Definitions

  • the invention relates to a control for a multi-pole power switch, in particular a medium voltage vacuum switch, comprising a rotary control shaft on which are mounted a plurality of cams respectively associated 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 such that a rotary movement of the cams is converted into a translational movement of the cams. mobile contacts of the poles.
  • the object of the invention is to propose another construction of this control to overcome the need to provide the same distance between adjacent cams and adjacent poles. More particularly, an object of the invention is to make possible the control of different multipole switches having different distances between adjacent poles without the need to change the distance between adjacent cams of a control of these switches.
  • the object of the invention is a control as defined above, characterized in that the connecting rods are coupled to the oscillating levers via a common cross member.
  • the swing levers can be coupled to the poles independently of the distance between adjacent cams along the control shaft. This command can therefore be used for distances between adjacent adjacent poles without intervention on the control shaft.
  • control of a three-phase circuit breaker having three vacuum bulbs 9 comprises a main control shaft 1 whose rotation is provided by a spiral spring (not shown).
  • the main shaft 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 vacuum bulbs 9 are mounted on the control shaft 1 being spaced apart from each other by a certain fixed distance.
  • the shaft 1 and the three cams 3 move in a rotary motion.
  • the spiral spring housed in the spring cage 2 is bandaged by means of a manual or motorized winding mechanism not shown.
  • the three cam devices 3 are coupled to the movable contacts (not shown) of the three vacuum bulbs 9 by means of three oscillating levers 6 each coupled to a cam device 3 by a connecting rod 4 and to the moving contact of the bulb associated vacuum by a compression rod or push rod 8, so that a rotary movement of the cams 3 is converted into a translational movement of the movable contacts of the vacuum bulbs 9.
  • the connecting rods 4 are coupled to the oscillating levers 6 via a common crossmember 5 which extends parallel to the control shaft 1.
  • a lifting movement moves the three rods 4 as in the control of the document indicated above.
  • This lifting movement is transmitted to the cross member 5.
  • the three connecting rods 4 are fixed to the cross member 5 with a fixed distance A between adjacent rods.
  • the three oscillating levers 6 are fixed on the cross member 5 according to a distance A, B, C between adjacent levers corresponding to the distance A, B, C between adjacent poles of the circuit breaker.
  • the movement of the crossbar 5 is transmitted to the oscillating levers 6 pivotally mounted about an axis 7 parallel to the shaft 1.
  • the axis 7 may be common to the various levers 6. This movement of the oscillating levers 6 is transmitted to the moving contacts vacuum bulbs 9 via the pushers 8 as described in EP-0385265.
