Abstract: The aim of the invention is to optimize, in vacuum interrupters, the connection area (12, 13, 14) between housing parts (2, 3, 4, 5), which are coaxially assigned to one another, with regard to the complexity of production for centering measures and with regard to the execution of the soldering process. To this end, a ring-like discoidal centering means (15) is used, which is made of a silver-coated copper and which comprises centering lugs (18) located on a tubular flange (17) that is arranged on the inner periphery of the centering means. Said centering lugs extend in an axial direction of the coaxial assignment and are provided in the form of tabs that point toward the ring-like discoidal area (24) of the centering means. The centering means is thereby overlapped by a tubular copper part, which is joined to the centering means and which serves as a shielding (10) inside the vacuum interrupter.

Abstract: Vacuum interrupters having improved structural rigidity and internal vacuum integrity are provided for use in vacuum circuit breakers. Due to the design and construction of the endcap assemblies, the vacuum interrupters require a reduced total length of brazed seams, and the incidence of vacuum loss due to faulty seams is thereby reduced. An improved stationary terminal assembly including a reinforcing member providing increased structural rigidity is also provided.

Abstract: A vacuum interrupter, an envelope of which includes a pair of electrical lead rods of copper or copper-based alloy, one lead rod being brazed vacuum-tight to one end plate via a first tubular sealing member fitted onto one rod, and a bellows surrounding another lead rod, an outer end of the bellows being joined vacuum-tight to another end plate and an inner end of the bellows being brazed vacuum-tight to the other lead rod via a second tubular sealing member fitted onto the other lead rod. Each sealing member is made of an iron-based alloy and has an inner wall including a groove retaining solid brazing metal and two vacuum-tight brazing surfaces opposing each rod across a small clearance. The molten brazing metal permetates through the clearance due to wetablility and capillary action without erodingly diffusing into the opposing surfaces of the lead rods and the first and second sealing members.

Abstract: 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.

Abstract: An improved vacuum interrupter structure with a unitary end closure and end seal shield member which is sealed to the end of the generally cylindrical body of the interrupter. This member performs the function of sealing the generally cylindrical body at the opposed ends, and also to shield the seal area from hot material which may evolve from the contacts during contact opening. The resultant end shield structure provides an improved breakdown voltage characteristic for the interrupter.
