Description

Wicklung für einen Transformator Winding for a transformer
Beschreibungdescription
Die Erfindung betrifft eine Wicklung für einen Transformator, insbesondere eine Hochspannungswicklung für einen Transformator, sowie ein Verfahren zur Herstellung der Wicklung.The invention relates to a winding for a transformer, in particular a high-voltage winding for a transformer, and to a method for producing the winding.
Eine Wicklung für einen Transformator oder eine Spule für einen solchen Transformator ist aus einem oder mehreren bandförmigen Leitern und einer Isoliermaterialschicht aus bandförmigem Isoliermaterial aufgebaut, die gemeinsam zu Windungen um einen Wicklungskern gewickelt sind. Die einzelnen Windungen der Wicklung weisen einen vorgegebenen Wicklungswinkel gegenüber der Wicklungsachse des Wicklungskerns auf und sind zueinander mit teilweiser Überlappung angeordnet, wobei zwischen zwei radial benachbarten Lagen von Windungen aus elektrisch leitendem Material eine Isolierschicht eingefügt ist.A winding for a transformer or a coil for such a transformer is composed of one or more band-shaped conductors and an insulating material layer of band-shaped insulating material, which are wound together in turns around a winding core. The individual turns of the winding have a predetermined winding angle with respect to the winding axis of the winding core and are arranged to each other with partial overlap, wherein between two radially adjacent layers of turns of electrically conductive material, an insulating layer is inserted.
Dabei kann eine Lage oder es können auch mehrere Lagen von Windungen aus elektrisch leitendem Material vorgesehen sein, welche Lagen, die radial übereinander liegen, einen mehrlagigen Transformator oder eine mehrlagige Spule bilden. Die Isolierschicht zwischen den Leitern verhindert Spannungsüberschläge zwischen den Lagen und ist demgemäß auf die größte vorkommende Spannungsdifferenz zwischen zwei Lagen ausgelegt.In this case, a layer or it can also be provided several layers of turns of electrically conductive material, which layers that lie radially above one another, form a multilayer transformer or a multi-layer coil. The insulating layer between the conductors prevents voltage flashovers between the layers and is thus designed for the largest occurring voltage difference between two layers.
Aus der DE 101 57 591 A1 ist eine Anordnung von Isoliermaterial beschrieben, bei der das Isoliermaterial gestuft gewickelt ist, so dass sich die Dicke des Isoliermaterials in axialer Richtung verändert. Abhängig von der Spannungsdifferenz zwischen jeweils den einzelnen Lagen der Windungen aus elektrisch leitendem Material ist die Isolierschicht an einem axialen Ende der Spule dicker als am anderen Ende, wobei die Isolierschicht zwischen den beiden folgenden Lagen aus elektrisch leitendem Material an der Stelle eine größere radiale Dicke aufweist, an der die erste Lage am dünnsten ist, wogegen das andere Ende der Lage sich in dem Bereich befindet, in dem die darunter befindliche Lage am dicksten ausgebildet ist. Dabei wird das Leitermaterial und die Isolation für die Wicklung gleichzeitig (simultan) aufgebracht beziehungsweise aufgewickelt. Die Rovingfasern für die Isolierungsschicht können in Umfangsrichtung und in einem Winkel zur Wickelachse (Radialverbände und Kreuzverbände) ausgebildet sein.From DE 101 57 591 A1 an arrangement of insulating material is described, in which the insulating material is wound in a stepped manner, so that the thickness of the insulating material changes in the axial direction. Depending on the voltage difference between each of the individual layers of the turns of electrically conductive material, the insulating layer at one axial end of the coil is thicker than at the other end, wherein the insulating layer between the two following layers of electrically conductive material at the point has a greater radial thickness at which the The first layer is thinnest, while the other end of the layer is in the region where the underlying layer is thickest. The conductor material and the insulation for the winding is simultaneously applied (simultaneously) or wound up. The roving fibers for the insulating layer may be formed circumferentially and at an angle to the winding axis (radial bandages and cross dressings).
