Abstract

The invention discloses a vacuum pressure impregnation Joule heating feed lead-out electrode processing device and a method thereof. The device comprises a vacuum pressure impregnation stainless steeldie and a feed electrode. A lead-out end of a feed motor realizes the treatment of a formed multilayer sealing surface through the matching of a locking sleeve I, a locking sleeve II, an O-shaped sealing ring, an insulating bush and an insulating pressure bush, so that the dynamic sealing requirement under cold and hot circulation is met. The electrical insulation performance between the feed electrode and a vacuum pressure die is achieved through the structure of an insulating bush, and a locking thread needs silver plating treatment, so that the phenomenon that a stainless steel piece is seized under the action of high temperature is prevented, and scrapping of the vacuum pressure impregnation die is avoided.

Description

technical field [0001] The invention relates to the field of insulation manufacturing of superconducting magnets of large-scale thermonuclear fusion devices or other large-scale electromagnetic devices or other similar insulation manufacturing fields, and specifically relates to a vacuum pressure impregnation Joule heating feeding lead-out electrode processing device and a method thereof. Background technique [0002] Thermonuclear fusion will provide mankind with inexhaustible clean energy, and the International Thermonuclear Test Reactor (ITER) plan will be built in the next ten years. Its key component is a superconducting magnet, and the performance of the superconducting magnet determines whether it can form the required plasma. During the vacuum pressure impregnation process of large magnet coils, external heating is difficult to ensure the internal temperature requirements of the coils. In order to ensure the uniformity of the heating temperature, Joule heating is ge...
