Halogenierte aromatische Verbindungen und insbesondere chlorierte Diphenylverbindungen sind bisher als Dielektrika für elektrische Geräte, z. B. Transformatoren und Kondensatoren für Kühlzwecke und als Isolatoren, vielfach verwendet worden. Diese Verbindungen haben den Vorteil vor vielen nichtleitenden Mineralölen, daß sie nicht entflammen. Eine Schwierigkeit, die bei der Verwendung von chlorierten aromatischen Verbindungen für diese Zwecke auftritt, ist, daß die elektrischen Entladungen im Gerät oder eine chemische Hydrolyse die chlorierte Verbindung zersetzen können, so daß sich vorzugsweise Chlorwasserstoff bildet, der die Eigenschaften des Dielektrikums nachteilig beeinflußt und zur Korrosion der Metallteile des Gerätes und zur Abschwächung anderer isolierender Teile führt. Um diese Schwierigkeit zu überwinden, wurden der dielektrischen Flüssigkeit sogenannte Getter zugesetzt, um die Wirkung des Chlorwasserstoffes oder anderer Zersetzungsprodukte zu neutralisieren oder aufzuheben. Die bisher verwendeten Getter besaßen indessen einige Nachteile, z. B. reagierten sie zu langsam auf die Zersetzungsprodukte oder waren besonders kostspielig oder beeinflußten die Eigenschaften der dielektrischen Flüssigkeit in unerwünschter Weise.Halogenated aromatic compounds and in particular chlorinated diphenyl compounds have been used as dielectrics for electrical equipment, e.g. B. Transformers and capacitors for cooling purposes and as insulators, have been widely used. These connections have the advantage over many non-conductive mineral oils that they do not ignite. A problem, which occurs when using chlorinated aromatic compounds for these purposes is, that the electrical discharges in the device or a chemical hydrolysis decompose the chlorinated compound can, so that hydrogen chloride is preferably formed, which has the properties of the dielectric adversely affects and corrosion of the metal parts of the device and the weakening of others insulating parts. In order to overcome this difficulty, dielectric liquids were used So-called getter is added to the effect of the hydrogen chloride or other decomposition products to neutralize or cancel. The getters used up to now had, however, some disadvantages, z. B. did they react too slowly to the decomposition products or were particularly expensive or undesirably affected the properties of the dielectric fluid.
Es wurde nun gefunden, daß Isolieröle auf der Basis von chlorierten Aromaten diese Nachteile nicht besitzen, wenn sie 0,001 bis 10 Gewichtsprozent 1-Epoxyäthyl-3,4-epoxycyclohexan enthalten. 1-Epoxyäthyl-3,4-epoxycyclohexan besitzt die FormelIt has now been found that insulating oils based on chlorinated aromatics do not have these disadvantages, if they are 0.001 to 10 percent by weight of 1-epoxyethyl-3,4-epoxycyclohexane contain. 1-epoxyethyl-3,4-epoxycyclohexane owns the formula

Vergleiche tiber die Lebensdauer wurden an zwei Gruppen von je sechs Kondensatoren durchgeführt, wobei die eine Gruppe ein flüssiges Dielektrikum der Zusammensetzung von Beispiel 2 enthielt, während die andere, /um Vergleich dienende Gruppe das gleiche Dielektrikum ohne einen Epoxydstabilisalor enthielt. Die Kondensatoren, die für 3,7 μ und eine Wechselspannung von 330 V ausgelegt waren, wurden bei 85 C und einer Wechselspannung von 880 V auf ihre Lebensdauer geprüft. Bei dieser Prüfung stellte man fest, dali sämtliche Kondensatoren der Vergleichsserie vor Ablauf von 3000 Stunden versagten und eine durchschnittliche Lebensdauer von 1277 Stunden besaßen, während die erfindungsgemäß stabilisierten Kondensatoren bei den Versuchsbedmgungen noch nach 13000 Stunden befriedigend arbeiteten.Life comparisons were made on two Groups of six capacitors each carried out, one group being a liquid dielectric of the Composition of Example 2, while the other / comparative group contained the the same dielectric without an epoxy stabilizer. The capacitors that for 3.7 μ and a AC voltage of 330 V were designed at 85 C and an AC voltage of 880 V checked their service life. During this test it was found that all capacitors in the comparison series failed before 3000 hours had elapsed and one had an average life of 1277 hours, while those stabilized according to the invention Capacitors still worked satisfactorily after 13,000 hours under the test conditions.
Es ist also erwiesen, dali die Criindung eine erhebliche Verbesserung der Lebensdauer von Kondensatoren bewirkt.It has therefore been proven that the formation of the disease is considerable Improving the life of capacitors causes.
Der beschleunigte Enlzug oder \bbau der Zersetzungsprodukte, der mit Hilfe der Erfindung bewirkt wird, führt nicht nur zu einer weit geringeren Korrosion der Metallteile der Gerate, sondern auch zu einer vorteilhaften Verringerung der chemischen Wirkung des gelösten Chlorwasserstoffes auf Papier oder andere /ellulosehaltige Stoffe innerhalb des Gerätes.The accelerated extraction or construction of the decomposition products, which is brought about with the aid of the invention, not only leads to far less corrosion of the metal parts of the devices, but also to an advantageous reduction in the chemical effect of the dissolved hydrogen chloride on paper or other / ellulosic substances within of the device.
