Abstract

A connection structure for connecting hollow formers (140) provided inside a superconducting cable (10), wherein the connection structure is characterized in that one end section and another end section of a hollow connecting conduit (145) are inserted into an open section (144) leading to a hollow interior section formed in a connection end section of each of the formers, the opposed connection end sections of the formers being welded together. The connection conduit (145) thereby ensures circulation of a refrigerant. Also, there is no incidence of the refrigerant circulation path being blocked when welding is performed in the connection conduit, allowing formers to be more easily connected.

Description

technical field

[0001] The present invention relates to a connection structure and connection method of a skeleton located at the center of a cable core of a superconducting cable. Background technique

[0002] The superconducting cable has a cable core and an insulating tube with a vacuum double-tube structure. The cable core has a skeleton and a superconducting wire. cycle.

[0003] Furthermore, in order to improve the cooling efficiency of the superconducting wire and the skeleton, the skeleton is formed in a hollow, and a liquid refrigerant circulates in the hollow.

[0004] However, in the case of using a superconducting cable as a power supply line, it is necessary to lay the superconducting cable from the power supply source to a remote power consumption place, and the superconducting cable is not a single piece due to manufacturing or transportation reasons. Cable length is limited. Therefore, when laying long-distance cables, it is necessary to connect several su...
