Description

Die Erfindung betrifft ein Verfahren und Vorrichtung zur Montage eines Transformators, wobei ein Transformatorkern des Transformators in einer Aufnahme anordbar ist und um den Transformatorkern eine Wicklung angeordnet wird.The invention relates to a method and apparatus for mounting a transformer, wherein a transformer core of the transformer can be arranged in a receptacle and a winding is arranged around the transformer core.

Die Herstellung eines Hochspannungs- beziehungsweise eine Höchstspannungstransformators erfordert aufgrund der einzuhaltenden mechanischen und elektrischen Rahmenbedingungen eine sehr präzise Fertigung. So werden die Transformatorkerne bezüglich der oberen und unteren Joche auf einer entsprechenden Schwenkbühne angeordnet, die für zum Teil mehr als hundert Tonnen Last ausgelegt sind. Zur Vermeidung von Wirbelstromverlusten werden die Transformatorkerne auf diese Aufnahme durch geschichtete Bleche aufgebaut. Nach Fertigstellung der so konzipierten Transformatorkerne und eines entsprechenden oberen beziehungsweise unteren Joches werden herkömmlicherweise anschließend die Wicklungen um die so aufgebauten Transformatorkerne angeordnet. Anschließend wird das noch fehlende Joch in die Transformatorkerne eingeschichtet und fixiert.The production of a high-voltage or a high-voltage transformer requires due to the mechanical and electrical conditions to be complied with a very precise production. Thus, the transformer cores are arranged with respect to the upper and lower yokes on a corresponding pivoting platform, which are designed for sometimes more than a hundred tons of load. To avoid eddy current losses, the transformer cores are built up on this receptacle by layered sheets. After completion of the so-designed transformer cores and a corresponding upper or lower yoke, the windings are conventionally then arranged around the so-constructed transformer cores. Then the missing yoke is layered into the transformer cores and fixed.

Die Ausleitungen dieser so konzipierten Wicklungen sind teilweise als Teilwicklungen ausgeformt und werden bei Wechselspannungstransformatoren unmittelbar an der Ausleitung verbunden.The discharges of these windings designed in this way are partially formed as partial windings and are connected directly to the outlet in the case of AC voltage transformers.

Im Gegensatz hierzu werden bei Gleichstromtransformatoren großer Leistung die jeweiligen Wicklungen der Schenkel unmittelbar miteinander verbunden. Insbesondere bei Hochspannungsbeziehungsweise Höchstspannungsanwendungen wird mittels einer entsprechenden Ventilleitungsausführung elektrisch verbunden. Aufgrund der sehr hohen Spannungsbereiche und der damit verbundenen Isolationsproblematik in Relation zu den Wicklungen beziehungsweise zu dem Transformatorkessel benötigt die Ventilwicklung bei der derzeitigen Fertigungstechnologie von HGÜ-Transformatoren einen großen Raumbereich am bzw. innerhalb des Transformators.In contrast, in DC power transformers of high power, the respective windings of the legs are directly connected to each other. In particular, in high voltage or high voltage applications by means of a corresponding valve line design electrically connected. Due to the very high voltage ranges and the associated insulation problems in relation to the windings or to the transformer tank, the valve winding in the current production technology of HVDC transformers requires a large space area on or within the transformer.

So zeigt beispielsweise die G 9307081 eine flüssigkeitsgekühlte Ventildrossel, bei der in aufwändiger Art und Weise die Ventilverbindungen der Wicklungen beschrieben sind.For example, G 9307081 shows a liquid-cooled valve throttle in which the valve connections of the windings are described in a complex manner.

Des Weiteren beschreibt die EP 1 997 117 B1 ein Verbindungselement für eine elektrische Abschirmungsanordnung. Gemäß der dortigen Erfindung kann das Isolationssystem um die Ventilleitungsausführung in modularer Bauweise konzipiert werden. Hierdurch ist eine schnelle und einfache Montage der Isolation beziehungsweise der gesamten Ventilausleitung zwischen den einzelnen Wicklungen möglich.Furthermore, the describes EP 1 997 117 B1 a connection element for an electrical shielding arrangement. According to the local invention, the isolation system can be designed around the valve line design in a modular design. As a result, a quick and easy installation of the insulation or the entire valve outlet between the individual windings is possible.

