Abstract

The invention discloses a vacuum pressure impregnation Joule heating feeding lead-out electrode processing device and method thereof, which comprises a vacuum pressure impregnating stainless steel mold and a feeding electrode. The cooperation of the type sealing ring, the insulating bush and the insulating pressing bush realizes the treatment of the formed multi-layer sealing surface, so as to realize the dynamic sealing requirements under the cold and hot cycle. And through the structure of the insulating bushing to achieve the electrical insulation performance between the feed electrode and the vacuum pressure mold, the locking thread needs to be silver-plated to prevent the "seizure" phenomenon of the stainless steel parts under high temperature, thereby avoiding vacuum pressure impregnation Mold scrapping.

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...
