Definitions

  • the invention relates to a switching drive for a circuit breaker with the switching positions ON-OFF GEERDET, especially for switching off high currents in gas-insulated Medium voltage switchgear.
  • the object of the invention is to provide a switching drive with the switching positions ON-OFF GEERDET Make according to the preamble of claim 1 so that this with the same space and substantially equal operating energies, especially for the normal one Switching operation by hand, mechanically and dynamically higher load capacity.
  • the invention is that the two-armed shift lever lever, with his one arm with a Heidelbergermit legislative and with his other arm with a Erdermit commentary over in each case a trained on this guide slot and arranged on the respective arm Carrier element is in operative connection, is designed so that the switch driver side Arm of the selector shaft lever on the side facing away from the two actuating shafts arranged at an obtuse angle to the erdermit instructional matter arm and against this is considerably extended, and that the guide slot of the Wegermitsacrificings switching shaft lever side at a distance from the drive element located in the OFF switch position is extended for pivoting it to the GEERDET position.
  • the angled and extended shift shaft lever allows the transmission of a much higher torque at an otherwise unchanged spatial assignment of the coupling elements; so even with almost unchanged housing dimensions.
  • the guide slot of the GmbHermit influences the guide slot in the region of the pivot path of the driving element.
  • the is relevant to a circuit of the switch from OFF to ON and back is the guide link designed so that they transversely to the driving element in both directions of movement detected the operating waves.
  • the shift lever remains with its driving element in its free mobility in Erdermit parade essentially unimpaired.
  • the obtuse angle is in the range of 120 to 150 °, but preferably at 135 °. This Angle allows the lever arm of the selector shaft lever to be significantly, i. by a factor of 1.3 to 1.7, preferably to extend 1.5 times (50%), without the position of the Wegermitticss must be changed significantly.
  • the Heidelbergermit supplements retains substantially its outer size, can function when switching from off to on and back meet and enable the entrainment element when switching OFF in GEERDET and back a wide swivel path, which runs partially outside the Wegermit traditionss.
  • the Slope can be substantially tangential to the pivot path of the in the OFF-switching position located actuator and formed in close proximity to the pivot path be.
  • the switch drive can also be equipped with a switch shaft open Erdermit mecanic be.
  • the switching drive shown in the figures (especially Fig. 1) has a switch actuating shaft 1, a hingedly connected thereto GmbHermit commentary 2, a Erderbet decisiv Trentswelle 3, one of these hinged Erdermit literally 4, one with the switch blades of Phases via a connecting rod (not shown) coupled switching shaft 5 and one with this rotatably connected two-armed shift shaft lever 6.
  • a driving pin 7 is arranged in each case, with one on the respective driver 2 and 4 formed guide slot 8 and 9 is engaged.
  • the drivers 2 and 4 are arranged transversely to the actuating shafts 1 and 3 movable and by rotation the same in this transverse direction movable.
  • the switch actuating shaft 1 engages on a between two switching spring levers arranged spring suspension bolt 10 a on a spring guide rod 11 guided switching spring 12 at.
  • the GmbHermit disturbing 2 is at one of the Switch actuator shaft 1 arranged sleeve 13 articulated and is also available with a Turn-off AF in operative connection, via which a switch-off pulse on the switch actuation shaft 1 can be brought.
  • the shift lever 6 is between the Wennermitauer 2 and the Erdermitdung 4 and arranged by this driver about the axis A. the shift shaft 5 pivotally.
  • the switch driver side arm 6 a of the shift lever shaft 6 is on the side facing away from the two actuating shafts 1 and 3 side at an obtuse angle ⁇ angled from 135 ° to the erdermitt choir staffen arm 6b and 50% longer than this educated.
  • the guide slot 8 of the Wegermit Vietnameses 2 is remote from the shift lever 6 in a Area designed U-shaped and provides two opposing abutment surfaces 8a and 8b for the driving pin 7.
  • the guide slot 8 is extended to the opening and points to the the actuating shafts 1 and 3 side facing away from a slope 14. This is essentially tangentially to the pivot path RB of the drive pin located in the OFF switch position (U) 7 and in the immediate vicinity - game S - formed to this, wherein the slope 14 at a distance B from the driving pin 7 located in this position certain perpendicular to the actuating shafts 1 and 3 begins.
  • a guide rail 15 is arranged, with the Wegermit Meeting 2 is engaged.
  • the switch actuating shaft 1 For switching to the ON-switching position (E), the switch actuating shaft 1 by a Hand turn over a twisted into this externally insertable crank so far that the Switching spring 12 moves over the dead center and thereby a rotary jump of the switch actuating shaft 1 is triggered.
  • the Heidelbergermit supportive 2 is transverse to the switch actuating shaft 1 in the ON-switching position (E) shown in Fig. 2 is shifted (stroke H1), wherein located in the guide slot 8 driving pin 7 detected by the stop surface 8b is and the shift shaft lever 6, the shift shaft 5 and the switch blade clockwise in the switching position ON (E) is pivoted.
  • the switch By an opposite rotation of the switch actuating shaft 1, the switch can be brought back to the OFF position (U), wherein the Wegermit Meeting 2 detects the driving pin 7 with its stop surface 8a and the shift shaft lever 6 and thus the shift shaft 5 is rotated counterclockwise.
  • the switch From the OFF position (U), the switch can enter the GEERDET switch position (R) be switched.
  • the Erderbetquestioned Trente 3 is actuated and hinged to this Erdermit legislative 4 moves (hub H2), which is in engagement with this driving pin 7 and thus the shift shaft lever 6, the shift shaft 5 and the switch blade in Counterclockwise to the GEERDET position (R) pivots, as shown in Fig. 3.
  • the Heidelbergermit legislative 2 remains in its OFF position (U).
  • a switchback the switch to the OFF position (U) is by a reverse movement of the Erdermit demands 4 causes.
  • the switch driver-side driving pin 7 occurs again in the guide slot 8 a.
