Definitions

  • the invention relates to a power storage for an on-load tap-changer.
  • On-load tap-changers are used for uninterrupted switching between different winding taps of a tapped transformer under load. Since this changeover usually takes place abruptly, on-load tap-changers generally have a force store.
  • Such an energy storage is from the DE-PS 19 56 369 as well as the DE-PS 28 06 282 already known. He is raised at the beginning of each actuation of the on-load tap changer by the drive shaft, that is stretched.
  • the known power storage essentially consists of an elevator carriage and a jump carriage, between which power storage springs are arranged as energy storage.
  • the guide rods are provided on which elevator carriage and jump carriage are mounted longitudinally movable independently.
  • the guide rods form the guide for the force-storing springs, such that in each case one force-storing spring encloses a guide rod in each case.
  • the elevator carriage is moved linearly relative to the skid carriage by means of an eccentric connected to the drive shaft, thereby tensioning the energy storage springs therebetween. If the elevator carriage has reached its new end position, the locking of the jump carriage is released. This follows now abruptly, as standing under the force of the tensioned power storage springs, the previous linear movement of the elevator carriage also linearly. From the aforementioned DE-PS 19 56 369 and DE-PS 28 06 282 It is known to convert this jump-like movement of the jump carriage by means of a roller which engages in a groove in a rotational movement of an output shaft.
  • the object of the invention is to provide a force accumulator of the type mentioned above, in a simple manner, a variation of the torque curve on the output shaft, d. H. after the conversion of the longitudinal movement of the jump carriage in a rotational movement allowed.
  • a force accumulator of the type mentioned above in a simple manner, a variation of the torque curve on the output shaft, d. H. after the conversion of the longitudinal movement of the jump carriage in a rotational movement allowed.
  • the force accumulator according to the invention with its arrangement of two rollers in conjunction with the likewise inventive interaction of these roles with a specially designed backdrop in which the rollers are guided and with their flanks mutually engaged, allows within wide limits an adjustment of the specific time and torque curves of the derived from the linear jump movement of the jump carriage rotational movement of a drive shaft to a variety of circuits and operating sequences.
  • the transmission ratio of the energy storage, both torque and speed, can be easily changed by the distance between the two roles.
  • the inventive arrangement in particular at the end of the movement of the jump carriage and thus the drive shaft, when the switching of the on-load tap-changer is completed, provided a high torque.
  • FIGS. 1 and 2 show a force storage device according to the invention in different representations, not all items described below in more detail in each representation and thus not all reference numerals are entered. In addition, in the FIG. 1 omitted the power storage springs for better presentation.
  • an eccentric disc 1 which is connected to a drive shaft, which is not shown, is also provided in the force accumulator described here, which actuates an elevator carriage 3 by moving it up and down in the direction of movement of the elevator carriage 3 arranged Mit Meetingklötze 2 acts.
  • the energy storage device has in this embodiment, three parallel extending, along the direction of movement of the elevator carriage 3 extending guide rods 4, 5 and 6, in which case two of them are enclosed by power storage springs 8. Also, a different number of guide rods and power storage springs is possible within the scope of the invention.
  • the elevator slide 3 has at its two ends linear bearing 7, these enclose one of the guide rods 4 or 5 or 6. With these linear bearings of the elevator slide 3 is stably supported and guided defined in its movement.
  • the power storage springs 8 are fixed in the direction of movement above or below in each case a displaceable spring bar with one of its ends and are supported there.
  • a boom 11 On the jump carriage 9, at the lower, the elevator carriage 3 side facing away, a boom 11 is fixed, which carries two downwardly directed rollers 12, 13. These rollers 12, 13 are arranged so that they are in a horizontal plane in a line perpendicular to the direction of movement of the jump carriage 9.
  • FIG. 4 The direction of movement of the boom 11 shown there, which corresponds to that of the jump carriage 9, is illustrated by a double arrow.
  • the two rollers 12, 13 are mounted on the boom 11.
  • the free, downwardly directed rollers themselves are rotatable.
  • the two rollers 12, 13 correspond with a specially designed gate 14, which is incorporated in the form of a groove in a flywheel 15.
  • the specially designed gate 14 will be explained in more detail below.
  • the flywheel 15 described in turn is connected to an output hub 18 in connection, which has a spline 19, which in turn is connected to an output shaft, not shown, which transmits the rotary motion generated on the on-load tap changer and thereby actuated.
  • the already mentioned gate 14 has an inner contour 16 and an outer contour 17, wherein in the middle region both contours 16, 17 are not parallel.
  • the inner width of the gate 14 is not constant, but changes.
  • the gate 14 has a Y-shaped contour, wherein the distance between the inner contour 16 and the outer contour 17 in the region of the outer regions of the three legs of the Y is approximately constant and corresponds to the diameter of the rollers 12, 13 at least approximately.
  • the width of the gate 14 increases, so that in this area one of the two rollers 12 or 13 is freely movable.
  • a drive shaft begins to rotate, with her the eccentric 1, which slides on the corresponding driver block 2 and thus the elevator carriage 3 in the longitudinal direction on the guide rods 4, 5, 6 shifts , As a result, the power storage springs 8 are tensioned. If the elevator carriage 3 has almost reached its new end position, these force storage springs 8 are maximally biased. Up to this time, the jumping carriage 9 is still locked so that it can not follow the movement of the elevator carriage 3. Shortly before the new end position of the elevator carriage 3, the lock is then triggered by a suitable actuator. This is known in principle from the prior art.
  • the linear movement of the jump carriage 9 is inventively transmitted by the two rollers 12, 13 in three temporally successive sections in a rotary motion of the flywheel 15: First, by a positive connection of the first roller 12 in the gate 14 at free-running second roller 13, then a positive connection of the second roller 13 in the gate 14 at free-running first roller 12, finally again by a positive connection of the first roller 12 in the gate 14 at free-running second roller 13th
  • Due to the mass of the flywheel 15 can be carried out in a particularly advantageous manner, a homogenization of the rotary motion generated.
  • the invention described conversion of the linear into a rotary motion results in the power storage several advantages: First of all, a variable ratio is given in a simple manner; the torque is particularly high at the beginning and at the end of the operation of the on-load tap-changer, when it is needed. Especially at the end of each change, a high torque is important to ensure that the end position of the energy accumulator is safely reached, it is reliably latched in this end position and thus the on-load tap-changer reaches its new stationary position after the switchover.
  • the invention takes into account the invention.
  • the gate 14 is variable in terms of their geometry within wide limits.
  • Inner contour 16 and outer contour 17 can be varied in shape and in their distance from one another in many ways. This adaptation to the most varied switching sequences and operating sequences of various on-load tap-changer is possible.
