Band-Spule für TransformatorenTape reel for transformers
Die Erfindung betrifft eine Band-Spule für Transformatoren, insbesondere Hochspannungstransformatoren, mit einer elektrisch leitenden Folie, deren Windungen (Leiterlagen) durch eine bandförmige Isolierbahn (Isolierlagen) elektrisch voneinander getrennt sind.The invention relates to a tape reel for transformers, especially high-voltage transformers, with an electrically conductive film, the turns (conductor layers) are electrically separated from one another by a strip-shaped insulating strip (insulating layers).
Spulen dieser Art sind bereits seit Jahrzehnten bekannt und finden vor allem wegen ihrer guten Wickelraumausnutzung, ihrer relativ hohen Kurzschlußfestigkeit und der höheren elektrischen Belastbarkeit von Folien oder Bändern gegenüber Drähten Verwendung; vergleiche hierzu beispielsweise die DOS 1 763 630 und das DBP 911 292. Für Hochspannungstransformatoren in gedrungener Bauweise erschien die Folienwickeltechnik bisher, allerdings weniger günstig, da durch keine der bislang angewandten Wickeltechniken oder Materialbearbeitungen Lufteinschlüsse zwischen Leiterfolie und Isolierlage vermeidbar sind und damit die Gefahr schädlicher Koronaentladungen besteht.Coils of this type have been known for decades and find mainly because of their good utilization of winding space, their relatively high short-circuit strength and the higher electrical load capacity of foils or tapes compared to wires use; compare for example the DOS 1 763 630 and the DBP 911 292. For high-voltage transformers Foil wrapping technology has appeared in a compact design so far, but less inexpensive, as there are no air pockets between the conductor foil due to any of the winding techniques or material processing used to date and insulating layer can be avoided and there is therefore a risk of harmful corona discharges.
Wollte man die Entladungsgefahr bei den zwischen benachbarten Windungen der Leiterfolie herrschenden hohen Spannungen vermindern, so bliebe natürlich die Möglichkeit, die Feldstärken am Ort der Folienoberfläche durch Verdickung der Isolierlagen zu senken. Eine derartige Maßnahme wäre jedoch insbesondere deshalb unbefriedigend,If you wanted to reduce the risk of discharge between neighboring The high voltages prevailing in the turns of the conductor foil, the possibility would of course remain to reduce the field strengths at the location of the film surface by thickening the insulating layers. Such a measure however, would be particularly unsatisfactory if

weil Folienwicklungen gerade im Hinblick auf ihren raumsparend hohen Füllfaktor und ihre hohe Strombelastbarkeit bevorzugt eingesetzt werden.because foil wraps, especially with regard to their space-saving high fill factor and their high current carrying capacity are preferred.
Der Erfindung liegt die Aufgabe zugrunde, eine Spule der eingangs genannten Art so zu verbessern, daß sie bei guter Wickelraumausnutzung dennoch koronafest bleibt, und schlägt hierzu vor, daß die Isolierlagen beidseitig metallisiert sind.The invention is based on the object of improving a coil of the type mentioned at the outset so that it can with good The utilization of the winding space remains corona-proof, and suggests that the insulating layers are metallized on both sides are.
Dem erfindungsgemäßen Lösungsvorschlag liegt die folgende Überlegung zugrunde: Anstatt nach einer Vervollkommnung von Wickel- oder Bearbeitungsverfahren zu suchen, welche die unerwünschten Lufteinschlüsse verhindern könnten, werden die bei der üblichen Wicklung bestehenden Lufteinschlüsse durchaus zugelassen. Diese Einschlüsse befinden sich gemäß der Erfindung allerdings nicht zwischen Isolierlage und Leiterlage sondern in der Kontaktfläche zweier Leiter, der Leiterfolie einerseits und der Metallisierung der Isolierlage andererseits. Der Übergang Leiter-Isolierlage ist dagegen durch. die.Metallisierungstechnik gänzlich luftfrei gehalten. Der Gefahr von Koronaentladungen wird also nicht durch ein Verhindern oder Beseitigen sondern durch ein Verschieben der Luftblasen in das Leiterinnere, in dem bekanntlich keine Potentialdifferenzen herrschen und daher die eingeschlossene Luft elektrisch nicht belastet wird, höchst einfach entgegengetreten.The proposed solution according to the invention is as follows Consideration: Instead of looking for a perfecting of winding or machining processes, which the could prevent unwanted air inclusions, the air inclusions existing in the usual winding quite admissible. According to the invention, however, these inclusions are not located between insulating layers and conductor layer but in the contact area of two conductors, the conductor foil on the one hand and the metallization of the Isolation layer on the other hand. The transition between conductor and insulation layer is through. The metallization technology is completely free of air held. The danger of corona discharges is therefore not caused by preventing or eliminating, but by a Moving the air bubbles into the inside of the conductor, in which, as is well known, there are no potential differences and therefore the enclosed air is not electrically charged, very simply counteracted.
