Description

Elektrischer Kondensator, insbesondere aus gewickelten Elementen aufgebauter Kondensator, mit parallel geschalteten Kondensatorelementen Die Erfindung betrifft einen elektrischen Kondensator, insbesondere einen ausgewickelten Elementen aufgebauten Kondensator, mit parallel geschalteten Kondensatorelementen.Electrical capacitor, in particular made up of wound elements Capacitor, with capacitor elements connected in parallel The invention relates to an electrical capacitor, in particular a developed element Capacitor, with capacitor elements connected in parallel.

Bei Wickelkondensatoren treten insofern Schwierigkeiten auf, als die in dem Wickel enthaltenen, die Elektroden bildenden Metallfolien an seitlich angebrachten Leitungen angeschlossen werden müssen. Auch bei parallel geschalteten Kondensatorwickeln hat man bisher an die einzelnen Metallbeläge Anschlüsse gelegt und diese dann in Reihe geschaltet. Auch wurde bereits vorgeschlagen, Kondensatorwickel in der Weise herzustellen, daß man die Elektrodenbahnen um 9o° gegeneinander versetzt jeweils unter Zwischenfugen von Isolierplatten wickelt. Die bekannten Anordnungen haben jedoch den Nachteil, daß zum Parallel- oder in Reiheschalten der einzelnen Wickel Hilfskörper erforderlich sind, die zu Spannungsverlusten Anlaß gebende i_'bergangswiderstände mit sich bringen.With wound capacitors difficulties arise as the contained in the winding, the electrodes forming metal foils attached to the side Lines must be connected. Even with capacitor windings connected in parallel So far, connections have been made to the individual metal coverings and then in Connected in series. It has also already been proposed to use capacitor winding in the manner to produce that the electrode tracks are offset from one another by 90 ° wraps under intermediate joints of insulating panels. Have the known arrangements however, the disadvantage that for parallel or series connection of the individual winding Auxiliary bodies are required, the transition resistances giving rise to voltage losses entail.

Gemäß der vorliegenden Erfindung wird das Parallelschalten von Wickelkondensatoren dadurch beträchtlich vereinfacht, daß die aus Folien und Isolierstoffbahnen aufgebauten Elemente derart gewickelt sind, daß die eine der zwischen Isolierstoffbahnen befindlichen Folien in Nähe der einen Kante oder breiten Mantelfläche des Wickels und die andere in Nähe der anderen Kante blank liegt, und zwar zu beiden Seiten des Wickels. Die Isolierstoff- und Folienbahnen sind sämtlich im gleichen Sinne zu einem Wickel zusammengewickelt, und die freien Enden der Folien- und Isolierstoffbahnen überlappen sich, so daß die eine Elektrode an der einen Kante des Wickels und die andere Elektrode an der anderen Kante des Wickels von deren breiten Mantelfläche endigt und dort durch Einbringen von Fenstern in die Isolierstoffbahnen blank gelegt ist.According to the present invention, the parallel connection of wound capacitors considerably simplified by the fact that they are made up of foils and strips of insulating material Elements are wound in such a way that the one located between the insulating material webs Foils close to one edge or broad surface of the roll and the other is bare near the other edge, on both sides of the roll. the Insulating material and foil strips are all wound together to form a roll in the same way, and the free ends of the film and insulating material webs overlap, so that one electrode on one edge of the roll and the other electrode on the other edge of the roll ends by its wide lateral surface and there by introduction of windows in the insulation strips is bare.

In der Zeichnung ist ein Ausführungsbeispiel des elektrischen Kondensators nach der Erfindung dargestellt.In the drawing is an embodiment of the electrical capacitor shown according to the invention.

Der Kondensator wird durch die auseinandergerückten Wickel i, 2, 3 und q. gebildet. und 6 sind Metallfolien, die mittels der Isolierstofflagen 7 und 8 voneinander getrennt werden. Die Folie 6 (strichpunktiert) liegt bei 9 und die Folie 5 (dicker Strich) bei zo blank. In entsprechender Weise sind die übrigen Wickel ausgeführt. Beim Aufeinanderlegen der Wickel kommen dann zwischen den einzelnen Wickeln jeweils die Folien 9 auf die Folien 9 und die Folien r o auf die Folien 1o zu liegen, so daß die hondensatorwickel parallel geschaltet sind, ohne daß an den Belägen Fahnen o. dgl. angebracht werden müßten. In den Isolierstoffbahnen 7 und 8 befinden sich vorteilhaft an den Stellen 9 und 1 o Aussparungen oder Fenster, damit die Beläge 5 und 6 nicht an den Wickelkanten 11 und 12 blank liegen.The capacitor is caused by the winding i, 2, 3 and q. educated. and 6 are metal foils, which by means of the insulating layers 7 and 8 can be separated from each other. The foil 6 (dash-dotted) is at 9 and the Slide 5 (thick line) at zo blank. The other laps are in a corresponding manner executed. When the wraps are placed on top of each other, they then come between the individual In each case, wrap the foils 9 on the foils 9 and the foils r o on the foils 1o to lie so that the capacitor windings connected in parallel without flags or the like having to be attached to the coverings. In the insulation strips 7 and 8 are advantageously at points 9 and 1 o recesses or windows, so that the pads 5 and 6 are not bare on the winding edges 11 and 12.

Um ein überhitzen mehrerer parallel geschalteter Wickel zu vermeiden, empfiehlt es sich, jeden Wickel abwechselnd in die eine oder andere Windung von Kupferbändern 13 und 14 (Fig. z) zu legen. Die Kupferbänder liegen an den blanken Stellen 9 und lo der Wickel auf.To avoid overheating several coils connected in parallel, it is advisable to alternate each winding in one turn or the other Lay copper strips 13 and 14 (Fig. Z). The copper bands are on the bare ones Set up 9 and lo of the wrap.
