Abstract

The method involves producing intermediate isolations (A, B) between disks (1, 2) during a winding process. The intermediate isolations are divided into intermediate isolation areas (A1, B1) having a triangular cross-section and intermediate isolation areas (A2, B2) having an inversed triangular cross-section. An isolation is placed in one of the areas (A2) at a right side of one of the disks and another isolation is placed in another area (B1) at a left side of the disk when a disk winding unwinds from right to left simultaneously during winding of the disk.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Scheibenwicklung. Eine bevorzugte Anwendung liegt bei Hochspannungswicklungen von Trockentransformatoren.The invention relates to a method for producing a disk winding. A preferred application is high-voltage windings of dry-type transformers.

Besonders im Bereich der Hochspannungsspulen von gemäß der Vakuumverguss-Technik hergestellten Spulen werden Scheibenwicklungen verwendet. Hierbei wird ein Leiterband (Abmessungen z. B. 20 mm breit, 0,2 mm dick) zusammen mit einem Windungsisolator (z. B. 30 mm breit, 0,1 mm dick) aufeinander zu einer "Scheibe" gewickelt, wobei der Wicklungsanfang nahe des Wicklungskerns liegt. Nach z. B. 100 Windungen wird die Scheibe beendet, das Leiterband wird um 90° umgefaltet und zu einer neuen Scheibe in Richtung zum Wicklungskern heruntergeführt. Dort wird es erneut um 90° umgefaltet und es wird eine weitere Scheibe gewickelt. Eine solche Scheibenwicklung kann aus vielen derartiger, nebeneinander angeordneter Scheiben bestehen. Nach Vollendung der Scheibenwicklung, respektive der letzten Scheibe dieser Wicklung erfolgt eine Kapselung in einem Vakuum-Verguss-Verfahren.Disc windings are used particularly in the field of high-voltage coils of coils produced according to the vacuum casting technique. Here, a conductor strip (dimensions, for example, 20 mm wide, 0.2 mm thick) together with a winding insulator (eg., 30 mm wide, 0.1 mm thick) wound on each other to a "disc", the beginning of the winding located near the winding core. After z. B. 100 turns the disc is terminated, the conductor band is folded over by 90 ° and led down to a new disc in the direction of the winding core. There it is folded over again by 90 ° and another disc is wound. Such a disk winding may consist of many such juxtaposed disks. After completion of the disc winding, respectively the last disc of this winding, encapsulation takes place in a vacuum potting method.

Der Erfindung liegt die Aufgabe zugrunde, ein optimiertes Verfahren zur Herstellung einer Scheibenwicklung anzugeben.The invention has for its object to provide an optimized method for producing a disc winding.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zur Herstellung einer Scheibenwicklung mit mindestens drei nebeneinander angeordneten Scheiben,

