Description

Die Erfindung bezieht sich auf einen elektrisch leitfähigen Draht, welcher von einer Schicht aus Papier umgeben ist, zur Herstellung einer in einem elektrischen Gerät anzuordnenden Wicklung, in welchem sich ein die Wicklung umgebendes, als Kühlmedium dienendes Öl befindet sowie auf ein Verfahren zur Herstellung des Drahtes.The invention relates to an electrically conductive wire, which is surrounded by a layer of paper, for producing a winding to be arranged in an electrical device, in which there is a surrounding the winding, serving as a cooling medium oil and a method for producing the wire ,

Es sind sogenannte, mit Papier isolierte Drilleiter mit aus Drähten bestehenden Teilleitern für in Öl betriebene elektrische Geräte bekannt, bei denen die Drähte der Teilleiter lackiert sind. Als Lack wird beispielsweise Polyvinylacetal verwendet, das ebenso wie andere Lacke stark lösungsmittelhaltig ist. Ein solcher Lack wird in mehreren Schichten auf den Draht aufgebracht. Er muß danach in einem speziellen Ofen eingebrannt werden, wobei gleichzeitig das Lösungsmittel umweltfreundlich entfernt werden muß. Ein dafür verwendbarer Ofen ist beispielsweise in der DE-PS 1 242 511 beschrieben. Das Aufbringen des Lacks mit den nachfolgenden Arbeitsgängen Einbrennen und Lösungsmittelentfernen ist aufwendig und auf Drähte mit relativ kleinen Abmessungen beschränkt.There are known so-called paper-insulated twisted conductors with sub-conductors made of wires for oil-operated electrical appliances in which the wires of the partial conductors are painted. For example, polyvinyl acetal is used as the paint, which, like other paints, is highly solvent-containing. Such a paint is applied in several layers on the wire. He must then be burned in a special oven, at the same time the solvent must be removed environmentally friendly. A suitable oven is for example in the DE-PS 1 242 511 described. The application of the paint with the subsequent operations burn-in and solvent removal is complex and limited to wires with relatively small dimensions.

Ein Draht, wie er eingangs beschrieben ist, wird beispielsweise als Flachdraht mit rechteckigem Querschnitt zur Herstellung von Wicklungen für Transformatoren und elektrische Maschinen verwendet. Der Draht ist gemäß dem seit langen Jahren bekannten Stand der Technik von einer Schicht aus Papier als Isolierung umgeben, die auch als Abstandshalter zu benachbarten, in einer Wicklung angeordneten Windungen des Drahtes dient. Die Herstellung eines solchen Drahtes und einer daraus gefertigten Wicklung ist gegenüber dem in Vorangehenden geschilderten Draht wesentlich einfacher. Die Praxis hat jedoch gezeigt, daß ein derartiger Draht auf Dauer nicht korrosionsbeständig ist. Es wird vielmehr während des Betriebes eines mit einem solchen Draht ausgerüsteten elektrischen Geräts durch korrosive Bestandteile des als Kühlmittel verwendeten Öls leitfähiges Kupfersulfid gebildet, durch welches die Schicht aus Papier beschädigt wird. Eine entsprechend aufgebaute Wicklung wird dann schnell unbrauchbar, so daß das zugehörige Gerät nicht mehr funktioniert.A wire as described above is used, for example, as a flat wire of rectangular cross-section for the production of windings for transformers and electrical machines. The wire is surrounded according to the known for many years prior art of a layer of paper as insulation, which also serves as a spacer to adjacent, arranged in a winding turns of the wire. The production of such a wire and a winding made therefrom is much simpler than the wire described above. However, practice has shown that such a wire is not resistant to corrosion in the long term. It is rather during operation of one with such Wire-coated electrical device formed by corrosive constituents of the oil used as a coolant conductive copper sulfide, through which the layer of paper is damaged. An appropriately constructed winding is then quickly unusable, so that the associated device stops working.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs beschriebenen Draht so zu gestalten, daß er bei weiter einfacher Herstellung eine verbesserte Korrosiönsfestigkeit hat.The invention has for its object to make the wire described above so that it has an improved Korrosiönsfestigkeit further simple production.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Draht von einer denselben lückenlos bedeckenden Schicht aus einem vernetzten polymeren Werkstoff umgeben ist, über welcher die Schicht aus Papier angeordnet ist.This object is achieved according to the invention in that the wire is surrounded by a same gapless covering layer of a crosslinked polymeric material, over which the layer of paper is arranged.

