    摘要： A method comprising the steps of dividing constituent elements of a vacuum switchgear assembly into parts, dividing each of the parts into an upper part group (movable electrode 176, ...) which is placed on said upper plate material 12 and a lower part group (stationary electrode 178, ...) which is placed on said lower plate material, dividing each part group into insulating parts and non-insulating parts, filling spaces among non-insulating parts with a brazing material, heating these part groups at 960 °C to fix them with the brazing material, applying a brazing material to spaces between the insulating parts and parts to be brazed (supporting base 118, ...), heating these part groups at 835 °C to fix the parts with the brazing material, TIG-welding the upper plate material 12 on which the upper part groups are fixed, the lower plate material 14 on which the lower part groups are fixed, and the side plate material 16 together at their joints in an inert gas, and thus sealing the vacuum container hermetically.
