が配置されている。 Generally, a tokamak-type nuclear fusion device has a circular vacuum vessel 2 in the center that confines plasma 1, as shown in FIG. Spacers 4 for maintaining the spacing between the toroidal magnetic field coils 3 are attached to upper and lower frames 5 and 6 and arranged alternately. The upper and lower frames 5 and 6 are supported by a central column 7, and a poloidal magnetic field coil 8 for plasma control is installed around the vacuum vessel 2.

トロイダル磁場コイル３を転倒させようとするモ
ーメントが生じる。 In the nuclear fusion device having the above configuration, one of the electromagnetic forces generated in the toroidal magnetic field coil 3 is a force F whose direction is opposite above and below the toroidal magnetic field coil 3, as shown in FIG. A moment is generated that tends to overturn the toroidal magnetic field coil 3.

ている。 Conventionally, as a method of supporting this, as shown in FIGS. 1 and 2, spacers 4 are attached to the upper and lower frames 5 and 6, and a cotter 15 is inserted between the spacer 4 and the toroidal magnetic field coil 3. A means is adopted to transmit the overturning force F to the frames 5 and 6.

ロイダル磁場コイル側面とスペーサとは高精度で
当たる必要がある。 By the way, nuclear fusion devices are becoming larger year by year, and along with this, the electromagnetic force generated in the toroidal magnetic field coil is also increasing, and the overturning force F has become enormous, reaching several hundred tons. . Therefore, the pressure-receiving area of the spacer surface that receives the force requires a considerably large area due to the pressure limit, and the side surface of the toroidal magnetic field coil and the spacer need to contact with high precision.

面とスペーサ面とが平行になるとは限らず、また
修正も非常に困難であるからである。 However, with the conventional cotter method described above, high precision surface contact cannot be expected. This is because the toroidal magnetic field coil surface and the spacer surface are not always parallel to each other due to manufacturing errors and installation assembly errors between the toroidal magnetic field coil and the spacer, and correction is also extremely difficult.
一方、トロイダル磁場コイルとスペーサとの当

にある。 The present invention has been made in view of the above points, and its purpose is to provide a nuclear fusion device that maintains the contact between the toroidal magnetic field coil and the spacer with high precision and does not adversely affect the coil insulator. There is something to do.

の目的を達成するようになしたものである。 The present invention surrounds a vacuum container that stores plasma inside, and is arranged between a plurality of toroidal magnetic field coils arranged at predetermined intervals in the circumferential direction of the torus to confine and hold the plasma, and to control the upper and lower toroidal magnetic field coils. The spacer supported on the frame is formed into a wedge shape, and a groove is provided on the contact surface of the spacer with the toroidal magnetic field coil,
By arranging a pad with a heat or time-hardening member in the groove of the spacer and inserting it between the toroidal magnetic field coils, and then hardening the heat or time-hardenable member, the desired effect is achieved. It was designed to achieve the purpose of
以下本発明を第３図および第４図に示す一実施

る。 In the figure, 14 is a wedge-shaped spacer arranged between adjacent toroidal magnetic field coils 3, and this spacer 14 is provided with grooves 9 on both sides thereof, and the bottoms of both grooves 9 are connected. A varnish outflow hole 10 is provided to release the varnish to the atmosphere.

The varnish-impregnated nonwoven fabric 11 hardens over time (or by heating),
During a short period of time, when pressure is applied, the varnish flows out through the varnish outflow hole 10, and the thickness of the varnish-impregnated nonwoven fabric 11 changes. That is, the thickness of the varnish-impregnated nonwoven fabric 11 changes depending on the contact between the toroidal magnetic field coil 3 and the pressure receiving pad 12.

転倒力に耐える面が得られる。 The strength of the varnish-impregnated nonwoven fabric 11 depends on the amount of varnish, and appropriate pressure is required to prevent the generation of voids. Therefore, if the pressure due to the wedge action of the spacer 14 and the amount of varnish impregnated are appropriately selected, It is possible to maintain the contact of the pressure receiving pad 12 surface with high precision and to obtain a surface that can withstand falling force.
