Abstract
Description
Die Erfindung betrifft eine Kontaktanordnung an einem Vorwähler eines Stufenschalters.The invention relates to a contact arrangement on a selection of a tap changer.
Bei Stufenschaltern ist es seit langem üblich, zur Vergrößerung des jeweils möglichen Einstellbereiches einen Vorwähler vorzusehen. Dieser dient entweder als Grobwähler zur Zur- und Gegenschaltung der Stufenwicklung oder als Wender zur Umlenkung der Stufenwicklung an den Anfang oder an das Ende der Grobstufe. Ein solcher bekannter Vorwähler besteht üblicherweise für jede Phase aus drei festen Vorwählerkontakten, wobei jeweils einer der beiden festen Kontakte, der "Plus"-Kontakt oder der "Minus"-Kontakt, mit dem dritten festen Kontakt, dem 0-Kontakt, verbunden ist.With step switches, it has long been common to enlarge what is possible Setting range to provide a selection. This serves either as a coarse selector for the supply and Counter-connection of the step winding or as a turner for deflecting the step winding to the Beginning or end of the rough level. Such a known selection usually exists for each phase from three fixed selector contacts, one of the two fixed contacts, the "Plus" contact or the "minus" contact connected to the third fixed contact, the 0 contact is.
Aus den bulgarischen Firmenschriften "On-load Tap Changer Type RS12" und "On-load Tap Changer Type 16" ist ein Vorwähler eines Stufenschalters bekannt, der sich außerhalb des Isolierstoffzylinders des Stufenschalters in dessen Längsrichtung erstreckt. Die festen Vorwählerkontakte sind in einer Linie angeordnet, weisen eine kugelige Kontaktfläche auf und werden durch eine in Längsrichtung verschiebbare Schaltstange mit einer Kontaktbrücke auf die oben beschriebene Weise beschaltet.From the Bulgarian company publications "On-load Tap Changer Type RS12" and "On-load Tap Changer Type 16 "is a selection of a tap changer, which is located outside the insulating cylinder of the tap changer extends in its longitudinal direction. The fixed selection contacts are in one Arranged line, have a spherical contact surface and are characterized by a in the longitudinal direction Slidable shift rod connected with a contact bridge in the manner described above.
Aus der gattungs bildenden DE 93 08 424 U1 ist weiterhin ein Vorwähler bekannt, der als Mehrfach-Grobwähler ausgebildet ist und ein separates Gehäuse aufweist. Die Betätigung dieses Vorwählers erfolgt hierbei durch eine drehbare Schaltwelle. Die festen Vorwählerkontakte weisen hierbei ebenfalls jeweils eine ballige Kontaktfläche auf, die mittels an der drehbaren Schaltwelle angeordneter und mit dieser verschwenkbarer beweglicher Kontakte beschaltbar sind.From the generic DE 93 08 424 U1 a selection is also known, which is a multiple coarse selector is formed and has a separate housing. This selection is activated here through a rotatable selector shaft. The fixed selector contacts also each have one spherical contact surface, which is arranged on the rotatable control shaft and with this pivotable movable contacts can be connected.
