Umschaltung zwischen verschiedenen Wicklungsanzapfungen eines Stufentransformators gemäß dem Oberbegriff des ersten Patentanspruches. Switchover between different winding taps of a tapped transformer according to the preamble of the first claim.
Laststufenschalter sind seit vielen Jahren zur unterbrechungslosen Umschaltung zwischen verschiedenen Wicklungsanzapfungen von Stufentransformatoren in großen Zahlen weltweit im Einsatz. Sogenannte Reaktorschalter, die besonders in Nord-Amerika verbreitet sind, besitzen eine Umschaltreaktanz, die eine langsame, kontinuierliche Umschaltung ermöglicht. Laststufenschalter nach dem Widerstandsschnellschalt-Prinzip bestehen üblicherweise aus einem Wähler zur leistungslosen Anwahl der jeweiligen Wicklungsanzapfung des On-load tap-changers have been in worldwide use for many years for uninterrupted switching between different winding taps of tapped transformers in large numbers. So-called reactor switches, which are particularly common in North America, have a switching reactance, which allows a slow, continuous switching. On-load tap-changers according to the resistance rapid-switching principle usually consist of a selector for powerless selection of the respective winding tap of the
Stufentransformators, auf die umgeschaltet werden soll, und einem Lastumschalter zur eigentlichen Umschaltung von der bisherigen auf die neue, vorgewählte Stepped transformer to be switched to, and a diverter switch for the actual switching from the previous to the new, preselected
Wicklungsanzapfung. Der Lastumschalter weist dazu üblicherweise Schaltkontakte und Widerstandskontakte auf. Die Schaltkontakte dienen dabei zur direkten Verbindung der jeweiligen Wicklungsanzapfung mit der Lastableitung, die Widerstandskontakte zur kurzzeitigen Beschaltung, d. h. Überbrückung mittels eines oder mehrerer Winding tap. The diverter switch usually has switching contacts and resistance contacts. The switch contacts are used for direct connection of the respective winding tap with the load dissipation, the resistor contacts for short-term wiring, d. H. Bridging by means of one or more
Überschaltwiderstände. Die Entwicklungen der letzten Jahre führten jedoch weg von Transition resistors. The developments of recent years, however, led away from
Lastumschaltern mit mechanischen Schaltkontakten im Isolieröl. Stattdessen werden vermehrt Vakuumschaltzellen als Schaltelemente eingesetzt. Load switches with mechanical switching contacts in the insulating oil. Instead, more and more vacuum switching cells are used as switching elements.
Ein derartiger Laststufenschalter mit Vakuumschaltröhren ist beispielsweise aus der DE 10 2009 043 171 A1 offenbart. Hier trägt ein Lastumschalter eine von einem Kraftspeicher antreibbare Antriebswelle mit mindestens einer Kurvenscheibe. Die Kurvenscheibe weist mehrere Steuerkurven auf, wobei zwei an der Kurvenscheibe stirnseitig angeordnete Such an on-load tap-changer with vacuum interrupters is disclosed, for example, in DE 10 2009 043 171 A1. Here, a diverter switch carries a drivable by a power storage drive shaft with at least one cam. The cam has a plurality of control cams, two of which are arranged on the front side of the cam
Steuerkurven eine von einer Kreisform abweichende Kontur nach Art von Nocken aufweisen, an der kontaktschlüssig jeweils eine über einen Kipphebel mit einer Vakuumschaltröhre verbundene Rolle geführt wird, die die profilierte Kontur der jeweiligen Steuerkurve abgreift. Cams have a deviating from a circular contour contour on the type of cam, on the contact-connected in each case via a rocker arm connected to a vacuum interrupter roller is guided, which taps the profiled contour of the respective control cam.
Bei einer besonderen Gattung von Laststufenschaltern, den so genannten Lastwählern, sind die beschriebenen Mittel zur Anwahl einer neuen Wicklungsanzapfung und die Mittel zur eigentlichen Lastumschaltung baulich vereinigt und werden gemeinsam betätigt. In a special type of on-load tap-changers, the so-called load selectors, the described means for selecting a new winding tapping and the means for actual load switching are structurally combined and operated together.
