Definitions

  • the invention relates to an energy accumulator for a tap changer.
  • Such energy stores are from the DE-PS 19 56 369 known.
  • Step switches are used for uninterrupted switching between different Winding taps of a step transformer and thus for voltage regulation.
  • the Actual load switching must be done as quickly as possible, therefore tap changers or their diverter switch usually provided with an energy accumulator.
  • the lift mechanism will pulled, tensioned and by a continuously and slowly rotating drive shaft releases its kinetic energy abruptly after its subsequent release.
  • a generic energy accumulator is known from DE-PS 19 56 369. This has one Mounting slide and a latching tension slide on; are between these two sledges Springs designed as compression springs.
  • the mounting slide and the tension slide are provided with flanges and lie with their insides on each other so that between each a flange of the mounting slide and a flange of the clamping slide the compression springs are exciting.
  • Mounting slides and tension slides are on parallel guide rods slidably mounted.
  • the pull-up slide is supported by an eccentric disc on the Drive shaft actuated, d. H. moved relative to the tension slide in its direction. This will the compression springs in between are tensioned. When the slide carriage reaches its end position has reached d. H.
  • the object of the invention is to provide an energy accumulator of the type mentioned at the outset is simple, consists of as few and easy to manufacture components and also works safely and reliably under air or gas.
  • the power accumulator according to the invention is particularly advantageous Simplified mechanical construction of the entire assembly.
  • the core of this energy accumulator are only three flat components, namely a base plate, the mounting slide and a switching slide, the corresponds to the tension slide of the prior art, all of which are particularly advantageous as simple sheet metal parts can be executed.
  • Another advantage of the energy accumulator according to the invention consists in the fact that both mounting and tensioning slides are only fixed on one side Guide rods are guided and each support itself against the other and to lead. Tolerance compensation is thus possible in a simple manner.
  • the entire Arrangement no special lubrication requirements. Eventually, all over uncomplicated type in this energy accumulator through a switching coupling the longitudinal movement of the Clamping slide directly as a movement for actuating the diverter switch or tap changer tapped.
  • the energy accumulator according to the invention consists of three main assemblies, namely a base plate 1, a mounting slide 7 and a switching slide 14.
  • the switching slide 14 corresponds to this the component referred to in the prior art as a tension slide.
  • the base plate 1 is made of thin material, for example sheet steel. On two opposite sides are each pair of angled tabs 1.1 and 1.2 or 1.5 and 1.6 molded. The associated tabs 1.1 and 1.2 each have one Location hole 1.3, 1.4 on; Likewise, the associated tabs 1.5, 1.6 each a mounting hole 1.7, 1.8. These mounting holes are used to hold each a guide rod 5, 6, such that the two guide rods 5, 6 are parallel to one another, however, at different heights, extend lengthwise through the entire base plate 1. The The longitudinal direction of the individual components in the sense of this description is shown in the figures shown a double arrow. At the ends, the guide rods 5, 6 are each through Lockings 5.1, 5.2 and 6.1, 6.2 completed.
  • Each of the two ratchet levers 3 and 4 has one as the actuating track 3.4 or 4.4 formed special area, at the trigger rollers 7.13 to be explained in more detail later or 7.14 can attack and thus the respective ratchet lever 3, 4 from its rest position can deflect.
  • the entire base plate is on others Components of the tap changer, to which the energy accumulator belongs, can be attached.
  • a drive shaft stub 2 leads through the base plate 1 to the bottom thereof Top.
  • a mounting slide 7 is arranged above the base plate 1 and is longitudinally displaceable is formed and will be explained in more detail below.
  • the mounting slide 7 has one its, seen in the direction of movement, a molded and angled upward Tab 7.1, on which a guide roller 7.2 is fastened by means of a fastening screw 7.3.
  • On the opposite side is formed a guide tab 7.4, which extends over the entire Length extends and has a guide contour 7.5, which extends in the longitudinal direction, d. H. in Direction of movement extends. This direction is, as already explained above, by a Double arrow shown.
  • At the end faces of the mounting slide 7 are still opposite Fastening tabs 7.6, 7.7 arranged, and there is also one each opposite Shaped as a stop 7.8, 7.9.
  • 7.6, 7.7 another stop 7.10, 7.17 formed.
  • Two stops each: 7.8 and 7.10 on one side and 7.9 and 7.17 on the other side.
  • Spring ends 11, 12 are inserted into the mounting slide on both end faces, each of which follows outside against the just described stops 7.8 and 7.10 on one side and 7.9 as well 7.17 support on the other side.
  • the stop 7.17 is only indicated in the drawing in FIG. 3; it is designed in the same way as the stop 7.10 and molded onto the fastening tab 7.7.
