Description
Elektrischer Wickelkondensator mit einem Dielektrikum aus Polymerisationsprodukten oder Halogeniden des Vinyls bzw. des Styrols Gegenstand der vorliegenden Erfindung ist ein `Vickelkondensator, bei dem als Dielektrikum Polymerisationsprodukte oder Halogenide des Vinyls bzw. des Styrols Verwendung fin.3en.Electrical wound capacitor with a dielectric made of polymerisation products or halides of vinyl or of styrene are the subject of the present invention is a `Vickel capacitor in which polymerisation products or Halides of vinyl or styrene use fin.3en.
Diese Isolierstoffe besitzen bekanntlich Eigenschaften, die sie für Kondensatoren wegen der dem Glimmer ähnlichen Verlustfreiheit sehr geeignet machen. In der Hauptsache werden mit den nur in verhältnismäßig kurzen Längen erhältlichen Isolierstoffen Schichtkondensatoren hergestellt. Um auch Wickelkondensatoren herzustellen, kann man nach dem bekannten Verfahren eine Papierbahn als Träger und Verfestigungsmittel verwenden. Jedoch wird durch die -hierbei in Wirkung tretende Dielektrikumkombination (Isolierstoff L Papier) der Verlustwinkel stark erhöht.These insulating materials are known to have properties that they are used for Make capacitors very suitable because of the lack of loss, similar to mica. Mainly with the only available in relatively short lengths Layered capacitors are made of insulating materials. In order to also manufacture wound capacitors, you can use a paper web as a carrier and solidifying agent according to the known method use. However, due to the dielectric combination that comes into effect here (Insulating material L paper) the loss angle is greatly increased.
Um dies zu vermeiden, muß das Papier als Dielektrikum möglichst ausgeschaltet werden. Dies geschieht in der Weise, daß gemäß der Erfindung die Belegungen und die als Dielektrikum dienenden Vinyl- bzw. Styrolblätter höchstens eine Windung aufweisen, und daß eine Papierbahn, deren Anfang und Ende noch in mehreren Lagen als Schutzhülle für den Kondensator gewickelt sind, lediglich als Träger- und Verfestigungsmittel für die Belegungen und das Dielektrikum dient. Die Herstellung eines derartigen Kondensators vollzieht sich folgendermaßen: Zunächst werden auf einem entsprechend starken Wikkeldorn mehrere Lagen Papier aufgebracht, dann folgt die Metallfolie unter Zwischenlegung des als Dielektrikum dienenden Isolierstoffmaterials. Daraufhin wird Papier zur Hervorrufung einer Schutzschicht mehrere Male um die eigentlichen Belegungen gewickelt.To avoid this, the paper must be switched off as a dielectric if possible will. This is done in such a way that, according to the invention, the assignments and the vinyl or styrene sheets serving as dielectric at most one turn have, and that a paper web, the beginning and end of which are still in several layers are wound as a protective cover for the capacitor, only as a carrier and solidifying agent is used for the assignments and the dielectric. The production of such a Capacitor works like this: First, be on a accordingly Several layers of paper are applied to a strong winding mandrel, followed by the metal foil with the interposition of the insulating material serving as the dielectric. Thereupon is used to create a protective layer several times around the actual paper Assignments wrapped.
Diese in der Abbildung gezeigte Ausführungsform wird mit Vorteil da benutzt, wo verhältnismäßig kleine Kapazitäten erfordersich sind. Eine Änderung der Kapazitätsgröße solcher Kondensatoren kann z. B. durch verschiedene Größe des Wickeldorns und eine verschiedene Anzahl erster Papierlagen herbeigeführt werden.This embodiment shown in the figure is advantageous there used where relatively small capacities are required. A change the capacitance size of such capacitors can be, for. B. by different size of the Winding mandrel and a different number of first paper layers are brought about.
Da die Isolierstoffblättchen eine ziemliche Sprödigkeit aufweisen, empfiehlt es sich, sie erfindungsgemäß vor dem Wickeln entsprechenden Weichmachungsmitteln auszusetzen, so daß die Zwischenlage während des Wikkelns weich und anschmiegsam wird und sich der Formgestaltung des Wickeldornes anpaßt. Nach dem Wickeln wird der Kondensator gemäß der Erfindung erwärmt und evakuiert, damit die beim Weichmachen der Isolationszwischenlage eingedrungene Feuchtigkeit wieder entfernt wird. Die Abbildung zeigt' schematisch einen Längsschnitt durch solchen Kondensator.Since the insulating flakes are quite brittle, it is advisable, according to the invention, to use appropriate plasticizers prior to winding suspend, so that the intermediate layer soft and supple during winding and adapts to the shape of the winding mandrel. After swaddling will be the condenser according to the invention is heated and evacuated so that the softening moisture that has penetrated the insulation layer removed again will. The figure shows a schematic longitudinal section through such a capacitor.
Mit i ist die Papierbahn bezeichnet, die zunächst während des Wickelns in mehrfachen Lagen auf den Wickeldorn aufgespult wird. Dann werden .auf die Papierbahn die Metallfolien z und q. unter Zwischenlegen des Isolierstoffblattes 3 gewickelt. Die Länge der Belegungen z, ¢ und der Isolierstoffzwischenlage 3 entspricht höchstens dem über der ersten aufgebrachten Papierlage gemessenen Wickeldornumfang. Nach dem Aufwickeln der Metallfolien und der Isolierstoffzwischenlage werden wiederum mehrere Lagen Papier aufgewickelt, durch die eine Schutzschicht für die Kondensatorelemente geschaffen wird.With i the paper web is referred to, which initially during the winding is wound onto the winding mandrel in multiple layers. Then .on the paper web the metal foils z and q. wrapped with the interposition of the insulating sheet 3. The length of the assignments z, ¢ and the insulating layer 3 corresponds at most the circumference of the mandrel measured over the first paper layer applied. After this Winding up of the metal foils and the insulating material intermediate layer are in turn several Layers of paper wound up, through which a protective layer for the capacitor elements is created.
