Description

Technical Field

[0001] This invention relates to the field of high-temperature superconducting magnet technology, and more specifically, to a condition assessment method and system for conductive-cooled high-temperature superconducting magnets. Background Technology

[0002] Conductive-cooled high-temperature superconducting magnets are high-temperature superconducting magnets that utilize conductive cooling technology. Unlike traditional immersion cooling methods, conductive cooling directly cools the superconducting magnet using a cryogenic compressor, thus avoiding the complexity and high cost associated with using cryogenic fluids. The structure of a conductive-cooled high-temperature superconducting magnet typically includes a refrigerant, compressor, vacuum container, radiation shield, copper and high-temperature superconductor composite leads, the high-temperature superconducting magnet itself, magnet protection circuitry, and power supply. The cooling structure inside the vacuum container is in direct contact with the magnet, removing heat generated during operation through thermal conduction. Cooling plates are installed on both sides of each coil unit to enhance the cooling effect.

[0003] However, existing technologies typically only use a single indicator to judge and evaluate conductive-cooled high-temperature superconducting magnets, without providing a comprehensive and multi-faceted method and system for judging and evaluating conductive-cooled high-temperature superconducting magnets. This makes the evaluation of conductive-cooled high-temperature superconducting magnets inaccurate and impractical.

[0004] Therefore, there is an urgent need for a state assessment method and system for conductive cooling high-temperature superconducting magnets to solve the problems existing in the prior art. Summary of the Invention

The electrical condition assessment value X of the conductive cooling high-temperature superconducting magnet is determined based on the voltage difference ΔU. The real-time temperature value Ws is compared with the initial working temperature value Wc to obtain the temperature difference value ΔW, ΔW=Wc-Ws. The cooling state evaluation value Y of the conductive cooling high-temperature superconducting magnet is determined based on the temperature difference value ΔW.
