Definitions
- the invention relates to an energy accumulator for a tap changer.
- Such energy stores are known from DE-PS 19 56 369.
- 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 switches are usually provided with an energy accumulator.
- the energy accumulator is pulled up by a continuously and slowly rotating drive shaft, tensioned and, after its subsequent triggering, suddenly releases kinetic energy.
- a generic energy accumulator is known from DE-PS 19 56 369. This has a pull-up slide and a latchable tension slide; springs formed as compression springs are arranged between these two slides.
- the mounting slide and the tensioning slide are provided with flanges and lie on their inner sides so that the compression springs can be tensioned between a flange of the mounting slide and a flange of the tensioning slide.
- Mounting slides and tensioning slides are slidably mounted on parallel guide rods. The mounting slide is actuated by an eccentric on the drive shaft, i. H. moved relative to the tension slide in its direction. As a result, the compression springs located between them are tensioned.
- the winding carriage has reached its end position, i. H.
- the object of the invention is to provide an energy accumulator of the type mentioned at the outset, which is of simple construction, consists of as few and simple components as possible and also works safely and reliably under air or gas.
- a particularly advantageous feature of the energy accumulator according to the invention is primarily the significantly simplified mechanical structure of the entire assembly.
- the centerpiece of this energy accumulator are only three flat components, namely a base plate, the mounting slide and a switching slide, which corresponds to the clamping slide of the prior art, all of which can be designed particularly advantageously as simple sheet metal parts.
- the necessary stops against which the springs are supported are easily molded directly onto the corresponding components as bent-over sheet metal tongues or tabs.
- Another advantage of the energy accumulator according to the invention is that both pull-up and tensioning slides are only guided on one side on fixed guide rods and are each supported and guided against each other. Tolerance compensation is thus possible in a simple manner.
- the entire arrangement places no special requirements on lubrication.
- the longitudinal movement of the tensioning carriage is tapped directly as a movement for actuating the diverter switch or step switch in this energy accumulator by means of a switching coupling.
- Fig. 1 shows an energy accumulator according to the invention in a perspective view
- FIG. 2 a base plate of this energy accumulator alone, namely a) from above and b) from below FIG. 3 a pull-up slide of this energy accumulator alone, again a) from above and b) from below FIG. 4 a switching slide of this energy accumulator alone, also a) from above and b) from below
- FIG. 1 shows the complete arrangement
- FIG. 2 shows the complete arrangement
- FIGS. 2 to 4 ie. H. the corresponding partial representations.
- 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 the component referred to in the prior art as a clamping slide.
- the base plate 1 is made of thin material, for example sheet steel. On two opposite sides, angled plates 1.1 and 1.2 or 1.5 and 1.6 are formed in pairs. The associated tabs 1.1 and 1.2 each have a receiving bore 1.3, 1.4; Likewise, the associated tabs 1.5, 1.6 each have a receiving bore 1.7, 1.8. These receiving bores are used to receive a respective guide rod 5, 6, such that the two guide rods 5, 6 extend parallel to one another, but at different heights, lengthwise through the entire base plate 1. The longitudinal direction of the individual components in the sense of this description is shown in the figures by a double arrow. At the ends, the guide rods 5, 6 are each closed by detents 5.1, 5.2 or 6.1, 6.2.
- a spring 3.3, 4.3 is arranged, which is supported against a spring seat 1.13, 1.14 of the base plate 1 and is thereby guided.
- Each of the two ratchet levers 3 and 4 has one as the actuating track 3.4 or 4.4 formed special area to which trigger rollers 7.13 and 7.14, which will be explained in more detail later, can act and thus deflect the respective latch lever 3, 4 from its rest position.
- the entire base plate can be fastened to other components of the tap changer, to which the energy accumulator belongs constructively.
- a drive shaft stub 2 leads from the underside through the base plate 1 to the top thereof.
- a mounting slide 7 is arranged above the base plate 1 and is designed to be longitudinally displaceable and is to be explained in more detail below.
- the mounting slide 7 On one of its side faces, viewed in the direction of movement, the mounting slide 7 has an integrally formed and upwardly angled tab 7.1 on which a guide roller 7.2 is fastened by means of a fastening screw 7.3.
- a guide tab 7.4 is formed, which extends over the entire length and has a guide contour 7.5, which extends in the longitudinal direction, i. H. extends in the direction of movement. As already explained above, this direction is represented by a double arrow.
- Fastening tabs 7.6, 7.7 are also arranged opposite one another on the end faces of the mounting slide 7, and one tab is also formed on the opposite side as a stop 7.8, 7.9. Furthermore, a further stop 7.10, 7.17 is integrally formed on each fastening tab 7.6, 7.7. In other words: there are two stops on each end: 7.8 and 7.10 on one side and 7.9 and 7.17 on the other side.
- Spring supports 1 1, 12 are inserted into the mounting slides on both end faces, each of which is supported outwardly against the stops 7.8 and 7.10 just described on one side and 7.9 and 7.17 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.
- This switching slide 14 has a tab 14.1 on one of its sides which is angled downwards and carries a guide roller 14.2 which is screwed on by means of a fastening screw 14.3.
- This guide roller 14.2 runs in the already 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 are again provided on both end faces, between which a further spring guide rod 17 is fastened.
- a coupling member 19 is articulated to a bearing point 18.1 on the U-beam 18 and transmits the abrupt movement of the triggered switching carriage to the respective switching means of the diverter switch or the tap changer, which are not shown here.
- mounting slide 7 and switching slide 14 with their open sides facing each other, are built into one another. Both the mounting slide 7 and the switching slide 14 are longitudinally guided on their outer side on a guide rod 5 or 6, respectively. Otherwise, the two carriages are supported against each other. This is done in that each of the two carriages has a guide contour 7.5 or 14.9 in which a 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 slide 14, and the switching slide 14 has a guide roller 14.2 which runs in the guide contour 7.5 of the mounting slide 7.
- This mechanism fixes mounting slide 7 and switching slide 14 in their relative position to one another and, moreover, can be moved individually and independently of one another.
- this energy accumulator is as follows: At the beginning of each actuation of the step switch, the drive shaft coming from the motor drive, which is connected to the drive shaft stump 2, rotates through an angle of 180 degrees. As a result, the drive roller 2.2 also rotates by this angle. The drive roller 2.2 runs in the transverse guide 7.18 of the mounting slide 7 and thus shifts it 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, i.e.
- the stops 7.8 and 7.10 on one side or the stops 7.9 and 7.17 on the other side take the corresponding rear spring support 11 or 12 with them, while at the same time the stops remaining in their rest position 14.10 and 14.12 or 14.11 and 14.13 of the switching slide 14 fix the respective front spring bracket 11 or 12.
- the mounting slide 7 is thus moved in the longitudinal direction, while the switching slide 14 remains in its previous position.
- the switching carriage 14 remains in its previous position because it is locked by the actuating rollers 3.2 and 4.2 of the latch levers 3 and 4 described, which are supported against the corresponding locking projection 14.4, 14.5.
- the energy accumulator according to the invention is particularly well suited for use in air or other gaseous insulating media, since the guides described each have one Guide roller 7.2 or 14.2 in a guide contour 14.9 or 7.5 do not have any special requirements, for example, on lubrication.