Nachteilig an allen Lösungen im Stand der Technik ist jedoch, dass die Ventilausleitungen seitlich an den Wicklungen vorbeigeführt werden. Dies ist daher notwendig, da nach der bisherigen Fertigungstechnik die Wicklungen auf die Transformatorkerne aufgesetzt und anschließend sofort fixiert werden. Danach werden die entsprechenden elektrischen Verbindungen der Wicklungen untereinander mittels der Ventilleitungsführung vorgenommen und können aufgrund des nicht vorhandenen Zwischenraums zwischen den Wicklungen nicht unmittelbar dort montiert und fixiert werden. JP 2001 167961 A offenbart die Oberbegriffe der Ansprüche 1 und 8, jedoch werden dort in den Fig. 11 bis 13 lediglich einzelne Wicklungen 14 durch die Hebebühne 1 angehoben und seitlich verschoben. Ähnliches offenbart JP 2003 086429 A in seiner Fig. 3 und JP 5 062847 A in seiner Fig. 7. Aufgabe der vorliegenden Erfindung ist es daher, die Bereitstellung einer Vorrichtung eines Verfahrens mittels derer eine Leitungsverbindung zwischen zwei Wicklungen eines Transformators, insbesondere eines Hochspannungsgleichstromübertragung (HGÜ) -Transformators, einfach, platzsparend, sowie elektrisch und mechanisch sicher gewährleistet werden kann. Die Aufgabe wird gelöst mit einer Vorrichtung gemäß den Merkmalen des Patentanspruchs 1.A disadvantage of all solutions in the prior art, however, is that the valve discharges are guided past the windings laterally. This is therefore necessary because according to the previous production technology, the windings are placed on the transformer cores and then fixed immediately. Thereafter, the corresponding electrical connections of the windings are made with each other by means of the valve line guide and can not be mounted and fixed directly there due to the lack of space between the windings. JP 2001 167961 A discloses the preambles of claims 1 and 8, but there are in Figs. 11 to 13 only single windings 14 lifted by the lift 1 and laterally displaced. Similar disclosed JP 2003 086429 A in its Fig. 3 and JP 5 062847 A in its Fig. 7. The object of the present invention is therefore to provide a device of a method by means of which a line connection between two windings of a transformer, In particular, a high voltage direct current (HVDC) transformer, simple, space-saving, as well as electrically and mechanically safe can be guaranteed. The object is achieved with a device according to the features of patent claim 1.

Des Weiteren wird die Aufgabe gelöst durch ein Verfahren gemäß den Merkmalen des Patentanspruchs 8.Furthermore, the object is achieved by a method according to the features of patent claim 8.

Erfindungsgemäß ist eine Vorrichtung zur Montage eines Transformators vorgesehen, bei der die Aufnahme innerhalb einer Hebebühne anordbar ist, die Hebebühne Verstellelemente aufweist, wobei die Verstellelemente relativ zueinander verschiebbar sind. Durch die Erweiterung der bisher bekannten Aufnahme für die Transformatorkerne, die nach derzeitigem Stand der Technik für die Schichtung der Transformatorkerne in die Horizontale und die Senkrechte schwenkbar sind, in Kombination mit einer Hebebühne, die Verstellelemente aufweist, ist es möglich, den Transformator in einer modularen Bauweise mit einer Vielzahl von Fertigungsschritten herzustellen. Mittels der Verstellelemente ist es möglich, die Wicklungen um den Transformatorkern anzuordnen und bei Bedarf wieder anzuheben.According to the invention a device for mounting a transformer is provided, wherein the receptacle can be arranged within a lift, the lift comprises adjusting elements, wherein the adjusting elements are displaceable relative to each other. By expanding the previously known receptacle for the transformer cores, which are pivotable in the current state of the art for the stratification of the transformer cores in the horizontal and vertical, in combination with a lift, which has adjusting elements, it is possible to transform the transformer in a modular Build with a variety of manufacturing steps. By means of the adjusting elements, it is possible to arrange the windings around the transformer core and to raise it again if necessary.

Des Weiteren ist durch die Verschiebbarkeit der Verstellelemente entlang der Hebebühne gewährleistet, dass die Wicklungen nicht nur angehoben und abgesenkt werden können, sondern auch relativ zueinander bewegbar sind. So ist es beispielsweise möglich, eine Wicklung um einen ersten Transformatorkern unmittelbar anzuordnen und zu fixieren sowie eine zweite Wicklung, die von einem Transformatorkern abgehoben wurde, mit einem vergrößerten Zwischenraum zur ersten zu positionieren. Mittels der Hebebühne ist dann für einen Fertigungsmitarbeiter die Möglichkeit gegeben, aufgrund des vergrößerten Zwischenraums zwischen der ersten und der zweiten Wicklung hier entsprechende Arbeiten vorzunehmen.Furthermore, it is ensured by the displaceability of the adjusting elements along the lifting platform that the windings can not only be raised and lowered but are also movable relative to each other. Thus, for example, it is possible to directly arrange and fix a winding around a first transformer core and to position a second winding, which has been lifted off a transformer core, with an enlarged gap to the first one. By means of the lift is then for a production worker given the opportunity to do due to the increased gap between the first and the second winding here corresponding work.

