Document Type and Number:
Japanese Patent JPH0740783
Kind Code:
B2
Abstract:
PURPOSE:To firmly support and fix a superconductor and lighten the stress concentration on an insulator by forming the insulator in contact with the superconductor out of a composite insulator composed of an elastic member provided on the side of a contact face and a fiber-reinforced plastic core material for holding that elastic member, in a superconductive field winding. CONSTITUTION:For superconductive field winding 3, a winding structure 12 is formed by laminating superconductors 9 in plural rows through interrow insulators 7 and interlayer insulators 8, and it is accommodated in the groove 2 provided in the winding supporting ring 1 of a rotor, and it is insulated through an insulator 4 at the side face of the groove, an insulator 5 at the bottom of the groove, and an insulator 6 at the top of the groove. These insulators are of composite insulators, composed of elastic members provided on the face side in contact with the superconductor 9 and fiber reinforced plastic core materials for holding these elastic members. By doing it this way, the superconductor 9 is supported and fixed firmly during rotation and excitation, and besides the stress concentration on the insulator inside the winding is lightened, and it is electrically and mechanically stabilized.
