Abstract
Official abstract text for this publication.
A connection structure for superconducting cables includes: superconducting cables that are connected to each other and include cable cores containing formers and superconducting conductor layers, and each cable core is housed in a thermal insulation tube with a cooling medium, wherein the cable cores include electric insulating layers obtained by winding insulating sheets around the superconducting conductor layers, the electric insulating layers on both sides of a conductor connecting part, in which the formers and the superconducting conductor layers are connected to each other, include taper shape portions each having a diameter reducing towards the conductor connecting part, each taper shape portion is formed so as to have an inclination angle changing in a stepwise fashion by a plurality of tapered portions among which a tapered portion nearer the conductor connecting part has smaller inclination angle, and a reinforcing insulating layer is provided between the taper shape portions.
First claim

The invention claimed is: 1. A connection structure for superconducting cables comprising: superconducting cables that are connected to each other and include cable cores containing formers and superconducting conductor layers, respectively, and each of the cable cores is housed in a thermal insulation tube with a cooling medium, wherein the cable cores include electric insulating layers obtained by winding insulating sheets around the superconducting conductor layers, respectively, the electric insulating layers on both sides of a conductor connecting part, in which the formers and the superconducting conductor layers are connected to each other, include taper shape portions each having a diameter reducing towards the conductor connecting part, each of the taper shape portions is formed so as to have an inclination angle changing in a stepwise fashion by a plurality of tapered portions among which a tapered portion nearer the conductor connecting part has smaller inclination angle, and a reinforcing insulating layer is provided between the taper shape portions, wherein when a tapered portion nearest the conductor connecting part among the tapered portions of the taper shape portion is defined as a first one, inclination angles α 1 to α n of the tapered portions from first one to n th one fulfill a condition of the following formula, [ Formula 8 ] [ FIRST STEP ] A · sin α 1 y < 1 ( r ≦ y < Y 1 ) , y = r + x · tan α 1 ( 0 ≦ x < X 1 ) ( 7 ) [ SECOND STEP ] A · sin α 2 y <
