Description

technical field

[0001] The invention relates to the technical field of an online activation structure of an adsorption part of a heat-insulating cryogenic container, in particular to an online activation structure and an online activation method of an adsorption part of a superconducting cable insulation tube. Background technique

[0002] The superconducting cable insulation pipe is a double-layer pipe fitting, which includes an inner pipe and an outer pipe, and a vacuum interlayer is formed between the inner pipe and the outer pipe. The heat insulation performance of the superconducting cable heat insulation tube is determined by the vacuum degree of the vacuum interlayer. After the superconducting cable insulation tube is manufactured and vacuumized, due to factors such as the gas emitted from the material of the superconducting cable insulation tube itself, the vacuum degree will gradually decay with time, resulting in continuous degradation of the thermal insulation per...