Schließlich ist in der nicht vorveröffentlichten DE 198 36 463 ein Vorwähler vorgeschlagen worden, der als vom Stufenschalter getrennte Baugruppe in einem separaten Isolierstoffgehäuse untergebracht ist, in dessen Inneren eine längsverschiebbare Schaltstange verläuft. Die festen Vorwählerkontakte sind hierbei kreisförmig ausgebildet und konzentrisch um die Schaltstange herum in unterschiedlichen Ebenen im Inneren des Isolierstoffgehäuses angeordnet. Die Montage solcher kreisförmiger, konzentrischer fester Vorwählerkontakte in das Innere eines solchen rohrförmigen Isolierstoffgehäuses hat sich jedoch als außerordentlich schwierig erwiesen. Dabei ist zu berücksichtigen, daß aus Spannungsgründen das den gesamten Vorwähler tragende rohrförmige Isolierstoffgehäuse einteilig ausgebildet ist und zudem keine großen Öffnungen, d. h. Unterbrechungen des Isoliermaterials, aufweisen sollte, andererseits aber solche Öffnungen erforderlich sind, um die festen Vorwählerkontakte ins Innere zu bringen und dort zu befestigen.Finally, a selection has been proposed in the unpublished DE 198 36 463, the as a separate module from the tap changer in a separate insulating housing is housed, in the interior of which a longitudinally displaceable shift rod runs. The firm Selector contacts are circular and concentric around the selector rod arranged in different levels inside the insulating material housing. The assembly of such circular, concentric fixed selection contacts into the interior of such a tubular Isolierstoffgehäuses has proven to be extremely difficult. It is too take into account that, for reasons of tension, the tubular bearing the entire selection Isolierstoffgehäuse is formed in one piece and also no large openings, i. H. Interruptions in the insulating material, but on the other hand such openings are required to bring the fixed selector contacts inside and secure them there.
Aufgabe der Erfindung ist es demnach, diese Mängel zu beseitigen und eine erfindungsgemäße Kontaktanordnung anzugeben, bei der ein kreisförmig ausgebildeter fester Vorwählerkontakt auf einfache Weise in einem rohrförmigen Isolierstoffgehäuse, das den Vorwähler aufnimmt, befestigbar ist. The object of the invention is therefore to eliminate these deficiencies and an inventive Specify contact arrangement, in which a circularly formed fixed selection contact easy to attach in a tubular insulating housing that houses the selection is.
Diese Aufgabe wird durch eine gattungsgemäße Kontaktanordnung mit den Merkmalen des ersten Patentanspruches gelöst. Die Unteransprüche betreffen besonders vorteilhafte Weiterbildungen der Erfindung.This object is achieved by a generic contact arrangement with the features of the first Claim resolved. The subclaims relate to particularly advantageous developments of the Invention.
Die erfindungsgemäße Kontaktanordnung weist eine Reihe von Vorteilen auf: Zum einen bildet der feste Vorwählerkontakt selbst in seiner Form eine ideale Elektrode und nutzt den verfügbaren Innendurchmesser des Isolierstoffzylinders, in dem er befestigt wird, optimal aus. Er ist von innen zu befestigen, indem er, wie später noch näher erläutert werden wird, in das Innere selbst eingeführt und derart montiert wird, daß seine Anschlußmittel durch entsprechende Bohrungen nach außen führen. Damit sind keine weiteren Öffnungen oder Aussparungen im Isoliermaterial erforderlich. Die gesamte Kontaktanordnung ist sowohl für senkrechten als auch waagerechten Anschluß außerhalb des Isolierstoffzylinders auf gleiche Weise geeignet. Weiterhin ist mit der erfindungsgemäßen Kontaktanordnung eine verdrehsichere und toleranzausgleichende Befestigung der festen Vorwählerkontakte ermöglicht, und schließlich ist auf einfache Weise die Befestigung zusätzlicher Abschirmungen und Schirmringe einschließlich Potentialanlenkung möglich.The contact arrangement according to the invention has a number of advantages: On the one hand, the fixed selector contact even in its shape an ideal electrode and uses the available one Optimal inside diameter of the insulating material cylinder in which it is attached. It is closed from the inside fasten by inserting it into the interior itself, as will be explained in more detail later, and is mounted in such a way that its connection means lead through corresponding holes to the outside. This means that no further openings or recesses in the insulating material are required. The whole Contact arrangement is for both vertical and horizontal connection outside the Insulating cylinder suitable in the same way. Furthermore, with the invention Contact arrangement a twist-proof and tolerance-compensating attachment of the fixed Selector contacts allows, and finally, the attachment is easy Shielding and shield rings including potential connection possible.

