Description

Kontinuierlicher Drillleiter  Continuous drill ladder
Die gegenständliche Erfindung betrifft einen kontinuierlichen Drillleiter bestehend aus einer Mehrzahl einzelner, elektrisch isolierter Teilleiter, sowie ein Verfahren zur Herstellung eines solchen Drillleiters. Bekannterweise treten bei Transformatoren vor allem an den äußeren Spulen der Wicklung elektromagnetische Felder (Querfelder) auf, welche in den Wicklungsleitern Wirbelströme induzieren, die zu Wirbelstromverlusten führen. Wirbelstromverluste reduzieren den Wirkungsgrad des Transformators, führen aber auch zu lokal unerwünscht hohen Temperaturen, die wiederum zu einer Beschädigung der Wicklungsisolation führen kann. Durch die Verwendung von bekannten kontinuierlichen Drillleitern können solche Wirbelstromverluste reduziert werden. Drillleiter bestehen dabei aus einem Bündel von einzelnen, isolierten Einzelleitern, die einzeln gegeneinander verdrillt werden, z.B. nach dem Roebelprinzip. Solche kontinuierliche Drillleiter sind z.B. aus der EP 746 861 B1 bekannt und werden dabei maschinell und automatisiert mit Längen bis zu 2000m hergestellt und zur Verschiffung auf Trommeln aufgewickelt. Automatisierte Verdrillwerkzeuge zur Herstellung solcher Drillleiter gehen z.B. aus der DE 100 26 455 A1 oder der DE 100 27 564 A1 hervor. Drillleiter zeichnen sich insbesondere auch dadurch aus, dass diese ausreichend biegeweich sind, um zur Herstellung von Wicklungen gewickelt werden zu können. Weiters kann durch den Einsatz eines Drilleiters ein erhöhter Kupferquerschnitt ausgekreuzt verwickelt werden. Für Roebelstäbe ist es aus der AT 309 590 B auch bereits bekannt, die Verdrillung so vorzusehen, dass immer zwei benachbarte Einzelleiter gemeinsam verdrillt werden. Damit soll neben dem Ausgleich des Längsfeldes durch die Verdrillung auch das sich bereits schädlich machende Radialfeld innerhalb einer Nut kompensiert werden. Roebelstäbe, die nach wie vor hauptsächlich manuell hergestellt werden, indem Einzelleiter geringer Länge auf speziel- len Werkbänken durch einen Arbeiter manuell verdrillt werden, können auf diese Weise einfach hergestellt werden, auch wenn zwei benachbarte Teileiter gemeinsam verdrillt werden. Roebelstäbe werden jedoch nicht gewickelt, sondern es wird aus mehreren Roebelstäben eine Wicklung„gebaut", indem die Enden der Roebelstäbe entsprechend verbunden werden. The subject invention relates to a continuous drill ladder consisting of a plurality of individual, electrically insulated conductor part, and a method for producing such a drill guide. Known manner occur in transformers especially at the outer coils of the winding electromagnetic fields (transverse fields), which induce eddy currents in the winding conductors, which lead to eddy current losses. Eddy current losses reduce the efficiency of the transformer, but also lead to locally undesirable high temperatures, which in turn can lead to damage to the winding insulation. Through the use of known continuous twisted conductors such eddy current losses can be reduced. Drill ladders consist of a bundle of individual, insulated individual conductors, which are individually twisted against each other, e.g. according to the Roebel principle. Such continuous drill conductors are e.g. known from EP 746 861 B1 and are thereby machined and automated produced with lengths up to 2000m and wound up for shipping on drums. Automated twisting tools for making such twisted ladders are e.g. from DE 100 26 455 A1 or DE 100 27 564 A1. Drill ladder are characterized in particular by the fact that they are sufficiently bend soft to be wound for the production of windings can. Furthermore, through the use of a drill guide, an increased copper cross-section can be crossed out. For Roebel rods, it is already known from AT 309 590 B to provide the twist in such a way that always two adjacent individual conductors are twisted together. This should be compensated in addition to the compensation of the longitudinal field by the twist and the already damaging Radialfeld within a groove. Roebel rods, which are still mainly manufac- tured manually by manually twisting single-length individual wires on special workbenches, can be easily made in this way, even if two adjacent parts are twisted together. Roebel bars are not wound, but it is "built" of several Roebel bars a winding by the ends of the Roebel bars are connected accordingly.