Bei gleichzeitiger Wicklung von Leitermaterial und Isolation, speziell dann, wenn eine ansteigende Lagenisolation aufgebracht werden soll, ist es schwierig, eine Verstärkung in axialer Richtung einzubringen, weil alle Fasern in Umfangsrichtung verlaufen.With simultaneous winding of conductor material and insulation, especially when an increasing layer insulation is to be applied, it is difficult to introduce a reinforcement in the axial direction, because all fibers extend in the circumferential direction.
Aufgabe der Erfindung ist es, eine Lagenisolation aufzubringen, bei der auch eine Kraftaufnahme in axialer Richtung vorgesehen ist.The object of the invention is to provide a layer insulation, in which a force is also provided in the axial direction.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruches 1. Dabei wird die Herstellung einer gestuften Lagenisolation, wie sie aus der DE 101 57 591 A1 bekannt geworden sind, dadurch erzeugt, dass die Rovings nicht nur in Umfangsrichtung aufgewickelt, sondern auch in einem Winkel schräg zur Wickelachse aufgebracht sind. Dabei wird der Support für die Zuführung der Lagenisolation hin- und hergefahren, das heißt in axialer Richtung vorgeschoben und zurückgefahren, wobei dies so gestaltet sein kann, dass sich gleichzeitig eine gestufte oder gerade ansteigende Isolation ergibt. Dabei wird bei Erhöhung der Anzahl der Stufen sich die Isolation immer mehr einer eher geraden ansteigenden Isolation annähern.This object is achieved by the features of claim 1. In this case, the production of a layered layer insulation, as they have become known from DE 101 57 591 A1, generated by the fact that the rovings wound not only in the circumferential direction, but also at an angle are applied obliquely to the winding axis. In this case, the support for the supply of the layer insulation is moved back and forth, that is advanced and retracted in the axial direction, and this can be designed so that at the same time results in a stepped or just rising insulation. As the number of stages increases, the isolation will more and more approximate to a more evenly rising isolation.
Das Isolationsmaterial kann entweder ein Glas- oder auch ein Polyesterroving sein, der mit Gießharz getränkt ist. Das Isoliermaterial kann aber auch mit einem Harz im sogenannten B-Zustand, in dem das Harz noch flüssig ist, möglicherweise mit expandierendem Füllstoff, getränkt werden. Als Isolationsmaterialien könnten auch Vliese oder Gewebebänder verwendet werden. Der Begriff „Faserrovings" umfasst daher alle möglichen geeigneten und ähnlich wirkenden Materialien.The insulating material may be either a glass or a polyester roving, which is impregnated with casting resin. However, the insulating material may also be impregnated with a resin in the so-called B-state in which the resin is still liquid, possibly with expanding filler. As insulation materials could also Nonwovens or fabric tapes are used. The term "fiber rovings" therefore includes all possible suitable and similar acting materials.
Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments and improvements of the invention can be found in the dependent claims.
Erfindungsgemäß also sind die Lagen aus Isoliermaterial in einem Winkel zur Wickelachse aufgebracht.According to the invention, the layers of insulating material are applied at an angle to the winding axis.
Zur Herstellung der Lagen aus Isoliermaterial werden Faserrovings aufgebracht, welche bezogen auf die Wickelachse schräg aufgebracht sind.To produce the layers of insulating fiber rovings are applied, which are applied obliquely relative to the winding axis.
Dabei sind die Lagen aus Isoliermaterial, die durch Faserrovings gebildet sind, zumindest in den Stufungsbereichen, die eine größere radiale Lagendicke aufweisen, d. h. insbesondere diejenigen an dem jeweiligen Ende der Spule, kreuzweise aufgebracht.In this case, the layers of insulating material which are formed by fiber rovings, at least in the staging areas which have a greater radial layer thickness, d. H. especially those at the respective end of the coil, applied crosswise.
Die Lagen aus Isoliermaterial können dabei dadurch aufgebracht werden, dass die Spule an der Zuführungsstelle vorbeigefahren wird; es besteht natürlich auch die Möglichkeit, dass die Zuführungsstelle bezogen auf die feststehende Spule verschoben wird.The layers of insulating material can thereby be applied, that the coil is moved past the feed point; Of course, there is also the possibility that the feed point is moved relative to the fixed coil.
