Method for production of a pole part of a medium-voltage switching device, as well as the pole part itself

摘要

The invention relates to a method for production of a pole part of a medium-voltage switching device, and to a pole part itself, as claimed in the preamble of patent claims 1 and 6. In order in this case to ensure that the costly pressure reinforcements are avoided at least on the switching contact side of the vacuum interrupt chamber in the area of the mold core, while nevertheless achieving an optimum injection-molded result, the invention proposes that before the encapsulation process, a compensation ring (4) is positioned as a separate injection-molded seal on or close to the external circumferential line of the vacuum interrupt chamber (1) cover, between the lower cover (5) of the vacuum interrupt chamber and the mold core (6) and then also encapsulated such that it remains as a lost seal in the encapsulation (2), with the mold core then being removed again.
