Description

Technical Field

[0001] This utility model relates to the technical field of superconducting magnet testing equipment, and in particular to a quick-connect superconducting component testing Dewar. Background Technology

[0002] In existing technologies, the testing of components such as superconducting switches, current leads, and coils in superconducting magnets, as well as the calibration of thermometers, involves cumbersome procedures, including numerous wiring, disassembly, and reassembly steps. The cold shield of existing equipment typically relies on traditional cables to connect to external devices. Replacing test components requires disassembling the chamber and cold shield, removing solder joints, and reconnecting the new component, which is time-consuming and cannot achieve rapid plugging and unplugging, significantly reducing operational convenience and testing efficiency. Frequent disassembly and reassembly can easily lead to problems such as poor sealing and component misalignment, and can also cause temperature differences in different parts of the superconducting magnet, thus affecting its performance. Existing test Dewar chambers and cold shields are mostly fixed structures, unable to flexibly adapt to the testing needs of superconducting magnet components of different sizes. Superconducting magnets have wide applications in many fields, and the performance of their key components, such as superconducting switches, current leads, and coils, directly affects the overall performance of the superconducting magnet. Accurate testing of these components is necessary during production and maintenance, and accurate thermometer calibration is crucial for monitoring the temperature of the superconducting magnet's operating environment. Existing testing equipment suffers from problems such as complex structure and inconvenient operation, making it unable to efficiently complete the testing of important components of superconducting magnets and the calibration of thermometers.