Zur Herstellung einer kreuzweisen Lage kann dann die Faserrovingszuführung hin- und her in Richtung der Wickelachse verfahren werden.To produce a crosswise position, the fiber roving feed can then be moved back and forth in the direction of the winding axis.
Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.Reference to the drawing, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements of the invention and other advantages will be explained and described in detail.

Fig. 2 die Ausrichtung eines Isoliermaterialbandes gemäß der Erfindung und Fig. 3 eine schematische Darstellung einer Standardausrüstung eines Bandstranges aus Isoliermaterial.Fig. 2 shows the orientation of a Isoliermaterialbandes according to the invention and Fig. 3 is a schematic representation of a standard equipment of a strip of tape made of insulating material.
Auf einen Kern 10 einer Spule 11 ist eine erste radial innere Lage 12 aus Leitermaterial aufgewickelt, welche Lage aus mehreren Lagenabschnitten 13, 14, 15 ... zusammengesetzt ist, wobei die einzelnen Lageabschnitte 13, 14, 15 sich überdecken. Als Leitermaterial ist hier ein Leiterbandmaterial dargestellt. Natürlich könnten auch Leiter mit runden oder rechteckigem Querschnitt verwendet werden. Insoweit ist die Erfindung nicht auf Leiterbandmaterial beschränkt. Auf der radial inneren Lage des elektrischen Leitermaterials ist eine Lage 16 aus isolierendem Material aufgewickelt, welche Lage 16 mit Stufen gewickelt ist, wobei am rechten Ende (in der Zeichnung) die Dicke Di entsprechend den Erfordernissen der Spannungstragfähigkeit gering ist, wogegen am in der Zeichnung links befindlichen Ende die Dicke D2 der Isolierlage größer ist. Dazwischen befinden sich mehrere Stufen 17, 18 und 19, abhängig von der axialen Länge der Wicklung, die insgesamt die Bezugsziffer 20 erhalten hat.On a core 10 of a coil 11, a first radially inner layer 12 of conductor material is wound, which layer of several layer sections 13, 14, 15 ... is composed, wherein the individual bearing portions 13, 14, 15 overlap. As a conductor material here a conductor strip material is shown. Of course, conductors with a round or rectangular cross-section could also be used. In that regard, the invention is not limited to conductor strip material. On the radially inner layer of the electrical conductor material, a layer 16 of insulating material is wound, which layer 16 is wound with steps, wherein at the right end (in the drawing), the thickness Di corresponding to the requirements of the Spannungsstragfähigkeit is low, while am in the drawing left end located the thickness D 2 of the insulating layer is greater. In between there are several stages 17, 18 and 19, depending on the axial length of the winding, which has been given the reference numeral 20 in total.
Auf der Lage 16 aus isolierendem Material befindet sich eine radial außen liegende zweite Lage 21 aus elektrisch leitendem Material, die in gleicher weise ausgebildet ist wie die Lage 16; die hierauf aufgebrachte äußere Lage 22 aus isolierendem Material ist in ähnlicher Weise aufgebaut wie die Lage 16, wobei allerdings die radiale Dicke D3 in dem Bereich liegt, in dem die Lage 16 mit der größten Dicke D2 liegt; am anderen, hier rechts befindlichen Ende besitzt die Lage des Isoliermaterials die radiale Dicke D4, wobei auch hier Stufen 23, 24, 25 vorgesehen sind.On the layer 16 of insulating material is a radially outer second layer 21 of electrically conductive material, which is formed in the same way as the layer 16; the applied thereto outer layer 22 of insulating material is constructed in a similar manner as the layer 16, wherein, however, the radial thickness D 3 is in the range in which the layer 16 is located with the largest thickness D 2 ; At the other end, located on the right-hand side, the position of the insulating material has the radial thickness D 4 , steps 23, 24, 25 being provided here as well.
Wie in der DE 101 57 591 A1 dargestellt, ist die radiale Dicke der Isolierlagen 16 und 22 entsprechend der Spannungsdifferenz zwischen zwei Lagen aus leitendem Material ausgelegt.As shown in DE 101 57 591 A1, the radial thickness of the insulating layers 16 and 22 is designed according to the voltage difference between two layers of conductive material.
