Problems solved by technology

[0013] The present invention aims to solve the problems of the existing superconducting cables, and provides a superconducting cable and a triaxial superconducting cable in which superconductors having each phase are stacked coaxially to form a core, and the outer cryostat portion is electrically conductive A high-resistance aluminum tube is constructed to serve as a neutral wire for a fault current to pass through a circuit without forming a neutral wire on the outer periphery of the core, thereby enabling superconducting cables to be manufactured at low production costs due to their small diameter and simple structure, and The reliability of the cable is also improved by preventing the electromagnetic forces generated at the neutral wire from overheating or damaging the insulation

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0035] figure 2 and image 3 The structure of a triaxial superconducting cable according to the present invention is shown.

[0036] refer to figure 2 and image 3, the triaxial superconducting cable 100 according to the present invention is configured to have a core 120 (hereinafter also referred to as “core portion”) in which superconductors having each electric phase are stacked coaxially in the cryostat portion 110 . exist figure 2 In , the center of the core 120 is offset from the center of the cryostat 110 (falling down), but the figure shows a cross-sectional view of an extended cable at an arbitrary point, and just fully expresses the core 120 falling due to gravity ( positioned at that point). Depending on the installation method or the curve of the cable, the core 120 may sag in the cryostat 110 or float in the middle at another...

Abstract

A superconducting cable is provided. The superconducting cable includes a core part including a former disposed at the center of the core part, one or more superconducting conductive layers with each electric phase disposed at the outside of the former in a radial directions, a insulating layer disposed at the outside of each the conductive layer in a radial direction and a shielding layer disposed at the outermost of the insulating layer; and a cryostat disposed at the outside of the core part in a radial direction with first space being interposed therebetween, having a vacuum part disposed therein and electrically wired to neutral pole (N pole).

Description

technical field [0001] The present invention relates to a superconducting cable, and more particularly to a superconducting cable in which superconductors having each phase are coaxially arranged in three layers to be configured as a core, and an outer cryostat portion having a high conductivity The aluminum tube is constructed to serve as the neutral wire. Background technique [0002] Compared with ordinary standard conduction cables, superconducting cables can transmit a large amount of electric power by using superconducting wires as conductors. [0003] For example, Korean Patent No. 10-2011-0091929 discloses a superconducting cable which may be a single-phase superconducting cable having a single core, or one in which multiple cores each having a different electrical phase are combined into a single body multiphase superconducting cable or the like, and the multiphase superconducting cable specifically includes a three-phase (A-B-C phase or R-S-T phase) superconductin...
