Description

Laststufenschalter mit Kraftspeicher  On-load tap-changer with energy storage
Die Erfindung betrifft einen Laststufenschalter mit einem Kraftspeicher zur Umwandlung der kontinuierlichen Drehbewegung einer Antriebswelle in eine sprungartige, schnelle Drehbewegung einer Abtriebswelle. 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.
Es sind bereits zahlreiche Kraftspeicher bekannt, die die sprungartige Drehbewegung der There are already numerous energy storage known that the sudden rotation of the
Abtriebswelle dadurch ermöglichen, dass eine oder mehrere gespannte Kraftspeicherfedern sprungartig ausgelöst werden. Solche Kraftspeicherfedern können sowohl Zug- als auch Druckfedern sein. Das Prinzip dabei ist immer das Gleiche: Eine sich drehende Antriebswelle spannt die Feder bzw. die Federn bis zu einem Maximalpunkt, danach entspannen sich diese sprungartig und bewegen dadurch die Abtriebswelle mit. Ein solcher Kraftspeicher ist aus der DE 10 2006 008 338 bekannt. Naturgemäß ist bei derartigen Kraftspeichem, bedingt auch durch die Federcharakteristik, bei Beginn der Auslösung der bis dahin gespannten Federn das Drehmoment am größten; es nimmt bis zum Erreichen der Endstellung ab. In bestimmten Fällen ist dieser vorgegebene Drehmomentverlauf, der abhängig ist von der Federcharakteristik sowie der jeweiligen Kinematik, und die daraus resultierende Geschwindigkeit der Abtriebswelle jedoch unerwünscht. Dies betrifft insbesondere solche Fälle, bei denen eine größere Zahl von Schaltelementen oder anderen Bauteilen des Laststufenschalters in einer ganz bestimmten Sequenz nacheinander betätigt werden sollen. Allow output shaft thereby that one or more tensioned power storage springs are triggered suddenly. Such power storage springs can be both tension springs and compression springs. The principle is always the same: a rotating drive shaft biases the spring or springs to a maximum point, then relax this jump and thus move the output shaft with. Such a force accumulator is known from DE 10 2006 008 338. Naturally, in such Kraftspeichem, due to the spring characteristic, at the beginning of the release of the hitherto cocked springs, the torque is greatest; it decreases until it reaches the end position. In certain cases, 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.
Angestrebt wird daher bei solchen Anwendungsfällen ein Kraftspeicher, bei dem eine gezielte Anpassung des Verlaufs der sprungartigen Abtriebsbewegung an die jeweiligen konkreten The aim is therefore in such applications an energy storage, in which a targeted adaptation of the course of the sudden output motion to the respective concrete
Erfordernisse erreicht wird. Requirements is achieved.
Aus der DE-AS 25 02 810 ist es dazu bereits bekannt, bei einem Kraftspeicher der eingangs genannten Art einen Zusatzkraftspeicher vorzusehen. Dabei ist neben den eigentlichen From DE-AS 25 02 810 it is already known to provide an additional energy storage in a power storage of the type mentioned. It is next to the actual
Kraftspeicherfedern eine weitere Feder vorgesehen, die bei der Auslösung des Kraftspeichers über ein Kniegelenk gespannt wird. Dabei wird eine Verzögerung des ausgelösten Kraftspeichers im ersten Teil des Bewegungsablaufes dadurch erreicht, dass diese zusätzliche Feder gespannt wird, während gegen Ende des Bewegungsablaufes, wenn die eigentliche Kraftspeicherfeder bereits weitestgehend entspannt ist, die Zusatzfeder ebenfalls sich entspannt, wodurch sich die Federkräfte addieren. Diese bekannte Lösung wurde seinerzeit konzipiert, um die Auslösung des Kraftspeichers zu verlangsamen, speziell dafür, um statt des üblichen Wechselstromes mit einer Frequenz von 50 Hz einen Power storage springs provided a further spring, which is stretched when triggering the force accumulator via a knee joint. In this case, a delay of the triggered energy storage in the first part of the movement is achieved in that this additional spring is stretched, while toward the end of the movement, when the actual energy storage spring is already largely relaxed, the additional spring also relaxes, resulting in the spring forces add. This known solution was at the time designed to slow the release of the energy storage, especially for, instead of the usual alternating current with a frequency of 50 Hz one
Wechselstrom von 16 2/3 Hz schalten zu können, ohne dass der Umschaltvorgang insgesamt zu schnell abläuft. Dieser bekannte Kraftspeicher ist außerdem mechanisch kompliziert aufgebaut, insbesondere durch die Rollenführung und zusätzliche Kniehebelanordnung zur Betätigung der Zusatzkraftspeicherfedern. Außerdem ist er ausschließlich vorgesehen für einen Kraftspeicher, bei dem eine Drehbewegung der Antriebswelle zunächst in einer Längsbewegung umgewandelt wird, in der die Kraftspeicherfedern gespannt werden und die schnelle Längsbewegung nach deren Alternating current of 16 2/3 Hz to switch without the switching process runs 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. In addition, 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 after their
Auslösung wieder in eine Drehbewegung der Abtriebswelle umgewandelt wird. Für die direkte Umwandlung einer kontinuierlichen in eine schnelle Drehbewegung ist die bekannte Lösung nicht geeignet. Trigger is again converted into a rotational movement of the output shaft. For the direct conversion of a continuous into a fast rotary motion, the known solution is not suitable.
