<p>The invention relates to a device for controlling a group of current breaking apparatuses (21, 22) via, for each current breaking apparatus, an actuation motor (M1, M2) which actuates at least one electrical contact of the current breaking apparatus. Said device comprises a single changeover contactor (11) controlled by control means (12) for connection to a power source (V) for the motors, and connected to the motors via switching means (R1, R2) for a current originating from the power source (V) and flowing through the changeover contactor (11). The invention is used for the control of current breaking apparatuses of a switch bay of a high-voltage electrical station.</p> |
