Description
Elektrolytischer Wickelkondensator Die Erfindung betrifft einen elektrolytischen Wickelkondensator mit streifenförmigen Belegungen und streifenförmigen, freiliegende, tränkfähige Kanten aufweisenden, mit dem Elektrolyten durchgehend getränkten Trennschichten zwischen diesen Belegungen.Electrolytic wound capacitor The invention relates to an electrolytic capacitor Winding capacitor with strip-shaped assignments and strip-shaped, exposed, Separating layers which have impregnable edges and are continuously impregnated with the electrolyte between these assignments.
Es ist bereits bekannt, durch Aufwickeln von als Belegungen dienenden, z. B. aus Aluminium bestehenden Metallfolien und von z. B. aus Papier bestehenden Zwischenlagen und durch Tränken der Zwischenlagen mit einem Elektrolyten einen Elektrolytwickelkondensator herzustellen. Die Anzahl der Trennschichten entspricht bei den bekannten Kondensatoren jeweils der Anzahl der Belegungen, so daß z. B. bei Verwendung von zwei Belegungen auch zwei Trennschichten verwendet werden, wobei zwischen je zwei Belegungen jeweils eine Trennschicht angeordnet ist. Die Größe der Trennschichten und der Belegungen kann hierbei so bemessen sein, daß die Trennschichten über die Belegungen überstehen und von dort aus mit dem Elektrolyten getränkt werden können.It is already known, by winding up serving as occupancies, z. B. made of aluminum metal foils and of z. B. made of paper Intermediate layers and, by impregnating the intermediate layers with an electrolyte, an electrolyte wound capacitor to manufacture. The number of separating layers corresponds to the known capacitors each of the number of assignments, so that, for. B. when using two assignments two separating layers can also be used, with two assignments between each a separating layer is arranged. The size of the separating layers and the occupancies can be dimensioned in such a way that the separating layers protrude beyond the coverings and from there it can be soaked with the electrolyte.
Zur Erleichterung der Tränkung der Trennschichten mit dem Elektrolyten und zur Verbesserung der Eigenschaften eines derartigen elektrolytischen Kondensators sind gemäß der Erfindung zwischen je zwei aufeinanderfolgenden Belegungen mindestens zwei mit dem Elektrolyten getränkte Trennschichten vorhanden. Bei nicht gewickelten Elektrolytkondensatoren ist es bekannt, zwischen zwei Belegungen jeweils zwei den Elektrolyten aufnehmende Trennschichten anzuwenden. Als Trennschichten sind hierbei Glasgewebe verwendet.To facilitate the impregnation of the separating layers with the electrolyte and to improve the properties of such an electrolytic capacitor are according to the invention between two consecutive assignments at least two separating layers soaked with the electrolyte are present. When not wound Electrolytic capacitors are known between two assignments apply two separating layers each absorbing the electrolyte. As separating layers glass fabrics are used here.
Bei einer weiteren nicht gewickelten Ausführung sind zwischen den beiden Elektroden außer zwei mit Elektrolyt getränkten Stahlwolleschichten noch zwei aus absorbierendem Werkstoff, wie Papier oder Gewebe, bestehende Trennschichten vorgesehen.In another non-wound version, between the two electrodes apart from two layers of steel wool soaked in electrolyte two separating layers made of absorbent material such as paper or fabric intended.
Die erfindungsgemäße Verwendung mehrerer Trennschichten zwischen je zwei auf einanderfolgenden Belegungen an Stelle einer einzigen hat folgende Vorteile: Man kann die Schichten aus besonders dünnem Papier herstellen, so daß die Dicke der Zwischenlage trotz Anwendung von mehreren Schichten nicht größer ist als bei Anwendung einer einzigen. Es werden aber dennoch die schädlichen Auswirkungen von Fehlern oder Inhomogenitäten, z. B. eines Loches, in einer der Trennschichten vermieden, da bei der Übereinanderlegung von zwei oder mehreren Trennschichten die höchste Wahrscheinlichkeit besteht, daß zwei solche Löcher in den Trennschichten gerade nicht übereinanderliegen. Hierdurch wird die Homogenität der aus mehreren Trennschichten bestehenden Zwischenlage wesentlich vergrößert und erreicht, daß die Verteilung des Elektrolyten auf die Flächenteile der Kondensatorbelegungen im fertigen mit dem Elektrolyten getränkten Kondensator sehr gleichmäßig ist. Durch eine solche gleichmäßige Elektrolytverteilung werden die Eigenschaften eines Elektrolytkondensators, insbesondere die Spannungsfestigkeit und der Verlustfaktor, wesentlich verbessert.The inventive use of several separating layers between each two consecutive assignments instead of a single one has the following advantages: You can make the layers from particularly thin paper, so that the thickness the intermediate layer is not larger than with Application of a single. However, the harmful effects of Defects or inhomogeneities, e.g. B. a hole, avoided in one of the separating layers, because when two or more separating layers are placed on top of each other, the highest There is a likelihood that two such holes in the release liners are straight do not lie on top of each other. This increases the homogeneity of the multiple separating layers existing intermediate layer is significantly enlarged and achieves that distribution of the electrolyte on the surface parts of the capacitor assignments in the finished with the electrolyte-soaked capacitor is very uniform. By such a uniform electrolyte distribution are the properties of an electrolytic capacitor, especially the dielectric strength and the dissipation factor are significantly improved.
Außerdem kann der Elektrolyt in eine doppelte Schicht viel besser eintreten als in eine einfache. Der Elektrolyt kann nämlich zwischen den beiden dünnen Schichten hindurchtreten und somit von innen und von außen in diese eindringen. Darüber hinaus wird ein dünnes Papier viel leichter vollständig durchtränkt als ein dickeres. Schließlich hat man dabei die Möglichkeit, in für Wickelkondensatoren ohne Elektrolyten an sich bekannter Weise sogar untereinander verschiedene Papiersorten in einer zwischen zwei aufeinanderfolgenden Belegungen angeordneten Zwischenlage zu vereinigen. Beispielsweise ein sehr poröses und saugfähiges Papier mit einem sehr dichten, festen und darum weniger saugfähigen Papier.In addition, the electrolyte can do much better in a double layer enter as a simple one. The electrolyte can namely between the two pass through thin layers and thus penetrate into them from the inside and outside. In addition, a thin paper is much more easily soaked through completely than a thicker one. Finally, you have the option of using wound capacitors without electrolytes, in a manner known per se, even different types of paper from one another in an intermediate layer arranged between two successive assignments to unite. For example, a very porous and absorbent paper with a very dense, firm and therefore less absorbent paper.
Die Verwendung von mehreren Trennschichten zwischen je zwei aufeinanderfolgenden Belegungen hat besondere Bedeutung für Elektrolytkondensatoren, deren Elektrolyt aus einer bei einer Temperatur von etwa go bis 1o5° C behandelten Mischung von Glyzerin und Borax besteht und daher verhältnismäßig zähflüssig ist.The use of several separating layers between each two successive ones Allocation is of particular importance for electrolytic capacitors, their electrolyte from a mixture of glycerine treated at a temperature of about 10 to 10 ° C and borax and is therefore relatively viscous.