Aufgabe der Erfindung ist es, einen Laststufenschalter mit einem Kraftspeicher anzugeben, wobei der Kraftspeicher außer der eigentlichen Kraftspeicherfeder bzw. den eigentlichen Federn weitere Mittel aufweist, die zur gezielten Anpassung der Drehbewegung der Abtriebswelle führen. 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.
Diese Aufgabe wird durch die Erfindung gelöst. This object is achieved by the invention.
Besonders vorteilhaft an der Erfindung ist deren einfacher Aufbau. Durch eine zusätzlich mit der Abtriebswelle in Verbindung stehende Kurvenscheibe wird ein Verbindungsteil ausgelenkt, wodurch - je nach momentaner Lage der Kurvenscheibe - eine zusätzliche Feder ge- oder entspannt wird. Die durch die zusätzliche Feder bzw. zusätzlichen Federn aufgenommene bzw. abgegebene Energie verzögert bzw. beschleunigt die Drehbewegung der Abtriebswelle gezielt und bedarfsgerecht, während sich die eigentliche Kraftspeicherfeder entspannt. Particularly advantageous to the invention is its simple structure. 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.
Die Erfindung soll nachstehend an Hand einer Zeichnung beispielhaft noch näher erläutert werden. The invention will be explained in more detail by way of example with reference to a drawing.

Die mit den Bezugszeichen 1 bis 12 bezeichneten Bauteile sind bereits aus der eingangs genannten DE 10 2006 008 338 B3 bekannt, werden hier aber zum Verständnis der Gesamtfunktion noch einmal erläutert. The components designated by the reference numerals 1 to 12 are already known from the aforementioned DE 10 2006 008 338 B3, but will be explained again to understand the overall function here.
In der Figur 1 ist eine Tragplatte 1 gezeigt, auf der der gesamte Kraftspeicher und die In the figure 1, a support plate 1 is shown, on which the entire energy storage and the
Getriebeanordnung des Laststufenschalters angeordnet sind. Weiterhin ist eine Antriebswelle 2 gezeigt, die mit einem Zahnrad 3 verbunden ist und dieses kontinuierlich antreibt. Das Zahnrad 3 seinerseits treibt ein Antriebselement 4 über dessen Verzahnung 5 an. Das Antriebselement 4 besitzt symmetrische Anschläge, die mit einer Antriebskurbel 6 korrespondieren und diese in Drehung versetzen können. Oben auf der Antriebskurbel 6 ist ein Zugstangenkopf 7 drehbar gelagert, an dem sich eine Zugstange befindet. Befestigt ist die Antriebskurbel 6 auf einer Abtriebswelle 8, die senkrecht durch die Tragplatte 1 hindurch nach unten führt. Die daran angeschlossenen Bauteile zur Betätigung der Kontakte sind hier nicht gezeigt. 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. On top of the drive crank 6, 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.
Um die Zugstange herum ist ein Federrohr 9 vorgesehen. Das Federrohr 9 ist an einer Seite an einem Lagerbock 10 angelenkt; mittels eines senkrechten Lagerbolzens 11 ist es horizontal verschwenkbar. Konzentrisch um das Federrohr 9 herum oder auch in diesem sind eine oder mehrere Druckfedern vorgesehen. Hier ist nur eine einzige Druckfeder 12 dargestellt.  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.
