Description

Elektrischer Vielfachkondensator, bestehend aus einer Anzahl von parallel liegenden Wicklungselementen, über deren beiden Stirnseiten die als Stromanschlüsse dienenden Belegungsränder wechselseitig hinausragen Die statischen Kondensatoren großer Kapazität, wie sie z. B. zur Verbesserung des Leistungsfaktors in elektrischen Anlagen ge-. braucht werden, bestehen im allgemeinen aus einer Mehrzahl von Einzelkondensätoreri- in Form sogenannter Wicklungselemente, die parallel oder bei hohen Spannungen auch in Serie geschaltet sind. Die Wicklungselemente bestehen aus zwei zylindrisch aufgewickelten Metallfolien, welche die Kondensatorbelege bilden, und dem ebenfalls aufgewickelten Dielektrikum, das meist aus einigen übereinander befindlichen Papierlagen besteht. Die Wicklungselemente werden durch geeignete Tragkonstruktionen zu vielen zu einem größeren Kondensator vereint. Meist sind diese eingetaucht in Isolieröl oder auch in eine eingießbare, hernach erstarrende Isoliermasse. Bei hohen Spannungen werden mehrere Wicklungselemente in Serie geschaltet. Zwecks Ermöglichung der Stromzufuhr zu den Elementen läßt man oft die eine eingewickelte Metallfolie, einen Pol darstellend, auf der einen Stirnseite etwas vorstehen, die andere Folie, den Gegenpol darstellend, auf der entgegengesetzten Stirnseite. Aus Fig. r, welche einige parallel liegende, in Serie geschaltete Wicklungselemente darstellt, ist ersichtlich, daß zwischen den einander benachbarten Stirnseiten, die nicht miteinander" verbunden sind, je die doppelte Elementenspannung auftritt, so zwischen z und 2 links, zwischen 2 und 3 rechts usw. Bei kleinem gegenseitigen. Abstand der Elemente, wie er aus Erspärriisgründen sonst vorteilhaft wäre, besteht zu geringe Sicherheit gegen den elektrischen Durchschlag an den genannten Stellen. Zur Vergrößerung des Abstandes könnten die Elemente nach Fig.2 in ihrer Achsrichtung so weit gegenseitig verschoben werden, daß die Abstände zwischen benachbarten Polen groß genug sind. Dies führt jedoch zu unpraktischen Gesamtanordnungen. Die Kesselvolumen würden schlecht ausgenützt, die Elemententräger 5 würden eine schiefe Lage einnehmen und müßten daher mechanisch fester sein als in vertikaler Lage wegen der auf Durchbiegung wirkenden Kraftkomponenten. Dreht man die Anordnung nach Fig. 2 jedoch um den Winkel a, so erhält man die Anordnung nach Fig. 3, welche den Vorteil der vergrößerten Frontabstände der Wickelelemente verbindet mit der Möglichkeit vertikal hängender Elemententräger. Gegenstand der vorliegenden Erfindung ist daher ein elektrischer Vielfachkondensator, bestehend aus einer Anzahl von parallel liegenden Wicklungselementen, über deren beiden Stirnseiten die als Stromanschlüsse dienenden Belegungsränder wechselseitig hinausragen; erfindungsgemäß sind die Wickelachsen gegen die Horizontale geneigt und liegen korrespondierende Stellen übereinander angeordneter Wickel vertikal übereinander. Die Elemententräger können dann vertikal stehende Konstruktionsgebilde sein. Gegenüber den bekannten Anordnungen mit horizontalen oder vertikalen, parallelen Wickelelementen bietet die vorgeschlagene Anordnung in elektrischer Hinsicht den Vorteil der großen Frontabstände benachbarter Elemente einerseits, in mechanischer Hinsicht den gleichen Vorteil, den horizontale Wickelelemente bieten, indem an Konstruktionsmaterial für das Traggestell gespart wird.Electrical multiple capacitor consisting of a number of in parallel lying winding elements, over the two end faces as power connections The edges of the covering that serve to protrude alternately The static capacitors large capacity, such as B. to improve the power factor in electrical Plants. generally consist of a plurality of individual condenser units in the form of so-called winding elements that run parallel or at high voltages are connected in series. The winding elements consist of two cylindrically wound Metal foils, which form the capacitor covers, and the one that is also wound up Dielectric, which usually consists of a few layers of paper on top of each other. The winding elements become many into one through suitable supporting structures larger condenser united. Mostly these are immersed in insulating oil or also in a pourable, afterwards solidifying insulating compound. At high voltages will be several winding elements connected in series. In order to enable the power supply to the elements one often leaves a wrapped metal foil, representing a pole, protrude slightly on one end, the other foil, representing the opposite pole, on the opposite face. From Fig. R, which