Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a high-temperature resistant superconducting cable and a cable connection structure thereof. Background Art

[0002] Superconducting cable, also known as superconducting cable, is a power transmission medium designed and manufactured based on the property of superconducting materials with zero resistance under specific low temperature conditions. The working principle of superconducting cable is based on the zero resistance property of superconducting materials. When the superconducting material is in a superconducting state, the current can flow freely inside without encountering resistance, thereby realizing power transmission without energy loss.

[0003] For example, a Chinese patent with publication number CN219349865U discloses a superconducting wire core and cable, including a conductive substrate and a metal frame embedded in the conductive substrate, wherein the metal frame includes a plurality of frame units spaced apart along the axial direction of the superconducting wire core, each of the frame units is arranged parallel to the cross-section of the conductive substrate, and the plurality of frame units are connected by a plurality of support bars arranged along the axial direction.

[0004] The above-mentioned public patent improves the curvature of the superconducting wire core and improves the mechanical strength of the superconducting wire core, but the existing superconducting cables still have some defects that need to be improved. Although the superconductor in the superconductor cable adopts high-temperature superconducting material, this material does improve the high temperature resistance of the cable to a certain extent, but its high temperature resistance threshold is still limited, and it is difficult to maintain good conductivity and structural stability in extreme high temperature environments. This undoubtedly limits the application potential of superconducting cables in a wider range of scenarios. In addition, the connection method between the superconducting cable and the equipment, that is, connection through the terminal, also exposes some problems. During the installation process, the staff needs to accurately insert the cable core into the terminal and rely on multiple bolts to fix it. This bolt fixing method is not only cumbersome to operate, but also requires additional carrying and use of tools. In addition, the installation efficiency is relatively low, and it is difficult to achieve quick and convenient deployment. More importantly, when the cable is connected to the terminal, due to the lack of an intuitive feedback mechanism, it is often difficult for the staff to immediately judge whether the connection is stable and reliable, which undoubtedly increases the uncertainty and risk during the installation process.