Die Funktionsweise des bis hierhin bekannten Kraftspeichers ist Folgende: The operation of the heretofore known energy storage is the following:
Zu Beginn jeder Umschaltung, d. h. jeder Betätigung des Laststufenschalters, dreht ein Motorantrieb über die Antriebswelle 2 das Zahnrad 3. Diese Drehbewegung wird über die Verzahnung 5 auf das Antriebselement 4 übertragen. Je nach Drehrichtung, die davon abhängt, ob die nächste  At the beginning of each switch, d. H. Each actuation of the on-load tap-changer, a motor drive via the drive shaft 2 rotates the gear 3. This rotational movement is transmitted via the toothing 5 to the drive element 4. Depending on the direction of rotation, which depends on whether the next
Lastumschaltung in Richtung„höher" oder„tiefer" erfolgen soll, gerät einer der symmetrischen Anschläge des Antriebselementes 4 in Anschlag mit der Antriebskurbel 6 und dreht diese mit. Dabei wird der Zugstangenkopf 7 mit bewegt; die Zugstange wird ausgelenkt und die Druckfeder 12 wird gespannt. Nach einer Drehung der Antriebskurbel hat die Zugstange ihre neue Endstellung erreicht; die Druckfeder 12 ist maximal gespannt. Nach Überschreiten des Totpunktes wird die Drehbewegung der Antriebskurbel 6 und damit der Abtriebswelle 8 schnell zu Ende geführt, da sich die Druckfeder 12 sprungartig entspannt. Diese schnelle Drehbewegung führt letztendlich zu einer raschen Umschaltung zwischen einzelnen Kontakten im Laststufenschalter. Switching load in the direction of "higher" or "lower" to take place, one of the symmetrical stops of the drive element 4 into abutment with the drive crank 6 and rotates with it. In this case, the drawbar 7 is moved with; the pull rod is deflected and the compression spring 12 is tensioned. After a rotation of the drive crank, the pull rod has reached its new end position; the compression spring 12 is maximally tensioned. After exceeding the dead center, the rotational movement of the drive crank 6 and thus the output shaft 8 is quickly brought to an end, as the compression spring 12 suddenly relaxes. This fast rotary motion ultimately leads to rapid switching between individual contacts in the on-load tap-changer.
Erfindungsgemäß ist auf der Antriebskurbel 6, fest mit dieser verbunden, eine Kurvenscheibe 13 angeordnet, die eine stirnseitige Kontur 14 trägt. Diese Kontur weicht, von oben gesehen, von der Kreisform ab. Sie ist in weiten Grenzen frei wählbar und kann auch richtungsabhängig unterschiedlich ausgebildet sein. Weiterhin ist ein Verbindungsteil 15 vorgesehen, das an seinem einen Ende eine Rolle 16 aufweist, die auf der stirnseitigen Kontur 14 der Kurvenscheibe 13 läuft. Das Verbindungsteil 15 ist um eine Drehachse 17 verschwenkbar und trägt an seinem anderen Ende, wiederum drehbar, einen weiteren Stangenkopf 18, der wiederum eine Führungsstange aufweist, welche in einem weiteren Federrohr an ihrem anderen Ende an einem weiteren Lagerbock 19 mittels eines weiteren Lagerbolzens 20 drehbar gelagert ist. An beiden Seiten der Führungsstange befinden sich According to the invention, 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. Furthermore, 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. On both sides of the guide bar are
Federwiderlager 21 , 22, zwischen denen eine weitere Feder 23 angeordnet ist. Auch hierbei ist wieder das eine Federwiderlager 22 fixiert, während das andere Federwiderlager 21 beweglich ist. Spring abutment 21, 22, between which a further spring 23 is arranged. Again, this one spring abutment 22 is fixed while the other spring abutment 21 is movable.
Die Wirkungsweise dieser Zusatzeinrichtung ist Folgende: The operation of this accessory is the following:
Nach Überschreiten des Totpunktes beginnt sich die Antriebskurbel 6 und damit die Abtriebswelle 8 schnell zu drehen, da sich, wie erläutert, die Druckfeder 12 sprungartig entspannt. Mit der  After exceeding the dead center, the drive crank 6 and thus the output shaft 8 begins to rotate quickly, because, as explained, the compression spring 12 suddenly relaxes. With the
Abtriebswelle 8 dreht sich auch die Kurvenscheibe 13. Dadurch wird die auf deren Kontur 14 laufende Rolle 16 und mit ihr das gesamte Verbindungsteil 15 verschwenkt. Dadurch wird die Feder 23 zusätzlich gespannt oder entspannt. Sie reduziert oder verstärkt die Energie der Druckfeder 12 und bremst oder beschleunigt damit die Drehbewegung der Kurvenscheibe 13 und damit der Abtriebswelle 8. Bei einer weiteren Drehung der Abtriebswelle 8 gerät die Rolle 16 dann in eine andere Position, in der sich die Feder 23 entspannt und ihre vorher gespeicherte Energie zusätzlich zur jetzt geringer werdenden Energie der Druckfeder 12 abgibt. Output shaft 8 also rotates the cam 13. As a result, running on its contour 14 roller 16 and with it the entire connecting part 15 is pivoted. As a result, the spring 23 is additionally tensioned or relaxed. It reduces or increases the energy of the compression spring 12 and slows or accelerates the rotational movement of the cam 13 and thus the output shaft 8. In a further rotation of the output shaft 8, the roller 16 then moves to another position in which the spring 23 relaxes and their previously stored energy in addition to the now decreasing energy the compression spring 12 delivers.
