Description
Verfahren zur isolierenden Auskleidung von Wickelräumen elektrischer Maschinen und Geräte, insbesondere von Nuten der Ständer und Läufer elektrischer Maschinen Die isolierende Auskleidung von Wickelräumen elektrischer Maschinen und Geräte erfolgt bisher im allgemeinen in der Weise, daß in die Wickelräume Folien, Pappen od. dgl. aus Isolierstoff eingelegt werden. Diese Folien, Pappen od. dgl. werden aus größeren Bogen oder Streifen ausgestanzt oder ausgeschnitten und mit oder ahne Verformung in die Wickelräume eingedrückt oder sonstwie eingeführt.Process for the insulating lining of winding rooms electrical Machines and devices, in particular of grooves of the stator and rotor electrical Machines The insulating lining of changing rooms for electrical machines and Devices are generally done in such a way that foils in the changing rooms Cardboard or the like made of insulating material are inserted. These foils, cardboard or the like. are punched or cut out of larger sheets or strips and with or pressed or otherwise inserted into the changing rooms without deformation.
Weiter ist es bekannt, Nutenisolationen elektrischer Maschinen in den jeweils gewünschten Formen auf der Strangpresse aus thermoplastischen Isolierstoffen .herzustellen. Das Ausstanzen bzw. Ausschneiden wird hierdurch vermieden. Andererseits erfordert dieses Verfahren aber besondere, den jeweiligen Wickelräumen entsprechende Preßformen, und es müssen auch hierbei die isolierenden Auskleidungen einzeln eingedrückt oder sonst-wie eingeführt werden.It is also known to use slot insulation in electrical machines the desired shapes on the extrusion press made of thermoplastic insulating materials .produce. This avoids punching or cutting out. on the other hand However, this procedure requires special ones that are appropriate for the respective changing rooms Compression molds, and here too the insulating linings must be individually pressed in or otherwise introduced.
Ferner sind Verfahren bekannt, bei denen zur weiteren Vereinfachung der isolierenden Auskleidung die Wandungen der Wicklungsräume durch Ausspritzen od. dgl. mit geeigneten Isolierstoffen überzogen werden. Stattdessen werden auch die Wicklungsträger in Kunstharzlacke oder erwärmte thermoplastische Mässen eingetaucht, so daß der gesamte Wicklungsträger mit einer Isolierschicht überzogen wird. Die letztgenannten Verfahren haben den Nachteil, daß gerade an den Stellen, an denen die Isolierschicht besonderen Beanspruchungen ausgesetzt ist, nämlich an den Kanten der Wicklungsräume, nur eine sehr dünne Isolierschicht verbleibt, weil dort der Isolierstoff abzulaufen versucht. Um diesen Nachteil zu vermeiden; ist es an sich gebräuchlich, an den -Kanten, um die die Wicklungen gelegt werden müssen, eine besondere Verstärkung der Isolation vorzusehen. Zu diesem Zweck werden zusätzliche, den jeweiligen Formen angepaßte Isolierteile aus Pappe; Papier oder Preßstoff um die Kanten gelegt. Diese nachträglich aufgebrachten Isolierteile haben aber keine feste Verbindung mit dem Wicklungskörper und können sich deshalb leicht verschieben; außerdem isolieren sie nur im Rahmen der ihnen eigenen, einfachen Isolierfähigkeit.Furthermore, methods are known in which for further simplification the insulating lining the walls of the winding spaces by injection molding or the like. Be covered with suitable insulating materials. Instead, too the winding carriers are immersed in synthetic resin lacquer or heated thermoplastic dimensions, so that the entire winding support is covered with an insulating layer. the The latter method have the disadvantage that precisely at the points where the insulating layer is exposed to particular stresses, namely at the edges of the winding spaces, only a very thin insulating layer remains because the Tried to expire the insulating material. To avoid this disadvantage; it is in itself common, on the edges around which the windings must be placed, a special one Provide reinforcement of the insulation. For this purpose additional, the respective Molded insulating parts made of cardboard; Paper or pressed material wrapped around the edges. However, these subsequently applied insulating parts do not have a permanent connection with the winding body and can therefore move easily; also isolate they only within the framework of their own simple ability to isolate.
Erfindungsgemäß werden diese .zusätzlichen Isolierteile vor dem Tauchen oder Spritzen aufgebracht, so daß sie mitgetaucht oder mitgespritzt werden und- so mit dem Wicklungsträger fest verbunden sind. Damit ergeben sich die besonderen Vorteile, daß sich die zusätzlichen Isolierteile nicht mehr verschieben können, der aufgebrachte Isolierstoff besser haftet sowie die Isolierfähigkeit des Papiers durch Einsaugen verbessert und somit auch an den Kanten eine einwandfreie Isolierung gewährleistet wird.According to the invention, these additional insulating parts are applied before diving or syringes applied so that they are also immersed or injected and- are firmly connected to the winding support. This results in the special ones Advantages that the additional insulating parts can no longer move, the applied insulating material adheres better as well as the insulating properties of the paper improved by suction and therefore perfect insulation at the edges as well is guaranteed.
