Definitions

  • the power chain of this mechanism is composed of a control lever 2, an earthing switch driver 4, a switch driver 6, a tumbler of a disconnector 8 and a switch tumbler 10.
  • the control lever is rotatable about an axis of rotation 12 at its center. She has an earthing switch 14 at one of its ends and a switch pin 16 at its other end. The control lever is secured to a knife shaft. From the position shown in FIG. 1A, in which the earthing switch and the switch are open, the closing of the earthing switch takes place in the following manner.
  • the operator rotates the earthing switch tumbler 8 until the neutral point of the spring passes. Once the dead point has passed, the spring disposed between the earthing switch tumbler 8 and the switch tumbler 10 (not shown) expands and causes the earthing switch tumbler 8 to rotate. The hand crank is then disengaged and no longer intervenes.
  • the tumbler 8 comes into contact with the earthing switch driver 4 by means of stops. From this moment, the driver 4 rotates at the same time as the tumbler 8. It comes into rapid contact with the pin 14 of the control lever 2 which has the effect of rotating the control lever.
  • the geometry of the switch driver 6 is such that the switch pin 16 will be able to disengage from the other driver 6 which allows the control lever 2 to continue its race. Its rotation will end when the tumbler 8 comes to stop on a small column 20.
  • the present invention specifically relates to a ground switch disconnector mechanism that overcomes these disadvantages.
  • a single spring is interposed between the switch tumbler and the earthing switch tumbler.
  • the mechanism comprises a transmission shaft secured to the control lever, this transmission shaft being introduced into a hole of the knife-shaft so as to drive the latter in rotation.
  • the mechanism of the earthing switch is disposed between a rear plate 22 and a front plate (not shown).
  • the front plate and the rear plate are spaced apart by four posts 24.
  • a disconnector tumbler 26 and a control lever 28 are rotatably mounted between the two plates about an axis of rotation 30.
  • the control lever 28 comprises a transmission axis 32 by which it drives the knife shaft 46 (see Figure 3B).
  • the transmission axis 32 passes through a slot 34 formed in the rear plate 22.
  • the control lever 28 comprises a connecting pin 36.
  • a switch tumbler 38 and a driver 40 are rotatably mounted between the two plates about an axis of rotation 42.
  • the connecting pin 36 of the control lever 28 enters a corresponding groove 45 (see FIG. In this way, the driver 40 drives the control lever 28 in rotation.
  • a spring (not shown) is interposed between the earthing switch tumbler 26 and the switch tumbler 38. The spring is mounted on spring pins 44 provided respectively on the ground switch tumbler 26 and the switch tumbler 38.
  • FIGS. 4 to 6 show three different positions of the mechanism.
  • the mechanism is in the intermediate position, the earthing switch and the switch being open.
  • closed earthing switch shown in Figure 5 using a hand crank, the operator rotates the earthing switch tumbler 26 clockwise until at the passage of the dead point.
  • the neutral point corresponds to the point at which the spring attachment pin 44 of the earthing switch tumbler 26 is aligned with the axis of rotation 30 of the earthing switch 26 and the control lever 28 and with the axis of rotation. spring clip 44 of the tumbler switch 38.
  • the spring relaxes and causes the tumbler 26 to rotate.
  • the tumbler 26 comes into contact with the control lever 28 which is associated with it, thanks to stops. From this moment, the control lever 28 rotates at the same time as the earthing switch tumbler until the position shown in FIG. 5.
  • the geometry of the groove 45 is such that the connection axis 36 can be The rotation of the tumbler 26 will end when it abuts against the baluster 24 (see Figure 5). During this movement, the control lever drives the cutter shaft via the transmission shaft 32.
  • FIGS. 7 to 9 show three positions of the earthing switch mechanism respectively corresponding to the positions shown in FIGS. 4, 5 and 6. It may be observed in these figures that the cutter shaft 46 which carries three The cutters 48 is located in the extension of the axis 30 of the earthing switch tumbler 26. In other words, the earthing switch tumbler 26, the control lever 28 and the cutter shaft 46 are coaxial.
  • FIG. 10 shows in greater detail the manner in which the control lever 28 rotates the cutter shaft 46.
  • a flange 50 is integral with the cutter shaft 46. This flange carries a hole in which the transmission pin 32 engages.
  • the control lever 28 and the cutter shaft are coaxial with the axis ZZ. The cutter shaft 46 is rotated directly by the control lever 28.
