【発明の詳細な説明】
〔発明の目的〕
(産業上の利用分野)
本発明は、主に含浸硬化型の超電導コイルのコイル重量
および電磁力の支持構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention mainly relates to a support structure for coil weight and electromagnetic force of an impregnation-cured superconducting coil.
(従来の技術)
含浸硬化型の超電導コイルは、第5図に示す様にコイル
両端のフランジと両フランジを強固に結合する円筒によ

った。(Prior Art) As shown in FIG. 5, an impregnation hardening type superconducting coil has a structure in which it is fixed by flanges at both ends of the coil and a cylinder that firmly connects both flanges to support the weight of the coil and electromagnetic force.

ジンのはく離や、コイルと巻枠との摩擦が発生し、常電
導化(クエンチ)し易いという問題があった。(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).
本発明は、コイルの熱収縮が拘束されない超電導コイル
を提供することを目的とする。An object of the present invention is to provide a superconducting coil in which thermal contraction of the coil is not restricted.

締付は支持した構造のものである。(Structure of the Invention) (Means for Solving the Problems) As shown in Figures 1 to 5, the present invention has a structure in which a narrow portion in the axial direction of the coil is tightened and supported by a support ring or flange. It is.
(作 用)
このような構造とすることによって、コイルの軸方向の
収縮によって、含浸レジン内に応力が発生しなくなり、
含浸レジンにクラックが生じない。(Function) With this structure, stress will not be generated in the impregnated resin due to contraction of the coil in the axial direction.
No cracks occur in the impregnated resin.
またコイルと支持リングは軸方向に狭い範囲でしか接触

周側にしか支持構造物が無いため、コイル内径を小さく
することができ、コイルff1ffiが軽くできるとい
う利点もめる。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.

ングの結合も、バインド巻線や溶接等によってもよい。(Example) In the example shown in FIG. 1, a support ring 2 divided into four parts in the circumferential direction as shown in FIG. This is an example in which the outer circumferential axial center portion of the coil 1 is tightened and fixed, and the support ring 2 is supported by a support rod 3. The number of divisions of the support ring 2 may be two or more, and the rings may be joined by binding winding, welding, or the like.

し難いコイル支持@造となる。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.

This is an example of rings that are connected so that they can work freely. Since the friction part consists only of the movable ring and the support rod, the same effect as the example of FIG. 1 can be obtained by 1q.

It is.
本発明は、1個のコイルの支持に限らず、第5図に示す
実施例のように複数個のコイルの支持にも適用できる。The present invention is not limited to supporting one coil, but can also be applied to supporting a plurality of coils as in the embodiment shown in FIG.
