Abstract

The winding, consisting of double pancake coils, has its impedance altered by varying the number of cross-overs in the leads connecting parallel pancake coils. With all the interconnecting wires parallel and no cross-overs, the impedance of the winding, is at its highest due to the phasing of the currents in parallel wires, whilst with all interconnecting wires crossed the impedance is at its lowest. Intermediate numbers of cross-overs give intermediate impedances. Crossing or uncrossing wires thus allows the winding properties to be simply altered manufacture.

Wicklung aus Doppelscheibenspulen für den Wirkwiderstand von FiIterkreisdrossein Winding from double disc coils for the effective resistance of filter circuit inductors

Die Erfindung betrifft eine Wicklung aua Doppelscheibenspulen für den Wirkwiderstand von Filterkreisdrosseln mit zwei oder mehreren radial parallel übereinander gewickelten und außerhalb der Wicklung «cusgekreuzten Drähten.The invention relates to a winding of double-disk coils for the effective resistance of filter circuit reactors two or more wires wound radially parallel one above the other and crossed outside the winding.

Für den Betrieb von Gleichstromübertragungsanlagen, insbesondere von Hochspannungsgleichstromübertragungsanlagen, «erden sogenannte Filterkreisdrosseln mit genau bestimmtem Wirkwiderstand benötigt. Die exakte Einhaltung des Wirkwiderstandes dieser Drosseln ist aus Resonanzgründen sehr wichtig.For the operation of direct current transmission systems, especially high-voltage direct current transmission systems, «So-called filter circuit reactors with a precisely determined effective resistance are required. The exact compliance with the effective resistance this choke is very important for reasons of resonance.

In der Praxis ist es nicht mit hinreichender Genauigkeit möglich, den Wirkwiderstand einer solchen Filterkreisdrosselspule im voraus mit ausreichender Genauigkeit zu berechnen und festzulegen. Der bei der Auslegung und Fertigung von FiIterkreisdrossein in Wirklichkeit erreichte Wirkividerstand kann erst nach Fertigstellung durch Messung im Prüffeld ermittelt werden.In practice, it is not possible with sufficient accuracy to determine the effective resistance of such a filter circuit inductor to be calculated and specified in advance with sufficient accuracy. The in the interpretation and Production of filter circuit throttles achieved in reality The effective dividend can only be determined after completion by measuring in the test field.

Der Erfindung liegt die Aufgabe zugrundef anzugeben wie der Wirkwiderstand einer Filterkreisdrossel nachträglich, d. h. nach Fertigstellung in einfacher Weise verändert und einem gewünschten Wert in engen Grenzen angepaßt werden kann. Bei einer Wicklung aus Doppelscheibenspulen von Filterkreisdrosseln mit zwei oder mehreren radial parallel übereinander gewickelten und außerhalb der Wicklung ausgekreuzten Drähten, wird die Aufgabe erfindungsgemäß dadurch gelöst, daß der Wirkwiderstand der Wicklung durch Verändern des Verhältnisses der ausgekreuzten zu den nicht ausgekreuzten Spulen eingestellt ist.The invention is based on the object f indicate how the effective resistance of a filter reactor subsequently, ie after completion changed in a simple manner and a desired value can be adjusted within narrow limits. In the case of a winding of double disc coils of filter circuit chokes with two or more wires wound radially parallel one above the other and crossed outside the winding, the object is achieved according to the invention in that the effective resistance of the winding is set by changing the ratio of the crossed to the non-crossed coils.

Bei der Verwendung von parallelen Drähten für Wicklungen elektrischer Maschinen ist man immer bestrebt, durch zyklische Vertauschung der Drähte jedem Draht gleiche Länge und gleiche Lage im magnetischen Feld zu geben, um durch ungleiche Ströme verursachte ZusatzVerluste in den parallelen Drähten weitgehend zu vermeiden. Bei der vorliegenden Erfindung wird von dieser Erscheinung in umge kehrt em Sinne Gebrauch gemacht, in dem ein größerer oder kleinerer Teil der Doppelspulen ausgekreuzt bzw. nicht ausgekreuzt wird. Bei Vergrößerung der Anzahl der Auskreuzungen wird der Wirkwiderstand erniedrigt, bei der Aufhebung von Auskreuzung wird der Wirkwider stand der Drossel erhöht.When using parallel wires for windings In electrical machines, one always strives to make every wire the same by cyclically interchanging the wires Length and the same position in the magnetic field in order to avoid additional losses caused by unequal currents in the Avoid parallel wires as much as possible. In the present invention, this phenomenon is reversed Made use of in the sense that a larger or smaller part of the double coils are crossed out or not is crossed out. If the number of crossings is increased, the effective resistance is reduced Resolving outcrossing becomes the effective resistance Throttle increased.

In den in der Anlage befindlichen Zeichnungen ist in den Figuren 1 bis 3 am Beispiel einer aus Doppelspulen bestehenden Wicklung aus zwei parallelen Drähten die Variationsmöglichkeit dargelegt.In the drawings in the system, FIGS. 1 to 3 use the example of a double coil existing winding of two parallel wires, the possible variations are shown.

Figur 1 zeigt eine Wicklung aus Scheibenspulen, wobei an allen äußeren Spulenübergängen die parallelen Leiter ausgekreuzt sind. Hierbei ist der Wirkwiderstand der Wicklung am kleinsten. In Figur 2 sind die Auskreuzungen an den oberen beiden Doppelspulen bei 3 aufgehoben, so daß gegenüber Figur 1 eine Erhöhung des Wirkwiderstandes eintritt.FIG. 1 shows a winding made of disc coils, with the parallel conductors at all outer coil transitions are crossed out. Here the effective resistance is the Winding smallest. In Figure 2, the crossings on the upper two double coils at 3 are canceled, so that compared to Figure 1 there is an increase in the effective resistance.

Auf die erfindungsgemäße Weise kann der Wirkwiderstand soweit erhöht werden, bis, wie in Figur 3 gezeigt, bei allen Spulen die Auskreuzungen der parallelen Drähte aufgehoben sind. In diesem Fall ist der Wirkwiderstand der Wicklung infolge des phasenverschobenen Verlaufs der Teilströme in den beiden parallelen Drähten durch die Wicklung und der dadurch bedingten ZusatzVerluste am größten.In the manner according to the invention, the effective resistance can be increased until, as shown in FIG. 3, at The crossings of the parallel wires are eliminated in all coils. In this case the effective resistance is the Winding due to the phase-shifted course of the partial currents in the two parallel wires through the Winding and the resulting additional losses.

Die zum möglichen Auskreuzen vorgesehenen Spulenverbindungen sind am äußeren Umfang der Wicklung angeordnet. Sie sind dadurch leicht zugänglich. Das Umschalten der parallelen Drähte vom ausgekreuzten in den nicht ausgekreuzten Zustand erfordert in diesem Fall den geringsten Werkstattaufwand .The coil connections provided for possible crossover are arranged on the outer circumference of the winding. she are therefore easily accessible. Switching the parallel wires from crossed out to not crossed out In this case, the condition requires the least amount of workshop effort.

Mit der vorliegenden Erfindung ist eine einfache Möglichkeit gegeben, eine feinstufige Einstellung des Wirkwiderstandes von Drosselwicklungen aus parallelen Drähten nachträglich und ohne zusätzliche Mittel vorzunehmen.The present invention provides a simple way of fine-tuning the effective resistance of inductor windings made of parallel wires can be carried out retrospectively and without additional funds.
