High-temperature superconducting magnet with magnetic ring

Abstract

The invention belongs to the technical field of superconducting magnets, and particularly relates to a high-temperature superconducting magnet with a magnetic ring. In the high-temperature superconducting magnet with the magnetic ring, by a first silicon steel concentrating flux plate and a second silicon steel concentrating flux plate, a radial component of a leakage magnetic field at the end part of a high-temperature superconducting winding can be reduced, and critical current at the end part of the high-temperature superconducting winding can be increased; according to the high-temperature superconducting magnet, the number of parallel high-temperature superconducting tapes is not required to be increased, so that the problem of high rate of non-uniform current distribution and loop current between the parallel high-temperature superconducting tapes is solved; the structure of the high-temperature superconducting winding is not changed or a high-temperature superconducting material is not replaced, and the high-temperature superconducting magnet is applicable to high-temperature superconducting windings of a cross-over coil structure and a solenoid structure.

Description

technical field [0001] The invention belongs to the technical field of superconducting magnets, in particular to a high-temperature superconducting magnet containing a magnetic ring. Background technique [0002] The high-temperature superconducting magnet is made of high-temperature superconducting tape, but the high-temperature superconducting tape has anisotropy, and the radial component of the leakage field at the end of the high-temperature superconducting magnet will greatly reduce the critical current of the high-temperature superconducting tape at this position. At present, there are two main measures to solve the influence of the end leakage field on the performance of high temperature superconducting magnets. [0003] The first method is to add parallel coils at the upper and lower ends of the high-temperature superconducting magnet. If the high-temperature superconducting magnet is spatially divided into upper, middle and lower sections, under normal circumstance...