Im Einzelfall kann man bei einer erfindungsgemäßen Band-Spule auch von der Verwendung einer besonderen Leiterfolie absehen, wenn die Leitereigenschaften der beidseitigen Metallisierung. allen Anforderungen genügen, insbesondere wenn der Metallisierungsquerschnitt für die Stromleitung ausreicht. DieseIn individual cases, one can also refrain from using a special conductor foil with a tape reel according to the invention, if the conductor properties of the metallization on both sides. meet all requirements, especially if the metallization cross-section is sufficient for the power line.

Spulenausführung hat den Vorzug, besonders einfache Wickelverfahren zu ermöglichen, da ein gleichzeitiges Bewickeln mit Bahnen verschiedener Festigkeit, Breite und Flexibilität entfällt.Coil design has the advantage of enabling particularly simple winding processes, since a simultaneous one Wrapping with strips of different strength, width and flexibility is not necessary.
Ein besonderes Anwendungsgebiet der Erfindung ist der Einsatz in Stromversorgungsanlagen von Leitungsrohren, insbesondere Wanderfeldröhren in Nachrichtensatelliten. Man benötigt dort nämlich Hochspannungstransformatoren kleiner Bauart mit möglichst .geringem Raumbedarf und dennoch höchster Zuverlässigkeit.A particular field of application of the invention is Use in power supply systems of line pipes, in particular traveling wave tubes in communications satellites. You need small high-voltage transformers there Design with the smallest possible space requirement and yet the highest level of reliability.
Anhand eines in der Figur der Zeichnung nur schematisch dargestellten Ausführungsbeispiels für einen Hochspannungstransformator soll nun die Erfindung näher erläutert werden.On the basis of an exemplary embodiment for a high-voltage transformer, which is only shown schematically in the figure of the drawing the invention will now be explained in more detail.
Die Figur zeigt eine erfindungsgemäße Band-Spule in einer teilweise'weggebrochenen Seitenansicht. Die Spule besteht im einzelnen aus einer Metallfolie 1, beispielsweise aus Cu oder Al, und einer beidseitig mit' einer Metallisierung versehenen Isolierlage 3, ebenfalls einer Folie. Die ■ Metallisierung 2 ist der Isolierfolie 3 aufgedampft; sie kann ebenfalls aus Cu bestehen. Für die Isolierfolie 3 können hierzu übliches Isolierpapier oder eine Kunststoffolie verwendet werden, die bekanntlich bei geringeren Dicken gleich hohe Isolationswerte wie Papier erbringt. Die elektrischen Anschlüsse der Wicklung sind nur als Zuführungen 4, 5 angedeutet. Ein Schutz- und Isoliermantel 6 umgibt die gesamte Spulenanordnung.The figure shows a tape reel according to the invention in a partially broken away side view. The coil is made in detail from a metal foil 1, for example from Cu or Al, and one on both sides with a metallization provided insulating layer 3, also a film. The ■ metallization 2 is vapor-deposited on the insulating film 3; she can also consist of Cu. For this purpose, conventional insulating paper or a plastic film can be used for the insulating film 3 are used, which is known to provide the same high insulation values as paper at lower thicknesses. The electrical connections of the winding are only indicated as leads 4, 5. A protective and insulating jacket 6 surrounds the entire coil arrangement.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. So kann unter geeigneten Bedingungen die Leiterfolie eingespart werden. Darüberhinaus kann ganzThe invention is not limited to the illustrated embodiment. So can under suitable conditions the conductor foil can be saved. In addition, it can be quite
