Abstract: A contact piece for a vacuum interrupter chamber includes at least two layers and soldering foil interposed between the at least two layers and directly contacting the closest of the at least two layers. The at least two layers are soldered to one another in a soldering furnace with the interposed soldering foil. The at least two layers are present, prior to the soldering operation, as powder-metallurgical pressed green compacts, which are sintered at the same time as the soldering operation.

Abstract: The disclosure relates to a method for producing a contact piece, for use in a vacuum interrupter chamber, especially in a low, medium or high voltage vacuum interrupter chamber. The aim of the disclosure is to improve multi-layer contact systems in such a manner that even larger layer thicknesses can be used to improve the electrical properties. For this purpose, the contact piece is comprised of at least two layers of powder-metallurgical pressed green compacts with a solder film inserted thereinbetween, the layers being soldered together in a soldering furnace in a desired relative position to each other at the same time the layers are sintered.

Abstract: The disclosure relates to a method for producing a contact piece, for use in a vacuum interrupter chamber, especially in a low, medium or high voltage vacuum interrupter chamber, and to a contact piece for a medium voltage vacuum interrupter chamber. The aim of the disclosure is to improve multi-layer contact systems in such a manner that even larger layer thicknesses can be used to improve the electrical properties. For this purpose, the contact piece is comprised of at least two layers with a solder film inserted thereinbetween, the layers being welded together in a vacuum furnace in a desired relative position to each other. The two-layer structure can also be achieved by a powder layering process. For this purpose, the powder layers are compressed in a compression mold and then sintered in the furnace to give the finished contact piece blank.

Abstract: A process for producing a vacuum interrupter chamber includes placing spacers in bodily contact with a soldering foil and joining the spacers to the soldering foil or fixing them in a displacement-proof fashion on specially made dents in the foil, so that they can be fixed for the purpose of a reliable and simple assembly. Degassing gaps are left between soldering spacers, on which a cover of the interrupter chamber rests. The vacuum interrupter chamber is evacuated in a single furnace cycle and soldered.

Abstract: A vacuum switch chamber includes a ceramic body having two ends, two cylinder halves defining an encompassing parting line between the halves and an internal groove along the parting line. Metal caps close both of the ends. Mutually movable conductor bolts penetrate the ends. Switch contacts are disposed on the conductor bolts at a switch location. A two-part shield surrounds the switch location and has bent, adjoining, axially oriented, intermeshing inner and outer ends engaging the internal groove and spanning the parting line. The outer end has tabs distributed over the periphery of the shield and oriented toward the ceramic body.