In den Figuren 1 bis 5 sind die erfindungsgemäße Kontaktanordnung insgesamt sowie in
verschiedenen Baugruppen bzw. Einzelteilen dargestellt. Ein rohrförmiges Isolierstoffgehäuse 1 weist
für jeden zu befestigenden festen Vorwählerkontakt eine Bohrung 11 auf. Aus Vereinfachungsgründen
ist jeweils nur eine dieser Bohrungen dargestellt. Die Bohrung 11 ist in Längsrichtung des
Isolierstoffgehäuses 1 nach oben um einen oberen Montageschlitz 12 und nach unten um einen
unteren Montageschlitz 13 erweitert, so daß sich insgesamt jeweils eine Öffnung mit der in Figur 3 im
Detail dargestellten Kontur ergibt. Der feste Vorwählerkontakt 2 weist den eigentlichen Kontaktring 21
auf, der sich im Inneren des Isolierstoffgehäuses konzentrisch um die nicht dargestellte Antriebswelle
herum erstreckt und der von den ebenfalls nicht dargestellten beweglichen Vorwählerkontakten bzw.-kontaktbrücken
beschaltbar ist. Jeder feste Vorwählerkontakt 2 weist weiterhin einen Kontaktschaft 22
auf, der durch die entsprechende Bohrung 11 des Isolierstoffgehäuses 1 nach außen führt. Durch
einen Anschlag 23, der als Elektrode ausgebildet ist, wird ein definiertes Anliegen des
Vorwählerkontaktes 2 an der Innenwand des Isolierstoffgehäuses 1 gewährleistet. Der Kontaktschaft
22 weist an seinem ansonsten zylindrischem Umfang zwei seitliche Arretierungsflächen 24, 25 auf,
deren Funktion weiter unten noch näher beschrieben wird. Im vorderen Bereich ist am Kontaktschaft
22 ein Gewinde 26 und am äußeren Ende eine Anschlußfläche 27 mit einer Anschlußbohrung 28
vorgesehen. Dort werden die entsprechenden elektrischen Anschlußleitungen, die zum jeweiligen
festen Vorwählerkontakt führen, befestigt. Die erfindungsgemäße Kontaktanordnung weist ferner ein
aus Isolierstoff bestehendes Positionierteil 3 auf. Dieses ist einzeln im Detail in Figur 4 dargestellt.
Das Positionierteil 3 besitzt eine obere Montageschlitzabdeckung 31 und eine untere
Montageschlitzabdeckung 32, die sich flügelartig erstrecken. Diese beiden
Montageschlitzabdeckungen 31, 32 korrespondieren in ihrer Form mit den bereits beschriebenen
Montageschlitzen 12, 13 an der entsprechenden Bohrung 11. Im übrigen weist das Positionierteil 3
eine äußere Kreiskontur 33 auf, die mit dem Durchmesser der Bohrung 11 korrespondiert. Ferner
besitzt es eine innere Kreiskontur 36, die mit dem Durchmesser des Kontaktschaftes 22
korrespondiert. An dieser inneren Kreiskontur 36 sind zwei seitliche Arretierungskonturen 37, 38
angeformt, die ihrerseits mit den beiden Arretierungsflächen 24, 25 korrespondieren. Im montierten
Zustand ist das Positionierteil in die Bohrung 11 sowie die Montageschlitze 12, 13 gesteckt und wirkt
gleichzeitig durch die zusammengehörigen Arretierungsflächen 24, 25 am festen Vorwählerkontakt 2
und die Arretierungskonturen 37, 38 als Verdrehsicherung für den festen Vorwählerkontakt. Am
Positionierteil 3 ist noch ein Anschlag 35 angeformt, der verhindert, daß dieses Teil in das Innere des
Isolierstoffgehäuses 1 durchrutschen kann. Auf dem nach außen ragenden Kontaktschaft 22 wird,
nachdem das Positionierteil 3 auf die beschriebene Weise aufgesteckt ist, noch ein Abschirmring 4
gesteckt; durch eine Befestigungsmutter 9 und noch dazwischen angeordnete Scheiben 5, 6, 7, 8 wird
die gesamte Anordnung befestigt, indem die Befestigungsmutter 9 auf dem Gewinde 26 festgezogen
wird. Es ist auch noch möglich, ohne zusätzliche Befestigungsmittel eine weitere Vorwähler-Abschirmung
mit zu befestigen, so wie dies in Figur 2 dargestellt ist.The contact arrangement according to the invention as a whole and in FIGS

a
In Figur 6 ist jeweils in mehreren Sequenzen die Montage eines festen Vorwählerkontaktes 2 gezeigt.
