[0001] Technical field: [0002] The invention belongs to the technical field of application of high-temperature superconducting materials, and mainly relates to a high-precision torsion micro-clamp structure applicable to the application technology of high-temperature superconducting strips. [0003] Background technique: [0004] High-temperature superconducting materials refer to superconducting materials whose critical temperature is in the liquid nitrogen temperature region (77 K). Since Heike Kamerlingh Onnes (Kamerlingh Onnes) discovered that 4 K mercury has low-temperature superconducting properties in 1911, and Bernoz and Müller discovered the 35K superconducting lanthanum-barium-copper-oxygen system in 1986, superconducting materials have continued to development and breakthroughs. In 1987, Chinese-American Wu Maokun and others announced the discovery of the 90K yttrium-barium-copper-oxygen superconductor, which was the first breakthrough in the temperature barrier o...

AI Technical Summary

Problems solved by technology

The practical application of superconducting magnet devices requires the stable operation of internal high-temperature superconducting materials, but the actual working conditions are often more complicated, and many conditions such as low-temperature cooling, structural strength, and quench safe unloading need to be met. Although high-temperature superconducting material technology has made great strides development and progress (especially the successful research and development of high-temperature superconducting strips with use value), but its critical performance research technology under torsional complex torsional conditions is lagging behind
