Description

Elektrischer Kondensator Zur Herstellung von Kondensatoren wird hauptsächlich paraffiniertes Papier verwendet. Glimmerkondensatoren haben wegen ihres hohen Preises nur ein beschränktes Anwendungsgebiet, und zwar dort, wo ein möglichst verlustfreies Arbeiten erforderlich ist. Papierkondensatoren haben nur eine geringe Durchschlagsfestigkeit und hohe dielektrische Verluste. Sie sind leicht einer Schädigung durch Eindringen von Feuchtigkeit in die Papierfaser ausgesetzt. Nachteilig ist auch der niedrige Erweichungspunkt des paraffinierten Papiers. Diese Nachteile können dadurch behoben werden, daß man erfindungsgemäß als Dielektrikum das auch als Isolierstoff bekannte polymerisierte Styrol verwendet. Polystyrol hat eine außergewöhnlich hohe Durchschlagsfestigkeit und nur niedrige dielektrische Verluste. Es ist gegen eindringende Feuchtigkeit sehr beständig. Kondensatoren, deren Dielektrikum aus Polystyrol besteht, sind bis auf die Wärmebeständigkeit den teueren Glimmerkondensatoren gleichwertig. Dabei ist die Herstellung derartiger Kondensatoren sehr einfach. Man kann. das Dielektrikum fest mit der Metallfolie in Form eines gut haftenden Überzugs verbinden. Überzieht man die Metallfolien beiderseitig, so hat man außerdem den Vorteil, daß sich zwischen je zwei Metallblättchen eine zweifache Schicht des Dielektrikums befindet. Um die Geschmeidigkeit der Polystyrolüberzüge zu erhöhen, kann es zweckmäßig sein, ihnen geeignete Weichmachungsmittel, wie hochsiedende Ester, Ketone, Äthylacetanilid o. dgl., zuzusetzen. Auch ist es möglich, der Lösung von polymerem Styrol Kautschuk beizumengen, der sowohl eine weichmachende als auch eine gut isolierende Wirkung hat.Electrical Capacitor The main production of capacitors is used paraffin paper. Mica capacitors have because of their high price only a limited area of application, namely where it is as loss-free as possible Work is required. Paper capacitors only have a low dielectric strength and high dielectric losses. They are easily damaged by penetration exposed to moisture in the paper fiber. The low one is also disadvantageous Softening point of the paraffinized paper. These disadvantages can thereby be remedied be that according to the invention, the dielectric is also known as an insulating material polymerized styrene is used. Polystyrene has an exceptionally high dielectric strength and only low dielectric losses. It is against penetrating moisture very consistent. Capacitors with a polystyrene dielectric are up to equivalent to expensive mica capacitors in terms of heat resistance. Included the manufacture of such capacitors is very simple. One can. the dielectric firmly bond to the metal foil in the form of a well-adhering coating. Covers if you have the metal foils on both sides, you also have the advantage that between every two metal flakes a double layer of the dielectric is located. To the To increase the pliability of the polystyrene coatings, it may be useful to use them suitable plasticizers, such as high-boiling esters, ketones, ethylacetanilide, etc. Like. To add. It is also possible to use the solution of polymeric styrene rubber add, which has both a softening and a good insulating effect Has.
