Definitions
- the invention relates to an electrically conductive wire according to the preamble of patent claim 1 and to a method for producing the wire.
- a designated as winding wire wire goes out of the DE 197 03 161 A1 out. It is surrounded over its entire surface by an insulating varnish, which is preferably applied in several thin individual layers.
- the insulating varnish must be baked, at the same time solvent must be removed environmentally friendly.
- a baked enamel is applied intermittently, and in particular as in several layers. The baked enamel is surrounded by an insulation liner.
- a wire as described above is used, for example, as a flat wire of rectangular cross section for producing 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 easier than the wire described above.
- practice has shown that such a wire is not resistant to corrosion in the long term. Rather, during the operation of an electrical device equipped with such a wire, conductive copper sulfide is formed by corrosive constituents of the oil used as the coolant, thereby damaging the layer of paper. An appropriately constructed winding is then quickly unusable, so that the associated device stops working.
- the entrance-mentioned FR 2 805 657 describes an electrical conductor for transformers, which is surrounded by two layers of paper, which are glued to the conductor and each other and also have adhesive material on the outer surface.
- the two layers of paper consist of adhesive tapes wrapped around the conductor.
- the first layer which directly surrounds the conductor is an adhesive layer which bonds the overlying paper layer to the conductor.
- the invention has for its object to make the wire described above so that it has a further simple production improved corrosion resistance.
- 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.
- 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.
- 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.
- an epoxy resin is particularly suitable. It is also possible to use alkyl resins or polyesterimides, also in modified form.
- 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.
- a polymeric material paper tape 9 may again consist of commercially available insulating paper.
- 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.
- 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.
- 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.
Abstract
Description
Die Erfindung bezieht sich auf einen elektrischleitfähigen Draht gemäß dem Oberbegriff des Patentanspruchs 1 sowie auf ein Verfahren zur Herstellung des Drahtes.The invention relates to an electrically conductive wire according to the preamble of
Ein solcher Draht geht aus
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 Polyvinylacetat verwendet, das ebenso wie andere Lacke starklösungsmittelhaltig 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
Ein als Wicklungsdraht bezeichneter Draht geht aus der
En 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 im 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 producing 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 easier than the wire described above. However, practice has shown that such a wire is not resistant to corrosion in the long term. Rather, during the operation of an electrical device equipped with such a wire, conductive copper sulfide is formed by corrosive constituents of the oil used as the coolant, thereby damaging the layer of paper. An appropriately constructed winding is then quickly unusable, so that the associated device stops working.
Die eingangserwähnte
Der Erfindung liegt die Aufgabe zugrunde, den eingangsbeschriebenen Draht so zu gestalten, daß er bei weiter einfacher Herstellung eine verbesserte Korrosionsfestigkeit hat.The invention has for its object to make the wire described above so that it has a further simple production improved corrosion resistance.
Diese Aufgabe wird entsprechend dem kennzeichnenden Merkmal des Patentanspruchs 1 gelöst.This object is achieved according to the characterizing feature of
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 den selben 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:
- Auf einen vorgefertigten
flachen Draht 1 mit rechteckigem Querschnitt (Fig. 2 ), der vorzugsweise aus Kupfer besteht, wird in einerBeschichtungsvorrichtung 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 denDraht 1 aufgetragen werden. DieBeschichtungsvorrichtung 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 acoating 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 thewire 1. Thecoating 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
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
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
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.
