Problems solved by technology

[0004] In the prior art, cryogenic containers used for testing superconducting materials or devices and components cannot simultaneously provide test conditions such as variable temperature, variable pressure, low temperature and high voltage insulation, fault current impact, and the influence of gas-liquid relative insulation.

Since the individual tests of the above items cannot provide the change rule under the simultaneous action of multiple conditions, and cannot truly reflect the comprehensive characteristics of superconducting materials, superconducting devices or components under external conditions, it adds complexity to the research and development of superconducting power devices.
