ELEKTRISCHER DRUCKGAS-LEISTUNGSSCHALTER, INSBESONDERE SF6-HOCHSPANNUNGS-LEISTUNGSSCHALTER.

摘要

A seal monitor (6) for the electrical contacts has a one-side open connection space (9) and is coupled to a terminal block (16). In this are the tube couplings (17,28) for connection with the gas spaces of the switch, and for maintenance and for filling up. The connection space (9) protrudes into an opening (10) of a wall (7) of a control cabinet (4) open to its inside, with edges (11) surrounding the side wall of a space (9) at a distance. The connection space (9) carries a sealing sleeve (12) of elastic material. This covers the edges of the opening (10) in the cabinet wall. At the terminal block (16) support bows (29,30) are provided which are attached to the wall (7) of the cabinet (12) without connection to the sleeve (12).
