Abstract

The fine control winding is designed as a layer winding with at least two parallel branches and subwinders per control stage. At least two parallel conductors are assigned to each branch. The layer winding consists of two or more layers wound on top of one another radially. The subconductors from which the subwindings of each control stage are built are looped such that the last turn, or a part of the last turn, of a subconductor in one layer is connected to the first turn of a part of the first turn of this subconductor in the next layer.

Description

Die Erfindung betrifft eine Feinregelwicklung für einen Hochstromtransformator oder eine Hochstromdrosselspule, ausgeführt als Lagenwicklung mit mindestens zwei, gegenüber der Mitte der Wicklung symmetrisch angeordneten, Parallelzweigen und Teilwicklungen je Regelstufe, die einzeln achsial geschleift sind.The invention relates to a fine control winding for a high-current transformer or a high-current choke coil, designed as a layer winding with at least two parallel branches and partial windings per control stage, which are arranged symmetrically with respect to the center of the winding and which are individually looped axially.

Eine derartige Feinregelwicklung ist aus der deutschen Offenlegungsschrift 28.41592 bekannt.Such a fine control winding is known from German published application 28.41592.

Bei Hochströmen entstehen in einfachen massiven Leitern erhebliche Extraverluste. Man hat versucht, diese Verluste dadurch zu begrenzen, dass diese einfachen Leiter in eine Anzahl Parallelleiter aufgeteilt werden. Die Ausführung derartiger Feinregelwicklungen mit Parallelleitern in einer Einlagenwicklung führt jedoch vielfach zu einer hohen Wicklung. Um die Höhe der Wicklung begrenzt zu halten, können niedrige, jedoch breite Leiter angewandt werden. Eine derartige Wicklung hat aber vielfach eine schlechtere Kühlung und einen höheren Extraverlust. Es ist die Aufgabe der Erfindung, für diese Nachteile eine Lösung zu bieten.In the case of high currents, substantial extra losses occur in simple solid conductors. Attempts have been made to limit these losses by dividing these simple conductors into a number of parallel conductors. However, the execution of such fine control windings with parallel conductors in a single-layer winding often leads to a high winding. In order to keep the height of the winding limited, low but wide conductors can be used. However, such a winding often has poorer cooling and a higher extra loss. It is the object of the invention to offer a solution to these disadvantages.

Dies wird erfindungsgemäss dadurch erzielt, dass je Regelstufe mindestens zwei Parallelleiter angeordnet sind, die Lagenwicklung aus zwei oder mehr radial aufeinandergewickelten Lagen besteht und die Teilwicklungen je Regelstufe aus Teilleitern bestehen, die untereinander achsial derart geschleift sind, dass die letzte Windung oder ein Teil der letzten Windung eines Teilleiters in der einen Lage mit der ersten Windung oder einem Teil der ersten Windung dieses Teilleiters in einer nächstfolgenden Lage verbunden ist.This is achieved according to the invention in that at least two parallel conductors are arranged for each control stage, the layer winding consists of two or more layers wound radially on one another and the partial windings per control stage consist of partial conductors which are axially looped with one another such that the last turn or part of the last The winding of a partial conductor in one layer is connected to the first winding or a part of the first winding of this partial conductor in a next layer.

Indem auf diese Weise geschleift wird, wird erzielt, dass die gesonderten Windungen und falls vorhanden, Teile der gesonderten Windungen der Teilleiter je Regelstufe der Feinregelwicklungen mindestens einmal an der gleichen Stelle im Hauptstreufeld vorkommen, wodurch das Entstehen von Ausgleichströmen in den Teilleitern vermieden wird.By grinding in this way, it is achieved that the separate windings and, if present, parts of the separate windings of the partial conductors for each control stage of the fine control windings occur at least once at the same point in the main stray field, thereby avoiding the occurrence of compensating currents in the partial conductors.

Die Kühlung von vorstehend genannten Regelwicklungen kann noch verbessert werden, indem zwischen zwei oder mehr Lagen ein Kühlspalt angeordnet wird.The cooling of the above-mentioned control windings can be further improved by arranging a cooling gap between two or more layers.

Die Erfindung ist im folgenden anhand von Zeichnungen näher beschrieben.The invention is described below with reference to drawings.

Figur 1 zeigt eine erfindungsgemässe Feinregelwicklung mit zwei Parallelzweigen, einer Zweilagenwicklung, zwei Parallelteilleitern je Regelstufe und einer ganzen Anzahl Windungen je Teilleiter je Wickellage.1 shows an inventive Fine control winding with two parallel branches, a two-layer winding, two P per arallelteilleitern control stage and a whole number of turns of each partial conductor per winding layer.

Figur 2 zeigt dieselbe Regelwicklung wie Figur 1, nun jedoch mit verbesserter Kühlung mittels eines Kühlspaltes zwischen den Wickellagen.Figure 2 shows the same control winding as Figure 1, but now with improved cooling by means of a cooling gap between the winding layers.

