Title:
END STRUCTURE OF SUPERCONDUCTING CABLE
Document Type and Number:
WIPO Patent Application WO/2006/087761
Kind Code:
A1
Abstract:
An end structure for a superconducting cable, in which deterioration of airtightness performance of a seal provided at the boundary between the normal temperature side and the cryogenic temperature side can be suppressed for use over a long period. The end structure has an end of a superconducting cable (100), a bushing (10) for electric conduction of a superconductive body (100a) of the cable (100), and a refrigerant container (11) for receiving the end and the bushing (10). In the refrigerant container (11), a liquid nitrogen layer (13) on the cryogenic temperature side and a nitrogen gas layer (14) on the normal temperature side are arranged next to each other. In the nitrogen gas layer (14), the distance t between the inner surface (11a) of the refrigerant container (11) and the outer periphery of the bushing (10) is set to a magnitude at which the nitrogen gas is kept in a gaseous state without pressurization by a pressurizing machine and at which the pressure of the nitrogen gas and the pressure of the liquid nitrogen are in equilibrium.
