Description

Bei den bekannten Verfahren wird z. B. Aluminiumfolie in wäßrigem Elektrolyt vorformiert, darauf die formierte Folie als Anode i (siehe Abb.) mit Abstandhalterpapier 2 und einer Aluminiumkathode 3 zu einem Wickelkondensator 4 gewickelt.. Das Abstandhalterpapier 2 wird nach einem der bekannten Verfahren mit Nachformierungselektrolyt imprägniert und danach der Kondensator einer zweiten Formierung, der sogenannten Nachformierung, unterzogen.In the known method, for. B. aluminum foil in aqueous Preformed electrolyte, then the formed foil as anode i (see fig.) Spacer paper 2 and an aluminum cathode 3 to form a wound capacitor 4 wound .. The spacer paper 2 is according to one of the known methods with Impregnated reforming electrolyte and then the capacitor of a second formation, the so-called reforming, subjected.

Die Erfindung sucht nun zur Verbilligung, Vereinfachung und Verbesserung mit einer einzigen Formierung auszukommen. Dies scheiterte bisher daran, daß der fertig imprägnierte Wickel beim Formieren zu heiß wurde, weil zuviel Störionen vorhanden waren, die Wärmeabfuhr ungenügend war und der Elektrolyt im Wickel zu schnell verbraucht wurde.The invention is now looking for cheaper, simplification and improvement get by with a single formation. This has failed so far because the The finished impregnated winding became too hot during forming because there were too many interfering ions were, the heat dissipation was insufficient and the electrolyte in the coil used up too quickly became.

Diese Mißstände vermeidet die Erfindung dadurch, daß extreme Reinheit aller Stoffe gewahrt wird und daß der Elektrolyt während der Formierung durch den Wickel hindurchströmt. Der Durchfluß des Elektrolyts 5 durch den Wickel 4 wird z. B. in bekannter Weise durch Zentrifugieren oder durch Pumpe bewirkt, wobei der Wickel abdichtend in eine konische Hülse 6 im Mantel der Zentrifugiertrommel oder im Zwischenboden eines Druck-Saugkessels 7 eingesetzt wird.The invention avoids these drawbacks by using extreme purity of all substances is preserved and that the electrolyte during the formation by the Winding flows through it. The flow of the electrolyte 5 through the coil 4 is z. B. effected in a known manner by centrifugation or by pump, the winding sealing in a conical sleeve 6 in the casing of the centrifugation drum or in the intermediate floor a pressure-suction boiler 7 is used.

Ein weiterer Vorteil liegt noch darin, daß die Formierschicht durch Risse, wie sie bei der Wickelung entstehen können, nicht mehr beschädigt werden kann, weil die Wickelung vor der Formierung erfolgt.Another advantage is that the forming layer through Cracks, such as those that can arise during winding, can no longer be damaged can, because the winding takes place before the formation.

Für besondere Zwecke kann auch zunächst mit wäßrigem Elektrolyt im Durchlauf vorformiert, danach in beheizter Vakuumkammer getrocknet und dann mit Nachformierungselektrolyt im Durchlauf nachformiert werden.For special purposes, it can also be used initially with an aqueous electrolyte Preformed run, then dried in a heated vacuum chamber and then with Reforming electrolyte can be reformed in the process.

Die Erfindung eignet sich auch zu hochwertigster Imprägnierung, weil hier der Elektrolyt, im Gegensatz zu den meisten üblichen Imprägnierungsverfahren, nur in einer Richtung in den Wickel eindringt. Ein Eindringen von beiden Enden dem Innern zu wirkt sich deswegen oft ungünstig aus, weil die Imprägnierung dabei länger dauert.The invention is also suitable for the highest quality impregnation because here the electrolyte, in contrast to most common impregnation processes, only penetrates the coil in one direction. Penetration from both ends of that Because of this, too much of the inside has an unfavorable effect, because the impregnation takes longer take.
