Description

Verfahren zur Herstellung der Isolation für die Wicklungen elektrischer Spulen Man hat bereits Spulen für elektrische Zwecke aus einem mit Oxydüberzug versehenen Aluminiumdraht hergestellt und insbesondere die fertigen Spulen zur Herbeiführung der Oxydation des Drahtes in eine oxydierende Flüssigkeit eingeführt. Dieses Verfahren ist äußerst einfach, da Aluminium leicht oxydiert und Aluminiumoxyd seine gute Isoliereigenschaft besitzt. Es ist aber nicht anwendbar, wenn es sich um elektrische Leiter handelt, deren Oxydschicht nicht isolierend wirkt. Nun wurde bereits, vorgeschlagen, als Rostschutzfarbe ein Aluminium-Silicium-Pigment zu verwenden, dem als Ausgangsmaterial eine Aluminium-Silicium-Legierung dient. Wird dieses Pigment auf ein Metall aufgetragen und dann im Trockenofen einer verhältnismäßig hohen Temperatur ausgesetzt, so tritt eine innige Verbindung der Pigmentschicht mit dem Metall ein. ),a diese Schicht eine hohe elektrische Isoliereigenschaft hat, sehr geschmeidig ist und eine gute Wärmeleitfähigkeit besitzt, so kann diese in vorteilhaften Weise zur Isolierung elektrischer Leiter verwendet werden.Process for the production of the insulation for the windings electrical Coils One already has coils for electrical purposes made from an oxide coating Manufactured aluminum wire and in particular the finished coils for bringing about The oxidation of the wire is introduced into an oxidizing liquid. This method is extremely simple, since aluminum oxidizes easily and aluminum oxide has good insulating properties owns. However, it is not applicable when it comes to electrical conductors, whose oxide layer does not have an insulating effect. Well it has already been proposed as Anti-rust paint to use an aluminum-silicon pigment as the starting material an aluminum-silicon alloy is used. This pigment is applied to a metal and then exposed to a relatively high temperature in the drying oven, so occurs an intimate connection of the pigment layer with the metal. ), a this layer has a high electrical insulating property, is very pliable, and is good Has thermal conductivity, it can be used in an advantageous manner for insulation electrical conductors are used.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung der Isolation für die Wicklungen elektrischer Spulen, bei dem der Leiter mit einer oxydierenden Flüssigkeit behandelt wird. Erfindungsgemäß wird der elektrische Leiter mit einem Anstrich eines Aluminium-Silicium-Pigments versehen und getrocknet. Hierauf wird der Leiter erneut mit einem Aluminium-Silicium-Pigment überstrichen, feucht in Spulenform aufgewickelt, in einem Drwcktemperaturvorgang oxydiert und bei hoher Temperatur getrocknet. Das Oxydieren findet zweckmäßig in einem Autold.aven statt. Bei einer derartigen Spule wird die erforderliche Isolation durch eine äußerst dünne Schicht erzeugt, so daß sie gegenüber anders ;gearteten Spulen :einen sehr kleinen Raum einnimmt.The invention relates to a method for producing the insulation for the windings of electrical coils, in which the conductor with an oxidizing Liquid is treated. According to the invention, the electrical conductor with a Painted with an aluminum-silicon pigment and dried. Then will the conductor was again coated with an aluminum-silicon pigment, wet in the form of a coil wound up, oxidized in a pressure temperature process and at high temperature dried. The oxidation takes place expediently in an autoldave. At a Such a coil is the required insulation by an extremely thin layer generated so that they are different from that of coils: a very small space occupies.

Hinzu kommt, daß durch die gute Wärmeleitfähigkeit der Isolation die Spule höher belastbar ist, weil die in den inneren Windungen entstehende Wärme ohne iweiteres durch die gute Wärmeleitfihiglkeit nach außen geführt wird. Ferner ist an sich die Spule höher belastbar, weil die Isolation in der Lage ist, dauernd hohe Temperaturen auszuhalten.In addition, due to the good thermal conductivity of the insulation, the Coil is more resilient because it is in the inner turns arising Heat is conducted to the outside without any further thanks to the good thermal conductivity. Furthermore, the coil itself is more resilient because the insulation is able to withstand high temperatures all the time.

Zweckmäßig twerden die Spulenwindungen vor dein Oxydationsprozeß auf den Spulenkörper aufgebracht, wobei letzterer aus einem beim Drucktemperaturtvorgang leicht oxydierenden Metall, z. B. Aluminium, oder aber aus einem anderen Metall mit einer Aluminiumschicht besteht. Durch die Oxydation der Aluminiumschicht wird eine gute Isolation zwischen Spulenwindung und Spulenkörper und gleichzeitig ein guter Zusammenhalt erzielt.The coil windings are expediently opened before the oxidation process applied to the bobbin, the latter from a print temperature process easily oxidizing metal, e.g. B. aluminum, or made of another metal with an aluminum layer. The oxidation of the aluminum layer is good insulation between coil winding and coil body and at the same time good cohesion achieved.
