Definitions

  • Such a spring drive is known from DE-OS 28 39 424.
  • the spring is articulated at one end and the other end is articulated to the tension lever.
  • the tensioning lever is designed as a double lug, between which the connecting pin to the spring lies and has stops on both sides for the short arm of the angle lever and two pawls for delayed driving of the drive lever, which each act in both switching directions.
  • the spring After reaching the extended position, ie the position at which the longitudinal axes of the spring and the drive lever coincide, the spring suddenly relaxes and rotates the drive shaft quickly and vigorously into the other end position via the drive lever, so that the other switch position of the disconnector is reached.
  • the invention has for its object to provide a spring drive for an earthing or disconnector, in which no movement of the movable contact occurs during the tensioning of the spring.
  • the spring After overcoming the stretched position, the spring suddenly relaxes and thereby pushes the drive lever, counter to the tensioning lever, into its other end position, which means that the movable switching element is also quickly transferred to its other end position by the corresponding rotation of the drive shaft. This means that the drive lever remains in the rest position during the entire tensioning of the spring and thus the movable contact piece in its end position.
  • the switching speed in the movement of the switching element given by the relaxation of the spring is high, since more time is available for acceleration. The desired rapid switching movement is thereby achieved.
  • the spring drive 1 consists of the tension lever 3 rotatably arranged on the drive shaft 2 and the drive lever 4 rigidly connected to the drive shaft 2.
  • the side 5 of the drive lever 4 facing away from the drive shaft 2 is articulatedly connected to one end of the spring 6, the other end thereof is also articulated to the side 7 of the tensioning lever 3 facing away from the drive shaft 2.
  • the actuating lever 8 also acts on the tensioning lever 3 and, as indicated by arrows, can be moved in the direction of its longitudinal axis.
  • the figure shows the spring drive 1 in an end position of the movable switching element, not shown, of the earthing or disconnector, which is driven by the drive shaft 2 via levers, not shown.
  • This end position of the movable contact piece also corresponds to the end position of the drive lever 4 shown.
  • Movement of the actuating lever 8 in the direction of the upward-pointing arrow shifts the side 7 of the tensioning lever 3 along the circular arc 9, the spring 6 being compressed.
  • the stretched position 10 is reached, in which the direction of the longitudinal axis 11 of the tensioning lever 3 indicated by dash-dotted lines and that of the longitudinal axis 12 of the drive lever 4 indicated by the dashed lines coincide, the maximum tension of the spring 6 designed as a compression spring and thus the maximum spring force is given.
  • the spring 6 suddenly relaxes and thereby moves the drive lever 4 in the second end position indicated by dashed lines, opposite to the direction of movement of the tensioning lever 3.
  • the Tension lever 3 also runs into the end position indicated by dashed lines.
  • the drive lever 4 is thus fixed during the tensioning of the spring 6 with increasing spring force in its respective end position and only released for the rapid movement running counter to the movement of the tension lever 3 when the spring 6 relaxes after the extended position 10 has been exceeded at maximum spring force of the spring drive 1.
  • the drive shaft 2 is rotated quickly and accordingly the movable contact piece of the switch is quickly transferred from one switch position to the other switch position.
