Problems solved by technology

The structure of the superconducting cable is relatively complex, and the components such as the cable core and the cooling medium circuit are very fragile.
When using the current various processes to connect cables, it is not only necessary to add additional structures to connect the cable core and other external parts separately, but also may damage fragile structures such as the cable core or the cooling medium circuit due to inadvertent operations during construction

Abstract

The invention relates to a modular assembly type superconducting cable cold sleeve structure. The modular assembly type superconducting cable cold sleeve structure comprises a superconducting cable core, an insulating layer, an upper cold sleeve, a lower cold sleeve, a cooling medium, a vacuum layer and a thermal insulation layer, wherein the upper cold sleeve and the lower cold sleeve are provided with vertically connected buckles to achieve the rapid assembly of the superconducting cable cold sleeve structure; at the same time, the two ends of the upper cold sleeve and lower cold sleeve areprovided with a cooling medium inlet and a cooling medium outlet which can be rapidly connected. The superconducting cable cold sleeve structure has the advantages of modularization, convenient assembly and convenient disassembly.

Description

technical field [0001] The invention is a modularized assembling type superconducting cable cold sleeve structure. Background technique [0002] In order to achieve high efficiency and low loss output, high temperature superconducting cables use non-resistance superconducting materials as conductors. Superconducting cables can transmit large currents, and also have the advantages of small size and light weight. [0003] High-temperature superconducting cables have a transmission loss of only 0.5%, which is much smaller than that of conventional cables. Compared with conventional power cables, high-temperature superconducting cables have a greater current density, while losses can be reduced by 60%. Using high temperature superconducting cables to transform the existing underground cable system can not only increase the transmission capacity by more than 3 times, but also reduce the total cost by 20%. Through the application of high-temperature superconducting cables, the ...
