METHOD FOR MANUFACTURING OF VACUUM ARC-QUENCHING CHAMBER Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: metal-coated ends of cylindrical insulator are connected to metal disk-shaped flanges which have central holes. Hole of lower flange which is made from iron-nickel or iron-nickel-cobalt alloy contains immovable copper current conductor which has contact at its end which is made from arc-stable material. Hole of upper flange contains bellows, which is made from iron-chrome alloy. Lower part of bellows carries moving copper current conductor which has contact at its end. Said contacts are insulated against cylindrical insulator by means of metal screen which is coaxial to lower flange. Then braze using silver is put between all connection elements of chamber. EFFECT: increased functional capabilities. 1 dwg
