Abstract

PURPOSE:To obtain a lightweight and easily quenched coil by a method wherein, when a weight and an electromagnetic force of a superconducting coil of an impregnation-hardening type are supported, an outer circumference of the coil is surrounded by many pieces of split support rings used to fasten it within a narrow range in an axial direction and their end parts are interlinked by using bolts. CONSTITUTION:When a superconducting coil 1 is supported, its outer circumference is surrounded by, e.g., four split support rings 2 which have been spaced and their end parts are interlinked by using bolts 9. After that, support bodies 3 are attached to the rings 2; the rings 2 and the coil 1 are suspended by using the support bodies. Thereby, even when this assembly is contracted thermally by a cooling operation and the coil is contracted in an axial direction by an electromagnetic force to be caused by excitation, no binding force is caused around the support rings and no friction is produced between the rings and a support structure. Accordingly, a stress by a contraction in the axial direction is not produced inside an epoxy resin; a quenching operation on the basis of a crack of the resin is not caused.

(Problems to be Solved by the Invention) In conventional coils, the flange of the winding frame is firmly connected to the cylinder, which is difficult to connect. When the coil tries to contract in the axial direction, a restraining force is generated on the coil,
There were problems in that cracks due to the stress of the impregnated resin, peeling of the impregnated resin from the flange surface, and friction between the coil and the winding frame occurred, making it easy to become normal conductive (quench).

Furthermore, since the coil and the support ring are in contact only within a narrow range in the axial direction, friction between the support ring and the coil due to contraction of the coil does not occur. Therefore, a superconducting coil that is essentially difficult to quench can be obtained. Further, since there is a support structure only on the outer circumferential side of the coil, the inner diameter of the coil can be made smaller, and there is also the advantage that the coil ff1ffi can be made lighter.

By supporting the superconducting coil 1 with such a structure, when the coil contracts in the axial direction due to thermal contraction due to cooling and electromagnetic force when excited, there is no restraining force around the support ring, and the support ring and support rod It can be contracted without friction with supporting structures such as Therefore, no stress is generated in the epoxy resin due to axial contraction, and there is no friction of the quencher coil due to release of strain energy due to cracks in the epoxy resin, so quenching due to friction does not occur. This results in a coil support structure that is inherently difficult to quench.
