Definitions

  • the invention relates to a jump drive for electrical switching devices, in particular for medium-voltage switchgear.
  • This spring drive device has a rotationally fixed to the drive shaft connected actuating and tensioning disc for one in a substantially transverse to the drive shaft given plane arranged drive spring and a rotatably mounted on the drive shaft and on the drive spring on the drive shaft side articulated transmission member. This in turn is connected to the switch shaft of the switching device via a linkage.
  • the actuation and The tensioning disk acts with the hinge pin connecting the drive spring to the transmission element together and has a circular sector-shaped cutout to form a length limited movement path and of driving flanks for this and thus also for the transmission element and the mainspring on.
  • the actuating disc When the switching device is switched off and also when it is switched on by actuating the Drive shaft, the actuating disc is also rotated and carried out, taking the hinge pin with it until the dead center is reached, a forced movement with energy absorption in the drive spring. After the dead center is exceeded, the drive spring relaxes, releasing spring energy abruptly and independently of the action of the operator, so that depending on the design of the switch always the same switching energy and switching speed are available and the opening and closing of the contacts of the switch ultimately independent of subjective influences by the operator.
  • a disadvantage of this drive is that when the drive shaft is actuated in the switch-off direction failure can occur and the drive spring probably over the dead center and behind this in a stable Position can be reached, however, without the contacts being separated, since those for separating the contacts required switching energy, especially with a higher short-circuit power with accordingly higher contact forces or switches that have not been adequately maintained for a long time, from the mainspring is not available. is applicable.
  • the position reached is stable, the is Spring drive not in its defined end position for a completed shutdown. In case of carelessness by the operator, i.e. if this position is maintained, the switch remains closed.
  • the invention has for its object a jump drive for electrical devices according to the To design the preamble of claim 1 so that the required when switching off the switching device Switch-off force to overcome the contact forces is reliably applied and transmitted.
  • the invention is that in a substantially a drive shaft with a non-rotatably on this arranged actuating disc for a drive spring and a rotatable on this drive shaft mounted and articulated on the drive spring transmission link, which is connected by a linkage acts on the switch shaft, having jump drive between the transmission member and the connecting rod a compression spring arranged on one of the two spring drive parts is provided, which in the event of a switch-off movement after the
  • the compression spring is preferably arranged on the transmission link and for engagement with the connecting rod mounted on a spring guide rod aligned with this.
  • the linkage can on the drive shaft side via a hinge pin on a rotatable on the drive shaft mounted drive lever be articulated. This drive lever then serves as an abutment for the compression spring.
  • the actuating disk has an annular recess in an advantageous and known manner Formation of a movement path and driving flanks for the drive spring with the transmission member connecting hinge pin.
  • the transmission link also has such a recess for the connecting rod with the Drive lever articulated connecting hinge pin. This allows a drive movement in a simple manner of the transmission link, caused by released spring energy, on the connecting rod respectively.
  • the spring drive shown in Fig. 1 for a switching device has a drive shaft 1 and a rotationally fixed connected with this actuating disc 2 with an annular recess 3 with two driving flanks 4 for a hinge pin 5 on a perpendicular to the drive shaft 1 on a spring guide rod 6 arranged drive spring 7 and a rotatably mounted on the drive shaft 1 Transfer element 8 is arranged, which is connected via a linkage 9 with the, not shown Switch shaft of the switching device is in operative connection.
  • the drive spring 5 is on the drive shaft 1 facing away from an abutment 10, which has a recess 11 for the spring guide rod 6 has.
  • the transmission link 8 designed as a double lever is also with a annular recess 12 for forming a movement path and driving flanks 13 for Provide a hinge pin 14, via which the connecting rod 9 on a on the drive shaft 1st rotatably mounted drive lever 15 is articulated.
  • a bracket 16 for one Slidably arranged spring guide rod 17 is attached, on which a compression spring 18 is arranged.
  • the bracket 16 is designed so that the spring guide rod 17 tangential to the recess 12th arranged and can be brought into engagement with the drive lever 15.
  • the transmission member 8 reaches the drive lever 15 with the compression spring 18 and is compressed and in turn pushes the transmission member 8 back with the drive spring 7.
  • the operator again drives the drive shaft 1 so that the compression spring 18 is fully compressed and "on block” pressed on the drive lever 15 and the switch-off process with the support of the operator is triggered, the drive spring when overcoming the required breakaway force 7 and the compression spring 18 relax and ensure a high switching speed.
  • 2 is the Position of the spring drive shown, in which the compression spring 18 purchase block "abuts the drive lever 15.