Vorteilhafterweise ist die Hebebühne mit den Verstellelementen relativ zur Aufnahme positionierbar. Es ist vorteilhaft, dass die Aufnahme eigenständig bewegbar ist. Dies wird insbesondere mittels entsprechender Radaufhängungen oder Luftkissen an der Aufnahme gewährleistet. So können die entsprechenden Transformatorkerne eigenständig mittels einer Aufnahme geschichtet und anschließend an andere Stellen verbracht werden. Mit der Fertigstellung eines entsprechenden Transformators auf einer Aufnahme kann dann der Transformatorkern - ohne ein oberes Joch - dann innerhalb der Hebebühne angeordnet und in einem nachfolgenden Arbeitsschritt dann die Wicklungen auf dem Transformatorkern angeordnet werden.Advantageously, the lift with the adjusting elements can be positioned relative to the recording. It is advantageous that the recording is independently movable. This is ensured in particular by means of appropriate suspension or air cushion on the recording. Thus, the corresponding transformer cores can be layered independently by means of a recording and then moved to other locations. With the completion of a corresponding transformer on a recording then the transformer core - without an upper yoke - then arranged within the lift and then the windings are arranged on the transformer core in a subsequent step.

In einer vorteilhaften Ausgestaltung der Vorrichtung ist vorgesehen, dass die Verstellelemente auf einem entlang der Hebebühne verstellbaren Schlitten angeordnet sind. Insbesondere jeweils zwei Verstellelemente auf zwei sich gegenüber liegenden Seiten bilden vorteilhafterweise einen Schlitten, der eine Positionierung um einen Transformatorkern erlaubt und damit eine Anhebung einer dem jeweiligen Transformatorkern zugeordneten Wicklung ermöglicht. Dabei sind insbesondere die Verstellelemente bezüglich der Lage des Transformatorkerns positionierbar. Die Ansteuerung der Verstellelemente und die Hebebühne werden koordiniert von einer Steuereinheit.In an advantageous embodiment of the device is provided that the adjusting elements are arranged on a carriage adjustable along the lift. In particular, in each case two adjusting elements on two opposite sides advantageously form a carriage which allows positioning about a transformer core and thus allows an increase of a winding associated with the respective transformer core. In particular, the adjusting elements can be positioned relative to the position of the transformer core. The control of the adjustment and the lift are coordinated by a control unit.

Erfindungsgemäß ist ebenfalls ein Verfahren zur Herstellung eines Transformators vorgesehen, wobei mittels einer Vorrichtung zur Montage des Transformators der Transformatorkern in einer Aufnahme angeordnet wird und die Aufnahme innerhalb der Hebebühne anordbar ist, wobei die Hebebühne Verstellelemente aufweist und die Verstellelemente relativ zueinander verschiebbar sind. Vorteilhaft wird eine Wicklung mittels der Vorrichtung um einen Transformatorkern angeordnet und anschließend wieder vom Transformatorkern abgehoben, wobei an der angehobenen Wicklung eine Leitungsausführung angebracht wird. Mittels der oben genannten Vorrichtung ist es gemäß dem erfindungsgemäßen Verfahren möglich, eine Wicklung auf einem Transformatorkern vorzupositionieren und anschließend wieder vom Transformatorkern abzuheben.According to the invention, a method for producing a transformer is also provided, wherein by means of a device for mounting the transformer, the transformer core is arranged in a receptacle and the receptacle can be arranged within the lift, wherein the lift adjusting elements and the adjusting elements are displaceable relative to each other. Advantageously, a winding is arranged by means of the device around a transformer core and then lifted again from the transformer core, wherein a line design is attached to the raised winding. By means of the above-mentioned device, according to the method of the invention, it is possible to pre-position a winding on a transformer core and then lift it off the transformer core again.

In diesem zweiten Arbeitsschritt ist es anschließend möglich, die entsprechende Leitungsführung nunmehr zwischen den einzelnen Wicklungen anzuordnen. Dies wird dadurch möglich, dass mittels der entsprechenden Verstellelemente beziehungsweise der einem Schlitten zugeordneten Verstellelemente die Wicklung relativ zum Transformatorkern nicht nur angehoben und abgesenkt werden kann, sondern ebenfalls ein seitlicher Versatz möglich ist. Hierdurch ergibt sich die Möglichkeit, zwischen zwei Wicklungen einen Zwischenraum zu erzeugen, der zu einer Anbringung der Ventilleitungsausführung geeignet ist. Weiterhin ist es möglich, die entsprechenden Ventilausleitungen unmittelbar zwischen den Wicklungen anzubringen und nicht, wie im Stand der Technik, an den bereits fixierten Wicklungen seitlich vorbeigeführt werden muss.In this second step, it is then possible to arrange the corresponding wiring now between the individual windings. This is possible because by means of the corresponding adjusting elements or the adjusting elements associated with a slide, the winding can not only be raised and lowered relative to the transformer core, but also a lateral offset is possible. This results in the possibility between two windings to create a gap which is suitable for mounting the valve line design. Furthermore, it is possible to install the corresponding valve outlets directly between the windings and not, as in the prior art, to be guided laterally past the already fixed windings.

