Description

Transformatoren- und Schalteröle. Es wurde gefunden, daß sich flüssige Triarylphosphate, z. B. Gemische der isomeren Trikresylphosphate oder die gemischten Ester, wie sie nach den Patentschriften 348628 und 348629 erhalten werden können, besonders vorteilhaft- als Transformatoren- und Schalteröle in der Elektrotechnik verwenden lassen. Die Vorteile ihrer Verwendung gegenüber den bisher üblichen Mineralölen bestehen außer der großen Isolierfähigkeit vor allem in ihrer chemischen Indifferenz und Reinheit, dem Mangel jeglichen Teer- und Schwefelgehalts, in dem hohen Flamm- und Brennpunkt, dem niedrigen Gefrierpunkt, der Unvermischbarkeit mit Mineralölen und Wasser und in dem hohen spezifischen Gewicht, das größer ist als das des Wassers. Hierdurch wird erreicht, daß das sich bildende Kondenswasser oder beim Überfluten von Transformatoren in Schächten usw. eindringendes Wasser nicht in den Wicklungsraum. des Transformators eindringen kann, was bekanntlich häufig die Zerstörung der Wicklung hewirkt.Transformer and switch oils. It has been found that liquid triaryl phosphates, e.g. B. Mixtures of the isomeric tricresyl phosphates or the mixed esters, as can be obtained according to patents 348628 and 348629, can be used particularly advantageously as transformer and switch oils in electrical engineering. The advantages of their use compared to the mineral oils commonly used up to now consist of their chemical indifference and purity, the lack of any tar and sulfur content, the high flash point and fire point, the low freezing point, immiscibility with mineral oils and water and, in addition to their great insulating properties in the high specific weight, which is greater than that of water. This ensures that the condensation water that forms or water that does not penetrate into the winding space when transformers are flooded in shafts, etc. of the transformer can penetrate, which, as is well known, often causes the destruction of the winding.