Üblicherweise sind Stufenschalter nach dem Prinzip der Widerstandsschnellschaltung zur unterbrechungslosen Umschaltung von einer Anzapfung eines Stufentransformators zu einer anderen so aufgebaut, dass die jeweils mit den Ausleitungen der Stufenwicklungen elektrisch in Verbindung stehenden festen Stufenkontakte in einer oder mehreren horizontalen Ebene bzw. Ebenen kreisförmig an einem Isolierstoffgerüst oder - zylinder angeordnet sind und durch von konzentrischen Antriebswellen betätigte drehbare Kontaktbrücken beschaltbar sind. Bei Lastwählern, bei denen die Stufenwahl und die eigentliche Lastumschaltung kombiniert sind, erfolgt die Betätigung der Kontaktbrücken dabei sprungartig nach Auslösung eines von der Antriebswelle des Schalters aufgezogenen Energiespeichers, meist Federkraftspeichers. In der DE 42 37 165 C1 ist, abweichend von diesen üblichen Konstruktionen, ein Stufenschalter mit linearer Kontaktbetätigung beschrieben, wobei die festen Stufenkontakte längs einer Bahn sich in das Innere des Schalters erstrecken und von einem verschiebbaren Schaltmechanismus beschaltbar sind, der wiederum von der Antriebswelle angetrieben wird. Der vertikal verschiebbare Usually, tap changer are constructed according to the principle of resistance fast circuit for uninterrupted switching from a tap of a tapped transformer to another so that each with the outputs of the stepped windings electrically connected fixed step contacts in one or more horizontal plane or planes are arranged circularly on an insulating material scaffolding or - cylinder and are connected by actuated by concentric drive shafts rotatable contact bridges. In load selectors, in which the step selection and the actual load switching are combined, the actuation of the contact bridges takes place abruptly after triggering a wound up by the drive shaft of the switch energy storage, usually spring energy storage. In DE 42 37 165 C1, deviating from these conventional constructions, a tap changer is described with linear contact actuation, wherein the fixed step contacts along a path extending into the interior of the switch and are connected by a sliding switching mechanism, in turn driven by the drive shaft becomes. The vertically movable
Schaltmechanismus besteht dabei aus einem kontinuierlich von der Antriebswelle antreibbaren Aufzugsschlitten, der den neuen festen Stufenkontakt vorwählt, und einem durch den Aufzugsschlitten mittels eines Energiespeichers aufziehbarem Abtriebsteil, das nach Auslösung sprungartig dem Aufzugsschlitten nachläuft und dabei die eigentliche Lastumschaltung von der bisherigen Anzapfung der Stufenwicklung auf die vorgewählte neue Anzapfung vollzieht. Die dazu erforderlichen Schaltelemente sind Bestandteil des Abtriebsteiles. Aus der DE 198 47 745 C1 ist ein weiterer, auf die Anmelderin zurückgehender, Switching mechanism consists of a continuously driven by the drive shaft elevator carriage, which preselects the new fixed stage contact, and a aufziehbarem by the elevator carriage by means of an energy storage stripping section after triggering jumps the elevator carriage and thereby the actual load switching from the previous tap of the tap winding on the Selective new tap completes. The required switching elements are part of the stripping section. From DE 198 47 745 C1 is another, due to the applicant,
Laststufenschalter mit linear angeordneten Wählerkontakten bekannt geworden. Oberhalb der Wählerkontakte, also örtlich getrennt, befinden sich die den jeweiligen Wählerkontakten einer jeden Phase zugeordneten feststehenden Vakuumschaltröhren zur eigentlichen, sprungartigen Lastumschaltung. Zur Betätigung dieses Laststufenschalters ist ein  On-load tap-changer with linearly arranged selector contacts became known. Above the selector contacts, so separated locally, are the respective voter contacts assigned to each phase fixed vacuum interrupters for the actual, sudden load switching. To operate this on-load tap-changer is a
Federenergiespeicher notwendig, der während seiner Aufzugsbewegung die Wählerkontakte betätigt, als auch die Vakuumschaltelemente durch seine sprungartige Abtriebsbewegung antreibt. Federenergiespeicher necessary that actuates the selector contacts during its elevator movement, as well as the vacuum switching elements driven by its sudden output movement.
