Title:
SUPERCONDUCTIVE COIL DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/172276
Kind Code:
A1
Abstract:
A superconductive coil device according to this disclosure comprises: a superconductive tape material wound in a helical shape over a plurality of layers; and a metal sheet and an insulating sheet that are provided between the layers of the superconductive tape material. The superconductive coil device is characterized in that the superconductive tape material and the metal sheet are electrically connected, and that the superconductive tape material is fastened with an adhesive between turns of one layer. With this superconductive coil device, prevention of burn damage occurring during quenching, prevention of characteristic degradation caused by hoop stress and axial compressive stress, and prevention of characteristic degradation caused by thermal stress during cooling can be accomplished simultaneously.