Insgesamt wird damit eine an die jeweiligen kinematischen Erfordernisse angepasste schnelle Bewegung der Abtriebswelle 8 mit weitestgehend optimiertem Drehmoment erreicht.  Overall, this is adapted to the respective kinematic requirements fast movement of the output shaft 8 achieved with largely optimized torque.
Figur 2 zeigt eine weitere Ausführungsform der Erfindung. Hierbei ist wiederum ein Verbindungsteil 15 um eine Drehachse 16 verschwenkbar und trägt wieder den Stangenkopf 18, der hier fest mit einem Federwiderlager 24 verbunden ist. Zwischen diesem und dem Lagerbock 19 ist eine Feder 25 angeordnet. Bei dieser Ausführungsform ist also die Bewegungsrichtung der Feder 25 gegenüber der in Figur 1 dargestellten Ausführungsform umgekehrt. Die Feder 25 ist am Lagerbock 19 fixiert und wird durch das Federwiderlager 24 gespannt. FIG. 2 shows a further embodiment of the invention. Here, in turn, 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. Between this and the bearing block 19, a spring 25 is arranged. In this embodiment, therefore, the direction of movement of the spring 25 with respect to the embodiment shown in Figure 1 is reversed. The spring 25 is fixed to the bearing block 19 and is tensioned by the spring abutment 24.
Die in den Figuren 1 und 2 erläuterten jeweiligen Federn 23 bzw. 25 sind demnach als Druckfedern ausgebildet.  The illustrated in Figures 1 and 2, respective springs 23 and 25 are therefore designed as compression springs.
Im Rahmen der Erfindung ist es auch möglich stattdessen Zugfedern zu verwenden. Dies ist schematisch in Figur 3 dargestellt. Allein durch die räumliche Anordnung der Drehachse 17 desIn the context of the invention it is also possible to use tension springs instead. This is shown schematically in FIG. Alone by the spatial arrangement of the axis of rotation 17 of
Verbindungsteils 15 und die Lage der Rolle 16, die auf der Kontur 14 der Kurvenscheibe 13 läuft, an dem Verbindungsteil 15 lassen sich unterschiedliche Federarten einsetzen. Connecting parts 15 and the position of the roller 16, which runs on the contour 14 of the cam 13, on the connecting part 15 can be used different types of springs.
Figur 3a zeigt eine Zugfeder 26, die ausgelenkt werden kann.  Figure 3a shows a tension spring 26, which can be deflected.
Figur 3b zeigt eine Druckfeder 23, 25, die zusammengedrückt werden kann.  Figure 3b shows a compression spring 23, 25 which can be compressed.
Es sind im Rahmen der Erfindung auch jeweils konzentrische Anordnungen von jeweils zwei oder auch mehr solcher Federn 23, 25 bzw. 26 denkbar.  In the context of the invention, concentric arrangements of in each case two or more such springs 23, 25 and 26 are also conceivable.
Weiterhin ist im Rahmen der Erfindung auch eine Ausführungsform als Geradführung möglich. Furthermore, an embodiment as a straight guide is possible within the scope of the invention.
Unabhängig von der konkreten Bauform des Kraftspeichers besteht das Wesen der Erfindung ganz allgemein darin, dass durch eine Kraftspeicherfeder nach deren Auslösung eine Abtriebswelle 8 sprungartig gedreht wird und auf diese Abtriebswelle 8 eine Kurvenscheibe 13 mit einer stirnseitigenRegardless of the specific design of the energy storage, the essence of the invention is quite generally that an output shaft 8 is suddenly rotated by a force storage spring after the triggering and on this output shaft 8 a cam 13 with an end face