Unabhängig vom konstruktiven Aufbau des Laststufenschalters, also mit rotierendem oder linear bewegbarem Kontaktsystem, bedarf es bei aus dem Stand der Technik bekanntenRegardless of the structural design of the on-load tap-changer, that is to say with a rotating or linearly movable contact system, what is known from the prior art is required
Laststufenschaltern eines Federenergiespeichers zum sprungartigen Umschalten mittels des Kontaktsystems. Aus dem Stand der Technik bekannte Kraftspeicher werden zu Beginn jeder Betätigung des Laststufenschalters von einer Antriebswelle aufgezogen, d. h. On-load tap changers of a spring energy storage for sudden switching by means of the contact system. Force accumulators known from the prior art are mounted by a drive shaft at the beginning of each actuation of the on-load tap changer, i. H.
gespannt. Die bekannten Kraftspeicher bestehen im Wesentlichen aus einem curious; excited. The known energy storage consist essentially of a
Aufzugsschlitten und einem Sprungschlitten, zwischen denen Kraftspeicherfedern als Energiespeicher angeordnet sind. Derartige Kraftspeicher sind beispielsweise der DE 198 55 860 C1 sowie der DE 28 06 282 B1 entnehmbar. Elevator carriage and a spring carriage, between which power storage springs as Energy storage are arranged. Such energy storage, for example, DE 198 55 860 C1 and DE 28 06 282 B1 can be removed.
Es wird eine anfängliche langsame Drehbewegung der Antriebswelle genutzt, um einen Aufzugsschlitten translatorisch aufzuziehen, um nachfolgend die wiederum translatorische Bewegung des Sprungschlittens in eine rotatorische Hauptbewegung der Abtriebswelle und in eine damit verbundene eigentliche Kontaktbetätigung zu überführen. Diese aufwändige Wandlung einer Drehbewegung in eine translatorische Bewegung und wieder zurück in eine Drehbewegung erfordert einen hohen Platzbedarf der Kraftspeicherkonstruktion innerhalb des Laststufenschalters und zudem eine Vielzahl komplexer einzelner Baugruppen. It is used an initial slow rotational movement of the drive shaft to translate a lift carriage to subsequently convert the turn translational movement of the jump carriage in a rotational main motion of the output shaft and in an associated actual contact actuation. This complex conversion of a rotary movement into a translational movement and back into a rotary motion requires a large space requirement of the force storage structure within the on-load tap-changer and also a large number of complex individual assemblies.
Aufgabe der vorliegenden Erfindung ist es daher, einen Laststufenschalter anzugeben, der auf die aufwändige Konstruktion eines Kraftspeichers verzichtet und damit einen deutlich vereinfachten konstruktiven Aufbau bei gleichzeitig erhöhter Betriebssicherheit bietet. Object of the present invention is therefore to provide an on-load tap-changer, which dispenses with the complex construction of a force accumulator and thus provides a significantly simplified structural design while increasing operational safety.
Diese Aufgabe wird durch einen Laststufenschalter zur unterbrechungslosen Umschaltung zwischen verschiedenen Wicklungsanzapfungen eines Stufentransformators mit den Merkmalen des ersten Patentanspruches gelöst. Die Unteransprüche betreffen dabei besonders vorteilhafte Weiterbildungen der Erfindung. This object is achieved by an on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer having the features of the first claim. The subclaims relate to particularly advantageous developments of the invention.
