Definitions
- the invention relates to an energy store for a tap changer according to the preamble of the first Claim.
- Such an energy accumulator is already known from DE-PS 19 56 369 and 28 06 282 and DE 199 13 814 known.
- Such an energy store is used for the sudden actuation of a diverter switch by one Step switch; it is activated by the drive shaft at the beginning of each operation of the tap changer raised, d. H. curious; excited. It essentially consists of an elevator carriage and a Output part, which is often also referred to as a spring sled, between which one or more Energy storage springs are arranged as energy storage.
- the elevator carriage is linearly relative by an eccentric connected to the drive shaft moved to the driven part, thereby the energy storage springs located in between curious; excited.
- the elevator sled has reached its new end position, the The stripping section is lifted and the stripping section is thus released.
- This abrupt linear movement of the driven part is converted into a rotary motion of a drive shaft via a sliding block and a crank.
- This then abruptly rotating output shaft in turn serves to actuate the diverter switch the tap changer, d. H. to switch between the previous and the newly selected Winding tapping under load.
- this known energy accumulator has several disadvantages.
- By converting the linear movement of the driven part over the sliding block and a pin and the crank in one Rotary movement of the driven part results in a non-uniform power transmission or Motion conversion.
- this type of movement conversion and that practically possible lever ratios on the crank the resulting angle of rotation Output shaft limited with each shift.
- this angle of rotation is about 75 degrees. This angle of rotation in turn limits the maximum possible switchover time required for actuation of the diverter switch, d. H. the uninterrupted switching, is available.
- diverter switches especially with such circuit types in which a large number of contacts, for. B.
- the object of the invention is therefore to provide a generic energy accumulator, the one uniform movement conversion allows a significantly larger angle of rotation of the output shaft and subsequently enables significantly longer switchover times when switching loads and moreover is space-saving and mechanically simple.
- a mounting plate 2, 3 are formed, on which one made of insulating material existing stator 4 is attached.
- the bearing plate 1 and the stator 4 attached to it are the central support elements for all components of the Power store according to the invention.
- the bearing plate 1 has a central opening 5, on the will be discussed in more detail below.
- In the area around Guide rods 6, 7 around the output part 9, which is also from the Guide rods 6, 7 is guided in a linearly movable manner.
- Lift carriage 8 and stripping section 9 are thus nested; this is from the left side of Figure 2 and especially from the Figure 3 clearly recognizable.
- Lift springs 10 which each run around one of the two guide rods 6 and 7.
- This eccentric 12 corresponds to two driver blocks 13, 14 on the elevator carriage 8 are attached.
- the eccentric 12 runs, depending on the direction of rotation on a driver block 13 or 14 and thus moves the elevator carriage 8 linearly right or left on the guide rods 6, 7.
- On the side of the elevator carriage 8 there is another contour 15 shown, in which a roller 16 is guided, which is connected to a lifting rod 17.
- This Lift rod 17 is through a further opening 18 in the bearing plate 1 down in the area of Diverter switch and is used to move cam disks or the like to actuate the Switching device of the diverter switch in different horizontal levels.
- a lifting mechanism is already known from the previously published WO 89/08924. Since it is not part of the invention, it should not be explained further here.
- On the underside of the stator 4 are two pawls 19, 20 arranged, which are each mounted in a pawl bearing 21, 22 and between which there is one Pawl spring 23 is located. The free ends of the pawls correspond to notches 24 and 25 am Output part 9.
- the pawls 19, 20 are actuated by ratchet rollers 31, 32, which are known per se Run on a trigger contour, not shown, of the elevator carriage 8.
- the driven part 9 has a toothing 26, for example in the form of a, on its underside linear toothed segment or a rack.
- a gear 27 which is fixed to the driven shaft 28 through the central opening 5 connected is.
- the output shaft 28 with a spline 29 is below the energy accumulator shown, on which the described, not shown here, cam disks or the like of the explained Lifting mechanism are guided vertically displaceable.
- the mode of operation of the energy accumulator according to the invention is as follows: At the beginning of each switchover rotates the drive shaft 11 and with it the eccentric 12, which on one of the two driver blocks 13 or 14 runs up and the elevator carriage 8 to the right or left depending on the direction of rotation Guide rods 6, 7 moves. By moving the elevator carriage 8 relative to Output part 9, the spring springs 10 arranged between them are tensioned. Did he Elevator carriage 8 reaches its new end position, so runs, depending on the direction of movement, one of the two ratchet rollers 31 or 32 on the release contour, which is not shown. In the The corresponding pawl 19 or 20 results from the respective catch 24 or 25 of the driven part 9, with which she was previously engaged.
- the driven part 9 which has been locked up to now follows abruptly following the movement of the elevator carriage 8.
- the stripping section 9 is also on the Guide rods 6, 7 guided; the spring springs relax due to the sudden movement 10.
- one of the two pawls 19 or 20 comes into play again in engagement with the respective catch 24 or 25 and locks the driven part 9 again.
- trailing toothing 26 the gear 27 on the output shaft 28 and thus the Output shaft 28 rotated.
- the resulting angle of rotation of the output shaft 28 can be selected in a simple manner within wide limits.
- support tabs 30 are also shown on the bearing plate 1, with which this bearing plate 1 For example, can be attached to the oil tank of the tap changer in a variety of ways.
- a damping device 35 on the bearing plate 1 with one or more stops, not shown, which in turn are connected to the output shaft 28 or are connected to the gear 27 corresponds. This dampens the abrupt movement of the output shaft 28 shortly before reaching the respective new end position easily possible.
- a particular advantage of the energy accumulator according to the invention is first of all that simple and even transmission of motion to the output shaft, like this above has been explained. Another advantage is the - also explained - simple Possibility of adaptation to a required angle of rotation of the output shaft 28 to the Different requirements of the respective diverter switch, which in turn by number, type and Depend on the sequence of the switching means to be actuated in detail. After all, that is Force storage device according to the invention constructed in a particularly space-saving manner. This is because Elevator carriage 8 and driven part 9 are nested in one another around the guide rods 6, 7 are constructed and the driven part 9 partially encloses the elevator carriage 8 in cross section.
