However, the GFRP winding frame, including the spacer between the coil layers, shrinks due to heat when the superconducting coil is cooled, as shown in the solenoid coil shown in FIGS. 12(a) and 12(b). Furthermore, during excitation, the superconducting coil (1) expands in the direction along the superconducting conductor, that is, in the direction of vector A, and contracts in the perpendicular direction, that is, in the direction of Muk1-B, due to electromagnetic force. There was a problem that it rose from the winding frame (2) and was easily quenched. At this time, the winding frame (2) including the spacer expands in the direction along the superconducting conductor by cooling.
If the superconducting conductor can be contracted in the vertical direction, the superconducting conductor can be firmly pressed against the winding frame even after excitation, and a superconducting coil device that is difficult to quench can be provided.

For this reason, the superconducting conductor is pressed against the winding frame and spacer with an even stronger force than after winding, and the superconducting coil expands in the direction of the superconducting conductor due to excitation, as shown by vector A shown in Figure 2 (b), and in the vertical direction. Even if it contracts, the superconducting sensitive body can be firmly pressed against the winding core and spacer with the same force as after winding.

又はセラミック繊維等の無機質の繊維を用いてもよい。When the superconducting coil device formed in this manner is cooled, the winding frame and spacer expand in the coil circumferential direction along the polyethylene fibers and largely contract in the coil axial direction perpendicular to the polyethylene fibers. Regarding this effect, Figure 3 shows the thermal shrinkage rates of GFRP and polyethylene fiber reinforced plastic (matrix epoxy) upon cooling. Polyethylene fiber reinforced plastic thermally expands in the direction along the fibers and thermally contracts in the direction perpendicular to the fibers, and its thermal shrinkage rate is much higher than that of GFHP. For this reason, by manufacturing the winding core and spacer from plastic containing polyethylene fibers in the direction along the superconducting conductor, the winding frame (2) and spacer (3) expand in the direction along the superconducting conductor and contract in the perpendicular direction. ) can be obtained. (Note that the fibers in the direction perpendicular to the conductor may be inorganic fibers such as glass fibers or ceramic fibers.

Even if the superconducting coil expands in the circumferential direction of the coil and contracts in the axial direction of the coil, the superconducting coil will not float off the winding frame.

られる。For this reason, even in the excited state, the superconducting conductor is firmly pressed against the winding frame, making it impossible for the superconducting conductor to move even slightly, and the flange (26)
When set to IP, the effect of increasing the strength of the winding frame (2) can be obtained. Therefore, a highly reliable superconducting coil device in which the superconducting coil never quenches can be obtained.
また、横断面が円形でなく、長丸状の超電導コイル装置

7) and a reinforced plastic insulator (4) and spacer (3) using epoxy resin as a matrix.
In this case as well, the superconducting coil can be more firmly restrained.

The superconducting coil can be restrained as a constant external force due to the elongation of 3) and the shrinkage of the glass fiber (5). In Figures 7 and 8, the warp is mainly made of polyethylene fiber (6), the weft is made of glass fiber (5), and cloth is interwoven with it.This fabric is wound between the layers of the superconducting coil. Make it into fiber-reinforced plastic.

傾向があるため、冷却すると変形址が大きくなる。In this case as well, when cooled, the polyethylene fibers (6) expand and the glass fibers (5) contract as shown in Figure 3, so the solenoid-like superconducting coil has internal pressure in the axial direction. This acts as external pressure from the coil and restrains the coil, making it difficult to quench. In addition, in large superconducting coil devices, the size of the winding frame (2) is also large,
Since the length tends to be longer = 7-, the deformation area becomes larger when it is cooled.

内に押えるべきである。For this purpose, as shown in Figures 7 and 8, the warp yarns are made of polyethylene fibers (6) as the main yarn, and the glass fibers (5) are used as secondary yarns, and the weft yarns are also combined in a similar manner to adjust the expansion and contraction. It also becomes possible to adjust the internal and external forces applied to the coil. For this reason, the blending ratio of the warp and weft yarns should generally be kept within 50% tension in order to allow the initial tension to remain unchanged.