  • wobei innerhalb eines Wickelprozesses simultan mit der Wicklung eine Zwischenisolation zwischen jeweils zwei Scheiben gefertigt wird,
  • wobei ein Verbindungsleiter vom Ende der einen Scheibe zum Anfang der weiteren Scheibe in Form einer Diagonalen innerhalb der Zwischenisolation verläuft und die Zwischenisolation hierdurch in zwei Teilbereiche unterteilt, nämlich einen ersten Zwischenisolationsbereich mit dreieckförmigem Querschnitt, welcher unterhalb dieser Diagonalen ausgebildet ist und einen zweiten Zwischenisolationsbereich mit umgekehrt dreieckförmigem Querschnitt, welcher oberhalb dieser Diagonalen ausgebildet ist,
  • wobei bei einer von links nach rechts fortschreitenden Scheibenwicklung simultan mit der Wicklung der Scheibe eine Isolation im zweiten Zwischenisolationsbereich links der Scheibe und eine Isolation im ersten Zwischenisolationsbereich rechts der Scheibe aufgebracht werden,
  • und wobei bei einer von rechts nach links fortschreitenden Scheibenwicklung simultan mit der Wicklung der Scheibe eine Isolation im zweiten Zwischenisolationsbereich rechts der Scheibe und eine Isolation im ersten Zwischenisolationsbereich links der Scheibe aufgebracht werden.
This object is achieved according to the invention by a method for producing a disk winding with at least three disks arranged next to one another,
  • wherein, within a winding process, an intermediate insulation between two slices is produced simultaneously with the winding,
  • wherein a connecting conductor extends from the end of the one disc to the beginning of the other disc in the form of a diagonal within the intermediate insulation and the intermediate insulation thereby divided into two subregions, namely a first intermediate isolation region with triangular cross-section, which is formed below these diagonals and a second intermediate isolation region with the other way round triangular cross-section, which is formed above these diagonals,
  • wherein in a disk winding proceeding from left to right simultaneously with the winding of the disk, an insulation in the second intermediate insulation area to the left of the disk and an insulation in the first intermediate insulation area are applied to the right of the disk,
  • and wherein in a disk winding progressing from right to left simultaneously with the winding of the disk, an insulation in the second intermediate insulation area to the right of the disk and an insulation in the first intermediate insulation area to the left of the disk are applied.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass innerhalb eines Wickelprozesses der gewünschte Verlauf der Verbindung zweier Scheiben miteinander realisiert werden kann, ohne dass dabei schwierig mit Isolation, beispielsweise Harz-Roving zu bewickelnde Hohlräume entstehen. Hierdurch werden gute elektrische Eigenschaften einer Hochspannungsspule bzw. eines Transformators bei kompaktem, raumsparendem Aufbau sichergestellt.The advantages that can be achieved with the invention are, in particular, that the desired course of the connection of two panes can be realized with one another within a winding process, without causing cavities to be wound with insulation, for example resin roving. As a result, good electrical properties of a high voltage coil or a transformer are ensured in a compact, space-saving design.

The in the example shown from left to right progressing, a winding core 8 enclosing disc winding 9 has four discs, wherein between the individual discs of the disc winding 9 is provided in each case an intermediate isolation. For this purpose, reference is also made to the input-side, also valid for the invention explanations. In terms of intermediate insulation, this means in detail:
    • between a first disk 1 and a second disk 2 a first intermediate insulation A is arranged,
    • between the second disc 2 and a third disc 3, a second intermediate insulation B is arranged,
    • between the third disc 3 and a fourth disc 4, a third intermediate insulation C is arranged.

Nachstehend soll die Herstellung der Zwischenisolation näher betrachtet werden.Below, the preparation of the intermediate insulation will be considered in more detail.

In Fig. 1 ist hierzu ein seitlicher Schnitt durch einen Abschnitt einer von links nach rechts fortschreitenden Scheibenwicklung 9 während eines betrachteten Fertigungsschrittes dargestellt. Im konkret dargestellten, betrachteten Fertigungsschritt ist die erste Scheibe 1 bereits fertig gestellt, während die zweite Scheibe 2 gerade gewickelt wird. Zwischen den Scheiben 1, 2 ist die Zwischenisolation A angeordnet. Jede Scheibe besitzt (bzw. soll besitzen) eine vorgegebene Anzahl an aus einem Leiterband 5 bestehenden Windungen, wobei sich zwischen je zwei Windungen ein ebenfalls bandförmiger Windungsisolator 6 befindet. Das Leiterband 5 ist durchgehend vom Ende der ersten Scheibe 1 zum Anfang der zweiten Scheibe 2 in Form eines Verbindungsleiters 7A geführt. Dieser Verbindungsleiter 7A entspricht innerhalb des Zwischenisolations-Querschnittes quasi einer Diagonalen der Zwischenisolation A, welche die Zwischenisolation A in zwei Teilbereiche unterteilt, nämlich

