Problems solved by technology

[0002] High-temperature superconducting magnets wound with second-generation high-temperature superconducting tape are difficult to operate in continuous current mode like low-temperature superconducting magnets due to their own material characteristics.
Because it is difficult to operate in continuous current mode, the more common magnetization scheme is to directly use DC power supply to supply power to the magnet for a long time
The problem of this scheme is: first, the superconducting magnet DC power supply equipment is expensive, and long-term operation produces wear and a lot of energy consumption; Due to its own resistance heating, it brings a greater burden to the refrigeration system

Abstract

The embodiment of the invention relates to the technical field of a superconducting magnet energy charging power supply, and particularly discloses a permanent magnetic type superconducting magnet wireless energy charging power supply. The permanent magnetic type superconducting magnet wireless energy charging power supply comprises a permanent magnet, a power mechanism for driving the permanent magnet to take the circular motion around a rotating shaft, a superconducting stator capable of being cut by a magnetic field of the permanent magnet, and a superconducting coil forming a superconducting closed loop with the superconducting stator; and both the superconducting stator and the superconducting coil are in a superconducting state. According to the permanent magnetic type superconducting magnet wireless energy charging power supply disclosed by the invention, based on a novel vortex dynamics magnetizing principle, non-contact type energy charging can be implemented on a superconducting magnet, and the superconducting magnet is helped to operate in a persistent current mode; the device greatly reduces superconducting magnet power supply cost and operation energy consumption; and meanwhile, a current lead is avoided and a load of a refrigeration system is reduced.

Description

technical field [0001] The invention relates to the technical field of a superconducting magnet charging power supply, in particular to a permanent magnet superconducting magnet wireless charging power supply. Background technique [0002] The high-temperature superconducting magnet wound by the second-generation high-temperature superconducting tape is difficult to operate in the continuous current mode like the low-temperature superconducting magnet due to its own material characteristics. This is mainly determined by two factors: first, at higher operating temperatures (such as the boiling point of liquid nitrogen at 77K), the creeping phenomenon of magnetic flux leads to obvious current attenuation, which is due to the relatively small n value in the E-J relationship of superconductivity. Second, it is very difficult to make a high-temperature superconducting DC switch with zero resistance, because the second-generation high-temperature superconducting strip is a coating...