Zur Herstellung der Lagen 16 und 22 ist gemäß Fig. 3 Rovingband 30 aus isolierendem Material so aufgewickelt, dass der Rovingstrang 30 exakt in Umfangsrichtung verläuft, was eine standardmäßige Ausführung darstellt und insoweit Stand der Technik ist. Zur erfind u ngsgemäßen Herstellung der Lagen gemäß Fig. 1 wird gemäß Fig. 2 auf einen Spulenkörper 31 oder eine Spule 31 ein Band 32 aus elektrisch isolierendem Material, hier ein Rovingband aufgebracht, welches unter einem Winkel α zu einer Ebene E verläuft, die senkrecht zur Längsachse M-M der Spule 31 verläuft. Dabei kann das Rovingband 32 hin- und herbewegt werden, sodass wie strichliert mit 32a dargestellt, der Winkel α beidseitig zu einer Ebene verläuft, die senkrecht zur Mittelachse M-M ausgerichtet ist. Mit anderen Worten: Durch Hin- und Herfahren eines nicht näher dargestellten Supports in Doppelpfeilrichtung P kann das Rovingband in einer Zickzack-Ausrichtung auf die Spule 31 aufgewickelt werden. Es besteht natürlich auch die Möglichkeit, dass, je nach Ausbildung des Winkels α, die Zuordnung des Bandes 32 zur Spule 31 immer in der gleichen Richtung verläuft, wie in der Zeichnung Fig. 2 dargestellt.For the production of the layers 16 and 22, as shown in FIG. 3, roving strip 30 of insulating material is wound in such a way that the roving strand 30 runs exactly in the circumferential direction, which represents a standard embodiment and is state of the art to that extent. 2, a strip 32 of electrically insulating material, here a roving strip, which extends at an angle α to a plane E perpendicular to FIG. 2, is applied to a bobbin 31 or a coil 31 to the longitudinal axis MM of the coil 31 extends. In this case, the roving 32 can be moved back and forth, so that as shown in phantom with 32a, the angle α extends on both sides to a plane which is aligned perpendicular to the central axis MM. In other words, by reciprocating a support not shown in the double arrow direction P, the roving band can be wound in a zigzag orientation on the coil 31. Of course, there is also the possibility that, depending on the design of the angle α, the assignment of the belt 32 to the coil 31 always runs in the same direction, as shown in the drawing Fig. 2.
Mit der Ausgestaltung mit dem Hin- und Herfahren des Rovingbandes 32 können in gleicher Weise die Stufen 17, 18, 19 beziehungsweise 22, 23, 24 erzeugt werden, wobei der Winkel α nur klein genug ausgebildet sein muss.With the configuration with the reciprocating of the roving 32, the steps 17, 18, 19 and 22, 23, 24 can be generated in the same way, wherein the angle α must be formed only small enough.
Das Hin- und Herfahren des Supports gemäß Pfeilrichtung P kann natürlich auch so gestaltet werden, dass außer einer gestuften Isolation eine gerade, keilförmig ausgebildete Isolation hergestellt werden kann. Hierbei sind die Verweilzeiten des Isolationssupports an Stellen mit dicker Lageisolation größer zu wählen, was natürlich auch bei der gestuften Isolationslagen der Fall ist. Dabei wäre bei einer größeren Anzahl der Stufen eine Annäherung an die gerade keilförmige Isolation möglich.The back and forth of the support according to the direction of arrow P can of course be designed so that in addition to a stepped insulation, a straight, wedge-shaped insulation can be made. Here, the residence times of the insulation support at locations with thick layer insulation to choose greater, which of course is also the case with the graded insulation layers. In this case, an approach to the straight wedge-shaped insulation would be possible with a larger number of stages.
Dass natürlich der Support außer der Bewegung P in Doppelpfeilrichtung auch eine zusätzliche Längsbewegung in Pfeilrichtung L beziehungsweise in entgegengesetzter Richtung L1 ausführen muss, um die gesamte Länge der Spule 31 zu überdecken, ist selbstverständlich. That of course the support except the movement P in the double arrow direction must also perform an additional longitudinal movement in the direction of arrow L or in the opposite direction L1 to cover the entire length of the coil 31 is understood.
