Definitions

  • the invention relates to an on-load tap changer having a force accumulator for converting the continuous rotational movement of a drive shaft into a sudden, fast rotational movement of an output shaft.
  • this predetermined torque curve which is dependent on the spring characteristic and the respective kinematics, and the resulting speed of the output shaft, however, undesirable. This applies in particular to those cases in which a larger number of switching elements or other components of the on-load tap-changer are to be actuated successively in a very specific sequence.
  • the aim is therefore in such applications an energy storage, in which a targeted adaptation of the course of the sudden output motion is achieved to the respective specific requirements.
  • This known solution was at the time designed to slow the triggering of the energy storage, especially for being able to switch an alternating current of 16 2/3 Hz instead of the usual alternating current with a frequency of 50 Hz, without the switching process taking place too fast overall.
  • This known power storage is also mechanically complicated, in particular by the roller guide and additional toggle lever assembly for actuating the additional power storage springs.
  • it is exclusively intended for a power storage, in a rotational movement of the drive shaft is first converted into a longitudinal movement, in which the power storage springs are tensioned and the rapid longitudinal movement is converted after their release back into a rotational movement of the output shaft.
  • the known solution is not suitable for the direct conversion of a continuous into a fast rotary motion.
  • the object of the invention is to provide an on-load tap-changer with a force accumulator, wherein the force accumulator except the actual energy storage spring or the actual springs further means, which lead to the targeted adjustment of the rotational movement of the output shaft.
  • connection cam By an additionally communicating with the output shaft in connection cam a connection part is deflected, whereby - depending on the current position of the cam - an additional spring is relaxed or relaxed. The energy absorbed or released by the additional spring or additional springs retards or accelerates the rotational movement of the output shaft in a targeted manner and as needed, while the actual energy storage spring relaxes.
  • a support plate 1 is shown, on which the entire energy accumulator and the gear arrangement of the on-load tap-changer are arranged. Furthermore, a drive shaft 2 is shown, which is connected to a gear 3 and drives this continuously. The gear 3 in turn drives a drive element 4 via the teeth 5 at. The drive element 4 has symmetrical stops which correspond to a drive crank 6 and can set them in rotation.
  • a pull rod head 7 is rotatably mounted on which a pull rod is located. Attached is the drive crank 6 on an output shaft 8, the perpendicular through the support plate 1 passes down. The connected components for actuating the contacts are not shown here.
  • a spring tube 9 is provided around the pull rod around a spring tube 9 is provided.
  • the spring tube 9 is articulated on one side to a bearing block 10; by means of a vertical bearing pin 11, it is horizontally pivotable. Concentrically around the spring tube 9 around or in this one or more compression springs are provided. Here only a single compression spring 12 is shown.
  • a cam disc 13 which carries an end-side contour 14, is arranged on the drive crank 6, fixedly connected thereto.
  • This contour differs, seen from above, from the circular shape. It is freely selectable within wide limits and can also be designed differently depending on the direction.
  • a connecting part 15 is provided, which has at its one end a roller 16 which runs on the frontal contour 14 of the cam 13.
  • the connecting part 15 is pivotable about an axis of rotation 17 and carries at its other end, in turn rotatable, another rod head 18, which in turn has a guide rod which rotates in another spring tube at its other end to a further bearing block 19 by means of another bearing pin 20 is stored.
  • FIG. 2 shows a further embodiment of the invention.
  • a connecting part 15 is pivotable about an axis of rotation 16 and again carries the rod head 18, which is firmly connected to a spring abutment 24 here.
  • a spring 25 is arranged between this and the bearing block 19, a spring 25 is arranged.
  • the spring 25 is fixed to the bearing block 19 and is tensioned by the spring abutment 24.
  • respective springs 23 and 25 are therefore formed as compression springs.
  • FIG. 3 shows a tension spring 26, which can be deflected.
  • FIG. 3b shows a compression spring 23, 25 which can be compressed.
  • concentric arrangements of in each case two or more such springs 23, 25 and 26 are also conceivable.
  • an embodiment as a straight guide is possible within the scope of the invention.
  • the invention is quite generally that an output shaft 8 is suddenly rotated by an energy storage spring after the triggering and on this output shaft 8, a cam 13 is fixed with a frontal contour 14, through which a further spring 23, 25 or 26 is relaxed or stretched as needed and thus specifically influenced by the release or absorption of energy, the speed of rotation.
  • a further spring 23, 25 or 26 is relaxed or stretched as needed and thus specifically influenced by the release or absorption of energy, the speed of rotation.
  • the energy absorption is possible either by pulling a tension spring 26 or compressing a compression spring 23, 25.