  • a trigger roller 7.13, 7.14 is arranged, the function of which is explained in more detail below is explained.
  • the entire mounting slide 7 is supported by two longitudinal guides 8, 9, which are each screwed by means of fastening screws 8.1.9.1 on one guide rod 5 guided longitudinally.
  • the already explained guide plate 7.4 is the already explained guide plate 7.4 with the guide contour 7.5.
  • the Switching carriage 14 Another component arranged above engages in the guide contour 7.5: the Switching carriage 14.
  • This switching carriage 14 in turn has a tab 14.1 on one of its sides on, which is angled downwards and carries a guide roller 14.2, which by means of a Fixing screw 14.3 is screwed on.
  • This leadership role 14.2 is already running explained guide contour 7.5 of the mounting slide.
  • This tab 14.1 also has lateral locking lugs 14.4, 14.5.
  • Fastening tabs 14.6 and 14.7 provided between which a further spring guide rod 17 is attached.
  • On the side of the switching carriage 14 on which the tab 14.1 explained are further longitudinal guides 15 and 16 by means of fastening screws 15.1 and 16.1 attached, by means of which the switching slide 14 on the second guide rod 6 also is guided longitudinally.
  • All longitudinal guides 15, 16 are known as linear bearings executed. On the other hand, it has an analogue to the mounting slide 7 Guide tab 14.8 extending over the entire width with a guide contour 14.9. In this guide contour 14.9 runs the guide roller 7.2 described above Pull-on slide 7. Here, too, stops 14.10, 14.12 and 14.11, 14.13 provided on the other side. Finally there are still on the top pair of angles 14.14 ... 14.17, between which a U-beam 18 is arranged. The connection between the switching slide 14 and the U-beam 18 over the angle just described 14.14 ... 14.17 takes place by means of damping means 20 ... 23. A coupling member 19 is on the U-beam 18 hinged to a bearing 18.1, which the sudden movement of the triggered shift carriage to the respective switching means of the diverter switch or the tap changer, which are not here are shown, transfers.
  • mounting slide 7 and switching slide 14 with their open Sides facing each other, built into each other. Both the slide 7 and the switching carriage 14 is on its outer side on a guide rod 5 or 6 guided longitudinally. Otherwise, the two carriages are supported against each other. This happens in that each of the two carriages has a guide contour 7.5 or 14.9, in one Guide roller 14.2 or 7.2 of the other carriage runs.
  • the mounting slide 7 has a guide roller 7.2, which runs in the guide contour 14.9 of the switching carriage 14, and the Switching carriage 14 has a guide roller 14.2, which is 7.5 in the guide contour Wind-up carriage 7 runs.
  • This mechanism fixes mounting carriages 7 and Switch carriage 14 in their relative position to each other and are also individual and independent longitudinally displaceable from each other.
  • this energy accumulator is as follows: At the beginning of each actuation of the Step switch turns the drive shaft coming from the motor drive, which with the Drive shaft stub 2 communicates at an angle of 180 degrees. This turns also the drive roller 2.2 by this angle. The drive roller 2.2 runs in the transverse guide 7.18 of the Aufzugschlittens 7 and thus moves this by a certain amount in the longitudinal direction. As a result, the compression springs 13 are tensioned.
  • the tensioning takes place in that the stops on the rear side of the mounting slide 7, as seen in the direction of movement, that is to say the stops 7.8 and 7.10 on one side or the stops 7.9 and 7.17 on the other side, the take the corresponding rear spring bracket 11 or 12, while at the same time in their Stops 14.10 and 14.12 or 14.11 and 14.13 of the switching carriage remain in the rest position 14 fix the respective front spring bracket 11 or 12.
  • the slide 7 is thus in Moved in the longitudinal direction while the switching carriage 14 remains in its previous position.
  • the switching carriage 14 remains in its previous position because it is 3.2 or 4.2 of the described ratchet lever 3 or 4, which are against the corresponding Support locking lug 14.4, 14.5, is locked.
  • the force accumulator according to the invention results in comparison with the prior art a number of advantages.
  • the Base plate 1 the mounting slide 7 and the switching slide 14. All necessary means for Admission of guide rollers, for admission of the guide contours and for the stops, against the spring supports 11, 12 are supported on both sides, are simply by curved, d. H. angled sheet metal straps realized.
  • Another advantage is that despite being relatively minor Accuracy requirements for the described components given an ideal tolerance compensation is.
  • both mounting slide 7 and switching slide 14 are each only on one of the two guide rods 5, 6 directly longitudinal, otherwise they are supported against each other and practically lead themselves.
