Abstract
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.
- 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.

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.
- 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.

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.
