ferromagnetic substances are introduced above vehicle-mounted high-temperature superconductors, so that stable levitation performance of an original high-temperature superconductive magnetic levitation system can be remarkably enhanced, the high-temperature superconductive magnetic levitation system introduced with the ferromagnetic substances is simple in structure, easy to process, convenient to popularize and the like and can be suitable for places with higher requirements on guide performance of a high-temperature superconductive magnetic levitation vehicle in practical application, such as occasions in curve operation.

Description

technical field [0001] The invention relates to the technical field of high-temperature superconducting maglev, in particular to a high-temperature superconducting maglev system introducing ferromagnetic substances. Background technique [0002] High-temperature superconducting magnetic levitation technology, due to the unique magnetic flux pinning characteristics of high-temperature superconductors, has the advantage of self-sustaining and stable suspension, and has shown good application prospects in frictionless bearings, flywheel energy storage, rail transportation and other fields. Among them, the birth of the world's first manned high-temperature superconducting magnetic levitation test vehicle in my country in 2000 demonstrated the great attraction of high-temperature superconducting magnetic levitation technology in future new (high-speed, environmentally friendly, comfortable, etc.) rail vehicles, which aroused the international community's attention. extensive atten...
