摘要： A vacuum interrupter comprises a vacuum vessel 3, a pair of electrodes 4, 5 disposed within the vacuum vessel 3 so that one is in contact with the other or away therefrom, and a bellows 17 for allowing a movable electrode 5 to be movable with an air-tight relationship. The vacuum interrupter further comprises an auxiliary member 21 disposed between the bellows 17 and the vacuum vessel 3, thereby making it easy to effect the positioning of the bellows 17 and a brazing material. The auxiliary member 21 further serves as a member for absorbing and relaxing an impact appearing at the bellows when the vacuum interrupter is placed in an operational condition.

摘要： A vacuum interrupter has a hollow metallic cylinder, insulating end plates made of inorganic insulating material and connected to the opposite ends of the metallic cylinder, stationary and movable lead rods which extend into the metallic cylinder through the insulating end plates and which support separable electrical contacts, a bellows connecting the movable lead rod to the corresponding insulating end plate, and auxiliary sealing members which connect the metallic cylinder to both the insulating end plates by means of brazing. At least one of each pair of members to be brazed has a groove for solid brazing material which is closed from the vacuum chamber of the interrupter. The vacuum interrupter facilitates arrangement of the solid brazing material in a temporary assembly step and greatly reduces the amount of vaporized brazing material dispersed into the vacuum chamber of the interrupter in a vacuum brazing step. Thus, the interrupter is provided with improved dielectric strength.

摘要： A vacuum circuit interrupter includes an evacuated envelope composed of a plastically deformable metallic cylinder and first and second insulating disks closing the opposite ends of the cylinder. Stationary and movable conductive rods project coaxially through the first and second disks respectively. Stationary and movable electrodes are connected to the stationary and movable rods in such a manner as to engage with each other when the movable rod moves toward the stationary rod and disengage with each other when the movable rod moves away from the stationary rod. A bellows surrounds the movable rod inside the envelope and is fixed at its one end to the movable rod and at its other end to the second disk in such a manner as to provide a seal about the movable rod to allow for movement thereof without impairing the vacuum inside the envelope. A first conductive shield surrounds the stationary rod inside the envelope. The first shield is fixed to the first disk in such a manner as to be isolated electrically from the stationary rod and the metallic cylinder. A second conductive shield surrounds the bellows. The second shield is fixed to the second disk in such a manner as to be isolated electrically from the movable rod and the metallic cylinder.

摘要： The invention provides a vacuum interrupter in which an evacuated envelope includes a cylindrical housing made of a metallic material, disc-shaped upper and lower end plates made of inorganic insulating material 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 plastically deformable metallic material which is deformed by thermal stress generated during a cooling process after hermetic brazing. The coefficient of the housing differs from that of the upper and lower end plates. According to the present invention, the sealing performance can be enhanced, even when the thermal coefficient of the housing differs from those of the end plates, since the sealing member is used.

摘要： A vacuum interrupter has a bell-shaped metal casing made of copper or stainless steel with a copper, ring-shaped stress reduction member sandwiched between an open end of the casing and the outer periphery of a ceramic insulation disk. Since copper is plastically deformable, thermal stress generated during cooling down to room temperature following brazing of the metal casing to the ceramic insulation disk is substantially reduced, resulting in increased brazing strength so that the wall thickness of the casing can be increased. Further, since copper and stainless steel are not ferromagnetic materials, it is possible to reduce eddy currents and magnetostrictive vibration in the casing.
