Abstract:
1. Control apparatus for controlling electrical switchgear that has a moving contact suitable for taking up a closed position and an open position, said control apparatus being designed to move said moving contact, and comprising a stationary frame, and an output member that is mounted to move in translation relative to said stationary frame and that has a connection end for connection to the moving contact, the apparatus further comprising at least one motor and an opening mechanical spring received between an element fastened to said frame and a moving abutment element, said output member being suitable for taking up a closure position which makes it possible to place the moving contact in its closed position and in which the connection end for connection to the moving contact is situated at a point P 1 , and an opening position which makes it possible to place the moving contact in its open position and in which the connection end for connection to the moving contact is situated at a point P 2 distinct from P 1 ; said control apparatus being characterized in that it is designed such that it is capable of performing the following in succession: during an opening stage for opening the moving contact, causing the connection end for connection to the moving contact to go from the point P during a re-cocking stage for re-cocking the opening mechanical spring, moving said moving abutment element under the effect of switching on said at least one motor, while keeping the connection end for connection to the moving contact at the point P during a closure stage for closing the moving contact, causing the connection end for connection to the moving contact to go from the point P