Figur 3 zeigt eine erfindungsgemässe Feinregelwicklung mit zwei Parallelzweigen, einer Dreilagenwicklung, drie Parallelteilleitern je Regelstufe und einer ganzen Anzahl Windungen je Teilleiter je Wickellage.FIG. 3 shows a fine control winding according to the invention with two parallel branches, a three-layer winding, three parallel partial conductors per control stage and a whole number of turns per partial conductor per winding layer.

Figur 4 zeigt eine erfindungsgemässe Feinregelwicklung mit zwei Parallelzweigen, einer Zweilagenwicklung, zwei Parallelleitern je Regelstufe, fünf Windungen je Teilleiter je Regelstufe, von denen zweieinhalb Windung je Teilleiter je Wickellage.FIG. 4 shows a fine control winding according to the invention with two parallel branches, a two-layer winding, two parallel conductors per control stage, five turns per partial conductor per control stage, of which two and a half turns per partial conductor per winding position.

Die Zahlen in den Figuren 1, 2 und 3 sind Stellennummern der Windungen in den Wicklungen. Die Zahlen in der Figur 4 sind Stellennummern, aber bezeichnen zugleich die Gesamtzahl Windungen je Teilleiter von der Mitte der Wicklung an.The numbers in Figures 1, 2 and 3 are position numbers of the turns in the windings. The numbers in FIG. 4 are position numbers, but also denote the total number of turns per partial conductor from the middle of the winding.

In den Figuren 1 und 2 sind die Teilwicklungen zwischen den Abzweigungen SO - S1, S1 - S2 usw. und zwischen den Abzweigungen SO' - S1', S1' - S2' usw., respektive je zu einem der zwei Zweige der Feinregelwicklung gehörig, aus zwei Parallelteilleitern aufgebaut. So ist z.B. die Teilwicklung zwischen den Abzweigungen SO und S1 aus einem Teilleiter mit den aussenliegenden Windungen 1a, 2a, 3a und den innenliegenden Windungen 4a, 5a, 6a aufgebaut, während der andere Parallelteilleiter aus den innenliegenden Windungen 1b, 2b, 3b und den aussenliegenden Windungen 4b, 5b, 6b aufgebaut ist.In FIGS. 1 and 2, the partial windings between the branches SO - S1, S1 - S2 etc. and between the branches SO '- S1', S1 '- S2' etc., respectively belong to one of the two branches of the fine control winding, made up of two parallel partial conductors. For example, the partial winding between the branches SO and S1 is made up of a partial conductor with the external turns 1a, 2a, 3a and the internal turns 4a, 5a, 6a, while the other parallel partial conductor consists of the internal turns 1b, 2b, 3b and the external turns 4b, 5b, 6b is constructed.

In der Figur 3 sind die Teilwicklungen zwischen den Abzweigungen SO - S1 usw. und SO' - S1' usw., respektive je zu einem der zwei Zweige der Feinregelwicklung gehörig, aus drie Parallelteilleitern aufgebaut, So ist z.B. die Teilwicklung zwischen den Abzweigungen SO und S1 aus einem Teilleiter mit den aussenliegenden Windungen 1, 2a, 3a, den Windungen 4a, 5a und 6a in der mittelsten Wickellage und den innenliegenden Windungen 7a, 8a und 9a aufgebaut; der zweite Teilleiter ist aus den Windungen 1b, 2b, 3b in der mittelsten Wickellage, den innenliegenden Windungen 4b, 5b, 6b und den aussenliegenden Windungen 7b, 8b aufgebaut; während der dritte Teilleiter aus den innenliegenden Windungen 1c, 2c, 3c, den aussenliegenden Windungen 4c, 5c, 6c und den Windungen 7c, 8c und 9c in der mittelsten Wickellage aufgebaut ist.In Figure 3, the partial windings are between The branches SO - S1 etc. and SO '- S1' etc., respectively belonging to one of the two branches of the fine control winding, are made up of three parallel partial conductors 1, 2a, 3a, the windings 4a, 5a and 6a in the middle winding position and the inner windings 7a, 8a and 9a; the second partial conductor is made up of turns 1b, 2b, 3b in the middle winding position, the inside turns 4b, 5b, 6b and the outside turns 7b, 8b; while the third partial conductor is made up of the inner turns 1c, 2c, 3c, the outer turns 4c, 5c, 6c and the turns 7c, 8c and 9c in the middle winding position.

