Verfahren zur Beseitigung schädlicher Lufteinschlüsse bei der Herstellung von elektrischen Kondensatoren.Process for eliminating harmful air inclusions in the manufacture of electrical capacitors.
Bei elektrischen Kondensatoren, die in bekannter Weise z.B. durch Aufwickeln abwechselnd geschichteter Isolier-und Metallfolienbahnen hergestellt werden, ergibt sich die Schwierigkeit, Lufteihschlüsse in diesem Wickel zu vermeiden bezw. durch entsprechende Nachbehandlung unter OeI oder durch Tränkung im Vakuum zu beseitigen.In the case of electrical capacitors, which are used in a known manner, e.g. by winding up alternating layers of insulating and metal foil strips are produced, there is the difficulty of avoiding air closures BEZW in this winding. through appropriate post-treatment to be removed under oil or by soaking in a vacuum.
Derartige LufteinsohlUsse bewirken infolge der durch sie hervorgerufenen i'eldverzerrungen beim Betrieh des Kondensators und — bei Vorhandensein genügend hoher Spannung — auftretender I ο η i s i e rung an disen Stellen eleltrisehe Durchschlage des Dielektrikums und damit Zerstörung des Kondensators.As a result of the field distortions caused by them, such air insoles cause the condenser to be operated and - if it is present Sufficiently high voltage - occurring I ο η i s i e tion at these points electrical breakdown of the dielectric and thus Destruction of the capacitor.
Das neue Verfahren vermeidet eine Vakuurabehandlung, indem der fertig geschichtete oder gewickelte Kondensator in geeigneter Weise getränkt wird, während er sich in einem ültraschallfeld einstellbarer Stärke befindet. Unter der Einwirkung der Ultrasohallschwingungen werden alle lufteinschlüsse "herausgeklopft" und eine restlose Durohtränkung erreicht.The new process avoids vacuum treatment by soaking the finished layered or wound capacitor in a suitable manner while it is in an ultrasonic field of adjustable strength. Under the influence of ultrasound vibrations all air inclusions are "knocked out" and a complete Durohm impregnation is achieved.
