Title:
超電導導体
Document Type and Number:
Japanese Patent JP4135184
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To minimize heating loss by flowing most of the electric current to a superconductive layer in the rated operation and to minimize the heating by shunting the current to a metallic layer in the short circuit accident, by mounting the metallic layer for flowing the short circuit current to an outer periphery of a superconductive layer, to ensure a flowing path of the short circuit current. SOLUTION: A superconductive layer 2 formed by spirally winding a superconductive linear material on a former 1 as a core material, formed by a hollow metallic pipe made of aluminium alloy or the like to be used as a coolant path. This superconductive linear material is obtained by coating the ceramics superconductive material such as Y-Ba-Cu-O or the like by Ag or the like. A metallic pipe 3 such as a stainless tube or the like as a metallic layer is formed on the layer to obtain a superconductive conductor which can accept the short circuit current. This metallic layer can be formed by spirally winding a metallic tape. Further this metallic tape layers can be laminated through an insulating layer, or the superconductive layers and the metallic layers can be alternately laminated.
