Description

Unter Öl befindlicher elektrischer Apparat Das Patent 482 179 behandelt ein Verfahren zur Verhütung der Bildung von explosiven Gasgemischen in unter Öl gebetteten, elektrischen Apparaten, welches dadurch gekennzeichnet ist, daß eine stetige Be- und Entlüftung in dem über dem Ölspiegel befindlichen Raum hervorgerufen wird. Die bei diesem Verfahren vorgesehene stetige Luftströmung verhütet nun nicht nur die Bildung von explosiven Gasgemischen, die durch die bei Schaltungen und Störungen entstehenden Zersetzungsgase des Öles in Verbindung mit dem Sauerstoff der Luft sich entwickeln können, sondern kann auch dazu benutzt werden, den sich neben den explosiven Gasgemischen bildenden Ruß aus dem elektrischen Apparat zu entfernen. Die Entfernung des Rußes ist deswegen von Wichtigkeit, weil er das Öl verunreinigt und durch Vermischung mit Luft einen Überschlag zwischen den unter Spannung stehenden Teilen, die sich über Öl, im Apparat oder außerhalb des Apparates befinden, begünstigt.Oiled electrical apparatus. Patent 482,179 dealt with a method of preventing the formation of explosive gas mixtures in under oil bedded electrical apparatus, which is characterized in that a constant ventilation caused in the space above the oil level will. The steady flow of air provided in this process does not prevent it only the formation of explosive gas mixtures caused by switching and malfunctions resulting decomposition gases of the oil in connection with the oxygen in the air can develop, but can also be used to expand alongside the to remove soot that forms explosive gas mixtures from electrical equipment. Soot removal is important because it contaminates the oil and by mixing with air, a flashover between the energized ones Parts that are above the oil, in or outside the apparatus, are favored.

Der Ruß kann nun von dem Luftstrom direkt ins Freie geführt oder gemäß der vorliegenden Erfindung von einem Filter aus Watte, Spänen, Glaswolle, Asbest o. dgl. aufgenommen werden, das sich an jeder geong neten Stelle des elektrischen Apparates einbauen läßt.The soot can now be led directly into the open air by the air stream or according to of the present invention of a filter made of cotton wool, chips, glass wool, asbestos o. The like. Be included, which is located at each geong Neten point of the electrical Can be installed in the apparatus.
