The wireless heating power module comprises a secondary coil, a heating component and a magnetic conduction sleeve, wherein the secondary coil is arranged inthe protruding cavity, the heating component is arranged in the absorption layer or outside the absorption layer and is connected with the secondary coil, the magnetic conduction sleeve is used for sleeving the protruding cavity, a primary coil is arranged in the magnetic conduction sleeve and is corresponding to the secondary coil, and the primary coil is connected with a power supply. With the adoption of a wireless connection mode, electrical heating of the heating component is achieved, the superconduction cable heat-isolation tube is not needed to be disassembled or broken, on-line simulation of the absorption piece can be achieved, the vacuum lifetime of the superconduction cable heat-isolation tube is prolonged, and the maintenance process is simplified.

Description

technical field [0001] The invention relates to the technical field of an adsorption component activation structure for a heat-insulated cryogenic container, in particular to a wireless heating power supply assembly and a wireless heating method for a heat-insulated tube of a superconducting cable. 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 performance.

Problems solved by technology

Using the existing method of using the adsorbent, the activated adsorbent cooperates with vacuum equipment to keep the vacuum degree of the superconducting cable insulation tube up to the requirements before use, although the adsorbent is still in use during the use of the superconducting cable insulation tube It can absorb a certain amount of gas, but the adsorption capacity of the adsorbent in the superconducting cable insulation tube will quickly reach saturation, the adsorption capacity will gradually decrease, and eventually fail, which leads to the short vacuum life of the conductive cable insulation tube
