Abstract

The invention relates to the technical field of superconducting magnets, and discloses a high-temperature superconducting non-insulation magnet. The magnet comprises a vacuum protection shell and a plurality of superconducting coil groups arranged in the vacuum protection shell, wherein each superconducting coil group comprises a motor, a first switching device, a second switching device, a heat anchor, a refrigerating machine, a cold storage tank, a plurality of flux pumps, a plurality of non-insulation superconducting coils connected in series, a constant-current switch and a cold shield. Therefore, the heat radiation of the magnet can be reduced through the vacuum layer and the cold shield, the stability and robustness of a magnet system can be improved by adopting the non-insulation superconducting coils, and the reliability of refrigeration can be ensured through a mixed refrigeration mode that the refrigerator refrigerates the cold shield, the plurality of non-insulation superconducting coils and the refrigeration medium.

Description

technical field [0001] The invention relates to the technical field of superconducting magnets, in particular to a high-temperature superconducting non-insulated magnet. Background technique [0002] Because of the excellent electromagnetic and mechanical properties of high-temperature superconducting materials, and with the reduction of their manufacturing costs, research on high-temperature superconducting magnets based on high-temperature superconducting materials has become more and more extensive. At present, most applications of high-temperature superconducting magnets are concentrated on static magnets, such as medical MRI magnets and high-field magnets. However, when high-temperature superconducting magnets are applied to dynamic occasions, such as mover magnets of superconducting linear motors (such as the superconducting magnets onboard superconducting maglev trains on the Yamanashi Line in Japan, the superconducting maglev trains on the Yamanashi Line in Japan mai...