  • in einen ersten Zwischenisolationsbereich A1 mit dreieckförmigem Querschnitt, welcher unterhalb dieser Diagonalen ausgebildet ist und in welchem bereits im vorhergehenden Fertigungsschritt bei Wicklung der ersten Scheibe 1 eine Isolation aufgebracht worden ist sowie
  • in einen zweiten Zwischenisolationsbereich A2 mit umgekehrt dreieckförmigem Querschnitt, welcher oberhalb dieser Diagonalen ausgebildet ist und in welchem während des betrachteten Fertigungsschrittes simultan mit Wicklung der Scheibe 2 eine Isolation aufgebracht wird, was durch den mäanderförmigen Linienzug skizziert ist.
In Fig. 1 For this purpose, a lateral section through a portion of a progressing from left to right disc winding 9 is shown during a manufacturing step considered. In concrete, considered manufacturing step, the first disc 1 is already completed, while the second disc 2 is being wound. Between the discs 1, 2, the intermediate insulation A is arranged. Each disc has (or should own) a predetermined number of existing from a conductor strip 5 turns, which is also between each two turns band-shaped winding insulator 6 is located. The conductor strip 5 is guided continuously from the end of the first disc 1 to the beginning of the second disc 2 in the form of a connecting conductor 7A. This connecting conductor 7A corresponds within the Zwischenisolations-cross section quasi a diagonal of the intermediate insulation A, which divides the intermediate insulation A into two subregions, namely
  • in a first intermediate insulation region A1 with triangular cross section, which is formed below these diagonals and in which already in the previous manufacturing step in winding the first disc 1 has been applied insulation and
  • in a second intermediate isolation region A2 with an inverted triangular cross-section, which is formed above these diagonals and in which during the manufacturing step under consideration, an insulation is applied simultaneously with winding of the disc 2, which is outlined by the meandering polyline.

Hinsichtlich der Zwischenisolation B zwischen der während des betrachteten Fertigungsschrittes gewickelten Scheibe 2 und der im darauffolgenden Fertigungsschritt zu wickelnden Scheibe 3 gelten ähnliche Fertigungsmaßnahmen, denn diese Zwischenisolation B wird bezüglich ihres Querschnittes durch den quasi einer Diagonalen der Zwischenisolation B entsprechenden Verbindungsleiter 7B in gleicher Art und Weise in zwei Teilbereiche unterteilt, nämlich

  • in einen ersten Zwischenisolationsbereich B1 mit dreieckförmigem Querschnitt, welcher unterhalb dieser Diagonalen ausgebildet ist und in welchem während des betrachteten Fertigungsschrittes simultan mit der Wicklung der Scheibe 2 eine Isolation aufgebracht wird, was durch den mäanderförmigen Linienzug skizziert ist sowie
  • in einen zweiten Zwischenisolationsbereich B2 mit umgekehrt dreieckförmigem Querschnitt, welcher oberhalb dieser Diagonalen ausgebildet ist und in welchem erst im darauffolgenden Fertigungsschritt bei Wicklung der nächsten Scheibe 3 eine Isolation aufzubringen ist.
With regard to the intermediate insulation B between the wound during the production step slice 2 and the subsequent manufacturing step to be wound disc 3 similar manufacturing measures apply, because this intermediate insulation B is in cross section through the quasi diagonal of the intermediate insulation B corresponding connection conductor 7B in the same manner divided into two parts, namely
  • in a first intermediate isolation region B1 with triangular cross-section, which is formed below these diagonals and in which during the manufacturing step considered, an insulation is applied simultaneously with the winding of the disc 2, which is outlined by the meandering polyline and
  • in a second intermediate insulating region B2 with an inverted triangular cross-section, which is formed above these diagonals and in which only in the subsequent manufacturing step in winding the next disc 3 is to apply insulation.

