ABSTRACT:
An evacuated envelope includes a cylindrical housing made of a metallic material, disc-shaped upper and lower end plates made of ceramic and stationary and movable contact rods. The envelope of the vacuum interrupter is manufactured by brazing the end plates to the housing by using a sealing member made of a hermetically deformable metallic material which deforms by thermal stress generated during a cooling process after hermetic brazing. Sealing means of the envelope is provided with surface-to-surface sealing between the seal member and the cylindrical metallic housing or the disc-shaped end plate in order to enhance the sealing performance. The envelope is hermetically sealed by deforming the sealing member after brazing the sealing member to the housing in order to further enhance the sealing performance. The sealing member further comprises a stress absorbing means provided with a curved portion for absorbing thermal and mechanical stress.
