Definitions

  • the invention relates to a turn-on energy storage device for a circuit breaker, wherein a turn-on energy storage is held at a first end and connected at a second end to an eccentric of a tensioning device, cooperate with the remindiolosbeskynde means.
  • Such a power-on energy storage device for a circuit breaker is known from DE 195 03 679 Cl.
  • a switch-on spring as a switch-on energy storage is fixed at its first end and connected at its second end with a arranged on a clamping and switching shaft eccentric.
  • a backstop is designed as a back movement-limiting means; the backstop has a stop element arranged on a bushing of an elevator shaft and on a wall of the tensioning device, and a freewheel bearing. In a clamping operation while the socket is decoupled via the freewheel bearing of the elevator shaft.
  • the means have a latch mechanism arranged at the first end of the switch-on energy store.
  • the means comprise a ratchet mechanism triggering guide member, with which the first end of the switch energy storage on a fixed axis by means of an elongated hole formed in the guide member and which is connected to the second end of the switch energy storage.
  • the pawl mechanism has a pawl rotatably movable about the fixed axis between a first and a second position, to which a spring element engages.
  • the latch mechanism can be easily set up.
  • the fixed axis and the spring element are held on a fastening element. In such an arrangement, the pawl can be easily pivoted about its axis by means of the spring element between its first and its second position.
  • a stop element is provided on the guide part, which cooperates with a clamping recess on the pawl.
  • the pawl on a locking recess.
  • FIG. 1 shows a schematic representation of a turn-on energy storage device in a first position with the turn-on energy store loaded
  • FIG. 2 shows a schematic representation of the turn-on energy storage device in a second position with a partially relaxed turn-on energy store
  • FIG. 3 shows a schematic representation of the turn-on energy storage device in a third position with a relaxed turn-on energy store
  • FIG. 4 shows a schematic representation of the turn-on energy storage device in a fourth position
  • Figure 5 is a schematic representation of the turn-on power storage device in a fifth, locked
  • FIG. 1 shows a switch-on energy storage device with a spring element 1 as a switch-on energy storage, which is connected at a first end 2 by means of a latch assembly 3 with a mounting part 4 and at a second end 5 hinged to an eccentric 6.
  • the eccentric 6 and a cam 7 are fixedly arranged on a clamping shaft 8.
  • the cam 7 cooperates with a switching shaft 9, which is part of an actuating mechanism, not shown, for separable switching contacts of the circuit breaker.
  • the guide member 10 is rigidly connected to the second end 5 and by means of an axis 13 which extends through the elongated hole 11, on the fastening part. 4 stored.
  • the pawl assembly 3 comprises a likewise rotatably mounted on the axis 13 pawl 14 and a spring 15 which is fixed at its first end 16 to the pawl 14 and at its second end 17 on the fastening part 4.
  • the dashed line A corresponds to the path of movement of the second end 5 and the dashed line B of the path of movement of the stop element 12 in a switching or clamping operation of the switch energy storage.
  • the trajectory B is characterized on the basis of the kinematic arrangement of the system by the fact that during the movement of the stop element 12 from an upper to a lower dead center of the switch energy storage a different trajectory is swept over in the reverse direction, whereby the latching with the pawl 14 is made possible.
  • the switch-on energy storage is in a tensioned state, wherein the spring element is under pressure voltage.
  • the second end 5 is at the upper reversal point of its trajectory curve A
  • the stop element 12 is located near the upper knee point of its trajectory B
  • the axis 13 is located at the lower stop of the slot 11 of the guide member 10.
  • the pawl 14 is by the tensile force of the spring 15 held in a first position.
  • the energy stored in the switch-on energy store is transmitted via the eccentric 6 and the clamping shaft 8 to the cam 7 and thereby to the switching shaft 9.
  • the second end 5 moves along the line A in the counterclockwise direction and the stop member 12 on the line B in the clockwise direction.
  • FIG. 2 shows the switch-on energy storage device 1 with the pawl mechanism in a position shortly after the triggering of a switching process, wherein the switch-on energy storage device 1 has partially relaxed.
  • the energy of the turn-on energy storage 1 leads to the rotation of the cam on the tensioning shaft 8 and thus to a movement of the switch shaft 9.
  • the second end 5 is in a 9 o'clock position on the line A, while the stop element 12 on the line B has moved down.
  • the axis 13 is located relative to the slot 11 due to the movement of the second End 5 connected guide member 10 in a position close to the second end of the slot 11th
  • Figure 3 shows the switch-on energy storage in a fully relaxed state in which the second end 5 and the stopper 12 have reached the lower reversal points of the respective lines A and B.
  • the axis 13 is located at the upper end of the slot.
  • the stop element 12 bears against the pawl 14 in an L-shaped clamping recess 18.
  • the stop member 12 begins to move the rotatably mounted pawl 14 against the spring force of the spring 15 from the fastening part 4 away, wherein the spring 15 is tensioned.
  • FIG. 4 shows the position of the switch-on energy store 1 and the latch mechanism directly after the switching operation of the circuit breaker.
  • the cam 7 is not in contact with the switch shaft 9, the shift shaft 9 and thus the contacts of the circuit breaker are in a locked and on position. Due to the switching of the process partially converted into kinetic energy energy of the Einschaltergie notess 1 turn cam 7 and eccentric 6 beyond their turning points, with the guide member 10 moves upward and the stop member 12, the clamping recess 18 of the pawl 14 leaves. At this moment, the pawl 14 is moved back by the tensile force of the spring 15 in its first position.
  • FIG. 5 shows the position of the switch-on energy store 1 and the latch mechanism after the switching operation of the circuit breaker with the stop element 12 engaged.
  • the stop element 12 engages in the latching recess 19 of the latch and is locked.