Die Anforderungen an heutige Transformatoren steigen jedoch immer mehr, zum Einen hin- sichtlich Größe und Leistung und zum Anderen hinsichtlich Wirkungsgrad und Reduktion von Verlusten hervorgerufen z.B. durch Wirbelstromverluste. Speziell bei sehr großen leistungsstarken Transformatoren treten unerwünschte signifikante Wirbelstromverluste auf Grund der magnetischen Felder auf. Es ist daher eine Aufgabe der gegenständlichen Erfindung, einen Drillleiter anzugeben, mit dem die Wirbelstromverluste bei Einsatz des Drillleiters in einem Transformator reduziert werden können. However, the demands on today's transformers are increasing more and more, on the one hand with regard to size and power and on the other hand with regard to efficiency and reduction of losses caused eg by eddy current losses. Especially in the case of very large powerful transformers, undesirable significant eddy current losses due to the magnetic fields occur. It is therefore an object of the subject invention to provide a drill guide with which the eddy current losses can be reduced when using the drill guide in a transformer.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jeweils zwei oder mehrere ne- beneinander und/oder übereinander angeordnete Teilleiter zu einer Teilleitergruppe zusam- mengefasst und gemeinsam verdrillt sind. Dadurch dass nunmehr nicht ein einzelner Teilleiter verdrillt wird, sondern immer eine Teilleitergruppe bestehend aus mehreren einzelnen Teilleitern, werden die Wirbel Stromverluste weiter reduziert, da der erforderliche Kupferquerschnitt des Einzelleiters elektrisch aufgeteilt wird. Damit wird der Querschnitt eines einzelnen Teilleiters reduziert, womit durch die auftretenden elektro-magnetischen Felder weniger Wirbelströme induziert werden und damit die Wirbelstromverluste in einem Transformator bei Verwendung des erfindungsgemäßen Drillleiters reduziert werden können. Je kleiner die Querschnitt des Teilleiters, also je stärker der Kupferquerschnitt eines Einzelleiters geteilt wird, umso geringer werden dabei die Wirbelstromverluste. Bislang konnten in bekannten Verdrillwerkzeugen nur herkömmliche Drillleiter hergestellt werden, also mit nur jeweils einzelnen verdrillten Teilleitern. Es wurde aber bisher nicht in Erwägung gezogen, in einem kontinuierlichen Herstellprozess zur Herstellung eines kontinuierlichen Drillleiters, zwei oder mehrere benachbarte Teilleiter gemeinsam zu verdrillen, da einerseits bisher keine Notwendig dafür bestand und andererseits die bisherigen Verdrill- Werkzeuge bzw. Verdrillverfahren dafür gar nicht geeignet waren. Darüber hinaus wurde bisher wohl angenommen, dass sich ein Drillleiter mit mehreren gemeinsam verdrillten Teilleitern bei der nachfolgenden Wicklung zu einer Wicklung unerwünscht verhält und Probleme verursacht, z.B. durch nachträgliches Verschieben der einzelnen Teilleiter zueinander. Diese Probleme treten aber in der Praxis nicht auf, wie bei entsprechenden Versuchen festgestellt wurde. This object is achieved according to the invention in that in each case two or more sub-conductors arranged next to one another and / or one above the other are combined to form a sub-conductor group and are twisted together. Because now not a single conductor is twisted, but always a subconductor consisting of several individual sub-conductors, the vortex power losses are further reduced, since the required copper cross-section of the individual conductor is electrically divided. Thus, the cross section of a single subconductor is reduced, whereby less eddy currents are induced by the electro-magnetic fields occurring and thus the eddy current losses can be reduced in a transformer using the drill guide according to the invention. The smaller the cross section of the partial conductor, ie the more the copper cross section of a single conductor is divided, the smaller the eddy current losses become. Until now, only conventional twisted ladders could be produced in known twisting tools, ie with only individual twisted partial conductors. However, it has hitherto not been considered, in a continuous manufacturing process for producing a continuous twisted conductor, to twist together two or more adjacent partial conductors, since, on the one hand, there was no need for it and, on the other hand, the previous twisting tools or twisting methods were not at all suitable for this , Moreover, it has heretofore been well-known that a twisted conductor having a plurality of co-twisted sub-conductors in the subsequent winding to a winding undesirably behaves and causes problems, e.g. by subsequent displacement of the individual sub-conductors to each other. However, these problems do not occur in practice, as found in corresponding experiments.

Fig. 1 zeigt einen bekannten Drillleiter 1 bestehend aus einer Anzahl von elektrisch isolierten Teilleitern 2, die in zwei Teilleiterstapeln 3 angeordnet sind. Die Teilleiter 2 werden dabei bekanntermaßen so verdrillt, dass diese von der obersten in die unterste Lage wechseln. Um das Zusammenhalten des Teilleiterbündels zu einem Drillleiter 1 zu gewährleisten, kann auch eine Umwicklung 4 durch ein Webband, einen Papierstreifen oder ähnlichem vorgesehen sein. 1 shows a known drill conductor 1 consisting of a number of electrically insulated partial conductors 2, which are arranged in two partial conductor stacks 3.

