Description

technical field [0001] The invention belongs to the field of superconducting cables, and relates to a testing device and method for temperature field and strain field in the running process of conduction cooling high-temperature superconducting cables. Background technique [0002] With the maturity of the high-temperature superconducting tape manufacturing process, the research on the use of high-current-carrying-density conduction-cooled high-temperature superconducting cables for power transmission has been further developed. Compared with conventional cables, conduction-cooled high-temperature superconducting cables have the advantages of large capacity, low loss, and small size. [0003] The advantage of adopting cryocooler conduction cooling to provide a low-temperature environment for the operation of the superconducting system is that it is simple in structure, easy to operate, and the volume and quality of the refrigeration system are greatly reduced. However, in t...