In Figur 4 sind die Teilwicklungen zwischen den Abzweigungen SO - S1, S1 - S2 usw. und SO' - S1', S1' - S2' usw., respektive je zu einem der zwei Zweige der Feinregelwicklung gehörig, aus zwei Parallelteilleitern, mit fünf Windungen je Teilleiter je Regelstufe, von denen zweieinhalb Windung je Teilleiter je Wickellage aufgebaut. So ist z.B. die Teilwicklung zwischen den Abzweigungen SO und S1 aus dem Teilleiter beginnend beiOa und gewickelt Oa, 1/2 a, 1a, 1 1/2a, 2a, 2 1/2a in der aussenliegenden Wickellage anschliessend gewickelt 2 1/2a, 3a, 2 1/2a, 4a, 4 1/2a, 5a in der innenliegenden Wickellage und endend bei 5a, und aus dem Teilleiter beginnend bei Ob und gewickelt Ob, 1/2b, 1b, 1 1/2b, 2b, 2 1/2b in der innenliegenden Wickellage anschliessend gewickelt 2 1/2b, 3b, 3 1/2b, 4b, 4 1/2b, 5b in der aussenliegenden Wickellage und endend bei 5b aufgebaut.In Figure 4, the partial windings between the branches SO - S1, S1 - S2 etc. and SO '- S1', S1 '- S2' etc., respectively belonging to one of the two branches of the fine control winding, consisting of two parallel partial conductors with five Windings per partial conductor per control stage, of which two and a half turns per partial conductor per winding layer. For example, the partial winding between the branches SO and S1 from the partial conductor starting at Oa and wound Oa, 1/2 a, 1a, 1 1 / 2a, 2a, 2 1 / 2a in the outer winding position then wound 2 1 / 2a, 3a, 2 1 / 2a, 4a, 4 1 / 2a, 5a in the inner winding layer and ending at 5a, and from the partial conductor starting at Ob and wound Ob, 1 / 2b, 1b, 1 1 / 2b, 2b, 2 1 / 2b in the inner winding layer then wound 2 1 / 2b, 3b, 3 1 / 2b, 4b, 4 1 / 2b, 5b in the outer winding layer and ending at 5b.

Wenn die Anzahl Windungen je Teilleiter n und die Anzahl Wickellagen m ist, so beträgt die Anzahl Windungen je Teilleiter je Wickellage n/m, wobei n> m > 1 ist und n und m ganze Zahlen sind.If the number of turns per partial conductor is n and the number of winding layers is m, the number of turns per partial conductor per winding layer is n / m, where n> m> 1 and n and m are integers.

So ist für das in Figur 1 gegebene Beispiel: n = 5, m = 2 und beträgt die Anzahl Windungen je Teilleiter je Wickellage 2 1/2. S o is for the example given in FIG. 1: n = 5, m = 2 and the number of turns per partial conductor per winding layer is 2 1/2.

Der Anfang und das Ende der Teilwicklungen und somit auch der Teilleiter, aus denen jede Teilwicklung zusammengesetzt ist, liegen ungefähr in einer gemeinsamen Ebene durch die Achsenlinie der Regelwicklung.The beginning and the end of the partial windings and thus also the partial conductor, from which each partial winding is composed is approximately in a common plane through the axis line of the control winding.

Die Verbindung zwischen der letzten Windung oder einem Teil der letzten Windung eines Teilleiters in der einen Lage und der ersten Windung oder einem Teil der ersten Windung dieses Teilleiters in einer nächstfolgenden Lage liegt in einer Ebene durch die Achsenlinie der Regelwicklung, die gegenüber der Ebene durch den Anfang und das Ende des betrachteten Teilleiters, längs des Umfangs der Reqelwicklunq gesehen, einen Winkel von:

einschliesst, worin

  • n = Anzahl Windungen je Teilleiter
  • m = Anzahl Wicklungen
  • p = die Anzahl schon gewickelte Lagen wonach Durchverbinding erfolgt.
The connection between the last turn or part of the last turn of a partial conductor in one position and the first turn or part of the first turn of this partial conductor in a next position lies in a plane through the axis line of the control winding, which is opposite the plane through the The beginning and the end of the subconductor under consideration, seen along the circumference of the reqel winding, an angle of:
Figure imgb0001
 includes what
  • n = number of turns per partial conductor
  • m = number of windings
  • p = the number of layers already wound, after which through-connection takes place

Hieraus geht hervor, dass, wenn

Figure imgb0002
= eine ganze Zahl ist,It follows that if
Figure imgb0002
 = is an integer,

der Anfang und das Ende eines Teilleiters und die Durchverbindungen des betreffenden Teilleiters, längs des Umfangs der Feinregelwicklung gesehen, in Ebenen durch die Achsenlinie der Regelwicklung liegen, die keinen Winkel miteinander einschliessen.the beginning and end of a partial conductor and the interconnections of the relevant partial conductor, seen along the circumference of the fine control winding, lie in planes through the axis line of the control winding, which do not form an angle with one another.

Für das in Figur 4 gegebene Beispiel dagegen, worin n = 5, m= 2 und p = 1 ist, zeigt sich, dass die Durchverbindungen in einer Ebene liegen, die gegenüber der Ebene durch den Anfang und das Ende des betrachteten Teilleiters, längs des Umfangs der Regelwicklung gesehen, einen Winkel von:

Figure imgb0003
einschliesst. Mit andern Worten, die Durchverbindungen liegen an der anderen Seite der Regelwicklung als die Abzweigungen.In contrast, for the example given in FIG. 4, in which n = 5, m = 2 and p = 1, it turns out that the interconnections lie in a plane which is opposite the plane through the beginning and the end of the subconductor under consideration, along the Seen circumference of the control winding, an angle of:
Figure imgb0003
 includes. In other words, the through connections are on the other side of the control winding than the branches.
