Title:
Connection structure and a connection method of a former of a superconductivity cable
Document Type and Number:
Japanese Patent JP6062378
Kind Code:
B2
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 cooling medium circulation path being blocked when welding is performed in the connection conduit, allowing formers to be more easily connected.
