METHOD AND APPARATUS FOR WINDING OF SUPERCONDUCTING PANCAKE COIL

摘要

PURPOSE:To obtain a winding method and a winding apparatus wherein a working strain which is exerted on a superconducting cable is small and a superconducting pancake coil whose performance is high and whose dimensional accuracy is high can be formed easily. CONSTITUTION:A superconducting cable 1 is set to a spiral shape which is not restrained; it is transferred to a fixation stand 14 from an electric-wire drum; the end of its outer circumferential side is fixed to the fixation stand 14 ; the end of its inner circumferential side is connected to a bobbin which is arranged at the central part of the fixation stand 14 so as to be rotatable; after that, the bobbin is turned to its tight winding direction; the diameter of the superconducting cable 1 is reduced sequentially to the side of the bobbin; a superconducting pancake coil 20 in which each part between windings becomes mutually dense is formed; after that, the coil is bound. One end of the tight wound coil 20 is loosened; a tape insulating layer is formed; after that, the coil is wound tight or the tape insulating layer is formed in a state that the superconducting cable 1 is in a spiral shape.
