マク形核融合装置に用いられるディスク形のトロイダル
コイルに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates generally to nuclear fusion devices, and more particularly to a disk-shaped toroidal coil used in a tokamak-type nuclear fusion device.
従来この種のトロイダルコイルを備えた核融合装置は、

符号１は、センターポールで、このセンターポール１に
接してトロイダルコイル２が設けられている。Conventional fusion devices equipped with this type of toroidal coil are
It was constructed as shown in FIGS. 1 and 2.
Reference numeral 1 denotes a center pole, and a toroidal coil 2 is provided in contact with the center pole 1.

When a direct current is passed through the toroidal coil 2, a magnetic field is generated in the donut-shaped space surrounded by the coil, and the plasma position within the vacuum vessel 2a is stabilized.

。Since this magnetic pressure increases in inverse proportion to the distance from the center of the center pole 1, there is a drawback that the compressive force applied to the insulating portion is greatest near the contact surface PQ with the center pole 1. By equalizing the compressive force applied to the insulator in the direction of PQ, the local maximum compressive stress can be eliminated. As an example of this method, a method has conventionally been adopted in which the support structure of the center pole is changed in the PQ direction to adjust the spring constant. However, this method is quite complicated and difficult to work with, and as long as the overall centripetal force is constant, it is impossible to reduce the stress below a certain value. This invention reduces the compressive stress applied to the insulator by reducing the total centripetal force due to electromagnetic force and keeping the support spring constant of the center pole close to a constant value.
The purpose of this invention is to provide a nuclear fusion device equipped with a toroidal coil that requires ordinary insulation. Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

きる。Since the electromagnetic centripetal force directed toward the center ball 1 is a constant value determined by the shape and dimensions of the coil 2, the contact apex Q
In order to reduce the insulation stress in the toroidal coil 2, a force (centrifugal force) in the opposite direction to the centripetal force described above may be applied to a part of the toroidal coil 2. The above-mentioned insulation stress is due to the transmission force between the wire 3 forming the toroidal coil 2 and the can 5. Therefore, when the bending rigidity of the wire 3 is large, that is, the fifth
As shown in the figure, the length b of the wire 3 along the radial direction of the toroidal coil 2 is larger than the length a of the coil 2 along the circumferential direction, and the relationship b/a>1 is established. In such cases, a configuration in which load applying members such as lobes 13 and 14 according to an embodiment of the present invention are provided is particularly effective. Further, since the toroidal coil 2 undergoes thermal expansion vertically and horizontally due to temperature rise, it is best to use a coil with a spring constant as small as possible in order to apply centrifugal force, and from this point of view as well, the lobes 13 and 14 are provided. The configured configuration is valid. In the above, the can 5 is configured as an integral unit, but it can also be configured as a divided unit as shown in FIG.

がある。As described above, according to the present invention, a load applying portion is provided on the other side of the toroidal coil for applying a load to the toroid in the direction opposite to that on the center ball side, thereby reducing compressive stress applied to the insulator. This has the effect of providing a nuclear fusion device equipped with a toroidal coil for which a normal insulation method is sufficient.