Die allgemeine erfinderische Idee besteht darin, sowohl die Wählerkontakteinheit, als auch die Schaltmittel zur unterbrechungslosen Lastumschaltung mittels eines gemeinsamen Motorantriebes ohne Zwischenschaltung eines Energiespeichers zu betätigen. Nach einer bevorzugten Ausführungsform sind die Vakuumschaltröhren direkt an einem Gleitschlitten der jeweiligen Wählerkontakteinheit angeordnet und der Motorantrieb treibt mittels eines Winkelgetriebes eine zentrale Gewindespindel an, die mit mehreren The general inventive idea is to operate both the selector contact unit, as well as the switching means for uninterrupted load switching by means of a common motor drive without the interposition of an energy storage. According to a preferred embodiment, the vacuum interrupters are arranged directly on a sliding carriage of the respective selector contact unit and the motor drive drives by means of an angular gear on a central threaded spindle, which with several
Gleitschlitten in Wirkverbindung steht, wobei jeder Gleitschlitten eine Spindelmutter aufweist und die Gewindespindel mit der Spindelmutter eines jeden Gleitschlittens zusammenwirkt und die Drehbewegung in eine synchrone Längsverschiebung der mehreren Gleitschlitten umwandelt, derart, dass dadurch sowohl die beweglichen Wählerkontakte als auch die Vakuumschaltröhren betätig bar sind. Sliding slide is operatively connected, wherein each sliding carriage has a spindle nut and the threaded spindle cooperates with the spindle nut of each slide and converts the rotary motion into a synchronous longitudinal displacement of the plurality of slides so that thereby both the movable selector contacts and the vacuum interrupters are actu bar.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung weist der According to another preferred embodiment of the invention, the
Laststufenschalter ein an der Unterseite des Transformatordeckels befestigtes On-load tap-changer a fixed to the underside of the transformer cover
Getriebemodul auf, das mit dem an der gegenüberliegenden Außenseite des Transformatordeckels angeordneten Motorantrieb zusammenwirkt. Das Getriebemodul weist hierfür ein flanschartiges Dichtmodul auf, das direkt an der Unterseite des Gear module on, which with the on the opposite outside of the Transformer lid arranged motor drive cooperates. The gear module has for this purpose a flange-like sealing module, which is located directly at the bottom of the
Transformatordeckels angeordnet ist und mit dem Motorantrieb lösbar verbunden, insbesondere verschraubt, ist. An dem Getriebemodul ist zudem der gesamte Transformer cover is arranged and releasably connected to the motor drive, in particular screwed, is. On the transmission module is also the entire
Lastumschalter befestigt. Damit hat das Getriebemodul sowohl die Aufgabe, den Diverter switch attached. Thus, the gear module has both the task, the
Laststufenschalter zu halten, als auch mittels des Dichtmoduls gegenüber der Außenseite des Transformators abzudichten. Verwindungen des Transformatordeckels beim Transport des Trafos werden somit nicht an den Laststufenschalter übertragen. Zudem kann damit ein Anschlussflansch mit überfräster Dichtfläche am Transformatordeckel entfallen. Darüber hinaus bietet diese Art der vorgeschlagenen Befestigung eine für den Transformatorbauer einfache Montage des Laststufenschalters innerhalb des Transformatorkessels.  To keep on-load tap-changer, as well as by means of the sealing module to seal against the outside of the transformer. Twists of the transformer cover during transport of the transformer are thus not transmitted to the on-load tap-changer. In addition, a connection flange with overfilled sealing surface on the transformer cover can be dispensed with. In addition, this type of proposed attachment provides a simple for the transformer manufacturer mounting the on-load tap-changer within the transformer tank.
Nach einer wiederum weiteren Ausführungsform der Erfindung werden die beweglichen Wählerkontakte jeweils in einem Kontaktträger aufgenommen und wirken mit an einer Trägerplatte angeordneten festen Wählerkontakten zusammen, derart, dass die einzelnen festen Wählerkontakte durch eine Längsverschiebung der beweglichen Wählerkontakte samt Gleitschlitten, also der Wählerkontakteinheit, entlang der Führungsstange beschaltbar sind. Durch die Hin- und/oder Herbewegung der Wählerkontakteinheit werden die einzelnen festen Wählerkontakte beschaltet und damit der Regelbereich des Laststufenschalters durchlaufen. According to yet another embodiment of the invention, the movable selector contacts are each received in a contact carrier and cooperate with arranged on a support plate fixed selector contacts, such that the individual fixed selector contacts by a longitudinal displacement of the movable selector contacts together with slide, so the selector contact unit, along the guide rod are connectable. By the back and forth movement of the selector contact unit, the individual fixed selector contacts are connected and thus go through the control range of the on-load tap-changer.
