Description

Verfahren zur Herstellung der isolierenden, aus Papier bestehenden Auskleidung von Ölbehältern für elektrische Apparatef insbesondere Ölschalter Es ist in ölgefüllten elektrischen Apparaten, insbesondere Ölschaltern, üblich, den Ölbehälter mit einer dielektrischen Schicht, z. B. Holz oder anderem geeigneten Material, auszukleiden, um auf diese Weise einem Spannungsübergang zwischen den an Spannung liegenden Teilen und der Behälterwand vorzubeugen, der zufolge der Brücken, welche sich aus den Verunreinigungen des Öles in der Gegend großer elektrischer Feldstärke bilden, oder der Verdrängung des Öles durch das beim Abschaltvorgang sich entwickelnde Gas stattfinden könnte. Holz eignet sich nach neueren Erfahrungen für diese Zwecke weniger gut, und man ist daher vielfach zur Verwendung von Hartpapier übergegangen. Bei KesselnvongrößerenAbmessungen, insbesondere großem Durchmesser, benötigt man dann sehr große Wickeldorne, und da die Fertigung dann allgemein gewisse Erschwernisse bereitet, insbesondere auch bei ÖlbehälternbesondererFormgebung, werden die Gestehungskosten solcher Auskleidungen sehr hoch.Process for the production of the insulating, made of paper Lining of oil containers for electrical apparatus, in particular oil switches is common in oil-filled electrical apparatus, especially oil switches, the Oil container with a dielectric layer, e.g. B. wood or other suitable Material, lining, in order to create a tension transition between the to prevent parts that are under tension and the container wall, which, as a result of the bridges, which result from the impurities of the oil in the area of great electrical Form field strength, or the displacement of the oil by the during the shutdown process evolving gas could take place. According to recent experience, wood is suitable less good for these purposes, and one is therefore often in favor of using hard paper passed over. For boilers of larger dimensions, especially large diameters, you then need very large mandrels, and since the production then generally certain Difficulties are created, especially in the case of oil containers with a special shape the prime cost of such linings is very high.

Zur Vermeidung dieser Schwierigkeiten wird nach der Erfindung die Auskleidung des Ölbehälters in der Weise vorgeschlagen, daß auf die innere Behälterwand nach und nach eine der erwünschten Auskleidung entsprechende Anzahl Papierlagen aufgebracht wird, von denen die erste durch ein geeignetes Bindemittel unmittelbar mit der Behälterwand und die nachfolgenden in gleicher Weise untereinander verbunden werden. Man kann hierzu einzelne einander überlappende Streifen oder eine einheitliche Papierbahnwiebei der Herstellung vonHartpapierzylindern benutzen. Die Fertigung des Isolierkörpers erfolgt dann in analoger Weise, nur daß er nicht von innen nach außen hergestellt wird, wie es beim Aufwickeln auf einen Dorn der Fall ist, sondern von außen nach innen, wobei der Behälter als Außenkaliber benutzt wird und somit jeder Dorn entbehrlich wird. .To avoid these difficulties, according to the invention Lining the oil container in such a way proposed that on the inner container wall gradually a number of paper layers corresponding to the desired lining is applied, the first of which by a suitable binder directly connected to the container wall and the following in the same way will. You can do this with individual overlapping strips or a uniform one Use paper web as in the manufacture of hard paper cylinders. Manufacturing of the insulating body is then carried out in an analogous manner, only that it does not turn from the inside is made outside, as is the case when winding on a mandrel, but from the outside to the inside, the container being used as the outer caliber and thus every thorn becomes dispensable. .
