Description
Isolierende Füllmasse für elektrische Maschinen und Apparate aus organischem Stoff ' und einem anorganischen Füllstoff Für die Isolierung der Wicklungen @eIektrischer Maschinen und Apparate, beispielsweise für den Ausguß der Luftzwischenräume im Gefäß von Spannungswandlern oder auch der Wicklungsräume elektrischer Maschinen sind Füllmassen aus Preß oder Kunstharz oder auch Asphalt oder .ähnlichen Stoffen bekannt. Es ist auch bereits bekannt, zum größeren Teile Quarzsand zuzusetzen, um auf diese Weise die Wärmeableitfähigkeit der Masse und damit die Belastbarkeit des elektrischen Teiles zu erhöhen.Insulating filling compound for electrical machines and apparatus made of organic material Substance 'and an inorganic filler for the insulation of the windings Machines and apparatus, for example for pouring out the air spaces in the vessel of voltage converters or the winding spaces of electrical machines are filling compounds known from pressed or synthetic resin or asphalt or similar materials. It is also already known to add quartz sand to larger parts in order to do this the heat dissipation ability of the mass and thus the resilience of the electrical To increase part.
Gemäß der Erfindung soll bei solchen Isoliermassen für elektrische Maschinen und Apparate Schwerspat als Füllstoff zugesetzt werden. Untersuchungen haben gezeigt, daß ein solcher Zusatz von Schwerspat, der eines der spezifisch schwersten Mineralien ist, eine Verbesserung der Wärmeableitfähigkeit des Isolierstoffes ergibt, die über das bisher bekannte Maß weit hinausgeht. Wie bei den Quarzsand enthaltenden Isoliexmassien kann auch der Anteil des Schwerspats, der etwa in Sand- oder Pulverform zugesetzt wird, am Gesamtgewicht größer sein als der der Masse, jedoch ist auch lein geringerer Anteil unter Umständen zweckmäßig.According to the invention, such insulating compounds for electrical Machines and apparatuses barite can be added as a filler. Investigations have shown that such an addition of barite, which is one of the specifically heaviest Minerals, results in an improvement in the heat dissipation properties of the insulating material, which goes far beyond the previously known level. As with the quartz sand containing Isoliexmassien can also be the proportion of barite, which is in sand or powder form is added, in terms of total weight is greater than that of the mass, but is also l a smaller proportion may be useful.
Eine Imprägnierungsmasse für Faserstoffumhüllungen elektrischer Leitungsdrähte, die aus einem Gemenge von Leinöl mit Eisenoxyd und Zinkoxyd oder mit Eisenoxyd und Schwefelzink besteht, dem Kohlepulver und Schwerspat als körpergebende und das Erhärten des Leinöles verzögernde Stoffe zugesetzt sind, ist bereits bekannt. Die Erfindung bezieht sich dagegen .auf eine Isoliermasse für den Ausguß der Luftzwischenräume zwischen den einzelnen Drähten von elektrischen Apparaten und Maschinen, die aus Asphalt, Kunstharz oder einem ,ähnlichen Stoff besteht und in der der Zusatz von Schwerspat zur Erhöhung der Wärmeleitfähigkeit dient. Dementsprechend wird bei der Masse nach der Erfindung Schwerspat in einem wesentlich höheren Prozentsatz zugesetzt als bei der bekannten Masse, in der nur das vorzeitige Erhärten des Leinöls verhindert werden soll, damit die Imprägniermasse heim Biegen des Drahtes nicht bricht.An impregnation compound for fiber sheaths for electrical conductors, that of a mixture of linseed oil with iron oxide and zinc oxide or with iron oxide and Zinc sulfur consists of coal powder and barite as body-giving and hardening of the linseed oil are added delaying substances, is already known. The invention on the other hand, refers to an insulating compound for the pouring out of the air spaces between the individual wires of electrical apparatus and machines that come from Asphalt, synthetic resin or a similar substance and in which the addition of Barite serves to increase the thermal conductivity. Accordingly, the Mass according to the invention, heavy spar added in a significantly higher percentage than with the known mass, in which only prevents the premature hardening of the linseed oil should be so that the impregnation compound does not break when the wire is bent.