Es ist ersichtlich, daß die Kontakte mittels geeigneter, hier nicht dargestellter, Vorrichtungen,
Zugvorrichtungen etwa, im Inneren bis in den Bereich der entsprechenden Bohrung 11 mit den
Montageschlitzen 12, 13, an dem die Befestigung erfolgen soll, geschoben werden. Dort erfolgt ein
langsames Aufrichten des jeweiligen festen Vorwählerkontaktes 2, wobei der Kontaktschaft 22 mit der
angeformten Anschlußfläche 28 durch die aus der jeweiligen Bohrung 11 und den beiden
Montageschlitzen 12 oder 13 gebildete Kontur nach außen geschwenkt wird. Hat der
Vorwählerkontakt 2 seine endgültige Position erreicht, d. h., ist der Kontaktring 21 in horizontaler
Position, wird das Positionierteil 3 von außen aufgesteckt und damit die Verdrehsicherung mittels des
weiter oben ausführlich beschriebenen Zusammenwirkens von Arretierungsflächen 24, 25 und
Arretierungskonturen 37, 38 realisiert. Anschließend wird die gesamte Anordnung durch Aufdrehen
der Befestigungsmutter 9 auf das Gewinde 26, ggf. unter Zwischenlage weiterer Bauelemente,
befestigt - die Montage ist abgeschlossen.FIG. 6 shows the assembly of a fixed
Für die jeweiligen Arretierungsflächen 24, 25 und die damit zusammenwirkenden
Arretierungskonturen 37, 38 sind dabei vielfältige geometrische Ausbildungen möglich; die Anordnung
ist nicht auf die hier beschriebene seitliche Abflachung am Kontaktschaft 22 beschränkt.For the respective locking surfaces 24, 25 and the interacting with them

Das Positionierteil 3 ist in seiner Dicke zweckmäßigerweise derart bemessen, daß es der Dicke des
rohrförmigen isolierstoffgehäuses 1 entspricht, so daß es im montierten Zustand sich innen am
Anschlag 23 abstützt und vollständig in der Oberfläche des Isolierstoffgehäuses 1 verschwindet.The
Damit ist eine formschlüssige, verdrehsichere Arretierung des von innen montierten festen
Vorwählerkontaktes 2 gewährleistet: Er selbst ist durch die zusammenwirkenden korrespondierenden
Arretierungsflächen 24, 25 einerseits sowie Arretierungskonturen 37, 38 andererseits gegenüber dem
Positionierteil 3 fixiert. Dieses wiederum ist durch seine obere und untere Montageschlitzabdeckung
31, 32, die jeweils in den oberen und unteren Montageschlitz 12, 13 der entsprechenden Bohrung 11
eingreifen, gegenüber dem Isolierstoffgehäuse 1 fixiert. Durch das Aufbringen einer
Befestigungsmutter 9 von außen auf das Gewinde 26 erfolgt zusätzlich eine feste, kraftschlüssige
Verbindung.This is a positive, non-rotating locking of the fixed from the
In Figur 6 ist auch bereits gezeigt, daß die beschriebene Montage unabhängig davon möglich ist, ob
die entsprechende Anschlußfläche 27 im montierten Zustand waagerecht oder senkrecht angeordnet
sein soll. Im ersten Fall erfolgt die Montage in senkrechter Lage des Kontaktringes 21, und vor dem
Einstecken des Positionierteiles 3 muß der Kontaktschaft 22 von außen um 90 Grad gedreht werden.
Im zweiten Fall ist ein solches Verdrehen nicht erforderlich. In Figure 6 is also already shown that the assembly described is possible regardless of whether
