Definitions

  • the invention is in the field of high-voltage circuit breakers and can be used in the structural design of an auxiliary transmission with which switch elements are moved which lie axially opposite the driven contact group of the switch.
  • circuit breakers of this type two arcing contact pieces coaxially opposite one another are coaxially surrounded by the two continuous current contact pieces, one of which is arranged in a fixed manner and the other is designed to be axially drivable.
  • Circuit breakers of this type generally work with a gaseous extinguishing agent which, when switched, is first compressed and then flows through the separation area of the two arcing contact pieces and the flow of which can be influenced by special pressure chambers and nozzles.
  • an insulating material nozzle which is arranged within the continuous current contact pieces and surrounds the arcing contact pieces and which is firmly connected both to the drivable continuous current contact piece and to the driven arcing contact piece.
  • an axially displaceable field electrode is fastened to the end of the insulating material nozzle facing away from the first, driven arcing contact piece and surrounds the second arcing contact piece and surrounds the second arcing contact piece and which, in the issuance of the circuit breaker, the electrical field in Affects the area of the other arcing contact piece and the end of the insulating material nozzle which is subjected to high electrical stress.
  • a drive element is attached to the axially displaceable field electrode and thus to the insulating material nozzle, which also transmits the drive movement of the driven continuous current contact piece to the second arcing contact piece by means of a deflection gear.
  • the second arcing contact piece is therefore guided in a sliding contact.
  • the drive element is designed as a toothed rack, which either acts via a toothed wheel on the second arcing contact piece, which is likewise designed as a toothed rack, or which drives a push crank, the rotating part of which is formed by a toothed wheel.
  • the field electrode attached to the insulating nozzle follows the full stroke of the contact pieces; This means that the field electrode is pushed relatively far into the fixed continuous current contact piece in the switched-on position, for which purpose a corresponding space must be available.
  • the movement of the second arcing contact piece is also coupled to the full stroke of the driven contact pieces.
  • the invention has for its object to optimize the movement of the field electrode while shortening its movement stroke and, if necessary, to improve the interaction with a drive mechanism for the second arcing contact.
  • the field electrode is displaceable by means of a gearbox, which is coupled from the first, via the insulating nozzle to the drivable continuous current contact and in the direction the longitudinal axis of the switch coupling rod, consists of a parallel coupling rod coupled to the field electrode and a pivotally attached lever to the first coupling rod, with a pivot pin attached to the pivoting plane of the lever to which the second coupling rod is coupled is and which engages in a link guide, which is incorporated in a circuit board firmly connected to the second continuous current contact piece and which is designed such that a first section of the link guide runs approximately parallel to the longitudinal direction of the first coupling rod and that a second, curved section of the link guide The pin can be deflected perpendicular to the longitudinal axis of the switch.
  • the field electrode can be moved separately and separately from the drivable arcing contact piece, so that the speed and the path of the field electrode can be different from that of the first arcing contact piece, the course of the displacement movement being selectable in the form of a speed profile.
  • the special feature of the gearbox is the lever pivotally mounted on the first coupling rod with the pin attached to the pivot arm of the lever and guided in a fixed link guide.
  • a first section of the link guide runs approximately parallel to the longitudinal direction of the first coupling rod. In this area, the pin is moved along the link guide during the movement of the first coupling rod without the lever swiveling out. Only in the second section of the link guide, which allows the pin to move perpendicular to the longitudinal direction in which the coupling rod is moved, does the lever pivot out, and the pin moves at least with one component of movement perpendicular to the longitudinal direction of the first coupling rod.
  • a movement of the field electrode can thus be generated by means of the link guide, which movement takes place in the same direction as the movement of the first coupling rod, but with a different speed and variable transmission ratio. This goes so far that the pin and with it the field electrode do not move further in the longitudinal direction while the first coupling rod is moved further.
  • the field electrode with the first arcing contact piece can initially be moved at the beginning of the movement, but can be stopped before the end of the movement of the first arcing contact piece, i.e. the movement distance of the field electrode is shortened compared to the movement distance of the first arcing contact piece.
  • the curved second section of the link guide has a first end region which is adjacent to the first section and runs in the direction of the first section and a second end region which runs approximately perpendicular to the first section.
  • This configuration of the link guide allows the field electrode to move at the same speed as the first coupling rod as long as the pin is in the first section of the link guide and to delay the movement of the field electrode while the pin is in the second section of the link guide. det. -
  • the second section of the link guide expediently faces the drivable arcing contact piece.
  • the second coupling rod coupled to the field electrode can be connected to a crossmember which is displaceably guided in the direction of the longitudinal axis of the switch and which has a slot running perpendicular to the longitudinal axis of the switch, into which the pin attached to the lever engages.
  • a slot permits the necessary movements of the pin perpendicular to the longitudinal axis of the switch, the drive movement being transmitted by means of the pin to the cross member running perpendicular to the longitudinal direction of the first coupling rod and from there to the field electrode.
  • the transmission according to the invention can on the side of the high-voltage circuit breaker opposite the drive, i.e. seen from the first arcing contact piece behind the field electrode, so that the transmission is not subjected to dielectric stress due to the field strength prevailing in the area between the arcing contact pieces.

  • the design of the deflection gear is characterized by the use of fewer, simpler and lighter parts, so that the deflection gear has very small moving masses and is a self-contained assembly that can be made flat and therefore that in the fixed continuous current contact itself when switching the forming flow of the insulating gas (exhaust gas) is not impeded.
