Definitions
- the invention relates to a control for a power switch with several poles, in particular a vacuum switch for medium voltage, comprising a rotary control shaft on which several cams associated respectively with the poles of the switch, each cam being coupled to the movable contact of the associated pole via an oscillating lever coupled to the cam by a connecting rod and to the movable contact of the pole by a pusher in such a way that a rotary movement of the cams is transformed into a movement in translation of the movable contacts of the poles.
- the object of the invention is to propose another construction of this command to overcome the need to provide the same distance between adjacent cams and between adjacent poles. More specifically, an object of the invention is to make it possible to control different multipole switches with different distances between adjacent poles without the need to change the distance between adjacent cams of a control of these switches.
- the subject of the invention is an order as defined more high, characterized in that the connecting rods are coupled to the oscillating levers by through a common cross.
- the swing levers can be coupled to the poles regardless of the distance between cams adjacent along the control shaft. This command can therefore be used for different distances between adjacent poles without intervention on the shaft control.
- control of a three-phase circuit breaker having three vacuum interrupter 9 includes a main control shaft 1 whose rotation is ensured by a spiral spring (not shown).
- Main tree 1 extends parallel to the alignment of the three vacuum interrupters 9 of the circuit breaker.
- Three cam devices 3 associated respectively with the three bulbs with vacuum 9 are mounted on the control shaft 1 while being spaced from one another from a certain fixed distance.
- the shaft 1 and the three cam devices 3 are move in a rotary motion.
- the spiral spring housed in the spring cage 2 is bandaged by means of a manual mechanism or motorized winding not shown.
- the three cam devices 3 are coupled to the movable contacts (not shown) of the three empty bulbs 9 via three levers oscillating 6 each coupled to a cam device 3 by a connecting rod 4 and movable contact of the vacuum interrupter associated by a compression bar or pusher 8 which means that a rotary movement of the cams 3 is transformed into a translational movement of the movable contacts of the vacuum interrupters 9.
- the connecting rods 4 are coupled to the levers oscillating 6 via a common cross 5 which extends parallel to the control shaft 1.
- the movement of the cross-member 5 is transmitted to the oscillating levers 6 mounted pivoting about an axis 7 parallel to the shaft 1.
- the axis 7 can be common to the various levers 6. This movement of the oscillating levers 6 is transmitted to the movable contacts of the empty bulbs 9 via the pushers 8 as described in document EP-0385265.
