Description

Verfahren zur Herstellung elektrischer Kondensatoren mit einem Abstandshalter zwischen Kondensatorwickel und metallischem Gehäuse Die Erfindung betrifft ein Verfahren zur Herstellung elektrischer Kondensatoren mit einem Abstandshalter aus einem körnigen oder faserigen Material zwischen Kondensatorwickel und metallischem Gehäuse.Method of manufacturing electrical capacitors with a spacer between capacitor winding and metallic housing The invention relates to a method for making electrical capacitors with a spacer from a granular or fibrous material between the capacitor winding and the metallic housing.

Bei einem bekannten Verfahren wird die das Gehäuse bildende Folie mit einer Mischung aus Gießharz und Füllstoff beschichtet und das Ganze im flüssigen Zustand um den Kondensatorwickel herumgewickelt. Dabei muß die aufgetragene Schicht ziemlich dick sein, damit an den Stirnseiten überschüssiges Material herausquellen kann. Es versteht sich, daß die Verarbeitung einer derart vorbehandelten und beschichteten Aluminiumfolie schwierig sein wird, zumal es sich immer um kurze Folienabschnitte handelt, die um die einzelnen Kondensatorwickel herumgewickelt werden müssen. Eine maschinelle Verrichtung dieses Arbeitsganges ist mit Rücksicht auf den flüssigen Zustand des Gießharzes kaum durchführbar.In a known method, the film forming the housing is used coated with a mixture of casting resin and filler and the whole thing in the liquid State wrapped around the capacitor winding. The applied layer must be be quite thick so that excess material oozes out on the front sides can. It goes without saying that the processing of such a pretreated and coated Aluminum foil will be difficult, especially since it will always be short sections of foil acts that have to be wound around the individual capacitor windings. One Mechanical performance of this operation is with regard to the liquid The condition of the cast resin is hardly feasible.

Das Verfahren gemäß der Erfindung läßt sich wesentlich einfacher durchführen und besser beherrschen als das erwähnte bekannte Verfahren. Es besteht darin, daß zunächst auf die Oberfläche des Kondensatorwickels oder auf die Innenfläche des metallischen Gehäuses eine Haftschicht aufgebracht wird, worauf ein Beschichten dieser Haftschicht mit einem isolierenden, körnigen oder faserigen Material erfolgt, daß dann der Kondensatorwickel in das Gehäuse eingesetzt wird und schließlich die Hohlräume zwischen den Körnern oder Fasern des isolierenden Materials oberhalb der Haftschicht mit Vergußwerkstoff ausgefüllt werden.The method according to the invention can be carried out much more easily and master it better than the aforementioned known method. It is that first on the surface of the capacitor winding or on the inner surface of the metallic housing an adhesive layer is applied, followed by a coating this adhesive layer is made with an insulating, granular or fibrous material, that then the capacitor winding is inserted into the housing and finally the Voids between the grains or fibers of the insulating material above the Adhesive layer to be filled with potting material.

Das körnige oder faserige Material besteht vorwiegend aus anorganischen Stoffen, wie beispielsweise Quarz, Speckstein, Asbest. Durch entsprechende Wahl der Körnigkeit läßt sich in bekannter Weise ein bestimmter Abstand sehr einfach einstellen.The granular or fibrous material consists mainly of inorganic Substances such as quartz, soapstone, asbestos. By appropriate choice The granularity can be easily adjusted to a certain distance in a known manner to adjust.
