Problems solved by technology

It can be seen that the joint effect of electromagnetic force and temperature change makes the joint of each turn of the coil used to connect the central column and the outer arm bear a huge force, which makes the joint easy to be damaged and brings the danger of the ring field coil melting

Abstract

The invention relates to the technical field of fusion reactions, and provides a connecting joint, a toroidal field coil and a fusion reaction device. The connecting joint comprises a first joint body and a second joint body, wherein the first joint body and the second joint body are connected through a plurality of flexible conductive bands arranged at intervals, and the length of each flexible conductive band is larger than the distance between the end, close to the corresponding flexible conductive band, of the first joint body and the end, close to the corresponding flexible conductive band, of the second joint body. The toroidal field coil comprises a central column, an outer arm and a connecting joint. The fusion reaction device comprises a plurality of turns of toroidal field coils. According to the invention, the connecting joint comprises flexible conductive bands, a first joint body and a second joint body, the length of the flexible conductive band has a certain allowance, and when a central column and an outer arm generate relative displacement, the shape of the flexible conductive band is correspondingly changed, so that the connecting joint adapts to position change when the outer arm generates displacement relative to the central column, the joint is prevented from being damaged and safety risks are reduced.

Description

technical field [0001] The present disclosure relates to the technical field of fusion reaction, in particular to a connection joint, a toroidal field coil and a fusion reaction device. Background technique [0002] Due to the close size and radius of the plasma ring, the central circular hole of the spherical tokamak becomes very small. In this hole, in addition to containing the vacuum chamber wall, the toroidal field coil passes through. Based on this feature, the circular field coil of the spherical tokamak is different from the traditional tokamak. The circular field coil of the spherical tokamak includes multiple turns of individual coils that can form a closed loop. Each turn of the coil is made detachable, and a complete coil loop is formed by connecting the central column and the outer arm. [0003] When the spherical tokamak is working, the total current of the toroidal field coil can reach several mA, the current of a single-turn coil can reach the order of hund...
