Description

Elektrischer Kondensator für höhere Betriebstemperaturen Die fortgeschrittene Anwendungstechnik für Kondensatoren: verlang t immer mehr nach solchen Kondensatoren, die hohe Betriebstemperatunen, insbesondere über iod°' C aushalten> Für Temperaturen bis i oo ° C liegt bei Kondensatoren mit Papier als abstand haltendem Dielektrikum die Lösung der Audgabens.tel,lung lediglich darin, daß man ein Imprägniermittel verwendet, welches bei diesen Temperaturen die geforderten elektrischen: und mechanischen Eige nschaften beibehält. Bei Temperaturen über ioo'°@ C wird hingegen bei den Papierkondensatoren bereits die Temperaturgrenze überschritten, welche die Papierfaser auf die Dauer aushält, ohne sich mechanisch so zu verändern, daß die Betriebssicherheit des Kondensators nicht gefährdet wird. Man ist also nicht mehr in der Lage, die Forderung nach. Kondensatoren mit Betriebstemperaturen über ioo°' C unter Verwendung von Papier als Dielektrikum zu erfüllen.Electrical condenser for higher operating temperatures The advanced Application technology for capacitors: there is more and more demand for such capacitors, that can withstand high operating temperatures, in particular above iod ° C> For temperatures up to 100 ° C is for capacitors with paper as the spacing dielectric the only solution to the problem is to use an impregnating agent used, which at these temperatures the required electrical: and mechanical Maintains ownership. At temperatures above 100 ° @ C, however, the paper capacitors the temperature limit that the paper fiber has in the long run has already been exceeded withstands without changing mechanically in such a way that the operational reliability of the capacitor is not endangered. So you are no longer able to make the call. Capacitors with operating temperatures above 100 ° C using paper as the dielectric to meet.

Der Erfindung gemäß wird als, Dielektr!-kum ganz oder teilweise Trdacetat gewählt. Vorzugsweise wird das absta,ndhaltende Dielektrikum aus Triacetatfol:iegebildet. Dadurch ist es möglich, betriebssichere Kondensatoren auch für Temperaturen weit über f001 C, z. B. für r50° C, herzust°11en.According to the invention, the dielectric is wholly or partly triacetate chosen. The spacing dielectric is preferably made Triacetatfol: ie formed. This makes it possible to use reliable capacitors as well for temperatures well above f001 C, e.g. B. for r50 ° C, manufactured.

Die gelegentlich zur Verwendung für Kondensatoren angegebenen Acetatcellulosen er-«-iesen sich wegen ihrer Empfindlichkeit gegen Feuchtigkeit als ungeeignet und «-aren auch nicht so wärmebeständig wie das Triacetat.The acetate celluloses occasionally indicated for use in capacitors he - «- found themselves unsuitable and because of their sensitivity to moisture «-Are not as heat-resistant as triacetate.