Ein erfindungsgemäßer Drillleiter 10 ist in Fig. 2 dargestellt, der aus einer Vielzahl von ein- zelnen elektrisch isolierten Teilleitern 1 1 besteht. Bei diesem Drillleiter 10 werden jeweils zwei nebeneinander liegende Teilleiter 1 1 zu einer Teilleitergruppe 12 zusammengefasst und gemeinsam verdrillt.„Nebeneinander" bedeutet hierbei, dass die Teilleiter 11 an ihrer schmalen Seitenfläche aneinander liegend angeordnet sind. Es wird somit die Teilleitergruppe 12 gegenüber dem restlichen Teilleiterbündel verdrillt und nicht ein einzelner Teilleiter wie bis- her im Stand der Technik. Eine solche Teilleitergruppe 12 kann dabei auch mehr als zwei einzelne Teilleiter 1 1 umfassen. Ein Querschnitt durch einen solchen Drillleiter 10 mit sieben Teilleitergruppen 12-ι bis 127, bestehend aus jeweils zwei einzelnen nebeneinander angeordneten Teilleitem 11 ist in Fig. 3 dargestellt. Das Teilleiterbündel kann dabei wieder mit einer Umwicklung 13, z.B. zum Schutz der Teilleiter 11 beim Transport oder zur Stabilisierung des Teileiterbündels, umgeben sein. An inventive drill 10 is shown in Fig. 2, which consists of a plurality of individual electrically isolated part conductors 1 1. In this drill wire 10, in each case two adjacent sub-conductors 1 1 are combined to form a sub-conductor group 12. "Side by side" means that the sub-conductors 11 are arranged adjacent to each other on their narrow side surface twisted and not a single conductor like bis- forth in the art. such conductor group 12, more than two individual conductor 1 1 may include it. a cross section through such a drill head 10 having seven conductor groups 12 ι to 12 7, consisting of two individual juxtaposed subconductors 11 are shown in Fig. 3. The subconductor bundle can be surrounded again with a winding 13, eg for the protection of the subconductors 11 during transport or for stabilizing the subconductor bundle.
In einer anderen möglichen Ausgestaltung des erfindungsgemäßen Drillleiters 10 werden zwei einzelne Teilleiter 11 übereinander angeordnet und zu einer Teilleitergruppe 12, die dann wiederum verdrillt wird, zusammengefasst.„Übereinander" bedeutet hierbei, dass die Teilleiter 1 1 an ihrer breiten Seitenfläche aneinander liegend angeordnet sind. Eine solche Teilleitergruppe 12 kann dabei auch mehr als zwei einzelne übereinander angeordnete Teilleiter 1 1 umfassen. Ein Querschnitt durch einen solchen Drillleiter 10 mit fünf Teilleitergruppen 12T bis 125, bestehend aus jeweils zwei übereinander angeordneten einzelnen Teilleitern 1 1 ist in Fig. 3 dargestellt. Das Teilleiterbündel kann dabei wieder mit einer Umwicklung 13, z.B. zum Schutz der Teilleiter 1 1 beim Transport oder zur Stabilisierung des Teileiterbündels, umgeben sein. In another possible embodiment of the inventive twisted conductor 10, two individual sub-conductors 11 are arranged one above the other and combined to form a sub-conductor group 12, which in turn is twisted. "Superimposed" here means that the sub-conductors 1 1 are arranged adjacent to one another on their broad side surface. Such a sub-conductor group 12 may also comprise more than two individual sub-conductors 1 1 arranged one above the other, a cross-section through such a twisted conductor 10 having five sub-conductor groups 12T to 12 5 consisting of two individual sub-conductors 1 1 arranged one above the other. The subconductor bundle can again be surrounded by a winding 13, for example for protecting the subconductor 11 during transport or for stabilizing the subconductor bundle.
Ebenso ist es denkbar, eine Teilleitergruppe 12 aus mehreren neben- und übereinander angeordneten Teilleitem 11 zu bilden, wie in Fig. 6 angedeutet, wobei wiederum die ganze Teilleitergruppe 12 verdrillt wird. Im Beispiel nach Fig. 6 sind jeweils vier einzelne Teilleiter 1 1 zu einer Teilleitergruppe 12-ι bis 125 nebeneinander und übereinander angeordnet. It is likewise conceivable to form a subconductor group 12 from a plurality of subconductors 11 arranged next to one another and above one another, as indicated in FIG. 6, in which case again the entire subconductor group 12 is twisted. In the example of FIG. 6 four individual sub-conductors 1 1 to a sub-conductor group 12-ι to 12 5 are arranged side by side and one above the other.
