Description

Die Erfindung betrifft einen Hauptleiter für eine kapazitiv gesteuerte Hochspannungswicklung nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Herstellung eines Hauptleiters für eine kapazitiv gesteuerte Hochspannungswicklung nach dem Oberbegriff des Anspruchs 7.The invention relates to a main conductor for a capacitive controlled High-voltage winding according to the preamble of claim 1 and a method for producing a main conductor for a capacitively controlled high voltage winding according to the preamble of claim 7.

Aus der DE 199 26 540 C1 ist eine Hochspannungswicklung bekannt, bei welcher die Spulenwicklungen aus sogenannten Drilleitern hergestellt sind. Durch die Verwendung von Drilleitern werden die durch das Streufeld verursachten Zusatzverluste verringert. Darüberhinaus kann der zur Verfügung stehende Wickelraum durch einen höheren Füllfaktor besser ausgenutzt werden.From DE 199 26 540 C1, a high-voltage winding is known in which the Coil windings are made of so-called Drilleitern. By use Drilleitern reduces the additional losses caused by the stray field. Moreover, the available changing room by a higher Fill factor can be better utilized.

Die Herstellung ineinander gewickelter Spulen erfordert in jedem Fall Lötverbindungen, die bei der Verwendung von Drilleiter nur unter größeren Schwierigkeiten oder überhaupt nicht realisierbar sind. Bei der Verwendung von Drilleitern ist daher zur Vermeidung von Lötverbindungen eine fortlaufend wickelbare Doppelspulenschaltung anzustreben, in der die kapazitive Steuerung durch einen besonderen Steuerleiter erreichbar ist, dessen Lötverbindungen einfach und wirtschaftlich herstellbar sind.The production of nested coils requires in each case solder joints, those using ladder only with greater difficulty or are not feasible at all. When using Drilleitern is therefore to Prevention of solder joints a continuously windable double coil circuit to strive for in the capacitive control by a special control conductor can be reached, the solder joints are simple and economical to produce.

Bei der DE 199 26 540 C1 ist der Steuerleiter räumlich innerhalb des Hauptleiters angeordnet und ist von dem Hauptleiter galvanisch getrennt. Der Steuerleiter ist zwischen zwei Stapeln von flach aufeinander liegenden, gemeinsam den Hauptleiter bildenden Einzelleitern angeordnet. Zur galvanischen Trennung des Steuerleiters von dem Hauptleiter weist der Steuerleiter entweder eine Isolierung auf oder der Raum zwischen Steuerleiter und Hauptleiter ist durch eine Auffüllung oder durch eine Zwischenlage aus Isolierwerkstoff ausgefüllt. In DE 199 26 540 C1, the control conductor is spatially within the main conductor arranged and is galvanically isolated from the main conductor. The controller is between two stacks of flat superimposed, sharing the main conductor forming individual leaders. For galvanic isolation of the control conductor of the main conductor, the control conductor either insulation or the room between control conductor and main conductor is by a padding or by a Intermediate layer made of insulating material filled.

Durch die Anordnung des Steuerleiters zwischen den beiden Teilleiterstapeln besteht die Gefahr, daß der Steuerleiter während der Weiterverarbeitung des Drilleiters z. B. bei der Herstellung einer Transformatorenwicklung verschoben wird und dadurch die Isolierung des Steuerleiters oder der Teilleiter des Drilleiters zerstört werden kann. Bei der Herstellung der Wicklung besteht darüberhinaus die Gefahr, daß die erforderliche geometrisch korrekte Anordnung der einzelnen Lagen einer Wicklung nicht mehr gewährleistet ist.By the arrangement of the control conductor between the two sub-conductor stacks is the risk that the control conductor during further processing of the Drilleiters z. B. at the production of a transformer winding is moved and thereby the Insulation of the control conductor or the sub-conductor of the twisting conductor can be destroyed. In the Making the winding is beyond the risk that the required geometrically correct arrangement of the individual layers of a winding no longer is guaranteed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Hauptleiter mit einem Steuerleiter bereitzustellen, bei welchem eine Beschädigung der Isolierung sowohl des Steuerleiters als auch des Drilleiters vermieden ist. Darüberhinaus soll das Verhalten des Hauptleiters beim Wickelprozeß der Transformatorwicklung verbessert werden.The present invention has for its object to provide a main conductor with a To provide control conductor, in which damage to the insulation of both the Control conductor and the Drilleiters is avoided. In addition, the behavior of the Main conductor can be improved during the winding process of the transformer winding.

Diese Aufgabe wird durch die im Kennzeichen der Ansprüche 1 und 7 gelöst.This object is achieved by that in the characterizing part of claims 1 and 7.

Durch die Verwendung von zwei Drilleitern und die Anordnung des Steuerleiters zwischen den Drilleitern ist gewährleistet, daß beim üblichen Röbelprozeß keinerlei Veränderungen vorgenommen werden müssen. Die Fixierung des Steuerleiters innerhalb des Hauptleiters zwischen den beiden Drilleitern stellt sicher, daß der Steuerleiter sich nicht mehr verschieben kann.Through the use of two twisted conductors and the arrangement of the control conductor between the Drilleitern ensures that the usual Röbelprozeß no Changes need to be made. The fixation of the controller inside the main conductor between the two twisted ladders ensures that the Controller can not move anymore.

Bei der Herstellung der Drilleiter 1 und 2 wechselt aus den nebeneinander liegenden Stapeln 3 und 4 jeweils der oberste und unterste Leiter 5 in den anderen Stapel 3 und 4 über, wobei die Leiter 5 vorzugsweise um jeweils eine halbe Schrittlänge versetzt werden. Dabei wird bei ungeradzahligen Drilleitern eine gleichbleibende Gesamthöhe erreicht. The figure shows a main conductor for a capacitive controlled high voltage winding which is composed of two Drilleitern 1 and 2. Each twisting ladder has a variety of in two juxtaposed stacks 3, 4 located rectangular Partial 5 on. In the preparation of the Drilleiter 1 and 2 changes from the adjacent stacks 3 and 4 each of the top and bottom ladder 5 in the other stack 3 and 4, wherein the conductors 5 preferably by a half Step length to be offset.

As a creped paper is for reasons of strength micro-creped and calendered insulating paper used.

Zwischen den Drilleitern 1 und 2 sind mehrere aus Flachkupfer hergestellte Steuerleiter 7 angeordnet, die jeder für sich eine Isolierhülle 7a aus Papier aufweisen.
