The invention concerns an interrupter device comprising a circuit breaker (1) bordered by two bar supports (3, 5), The circuit breaker (1) comprises a support column (7) mounted on a frame (9) and two interrupter chambers (11, 13) fixed on the support column in T-shaped configuration. The support column (7) is mounted mobile in axial rotation on the frame (9) via a trunnion mounting (27). Each support (3, 5) supports a bar (25) provided with a fixed contact jaw (25A) for co-operating with a conductor (11C, 13C) of each mobile interrupter chamber (11, 13), and is provided with telescopic earth connection (37, 39). The invention is characterised in that the support column (7) rotation enables to separate or connect each interrupter chamber (11, 13) contact jaw (25A) and the conductor (11C, 13C) The device thus ensures the disconnection of the open circuit breaker with a reduced number of members and controls, and is more compact and less costly. |