shows some parallel, represents winding elements connected in series, it can be seen that between the adjacent end faces that are not "connected to each other," depending twice the element tension occurs, so between z and 2 on the left, between 2 and 3 on the right and so on. Distance of the elements, as it was for reasons of savings otherwise it would be advantageous if there is insufficient security against electrical breakdown at the named places. To increase the distance, the elements could after 2 are mutually shifted so far in their axial direction that the distances between neighboring poles are large enough. However, this leads to impractical Overall arrangements. The boiler volume would be poorly used, the element carriers 5 would assume an inclined position and would therefore have to be mechanically stronger than in a vertical position because of the force components acting on deflection. Turns however, if the arrangement according to FIG. 2 is rotated by the angle α, the arrangement is obtained according to Fig. 3, which has the advantage of the enlarged front spacing of the winding elements combines with the possibility of vertically hanging element carriers. Subject of Therefore, the present invention is an electrical multiple capacitor consisting from a number of parallel winding elements over both of their end faces the occupancy edges serving as power connections alternate protrude; according to the invention, the winding axes are inclined to the horizontal and are corresponding Place superimposed wraps vertically on top of each other. The element carriers can then be vertically standing structures. Compared to the known Offers arrangements with horizontal or vertical, parallel winding elements the proposed arrangement in electrical terms has the advantage of the large front clearances neighboring elements on the one hand, in mechanical terms the same advantage, provide the horizontal winding elements by adding construction material for the support frame is saved.

Bekanntlich steigen die Verluste der Kondensatoren mit der Temperatur derselben: Es muß also dafür gesorgt werden, daß das die Wickel umhüllende flüssige Dielektrikum_ möglichst geringe Temperaturerhöhungen annimmt. Bei horizontaler Anordnung der Wickel ist eine Ölzirkulation im Inneren und an der Oberfläche derselben bei den geringen Temperaturdifferenzen nicht möglich, wohl aber bei vertikaler und auch schiefer Anordnung der Wickel. Die geneigte Anordnung der Wickel hat deshalb in elektrischer Beziehung dieselben Vorteile wie die vertikale Anordnung derselben. Fig, q. zeigt ein Ausführungsbeispiel des Vielfachkondensators gemäß der Erfindung. Die Wickelelemente i sind dabei kreiszylindrisch geformt. Es bedeuten i die hier zylindrisch geformten Wickelelemente, z und 3 die an den Enden- vorstehenden metallischen Belegränder mit zugehörigen Anschlußkontakten, q. ein zentrales Tragrohr, 5 die vertikalen, hier im Querschnitt U-förmigen Elemententräger, 6 die Serienverbindungen der einzelnen Wickelelemente, 7 den Kessel, 8 den Deckel, 9 die Durchführungsisolatoren, io die isolierende Flüssigkeit. Man sieht deutlich, daß durch die Schiefstellung der Wickelelemente ein vergrößerter Abstand der Enden :2 und 3 erreicht wird sowie eine Ölzirkulation gewährleistet wird.It is well known that the losses in capacitors increase with temperature the same: It must therefore be ensured that the liquid enveloping the compresses Dielektrikum_ assumes the lowest possible temperature increases. With a horizontal arrangement the winding is an oil circulation inside and on the surface of the same The small temperature differences are not possible, but it is possible with vertical and also oblique arrangement of the coils. The inclined arrangement of the winding has therefore in electrical relationship the same advantages as the vertical arrangement thereof. Fig, q. shows an embodiment of the multiple capacitor according to the invention. The winding elements i are shaped like a circular cylinder. I mean this here cylindrically shaped winding elements, z and 3 the metallic ones protruding at the ends Margins of documents with associated connection contacts, q. a central support tube, 5 the vertical element carrier, here with a U-shaped cross-section, 6 the series connections of the individual winding elements, 7 the boiler, 8 the cover, 9 the bushing insulators, io the insulating liquid. You can clearly see that through the misalignment of the winding elements an increased distance between the ends: 2 and 3 is achieved as well an oil circulation is guaranteed.