Dies ergibt nunmehr den Vorteil, dass die entsprechenden Baugrößen aufgrund der unmittelbar zwischen den Wicklungen angeordneten Ventilverbindungen verkleinert werden kann.This now gives the advantage that the corresponding sizes can be reduced due to the valve connections arranged directly between the windings.

Mittels des vorgenannten Verfahrens kann somit sukzessiv jeweils zwei Wicklungen mittels eines vergrößerten Zwischenraums verbunden werden. Somit können nach der jeweiligen elektrischen Verbindung aller Wicklungen mit der Ventilausleitungen die Wicklungen wieder auf den ursprünglichen Abstand relativ zueinander und damit auf die jeweiligen Transformatorkerne abgesenkt werden.By means of the above-mentioned method, two windings can thus be successively produced by means of an enlarged intermediate space get connected. Thus, after the respective electrical connection of all windings with the valve outlet, the windings can be lowered back to the original distance relative to each other and thus to the respective transformer cores.

Diese Form der Montage bietet sich insbesondere für HGÜ-Transformatoren oder Hochspannungsgleichstromdrosseln an. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. Die Erfindung wird mittels der nachfolgenden Zeichnungen eingehend erläutert. Es zeigen die

Auf der Aufnahme ist ein 3/2-Kerntyp des Transformatorkerns 6 ohne oberes Joch gezeigt. Um die 3 Transformatorkerne 6 sind jeweils bereits die Wicklungen 5 angeordnet. Verstellelemente 7 können unterhalb der Wicklungen 5 angeordnet werden, so dass ein Anheben der Wicklungen 5 relativ zum Transformatorkern möglich ist. Vorteilhafterweise sind die Verstellelemente 7 bezüglich einer Wicklung 5 jeweils zu einem Schlitten 8 zusammengefasst.The Fig. 2 shows a plan view of the device 1, wherein within the lift 2, the receptacle 3 is arranged. On the picture, a 3/2 core type of the transformer core 6 without the upper yoke is shown. The windings 5 are already arranged around the 3 transformer cores 6. Adjusting elements 7 can be arranged below the windings 5, so that a lifting of the windings 5 relative to the transformer core is possible. Advantageously, the adjusting elements 7 are combined with respect to a winding 5 in each case to form a carriage 8.

Die Fig. 3 zeigt eine Seitenansicht der Vorrichtung 1, wobei innerhalb der Hebebühne 2 die Aufnahme 3 eingeschoben ist. Im gezeigten Beispiel der Fig. 3 ist um den Transformatorkern 6 keine Wicklung angeordnet und die an der Hebebühne 2 angebrachten Verstellelemente 7 ragen in den Innenraum.The Fig. 3 shows a side view of the device 1, wherein within the lift 2, the receptacle 3 is inserted.

In this state, all three windings can be lowered together or placed individually on the transformer core 6 so that a space is created between two windings 5.

In den so ausgebildeten Zwischenraum kann dann eine entsprechende Ventilausleitung 11 (nicht dargestellt) montiert werden. Anschließend werden die Wicklungen 5 wieder auf den ursprünglichen Abstand mittels der Verstellelemente 7 gebracht und können gemeinsam dann auf die Transformatorkerne 6 abgesenkt werden.In the space thus formed then a corresponding valve outlet 11 (not shown) can be mounted. Subsequently, the windings 5 are brought back to the original distance by means of the adjusting elements 7 and can then be lowered together to the transformer cores 6.

Die Fig. 6 zeigt wiederum eine Aufsicht der Vorrichtung 1, wobei im Vergleich zur Fig. 2 nunmehr das Ausschwenken der äußerst linken Wicklung 5 relativ zur mittleren Wicklung 5 sichtbar ist. Im gezeigten Beispiel der Fig. 6 ist nunmehr der linke Transformatorkern 6 sichtbar. In dem so gebildeten Zwischenraum kann nunmehr eine Ventilleitung 11 angebracht werden. Zwischen der mittleren Wicklung 5 und der rechten Wicklung 5 ist bereits eine Ventilausleitung 11 im gezeigten Beispiel der Fig. 6 montiert. Mit der Anbringung der Ventilverbindung 11 zwischen der linken und der mittleren Wicklung 5 kann anschließend die linke Wicklung 5 wieder auf die ursprüngliche Position mittels der Verstellelemente 7 zurückgeschoben werden.
