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.

First claim

The invention claimed is:

1. 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 comprising:
an adjusting nut linked to the movable electrode and capable of rotation so as to adjust a position of the adjusting nut in relation to the movable electrode and thereby to vary an instant at which the movable electrode begins a movement towards the open position;
a driving device acting on the adjusting nut for driving the movable electrode towards the open position;
a locking device for locking the position of the adjusting nut in relation to the movable electrode; and
a threaded collar and a sleeve, the sleeve being fixed to the movable electrode and driven by the threaded collar, the threaded collar being provided with an external thread engaging with an internal thread of the adjusting nut for adjusting the position of the adjusting nut in relation to the movable electrode.

2. The actuation system according to claim 1 , wherein the driving device includes a hoop acting against a rim of the adjusting nut for driving the movable electrode towards the open position.

3. The actuation system according to claim 1 , wherein the locking device includes a locking screw for preventing the rotation of the adjusting nut.

4. The actuation system according to claim 1 , wherein the locking device includes a removable locking collar detachably mounted on the driving device, the removable locking collar including notches which engage with teeth of the adjusting nut.

5. The actuation system according to claim 4 , wherein the removable locking collar is snapped onto two lateral extensions of the driving device.

6. The actuation system according to claim 1 , wherein the sleeve is fixed to the movable electrode by a transverse fixing screw used to electrically connect the movable electrode to a connecting cable of a main circuit of the electrical connection device.

7. The actuation system according to claim 1 , further comprising:
a gudgeon screwed to the end of the movable electrode and a fixing screw for fixing the threaded collar with the gudgeon.

8. The actuation system according to claim 7 , further comprising:
an anti-torsion device provided with longitudinal splines engaging with corresponding splines of the gudgeon.
