Description

Verfahren zur Beseitigung schädlicher Lufteinschlüsse bei der Herstellung von elektrischen Kondensatoren Bei elektrischen Kondensatoren, die in bekannter Weise, z. B. durch Aufwickeln abwechselnd geschichteter Isolier- und Metallfolienbahnen hergestellt werden, ergibt sich die Schwierigkeit, Lufteinschlüsse in diesem Wickel zu vermeiden bzw. durch entsprechende Nachbehandlung unter 01 oder durch Tränkung im Vakuum zu beseitigen.Method for eliminating harmful air inclusions in the production of electrical capacitors. B. are produced by winding alternately layered insulating and metal foil webs, there is the difficulty of avoiding air inclusions in this winding or eliminating it by appropriate post-treatment under 01 or by soaking in a vacuum.

Derartige Lufteinschlüsse bewirken infolge der durch sie hervorgerufenen Feldverzerrungen beim Betrieb des Kondensators und, bei Vorhandensein ,genügend hoher Spannung, auftretender lonisierung an diesen Stellen elektrische Durchschläge des Dielektrikums und damit Zerstörung des Kondensators.Such air inclusions are caused by them Field distortions when operating the capacitor and, if present, sufficient high voltage, ionization occurring at these points, electrical breakdowns of the dielectric and thus destruction of the capacitor.

Das neue Verfahren vermeidet eine Vakuumbehandlung, indem der fertig geschichtete oder gewickelte Kondensator in geeigneter Weise getränkt wird, während er sich in einem Ultraschallfeld einstellbarer Stärke befindet. Unter der Einwirkung der Ultraschallschwingungen werden alle Lufteinschlüsse herausgeklopft und eine restlose Durchtränkung erreicht.The new process avoids vacuum treatment by the done layered or wound capacitor is suitably soaked while it is located in an ultrasonic field of adjustable strength. Under the influence of the ultrasonic vibrations, all air pockets are knocked out and one complete saturation achieved.
