摘要:
The invention 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, according to the preamble of claim 1, and to a contact piece for a medium voltage vacuum interrupter chamber according to the preamble of claim 12. The aim of the invention 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 constituted of at least two layers with a solder film inserted thereinbetween, said 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.

The invention relates to a method for production of a contact piece for a switchgear assembly, and to a contact piece itself, as claimed in the preamble of patent claims 1 and 15. In order in this case to introduce the slot and to apply a contact outer contour directly during the powder-metallurgical production process of the contact material, the ivention proposes that contouring, in particular via a thin plastic film, in the form of a slot or slots is introduced into the component and/or into the contact piece and/or into the powder-metal material, which is located in a mold, essentially in a direction parallel to the normal to the surface of the component or contact piece.
