Title: COUPLING DEVICE AND METHOD FOR COUPLING AND DECOUPLING A TENSIONING MECHANISM OF A CIRCUIT-BREAKER
Abstract:
The invention relates to a coupling device (1) for a tensioning mechanism of a circuit-breaker and to a method for coupling and decoupling. The coupling device (1) comprises a first rotatable element (2) which is fastened to a shaft (4) and is in operative connection with a tensioning drive (5). Furthermore, the coupling device (1) comprises a second movable element (3) for tensioning a spring (6) which is designed to switch at least one contact of a circuit-breaker via a kinematic chain (7). The first element (2) and the second element (3) are in mechanical contact with one another in a first position for force transmission between the first and second element (2, 3). At least one element of the first and second element (2, 3) is movable into a second position in which the first and second element (2, 3) are arranged at a distance from one another and force transmission between the first and second element (2, 3) is interrupted. The movement of the at least one element of the first and second element (2, 3) into the first and/or second position occurs as a translational movement.
