Description

Die Hauptpatentanmeldung betrifft ein Verfahren zur Herstellung von imprägnierten, glimmerhaltigen Isolationen für elektrische Leiter, die durch Bewickeln der Leiter mit Feinglimmerfolie und nachfolgendes Imprägnieren mit Kunstharz gebildet sind. Gemäß der Erfindung der Hauptpatentanmeldung wird die Feinglimmerfolie vor dem Imprägnieren kurzzeitig mit einer Flüssigkeit oder ihrem Dampf in Berührung gebracht und einem Vorformungsvorgang unterworfen, wobei ihre endgültigen Abmessungen durch Ausdampfen der Flüssigkeit fixiert werden.The main patent application relates to a process for the production of Impregnated, mica-containing insulation for electrical conductors that are wound by winding the conductor is formed with fine mica foil and subsequent impregnation with synthetic resin are. According to the invention of the main patent application, the fine mica film is before briefly in contact with a liquid or its vapor after impregnation brought and subjected to a pre-forming process, with their final dimensions fixed by evaporation of the liquid.

Nach einer bevorzugten Durchführungsform des in der Hauptpatentanmeldung beschriebenen Verfahrens werden die Leiter mit der vorgeformten Isolation vor dem Imprägnieren in die Nuten elektrischer Maschinen eingebaut und in der elektrischen Maschine imprägniert. In manchen Fällen, insbesondere wenn es sich um große elektrische Maschinen handelt, stehen keine geeigneten Einrichtungen (Autoklavs) zur Verfügung, die die Maschine oder ihren Stator bzw. Rotor als Ganzes aufnehmen können und so ein Imprägnieren der bereits in die elektrische Maschine eingebauten Isolation erlauben würden.According to a preferred embodiment of the one in the main patent application The conductors with the preformed insulation before the process described Impregnation built into the grooves of electrical machines and in the electrical Machine impregnated. In some cases, especially when it is large electrical Machines, no suitable facilities (autoclaves) are available, that can accommodate the machine or its stator or rotor as a whole, and so on allow the insulation already built into the electrical machine to be impregnated would.

Aufgabe der vorliegenden Erfindung ist es, eine besonders zweckmäßige Durchführungsform des Verfahrens nach der Hauptpatentanmeldung anzugeben, die die Anwendung des Verfahrens auch bei großen elektrischen Maschinen gestattet. Zu diesem Zweck werden gemäß der Erfindung die Leiter mit der vorgeformten Isolation mit Kunstharz imprägniert, dann in die .Nuten elektrischer- Maschinen eingebaut...und in der elektrischen Maschine wird die mit Kunstharz imprägnierte Isolation gehärtet.The object of the present invention is to provide a particularly useful one Specify the form of implementation of the procedure after the main patent application, which the The method can also be used for large electrical machines. To this According to the invention, the purpose is the conductors with the preformed insulation with synthetic resin impregnated, then built into the .nuts of electrical machines ... and in the electrical Machine, the insulation impregnated with synthetic resin is hardened.

Die nach diesem Verfahren schon fertig isolierten, mit Harz getränkten bzw. imprägnierten Leiter weisen eine ausreichende Flexibilität auf, so daß sie bei Einbau in die Nuten elektrischer Maschinen noch verformt werden können. Die im übrigen nach dem Vorschlag der Hauptpatentanmeldung hergestellte Isolation widersteht den beim Einbau auftretenden erheblichen Beanspruchungen anstandslos. Es steht natürlich nichts im Wege, die vorliegende Erfindung auch für kleine elektrische Maschinen anzuwenden.Those already isolated by this process and soaked with resin or impregnated conductors have sufficient flexibility so that they can still be deformed when installed in the grooves of electrical machines. the otherwise, according to the proposal of the main patent application, insulation is resistant the considerable stresses occurring during installation without any problem. Of course it is nothing in the way of the present invention for small electrical machines apply.