Der polymere Werkstoff kann mit in der Lackiertechnik üblichen Verfahren und Vorrichtungen direkt auf den Draht aufgebracht und anschließend vernetzt werden, und zwar auch auf Leiter mit größeren Abmessungen. Die Schicht aus Papier kann dann in üblicher Technik um den Draht herumgeformt werden. Ein solcher polymerer Werkstoff enthält nur relativ wenig Lösungsmittel, so daß keine aufwendige Nachbehandlung erforderlich ist. Das gilt bezüglich des Werkstoffs auch dann, wenn derselbe auf ein Band aus Papier aufgetragen wird, das anschließend so um den Draht herumgewickelt wird, daß der polymere Werkstoff am Draht anliegend denselben lückenlos umgibt. Außerdem ist der polymere Werkstoff gegenüber handelsüblichen Ölen auf Dauer beständig, so daß mit demselben aufgebaute Wicklungen für mit Öl gekühlte Geräte eine wesentlich erhöhte Lebensdauer haben.The polymeric material can be applied directly to the wire and then crosslinked using conventional methods and apparatuses in the painting industry, including on conductors of larger dimensions. The layer of paper can then be formed around the wire in conventional technology. Such a polymeric material contains only relatively little solvent, so that no expensive post-treatment is required. This is true with respect to the material, even when it is applied to a band of paper, which is then wrapped around the wire so that the polymeric material adjacent to the wire surrounds the same gapless. In addition, the polymeric material is resistant to commercial oils over time, so that with the same constructed windings for oil cooled devices have a significantly increased life.

Ein Draht nach der Erfindung wird in einer ersten Variante beispielsweise wie folgt hergestellt:A wire according to the invention is produced in a first variant, for example, as follows:

Auf einen vorgefertigten flachen Draht 1 mit rechteckigem Querschnitt (Fig. 2), der vorzugsweise aus Kupfer besteht, wird in einer Beschichtungsvorrichtung 2 rundum eine Schicht 3 (Fig. 3) aus einem vernetzbaren, polymeren Werkstoff aufgetragen, und zwar in mindestens einer Lage. Mit Vorteil besteht die Schicht 3 aus zwei Lagen aus dem polymeren Werkstoff, die nacheinander mit einer Dicke von jeweils beispielsweise 0,01 mm auf den Draht 1 aufgetragen werden. Die Beschichtungsvorrichtung 2 kann eine in der Lackiertechnik übliche Vorrichtung sein.On a prefabricated flat wire 1 with rectangular cross section ( Fig. 2 ), which preferably consists of copper, is coated in a coating device 2 around a layer 3 (FIG. Fig. 3 ) applied from a crosslinkable polymeric material, in at least one layer. Advantageously, the layer 3 of two layers of the polymeric material, which are successively applied with a thickness of, for example, 0.01 mm on the wire 1. The coating device 2 may be a conventional device in painting technology.

