Ölschalter für hohe Spannungen. Patentiert im Deutschen Reiche vom 20. März 1925 ab.Oil switch for high voltages. Patented in the German Empire on March 20, 1925.

Bei elektrischen. Apparaten, für hohe Spannungen, die in einem Ölbad arbeiten, müssen die Abstände zwischen. Punkten verschiedenen Potentials ein Vielfaches der Abstände sein, die sich aus der elektrischen. Festigkeit des reinen Öles errechnen. Das kommt daher, weil im elektrischen Feldi die im Öl schwebenden Veranreinigungeitt sich zu Brücken zwischen den Spannung führenden Teilen zusammenschließen und. dadurch die Durchschlagsfestigkeit des Öles wesentlich verschlechtern. Bei Ölschaltern vereinen sich außerdem leicht die beim Ausschalten, entstehendem Gase zu einer großen zusammenhängendem Gasblase, die zwischen Punkten verschiedener Spannung, ζ. Β. den Sehaltkontakten und dem Kasten, das öl zu einem großen Teil verdrängt, was auch eine erhebliche Herabsetzung der Überschlagspannung zur Folge hat.With electrical. Apparatus for high voltages, who work in an oil bath, the distances between. Points different Potential to be a multiple of the distances resulting from the electrical. Strength of the calculate pure oil. This is because those floating in the oil in the electric fieldi Pollution forms bridges between connect the live parts together and. thereby the dielectric strength of the oil deteriorate significantly. In the case of oil switches, the when switching off, the gases produced form a large contiguous gas bubble that is between Points of different tension, ζ. Β. the hold contacts and the box, the oil displaced to a large extent, which also significantly reduces the flashover voltage has the consequence.

Nach der Erfindung werden beide Mängel wirkungsvoll dadurch bekämpft, daß man die Ölstreckß zwischen Punkten verschiedenen Po-According to the invention, both deficiencies are effectively combated by the fact that Oil stretch between points of different po-

Diese Platten verhindern einmal das Zustandekommen der erwähnten Brücke aus ÖlverunreJnigungen, und sodann zerteilen sie auch große Gasblasen, so daß die Ölgase in kleineren Blasen hochzusteigen gezwungen sind und durch diese Verteilung die gesamte Isolationsstrecfce weniger, verkürzen können. In der Zeichnung ist eintentials through interposed plates solid insulating material. These plates prevent the mentioned bridge of oil pollution, and then they also break up large gas bubbles, see above that the oil gases are forced to rise in smaller bubbles and by this distribution the entire isolation distance less, can shorten.
