Abstract

The invention relates to insulation assembly design, in particular to an insulation assembly which is used for insulation between a direct-current glow electrode and the wall of a vacuum chamber in the nuclear fusion reactor. The insulation assembly comprises nuts, caps, concave-convex concentric annulus gaskets, flat plate type concentric annulus gaskets having different latus rectums, an electrode fixing plate, fixed bolts, concave-convex concentric annulus gaskets each of which has a sleeve structure, the wall in the vacuum chamber, and the like. The concave-convex concentric annulus gaskets having the sleeve structure, the electrode fixing plate, the flat plate type concentric annulus gaskets having different latus rectums, the concave-convex concentric annulus gaskets and the caps sequentially sleeve the fixed bolts in an overlapped manner; each cap for fastening a ceramic insulation piece and the electrode fixing plate is arranged on one end of the corresponding fixed bolt, and the other end of each fixed bolt is connected with the wall in the vacuum chamber. The insulation assembly disclosed by the invention is directly related to the processing effect of the wall of the nuclear fusion vacuum chamber, and further the determination of the quality of plasma discharge. The insulation assembly disclosed by the invention is especially applicable to a Tokamak device, of which the first wall is provided with black lead and employs fiber, in the vacuum chamber of the fusion device.

Description

technical field [0001] The invention relates to an insulating assembly, in particular to an insulating assembly used in a nuclear fusion reactor. Background technique [0002] DC glow discharge cleaning is one of the effective methods for the wall treatment of the vacuum chamber of the nuclear fusion device. It is a steady-state discharge with electrodes: the negative electrode is the vacuum chamber, and the positive electrode is a number of electrodes extending into the vacuum chamber. The light impurities such as oxygen and carbon adsorbed on the wall of the vacuum chamber are removed by direct current discharge between the electrodes. The voltage between the two electrodes is as high as 300-400 volts. The quality of the insulation between the DC glow electrode and the wall of the vacuum chamber is directly related to the effect of the treatment of the wall of the vacuum chamber, and then determines the quality of the plasma discharge. Based on the above reasons, it is n...
