Abstract: A drive apparatus for a tensioning shaft of a spring energy drive of an electric switch has a kinematic chain for connecting a drive element to the shaft and a control element. Within the chain, a first link which can be coupled to the shaft in rotationally fixed fashion and a second link arranged coaxially regarding the first link and capable of rotating under the force of the drive element are coupled to one another in a form-fitting and/or force-fitting manner by a coupling element which is moved by the control element on one of the two links such that the link coupling is released when a predetermined first angular link position is reached and is produced again when a predetermined second angular link position is overshot. To provide the drive apparatus with a more compact configuration, the coupling element can be moved in the radial direction of the shaft.

Abstract: A control device for controlling electrical switchgear such as a circuit breaker or the like includes an actuating arm having a connection point suitable for being moved along a closed line including points P1, P2 and P3. The connection point thus moves during an opening stage for opening the moving contact, under the effect of a mechanical spring from point P1 to point P2. It also moves during a re-cocking stage for re-cocking the mechanical spring under the effect of a motor being switched on, and while keeping the moving contact in the open position, from point P2 to point P3. It also moves during a closure stage for closing the moving contact, also under the effect of the motor being switched on, from point P3 to P1. In this manner it is possible to successively perform three distinct stages of putting the actuating arm in motion, between the instant at which the moving contact leaves its closed position and the instant at which it returns thereto after having occupied its open position. A re-cocking stage for re-cocking the mechanical spring that is distinct from the closing stage and from the opening stage for closing and opening the moving contact, is performed, with the opening stage to be performed merely by releasing the energy that has been previously accumulated by the spring.

Abstract: A spring-loaded operating mechanism for a high-voltage circuit-breaker comprises, between a motor and a trigger shaft, a freewheel-type coupling device which comprises first and second friction members (5, 6) coaxially mounted on a secondary shaft (1). The first friction member (5) is screwed onto the secondary shaft (1) and the second friction member can freewheel about the secondary shaft (1) while being disposed between the first member and an axial abutment (8). The two members (5, 6) are substantially in abutment one against the other along the secondary shaft (1), and the first member is screwed or is unscrewed along the secondary shaft depending on whether it is rotated by the shaft or by the second member. The device does not require any greasing; it operates without maintenance. In addition, the forces exerted by one friction member on the other are low, thereby improving the reliability of the operating mechanism.
