Title:
SUPERCONDUCTING ELECTRIC POWER TRANSMISSION SYSTEM AND COOLING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/002200
Kind Code:
A1
Abstract:
In order to improve thermal insulation performance, for example, to enable the effective use of cold of LNG, a superconducting electric power transmission system configured to be provided with an inner tube (12) housing a superconducting cable (11) therein, a radiation shield (13) covering at least part of the inner tube (12) from outside, and an outer tube (14) housing the inner tube and the radiation shield therein, and maintain a vacuum from the inside of the outer tube (14) to the outside of the inner tube (12) with the radiation shield (13) therebetween is provided with a radiation shield tube (15) housed in the outer tube (14) and provided to be associated with the radiation shield (13), and passes, for example, liquid natural gas (LNG) as a second refrigerant for the radiation shield (13) through the radiation shield tube (15).
