Abstract: A system for actuating a vacuum bottle of an electrical device, the vacuum bottle comprising a fixed electrode and a moving electrode that is mobile along a longitudinal axis between a closed position and an open position. The actuating system comprises an adjusting nut that is rotatably mobile about the longitudinal axis and driven by a drive device to perform an opening movement of the moving electrode, and an adjusting screw engaging with the adjusting nut in order to vary the moment when the drive device drives the moving electrode. The moving electrode is constrained to translate along the longitudinal axis with the adjusting screw, but is free to rotate relative to the adjusting screw, and the rotation of the adjusting screw is limited by blocking means.

Abstract: A vacuum bottle that is intended for an electrical switching device includes a cylindrical body of insulating material closed at each end respectively by a first metal cover and a second metal cover, and a mobile electrode that passes through the first cover and that cooperates with a fixed electrode between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated. The bottle includes the second cover corresponding to the fixed electrode of the vacuum bottle.

Abstract: An actuation system of a vacuum bottle for an electrical connection device, the vacuum bottle including one movable electrode and one fixed electrode, the movable electrode being movable longitudinally between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated. The actuation system includes an adjusting nut linked to the movable electrode and capable of rotation for adjusting its position in relation to the movable electrode, a driving device acting on the adjusting nut for driving the movable electrode towards the open position, and a locking device for locking the position of the adjusting nut in relation to the movable electrode.

Abstract: A vacuum circuit-breaker wherein at least in one of the contacts at least one stud is used as a spacer, and is disposed between the mechanical connection portion and the circular plate of the contact body in such a manner as to avoid the collapse thereof during a closing operation of the vacuum circuit-breaker, and in the closed position the contacts can withstand very high compression forces, typically greater than 700 kg-force or 2 t-force.
