klappenanordnung at the einfahrkontaktdurchführungsöffnung in the schottwand a hochspannungsschaltzelle

摘要

Two flaps, which can pivot about in each case one axis (13a, 13b), are opened by the insertion contacts (16) during insertion of said insertion contacts (16) into the busbar or cable space and are closed again by a restoring force during withdrawal, are provided on the insertion-contact bushing opening (25) in the partition wall (26) of a high-voltage switching cell. The flap arrangement is intended to be constructed such that, with a pivoting angle of the flaps which is as small as possible, it is possible optionally to open or close a through-opening which is as large as possible. For this purpose, the two flaps (11a, 11b) which jointly cover the bushing opening (12) in the closed state can pivot out in opposite directions about pivoting axes (13a, 13b) which are essentially at right angles to the plane of the bushing opening (12). A touching-contact surface (15a, 15b) which runs obliquely with respect to the opening axis (14) is inclined such that an opening force is exerted on the flaps (11a, 11b) by the axially moved insertion contacts (16) during insertion.
