Description

Isolieröl für elektrotechnische Zwecke, insbesondere für Transformatoren und Kondensatoren Bekannt ist es, Hexachlorbutadien (C,C16) als Isolieröl zu benutzen. Die Erfahrung hat gezeigt, daß dieses Öl für elektrische Zwecke wegen seiner geringen chemischen Stabilität und seiner niedrigen Dielektrizitätskonstante von etwa 2,4 nur beschränkt verwendbar und für Kondensatoren geradezu unbrauchbar ist.Insulating oil for electrotechnical purposes, especially for transformers and capacitors It is known to use hexachlorobutadiene (C, C16) as an insulating oil. Experience has shown that this oil can only be used to a limited extent for electrical purposes because of its low chemical stability and its low dielectric constant of about 2.4 and is virtually unusable for capacitors.

Aufgabe der Erfindung ist es, das genannte Isolieröl zu verbessern. Gemäß der Erfindung erreicht man dies dadurch, daß bei dem C4 C16-Molekül mindestens i Chloratom durch Halogenatome, beispielsweise Fluor, Brom oder Jod, ersetzt wird. Durch diese Chloratomersetzung ergeben sich Verbindungen, wie C4 C15 F (Pentachlormonofluorbutadien) oder C,C14Fz (Tetrachlordufluorbutadien) bzw., wenn an Stelle von Fluor Brom oder Jod tritt, Verbindungen, wie C4 C15 Br oder C4CII J. Es können auch drei verschiedene Halogene gleichzeitig angelagert werden, wie z. B. C4 C14F Br oder C4 C14 F J usw. Zweckmäßig ersetzt man nur i oder 2 Chloratome des Hexachlorbutadiens in unsymmetrischer Anordnung durch ein anderes Halogen. Gleichgültig ist es dabei, an welcher Stelle (a, ß, y-Stellung usw.) die Halogensubstitution eintritt. Dies ist in der Hauptsache durch die jeweilig gewählte Art des Anlagerungsverfahrens bestimmt. Selbstverständlich sind auch die isomeren Gemische des erfindungsgemäßen Isolieröls gleichermaßen für den vorgesehenen Zweck benutzbar.The object of the invention is to improve said insulating oil. According to the invention, this is achieved in that in the case of the C4 C16 molecule at least i the chlorine atom is replaced by halogen atoms, for example fluorine, bromine or iodine. This chlorine atom decomposition results in compounds such as C4 C15 F (pentachloromonofluorobutadiene) or C, C14Fz (tetrachlorodufluorobutadiene) or, if instead of fluorine bromine or Iodine occurs compounds like C4 C15 Br or C4CII J. There can also be three different ones Halogens are added at the same time, such as. B. C4 C14F Br or C4 C14 F J etc. It is expedient to replace only 1 or 2 chlorine atoms of the hexachlorobutadiene in unsymmetrical ones Arrangement by a different halogen. It does not matter at which point (a, ß, y-position etc.) the halogen substitution occurs. This is the main thing determined by the type of attachment process chosen. Of course are also the isomeric mixtures of the insulating oil according to the invention equally for usable for the intended purpose.

Der Vorteil des erfindungsgemäßen Isolieröls liegt einerseits in seiner gegenüber dem Hexachlorbutadien wesentlich erhöhten chemischen Stabilität und seiner günstigeren elektrischen Eigenschaften. Besonders günstig erweist sich die durch die unsymmetrische Anlagerung von Halogenatomen erzielte höhere Dielektrizitätskonstante des Öls. Infolge dieser Eigenschaft ist das neue Isolieröl auch für den Kondensatorbau brauchbar.The advantage of the insulating oil according to the invention is on the one hand in its compared to the hexachlorobutadiene significantly increased chemical stability and its more favorable electrical properties. That proves to be particularly favorable through the asymmetrical addition of halogen atoms achieved a higher dielectric constant of the oil. As a result of this property, the new insulating oil is also suitable for condenser construction useful.

Das erfindungsgemäße Isolieröl läßt sich mit Vorteil auch in Form von Dämpfen verwenden, insbesondere dann, wenn solche Dämpfe vor allem gasförmigen Isolierstoffen, beispielsweise Luft, Stickstoff, Sauerstoff, Kohlensäure usw., beigemischt werden. Die durch die Beimengung erzielte höhere elektrische Festigkeit des Isoliergases ist besonders auffallend.The insulating oil according to the invention can also advantageously be in the form use of vapors, especially when such vapors are mostly gaseous Insulating materials, such as air, nitrogen, oxygen, carbonic acid, etc., mixed in will. The higher electrical strength of the insulating gas achieved through the admixture is particularly noticeable.