Zusammenfassend betrachtet sieht die Erfindung demnach vor, eine Wicklung einer Scheibe zusammen mit zwei Teilbereichen der zu beiden Seiten des Scheibe benötigten Zwischenisolation herzustellen, wozu während der Wicklung des Leiterbandes 5 und des Windungsisolators 6 simultan Isolationen neben der Scheibe mit umgekehrt dreieckförmigem Querschnitt auf der einen (z. B. linken) Seite und dreieckförmigem Querschnitt auf der anderen (z. B. rechten) Seite aufgebracht werden.In summary, the invention accordingly provides to produce a winding of a disc together with two portions of the required for both sides of the disc intermediate insulation, including during the winding of the conductor strip 5 and the winding insulator 6, simultaneous insulations adjacent to the disk of inverse triangular cross-section are applied on one (eg, left) side and triangular cross-section on the other (eg, right) side.

Diese Isolationen können beispielsweise aus einem oder mehreren Glas-Rovings bestehen, die mit einem Harz getränkt sind. Alternativ hierzu kann auch ein vorimprägniertes Material verwendet werden. Speziell beim Nasswickelverfahren kann auch dafür gesorgt werden, dass die Zwischenräume zwischen dem Leiterband 5 und dem Windungsisolator 6 mit einem Harz gefüllt werden.For example, these insulations may consist of one or more glass rovings impregnated with a resin. Alternatively, a preimpregnated material may also be used. Especially in the case of the wet winding process, it is also possible to ensure that the spaces between the conductor strip 5 and the winding insulator 6 are filled with a resin.

In Fig. 2 is a side section through a portion of a finished disc winding 9 (from left to right progressing disc winding) shown, consisting of
  • the first disk 1, constructed from the conductor strip 5 in the desired number of turns and the winding insulator 6,
  • the second disc 2, constructed of the conductor strip 5 in the desired number of turns and the winding insulator 6,
  • the first intermediate insulation A between the disks 1 and 2 divided into the first intermediate insulating region A1 of triangular cross-section and the second intermediate insulating region A2 of inverse triangular cross-section, the connecting conductor 7A forming the diagonal interface between the two intermediate insulating regions A1, A2,

  • the second intermediate insulation B between the disks 2 and 3 divided into the first intermediate insulating region B1 of triangular cross-section and the second intermediate insulating region B2 of inverse triangular cross-section, the connecting conductor 7B forming the diagonal interface between the two intermediate insulating regions B1, B2,

Selbstverständlich gelten die vorstehenden Erläuterungen in ihrem gesamten Umfang lediglich zur Erläuterung der zwischen zwei Scheiben befindlichen Zwischenisolation, vorstehend der Zwischenisolationen A, B, C. Abweichend hiervon entfällt bei der ersten Scheibe 1 die Fertigung eines Zwischenisolationsbereichs mit umgekehrt dreieckförmigem Querschnitt (z. B. links der Scheibenwicklung bei einer von links nach rechts fortschreitenden Scheibenwicklung). Ebenfalls entfällt bei der letzten Scheibe, hier Scheibe 4 die Fertigung eines Zwischenisolationsbereichs mit dreieckförmigem Querschnitt (z. B. rechts der Scheibenwicklung bei einer von links nach rechts fortschreitenden Scheibenwicklung).Of course, the preceding explanations apply in their entire scope merely to explain the intermediate insulation located between two panes, above the intermediate insulations A, B, C. Deviating from this, the production of an intermediate insulating region with an inverted triangular cross-section (eg on the left the disk winding in a disk winding progressing from left to right). Likewise, in the case of the last pane, in this case pane 4, the production of an intermediate insulation area with a triangular cross-section (eg on the right of the disk winding in the case of a disk winding proceeding from left to right) is omitted.

Selbstverständlich gelten die vorstehenden Erläuterungen in ihrem gesamten Umfang auch bei einer von rechts nach links fortschreitenden Scheibenwicklung, wie dies in Fig. 4 skizziert ist.Of course, the above explanations apply in their entire scope even with a right-to-left advancing disc winding, as in Fig. 4 outlined.