Der so beschichtete Draht 1 wird anschließend in eine Vernetzungseinrichtung 4 geführt, in welcher der polymere Werkstoff durch Wärmezufuhr vernetzt wird. In Abhängigkeit von den Abmessungen bzw. dem Querschnitt des Drahtes 1 erfolgt die Vernetzung beispielsweise bei einer zwischen 300 °C und 350 °C liegenden Temperatur. Die Schicht 3 haftet danach fest am Draht 1. Abschließend wird in einer Vorrichtung 5 eine Schicht 6 aus Papier um den Draht 1 herumgeformt. Dazu kann beispielsweise ein Band aus handelsüblichem Isolierpapier um den Draht 1 herumgewickelt werden.The thus coated wire 1 is then guided into a cross-linking device 4, in which the polymeric material is crosslinked by supplying heat. Depending on the dimensions or the cross section of the wire 1, the crosslinking takes place, for example, at a temperature between 300 ° C and 350 ° C temperature. The layer 3 then adheres firmly to the wire 1. Finally, in a device 5, a layer 6 of paper around the wire 1 is formed around. For this purpose, for example, a band of commercially available insulating paper can be wound around the wire 1.

Als polymerer Werkstoff ist besonders ein Epoxydharz geeignet. Es können auch Alkylharze oder Polyesterimide, auch in modifizierter Form, eingesetzt werden.As the polymeric material, an epoxy resin is particularly suitable. It is also possible to use alkyl resins or polyesterimides, also in modified form.

In einer zweiten Variante zur Herstellung des Drahtes nach der Erfindung kann ein Band 7 eingesetzt werden, das aus einem vorzugsweise einseitig auf seiner ganzen Oberfläche mit einer Schicht 8 aus einem polymeren Werkstoff versehenen Papierband 9 besteht. Grundsätzlich wäre es auch möglich, das Band 7 beidseitig mit polymerem Werkstoff zu beschichten. Der polymere Werkstoff kann der gleiche, wie oben angegeben sein. Das Papierband 9 kann wieder aus handelsüblichem Isolierpapier bestehen. Durch diese Variante wird die Herstellung des Drahtes weiter vereinfacht, da beide Schichten - polymerer Werkstoff einerseits und Papier andererseits - in nur einem Arbeitsgang auf den Draht 1 aufgebracht werden.In a second variant for the production of the wire according to the invention, a tape 7 can be used, which consists of a preferably unilaterally provided on its entire surface with a layer 8 of a polymeric material paper tape 9. In principle, it would also be possible to coat the band 7 on both sides with polymeric material. The polymeric material may be the same as stated above. The paper tape 9 may again consist of commercially available insulating paper. By this variant, the production of the wire is further simplified since Both layers - polymeric material on the one hand and paper on the other - are applied to the wire 1 in only one operation.

Das Band 7 wird so um den Draht 1 herumgewickelt, daß sich eine der Schicht 3 entsprechende, den Draht 1 lückenlos umgebende Schicht 8 aus polymerem Werkstoff ergibt. Dazu kann das Band 7 Stoß an Stoß um den Draht 1 herumgewickelt werden. Es wird jedoch in bevorzugter Ausführungsform mit Überlappung um den Draht 1 herumgewickelt. Das ist in Fig. 5 durch gestrichelt eingezeichnete Linien angedeutet.The tape 7 is wound around the wire 1, that results in a corresponding layer 3, the wire 1 surrounding gap 8 of polymeric material. For this purpose, the band 7 can be wound around the wire 1 in shock. However, in a preferred embodiment, it is wrapped around the wire 1 with overlap. Is in Fig. 5 indicated by dashed lines.

Der polymere Werkstoff kann auch bei dieser Variante der Herstellung des Drahtes abschließend vernetzt werden. Auf diesen Schritt kann aber auch verzichtet werden, weil Wicklungen aus einem solchen Draht nach ihrer Fertigstellung durch Erwärmung bei Temperaturen getrocknet werden, die auch zur Vernetzung des polymeren Werkstoffs ausreichen.The polymeric material can also be finally crosslinked in this variant of the production of the wire. But this step can also be dispensed with, because windings are dried from such a wire after its completion by heating at temperatures that are sufficient for the crosslinking of the polymeric material.
