PROBLEM TO BE SOLVED: To provide a winding method of a superconductor which has been heat-treated, where bending strain is controlled without having to move a drum for conductor supply. SOLUTION: In this winding method of a superconductor which has been heat-treated, the superconductor is wound with a drum for conductor supply which can be rotated at a fixed position, led out from the drum while bending strain is restricted and disposed at a winding start position on a winding frame. As the winding work progresses, bending strain is estimated by analysis using a finite element method. On the basis of estimation, by rotating the drum at a constant position, the superconductor is wound while bending strain is adjusted, and a winding is formed. When bending strain is adjusted, the position of a conductor supplying port, the position of winding to the winding frame and a conductor length between the above positions are adjusted. The lee-out angle of the superconductor in the tangential line direction of the drum and an angle of the superconductor to a tangential line direction of the winding frame at the position of winding are adjusted. |
