Abstract (en)
[origin: CN105097327A] The present invention relates to a medium voltage electrical switchgear apparatus comprising at least two per phase switching devices, each switching device having a switch, this apparatus being characterized in that it comprises a bypass circuit in which a vacuum interrupter ( 9) providing the cut is disposed, said vacuum envelope (9) being actuable via one or other of a plurality of actuating means (12,13,14) respectively associated with the different disconnectors (5,6,7), such that the bypass is inactive in the steady state, and traveled by the electricity only when one of the breakers (5,6,7) has started its opening movement, by a gradual transfer of power to the line with the isolator (5) being opened to the bypass line; and in that the movable parts of the aforementioned actuation means (12,13,14) are connected mechanically and electrically to one another by a connecting rod (18).
