Title:
超電導ケーブル
Document Type and Number:
Japanese Patent JP4667644
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To transport hydrogen safely by using MgB2 superconducting wire not including oxygen element when a short-circuit accident, etc., occurs. SOLUTION: This superconducting cable is provided with a conductor which comprising a superconducting wire using MgB2 , and a cooling pipe which leads liquid hydrogen or cooled hydrogen gas maintaining a superconducting state. The conductor comprises a core and the superconducting wire is wound spirally on the core. An insulating layer is wound on the outside of the conductor. The superconducting wire is wound onto the insulating layer as required and the superconducting wire makes to flow a shield current in nearly reverse phase to the conductor. A plurality of stranded conductors are contained in the cooling pipe and the cooling pipe leads cooling liquid hydrogen. The layer of a heat insulating material is formed on the outside of the cooling pipe. A vacuum heat insulating tube is arranged on the outside of the layer of the heat insulating material. The tube has a space of which internal pressure can be maintained at an atmospheric pressure or less.
