Description

Stufenschalter  step switch
Die Erfindung betrifft einen Stufenschalter zur unterbrechungslosen Umschaltung zwischen Wicklungsanzapfungen eines Stufentransformators. The invention relates to a tap changer for uninterrupted switching between winding taps of a tapped transformer.
In der Regel ist seitlich außen am Transformatorenkessel des Stufentransformators oder in dessen unmittelbarer Nähe ein Motorantrieb vorgesehen, der einen Antriebsmotor und weitere Bauteile aufweist und über ein Antriebsgestänge mit dem Kopf des in den In general, a motor drive is provided laterally outside the transformer tank of the tapped transformer or in the immediate vicinity, which has a drive motor and other components and a drive rod with the head of the in the
Transformatorenkessel eingebauten Stufenschalters in Verbindung steht und damit bei jeder Umschaltung den Stufenschalter motorisch betätigt. Ein typischer Motorantrieb ist Transformer boiler built-in tap changer is connected and thus the stepper switch motor operated with each change. A typical engine drive is
beispielsweise aus der WO 01/92978 A1 bekannt. Er beinhaltet einen Antriebsmotor, ein Lastgetriebe, ein Steuergetriebe, Überwachungs- und Anzeigeelemente, z. B. eine for example, from WO 01/92978 A1 known. It includes a drive motor, a load gear, a control gear, monitoring and display elements, eg. Legs
Stellungsanzeige. Position indicator.
Bei einer derartigen Betätigung eines Stufenschalters durch einen dezentral angeordneten Motorantrieb muss der Antriebszug, d. h. Antriebswellen, Winkeltrieb u. a., individuell an die jeweiligen räumlichen Verhältnisse am Transformator sowie am Stufenschalterkopf angepasst werden. In such an operation of a tap changer by a decentralized motor drive, the drive train, d. H. Drive shafts, angle drive u. a., Individually adapted to the respective spatial conditions on the transformer and the tap changer head.
Der betätigende Motorantrieb selbst muss ebenfalls auf den jeweiligen Stufenschalter, mit dem er zusammenwirken soll, abgestimmt sein. Insbesondere die Zahl der einstellbaren Spannungsstufen, die Zahl der Umdrehungen der Antriebswelle pro Umschaltung und die Art der Stellungsanzeige müssen individuell an den entsprechenden Stufenschalter angepasst werden. The actuating motor drive itself must also be matched to the respective tap changer with which it is intended to interact. In particular, the number of adjustable voltage levels, the number of revolutions of the drive shaft per switching and the type of position indicator must be individually adapted to the corresponding tap changer.
Aus der DE-OS 24 10 641 ist es weiterhin bereits bekannt, eine Antriebseinheit, bestehend aus einem Asynchronmotor oder Gleichstrommotor mit stirnseitig angebautem Leistungsund Hilfsgetriebe, unmittelbar auf dem Transformatordeckel am Aufhängeflansch des Stufenschalters zu befestigen. Dabei kann das Wellenende des Leistungsgetriebes der Antriebseinheit auch direkt oder über eine Wellenführung mit der Antriebswelle des From DE-OS 24 10 641 it is also already known to attach a drive unit consisting of an asynchronous motor or DC motor with frontally mounted power and auxiliary gearbox, directly on the transformer cover on suspension flange of the tap changer. In this case, the shaft end of the power transmission of the drive unit also directly or via a shaft guide with the drive shaft of the
Stufenschalters durch eine Kupplung verbunden werden. Damit ist eine Übertragung der Drehbewegung des Leistungsgetriebes auf den eigentlichen Stufenschalter möglich. Zwar wird bei dieser bekannten Lösung ein separates Antriebsgestänge mit Winkeltrieb entlang der Außenwandung des Transformatorenkessels vermieden, aber dennoch ist eine Anpassung und räumliche Zuordnung der Antriebseinheit bzw. des Antriebsmotors mittels der beschriebenen Kupplung an den darunter befindlichen Stufenschalter erforderlich. Tap changer to be connected by a coupling. For a transmission of the rotational movement of the power transmission to the actual tap changer is possible. Although a separate drive linkage with angular drive along the outer wall of the transformer tank is avoided in this known solution, but still an adaptation and spatial allocation of the drive unit or the drive motor by means of the described coupling to the underlying step switch is required.
Insbesondere zur Montage der Antriebseinheit ist eine genaue Positionierung relativ zurIn particular, for mounting the drive unit is a precise positioning relative to
Antriebswelle des Stufenschalter unabdingbar, damit es durch unerwünschtes Nichtfluchten von Wellenende des Leistungsgetriebes einerseits und Antriebswelle des Stufenschalters andererseits nicht zu Funktionsstörungen kommen kann. Ferner erfordert die bekannte Lösung, wie bereits erwähnt, in jedem Fall eine separate Kupplung und weist ein separates Hilfsgetriebe auf. Drive shaft of the tap changer indispensable, so it may not malfunction due to unwanted non-alignment of the shaft end of the power transmission on the one hand and drive shaft of the tap changer on the other hand. Furthermore, the known solution, as already mentioned, in each case requires a separate clutch and has a separate auxiliary transmission.
Auch diese bekannte Anordnung ist mithin kompliziert im Aufbau und erfordert eine kundenseitige Anpassung der einzelnen Baugruppen aneinander und genaue Positionierung zueinander. Also, this known arrangement is therefore complicated in structure and requires a customer-side adaptation of the individual modules to each other and accurate positioning each other.
Aufgabe der Erfindung ist es, einen kompakten, preisgünstigen Stufenschalter anzugeben, der diese Nachteile nicht aufweist. The object of the invention is to provide a compact, low-cost tap changer, which does not have these disadvantages.

Above the tap changer head 1 is the actual compact motor drive, according to the invention as an integral part of the tap changer, comprising a geared motor 3. This geared motor 3 is designed as a compact assembly and consists of the actual electric motor 3.1 and a gear assembly 3.2. The

Zwar ist es aus der WO 2007/065499 A1 bereits bekannt, eine Although it is already known from WO 2007/065499 A1, a
Schaltüberwachungseinrichtung mit einer Nockenscheibe mit horizontal geteilter Kontur vorzusehen, die dort beschriebene Vorrichtung bezieht sich jedoch auf einen leistungslos schaltenden Umsteller, der überhaupt keinen Motorantrieb aufweist, zudem ist sie oberhalb einer oberen Getriebestufe in einem separaten Gehäuse angeordnet, kann also nicht mit dem Stellungsmelderad 15 der Erfindung verglichen werden. Switch monitoring device with a cam to provide horizontally split contour, but the device described therein refers to a powerless switching diverter, which has no motor drive at all, also it is above an upper gear stage arranged in a separate housing, so it can not with the position indicator wheel 15 of Invention are compared.
Auf dem Stellungsmelderad 15 sind erfindungsgemäß weiterhin auf einem horizontalen Teilkreis feste Stellungmeldekontakte 16 angeordnet, von denen nicht alle mit On the position indicator wheel 15 according to the invention further fixed position signaling contacts 16 are arranged on a horizontal pitch circle, of which not all with

Bei der Erfindung hingegen sind die Funktionalitäten von Schaltüberwachung einerseits und Such a sliding contact per se as part of a separate motor drive is already known from WO 98/36435. In contrast to the invention, however, it acts together in the known solution with fixed contacts on a stationary, separate board.
