Abstract: A control system for at least one vacuum interrupter gap in a high-voltage switching device includes at least one non-reactive control resistor disposed in parallel with the vacuum interrupter. The non-reactive control resistor merges concentrically onto the vacuum interrupter chamber and is mechanically and electrically coupled thereto.

Abstract: A vacuum chamber having at least one insulating cylinder whose end faces are closed with the aid of one cover each is described. The vacuum chamber has a movable contact stem and a movable contact piece that is attached thereto and opposite which there is a correspondingly constructed a fixed contact piece. Fastened in a vacuum-tight fashion between the one cover and the movable contact stem is a sealing element which permits movement of the contact stem and is constructed as a bellows. The cover is of cup-shaped construction in this case, and is fastened with its free edge end, which has a section of reduced wall thickness, on the end face of the insulating body, a support ring being provided which produces a mechanical reinforcement in the region of the connection of the free edge of the cover to the insulating body. Moreover, the bellows is also of multi-layered construction, if appropriate.
