Description
Wicklung, insbesondere für hohen Stoßbelastungen ausgesetzte elektrische Maschinen und Apparate, die aus einem umsponnenen, mit Silikonlack imprägnierten Draht hergestellt ist Die Wicklungen elektrischer Maschinen und Apparate, wie z. B. für Transformatoren und Motoren, bestehen im allgemeinen aus einem umsponnenen, mit einem Isolierlack imprägnierten Draht. Nach Herstellen der Wicklung bzw. beim Herstellen der Wicklung wird die Wicklung mit einem Isolierlack getränkt, um einen einigermaßen festen Körper zu erhalten. Die meisten bekannten Verfahren verwenden für das Imprägnieren des Drahtes und das Tränken der Wicklung organische Lacke, die aber nur in bestimmten Grenzen wärmebeständig sind. Um eine größere Wärmebeständigkeit der Isolierung wie auch des Tränklackes zu erhalten, hat man daher Silikonlacke für die Tränkung und Imprägnierung verwendet. Silikonlacke sind aber in der Herstellung zu teuer, so daß sich diese Lacke bisher nicht durchsetzen konnten. Um jedoch trotzdem eine höhere Wärmebeständigkeit erreichen zu können, hat man daher einen Kompromiß vorgeschlagen, nach dem man die Wicklung aus einem mit Silikonlack imprägnierten Draht herstellt und dann in einem organischen Tränklack z. B. auf der Basis von präparierten Resolharzen in Verbindung mit modifizierten Alkylharzen tränkt.Winding, especially for electrical equipment exposed to high shock loads Machines and devices made from a wrapped, impregnated with silicone varnish Wire is made The windings of electrical machines and apparatus, such as B. for transformers and motors, generally consist of a braided, wire impregnated with an insulating varnish. After making the winding or when To produce the winding, the winding is impregnated with an insulating varnish to create a to get a reasonably solid body. Use most known procedures for the impregnation of the wire and the impregnation of the winding, organic varnishes, but they are only heat-resistant within certain limits. To have greater heat resistance To preserve the insulation as well as the impregnating varnish, one therefore has silicone varnishes used for impregnation and impregnation. However, silicone varnishes are in the process of being manufactured too expensive, so that these paints have not yet been able to establish themselves. However, to anyway There is therefore a compromise to be able to achieve higher heat resistance suggested after which one impregnated the winding from a with silicone varnish Wire produces and then in an organic impregnation varnish z. B. on the basis of prepared resole resins in connection with modified alkyl resins.
Wie jede Kompromißlösung hat auch diese Methode zu keinem befriedigenden Erfolg geführt. Die Erfindung bezieht sich auf eine Wicklung, insbesondere für hohen Strombelastungen ausgesetzte elektrische Maschinen und Apparate, die aus einem umsponnenen, mit Silikonlack imprägnierten Draht hergestellt ist und bei der der zur Wicklung verformte Draht einer weiteren Lackbehandlung durch Tränken unterworfen wird, Der Erfindung liegt ebenfalls die Aufgabe zugrunde, die Wicklung mit einem Lack zu tränken., dessen Temperaturfestigkeit der des Imprägnierlackes ungefähr angepaßt ist, jedoch die Nachteile der -o. a. bekannten Kompromiß.lösu-ng zu vermeiden. Erfindungsgemäß wird dies bei den genannten Wicklungen dadurch. erreicht, daß der für das Tränken des zur Wicklung verformten Drahtes dienende Lack aus einem monomeren aromatischen Orthokieselsäureester und einem organischen Lack besteht.Like any compromise solution, this method does not lead to any satisfactory results Success led. The invention relates to a winding, especially for high Electrical machines and apparatus exposed to current loads that consist of a braided, made of wire impregnated with silicone varnish and used for winding deformed wire is subjected to a further lacquer treatment by impregnation, The The invention is also based on the object of impregnating the winding with a lacquer., the temperature resistance of which is approximately matched to that of the impregnation varnish, however the disadvantages of -o. a. known compromise solution. According to the invention this is the case with the windings mentioned. get that for soaking The enamel used for the winding of the wire is made from a monomeric aromatic Orthosilicic acid ester and an organic lacquer.
Es ist an sich bekannt,. polymerisierte Orthokieselsäureester u. a. auch in Vermischung mit organischen Lacken zum Imprägnieren und isolierenden Überziehen elektrischer Artikel zu verwenden. Lacke, die unter Verwendung polymerisierter Orthoki-eselsäureester hergestellt sind, neigen aber im Gegensatz zu Lacken, die aus monomeren, also nicht polymerisierten Orthokieselsäureestern hergestellt sind, zu starker Versprödung und sind daher als Tränkmittel für elektrische Wicklungsisolationen völlig ungeeignet. Im Gegensatz dazu kann man mit einem Lack, der gemäß der Erfindung aus einem monomeren aromatischen Orthokieselsäureester und einem organischen Lack besteht, eine genau so gute Verk'lebung und Verbackeng der silikonisolierten Drähte wie mit organischen Tränklacken erreichen und hat aber als großen Vorteil die höhere thermische Stabilität.It is known per se. polymerized orthosilicic acid esters, inter alia. also mixed with organic lacquers for impregnation and insulating coating electrical article to use. Varnishes made using polymerized Orthoki-eselsäureester are made, but in contrast to lacquers that are made from monomeric, so do not polymerized orthosilicic acid esters lead to severe embrittlement and are therefore completely unsuitable as impregnating agents for electrical winding insulation. In contrast, you can with a paint, which according to the invention from a monomeric aromatic orthosilicic acid ester and an organic varnish, one exactly the silicon-insulated wires are as well bonded and bonded as with organic ones Impregnating varnishes achieve and have the great advantage of higher thermal stability.
