Title:
MANUFACTURE OF SUPERCONDUCTING COIL
Document Type and Number:
Japanese Patent JPH01147813
Kind Code:
A
Abstract:
PURPOSE:To obtain a superconducting coil having excellent cooling efficiency and high rigidity by a method wherein a superconducting wire is wound, a winding is impregnated with a thermo-setting resin under the state in which the winding is pushed, the excess resin is removed forcibly, an air gap is formed and the resin is heated and cured. CONSTITUTION:The whole field winding of a superconducting wire 1 wound is vacuum-pressure impregnated with a solventless epoxy resin together with a rotor. The impregnating epoxy resin is gotten rid of through a cooling hole and a cooling duct by turning the field winding, operating centrifugal force and feeding air. The epoxy resin is cured through heating together with the rotor. The epoxy resin is taken off, an air gap 7 is shaped, and a path (a duct) in which a refrigerant such as LHe passes is formed. The superconducting wires 1, lower and upper creepage blocks 15, 20, an intermediate spacer 17 and a side spacer 16 and the superconducting wire 1 and the surfaces of slots 19 are bonded simultaneously. Accordingly, a superconducting coil having excellent cooling efficiency and high rigidity is acquired.
