Description
Verfahren zur Herstellung einer gewickelten Kondensatordurchführung mit eingelegten metallischen Steuerbelägen Es ist bekannt, Kondensatordurchführungen mit Gießharz zu imprägnieren. Soll die Imprägnierung von hochwertiger Qualität sein, so muß die fertige Kondensatordurchführung evakuiert und der Imprägniervorgang unter Vakuum erfolgen. Um die Entgasung möglichst vollständig zu machen, ist eine lange Zeit zur Evakuierung notwendig, und die Durchtränkung mit Gießharz ist wegen der großen Eindringtiefe, insbesondere des Durchlaßwiderstandes in Schichtrichtung, schwerlich vollständig und im übrigen unkontrollierbar.Process for the production of a wound condenser bushing with inlaid metallic control linings It is known that capacitor bushings to be impregnated with casting resin. Should the impregnation be of high quality, the finished condenser bushing must be evacuated and the impregnation process under Vacuum. To make the degassing as complete as possible, it takes a long time Evacuation time is necessary, and the impregnation with cast resin is because of the large penetration depth, in particular the forward resistance in the direction of the layer, hardly complete and otherwise uncontrollable.
Es ist auch bekannt, Hohlkörper aus Gießharz im Schleudergußverfahren und unter Vakuum herzustellen, um einen blasenfreien Guß zu erhalten bzw. Oxydation oder Dipolymerisation zu verhindern.It is also known to produce hollow bodies made of cast resin by centrifugal casting and manufacture under vacuum in order to obtain a bubble-free casting or oxidation or to prevent dipolymerization.
Die vorliegende Erfindung befaßt sich dagegen mit einem Verfahren zur Herstellung von Kondensatordurchführungen mit metallischen Steuerbelägen unter Vakuum. Dabei trägt erfindungsgemäß die auf der Vorratsrolle aufgewickelte Papierbahn die metallischen Steuerbeläge bereits in umgekehrter Reihenfolge wie bei der fertigen Kondensatordurchführung, und es werden beim Umwickeln dieser Papierbahn auf den in einem Gießharzbad umlaufenden Wickeldorn, die Vorratsrolle und der Dorn in einem gemeinsamen Behälter unter Vakuum gehalten. Um dabei ein Verrutschen der metallischen Beläge zu verhindern, erweist es sich als zweckmäßig, diese Beläge bei der Herstellung der mit umgekehrtem Wickelsinn aufgewickelten Durchführung leicht auf dem Papier festzukleben.The present invention, however, is concerned with a method for the production of condenser bushings with metallic control linings under Vacuum. According to the invention, the paper web wound on the supply roll carries the metallic control linings already in reverse order as with the finished one Condenser bushing, and it will be when wrapping this paper web on the In a cast resin bath revolving winding mandrel, the supply roll and the mandrel in one common container kept under vacuum. In order to prevent the metallic from slipping To prevent deposits, it proves to be useful to these coverings in the production the lead-through, which is wound in the opposite direction, lightly on the paper to glue on.
Damit die Gießharzmenge möglichst klein gehalten werden kann, ist es vorteilhaft, den Wickeldorn in einer Wanne anzuordnen, die nicht viel größer ist als die herzustellenden Wickelzylinder und die deren Umfang weitgehend angepaßt ist.So that the amount of casting resin can be kept as small as possible it is advantageous to arrange the winding mandrel in a tub that is not much larger is largely adapted as the winding cylinder to be produced and the scope thereof is.
Das Umwickeln von einem Vorratsdorn ist an sich bereits bekannt, jedoch werden nach den bekannten Verfahren die Steuerbeläge erst bei diesem Umwickeln eingelegt. Hingegen ermöglicht das Einlegen der Steuerbeläge bereits auf dem Vorratsdorn in umgekehrter Reihenfolge, daß das Umwickeln bei dem neuen Verfahren mit einfachen Mitteln in einem geschlossenen Vakuumgefäß erfolgen kann, so daß eine einwandfreie Evakuierung und Imprägnierung der fertigen Kondensatordurchführungen jederzeit gewährleistet ist.The wrapping of a supply mandrel is already known per se, however the tax pads are only inserted during this wrapping according to the known method. On the other hand, you can insert the tax pads on the supply mandrel in reverse order that the wrapping in the new process with simple Means can be done in a closed vacuum vessel, so that a proper Evacuation and impregnation of the finished condenser bushings guaranteed at all times is.
Eine Anordnung zur Durchführung des neuen Verfahrens ist in der Figur schematisch dargestellt. Dabei ist mit 1 der Vakuumbehälter und mit 2 das Gießharzbad bezeichnet. 3 stellt die mit metallischen Steuerbelägen 4 in umgekehrter Reihenfolge versehene Papierbahn dar, die zuvor beispielsweise in Luft mit umgekehrtem Wickelsinn auf die Vorratsrolle aufgewickelt worden ist. Diese Papierbahn wird dann auf den im Gießharzbad laufenden Wickeldorn 5 umgewickelt, wodurch man dann die fertige Kondensatordurchführung erhält. Die mit umgekehrtem Wickelsinn auf der Vorratsrolle aufgewickelte und in. Richtung auf den Wickeldorn zu laufende Papierbahn wird somit auf dem Weg von der oberen Vorratsrolle zum unteren Wickeldorn entgast und taucht anschließend in das Gießharz, so daß sie beim Aufwickeln praktisch keine Lufteinschlüsse mehr enthält.An arrangement for carrying out the new method is shown in the figure shown schematically. 1 is the vacuum container and 2 is the cast resin bath designated. 3 represents those with metallic control linings 4 in reverse order provided paper web is that previously, for example, in air with reverse winding has been wound onto the supply roll. This paper web is then on the winding mandrel 5 running in the cast resin bath, which then makes the finished Condenser bushing receives. The one with the reverse winding direction on the supply roll The paper web wound up and running in the direction of the winding mandrel is thus degassed and immersed on the way from the upper supply roll to the lower winding mandrel then into the casting resin, so that there are practically no air pockets when it is wound up contains more.
