Description

Verfahren zum Herstellen von gewickelten Kondensatoren, deren Material vor dem Wickeln mit Isoliermittel getränkt wird Zur Verbesserung des Leistungsfaktors von Starkstromnetzen werden vielfach Kondensatoren verwendet. Die Kapazität der Kondensatoren nimmt quadratisch mit der Spannung ab und ist wesentlich abhängig von dem Abstand der Belege. Die Kondensatoren werden also besonders für Niederspannung sehr groß und bei Verwendung hochwertiger Isolierstoffe als Zwischenlagen zwischen den Belegen sehr teuer. Stellt man die Zwischenlagen aus billigem Isolierstoff, wie Papier o. dgl., her, so besteht die Möglichkeit, daß infolge von Lufteinschlüssen, die bei normaler Fabrikation nicht vermieden werden können, das Dielektrikum leicht durchschlägt. Es ist -daher von großer Wichtigkeit, bei wirtschaftlicher Herstellung der Kondensatoren auf das Herstellungsverfahren besonders Wert zu legen. Im allgemeinen erfolgt deren Herstellung in der Weise, daß einige Lagen Papier- mit dazwischenliegender Folie gewickelt, unter Va_ kuum._,geträ@kt,. .zusammengepreßt--ündmit geeignetem Isoliermaterial ausgegossen werden. Das Wickeln des mit der - Metallfolie versehenen Papierbandes erfolgt hierbei auf einer besonderen Wickelmaschine in Luft, wobei es sich aber selbst unter Verwendung von bestem Papier nicht vermeiden läßt, daß kleine Luftblasen zwischen der Metallfolie und der Papierlage eingeschlossen werden. Diese eingeschlossenen Luftblasen, auf der sich der größte Teil des Potentialunterschiedes konzentriert, führen dann durch langsame Ionisation zur Verschlechterung der Isolation, zu höherer Erwärmung und letzten Endes zum Durchschlag. Zur Vermeidung dieser Schwierigkeiten hat man das Papier während des Aufwickelns in einem Ölbade zusammengepreßt sowie das Papier bereits vor dem Wickeln unter Vakuum mit Öl getränkt oder auch das gewikkelte Band nicht zusammengepreßt, sondern nach dem Wickeln lose unter Öl gesetzt, wobei das Öl die zwischen den einzelnen Belegungen eingeschlossenen Luftblasen allmählich verdrängen kann. Ein derartiges Verfahren ,aber hat neben vergrößertem Raumbedarf noch den Nachteil, daß die Kapazität der Kondensatoren nicht genau festgelegt werden kann, da der Abstand zwischen den einzelnen Metallfolien nicht dauernd konstant bleibt, sondern etwas veränderlich ist.Process for the manufacture of wound capacitors, their material Soaked with insulating agent before winding To improve the power factor Power networks often use capacitors. The capacity of the Capacitors decreases quadratically with the voltage and is significantly dependent on the distance between the documents. The capacitors are so especially for low voltage very large and when using high-quality insulating materials as intermediate layers between the receipts very expensive. If you make the intermediate layers made of cheap insulating material, like paper or the like, there is the possibility that as a result of air inclusions, which cannot be avoided with normal fabrication, the dielectric easily hits through. It is therefore of great importance in economic production of the capacitors to attach particular importance to the manufacturing process. In general they are produced in such a way that some layers of paper with intervening Foil wrapped, under vacuum ._, soaked ,. .compressed - and with a suitable Insulating material to be poured out. The winding of the one provided with the - metal foil Paper tape takes place here on a special winding machine in air, whereby but it cannot be avoided, even with the best paper, that small air bubbles become trapped between the metal foil and the paper layer. These trapped air bubbles on which most of the potential difference is concentrated, then lead to deterioration of the insulation due to slow ionization, to higher heating and ultimately to breakdown. To avoid these difficulties if the paper was pressed together in an oil bath while it was being wound up, as well as the paper or the wrapped paper is soaked in oil under vacuum before winding Tape not compressed, but loosely put under oil after winding, whereby the oil gradually removes the air bubbles trapped between each layer can displace. Such a method, however, has an increased space requirement nor the disadvantage that the capacitance of the capacitors cannot be precisely determined can, since the distance between the individual metal foils is not constantly constant remains, but something is changeable.

Die Erfindung betrifft nun ein Verfahren zum Herstellen von gewickelten Kondensatoren, das die erwähnten Nachteile vermeidet.The invention now relates to a method for producing wound Capacitor, which avoids the disadvantages mentioned.

Gemäß der Erfindung wird dies dadurch erreicht, daß das in einem von der Wickelvorrichtung getrennten-- Tränkkessel imprägnierte und darauf unter einer isolierenden Flüssigkeit aufgewickelte Material beim Wi#kkeln unter--:.Vakuum steht. Das urfwiclzeln wes Kondensators kann auch dadurch verbessert werden, daß das Papierband vor dem Aufwickeln unter eine Zugspannung gesetzt wird, die entsprechend den jeweiligen Betriebsverhältnissen einstellbar sein kann. Der Isolierkern, auf den das Papier gewickelt wird, ist zweckmäßig oval ausgebildet. Durch Anwendung von Vakuum während des WikkeIns wird der Vorteil erzielt, daß Lufteinschlüsse in dem Wickel mit absoluter Sicherheit vermieden werden, so daß der fertige Kondensator ein außerordentlich homogenes Dielektrikum erhält und seine Durchschlagsspannung beträchtlich gesteigert wird. Außerdem ergibt sich hierdurch eine besonders gedrängte Bauart mit geringem Platzbedarf.According to the invention this is achieved in that the in one of the winding device separate - impregnated impregnation kettle and on top of it wrapped material under an insulating liquid while wrapping under -: vacuum is. The rolling of the capacitor can also be improved by this that the paper tape is put under tension before winding, which can be adjusted according to the respective operating conditions. Of the The insulating core on which the paper is wound is expediently oval in shape. By using a vacuum during the WikkeIns the advantage is achieved that air pockets in the winding can be avoided with absolute certainty, so that the finished capacitor an extremely homogeneous dielectric and its breakdown voltage is increased considerably. In addition, this results in a particularly compact one Construction with little space requirement.
