Description
Kühleinrichtung an viellagigen Starkstromkondensatoren, deren Metallbelegungen abwechselnd an entgegengesetzten Seiten über den Kondensatorkörper in ein den Kondensator umgebendes, flüssiges Isolier- und Kühlmedium hinausgeführt sind Bei Starkstromkondensatoren für Dauerbetrieb ist eine gewisse @r`varmung unvermeidlich. Es ist bekannt, zur Vermeidung dieser Erwärmung in den Elektroden- Kühlkanäle auszusparen, um durch diese Kühlöl zur Vermeidung örtlicher Wärmestauungen hindurchstreichen zu lassen. Dieses Verfahren hat, zumal bei Kondensatoren für mäßige Spannungen, den Nachteil, daß die Anordnung der Kühlkanäle Platz erfordert und sie außerdem in der Herstellung Schwierigkeiten machen.Cooling device on multi-layer high-voltage capacitors, their metal coatings alternately on opposite sides over the capacitor body into the capacitor surrounding, liquid insulating and cooling medium are led out a certain @r`warming is inevitable for continuous operation. It is known to Avoidance of this heating in the electrode cooling channels to cut through to allow this cooling oil to pass through to avoid local heat build-up. This method has the disadvantage, especially in the case of capacitors for moderate voltages, that the arrangement of the cooling channels requires space and they also in the production Make trouble.
E5 ist auch bekannt, gewickelte oder geschichtete Kondensatoren dadurch zu kühlen, daß man die Elektroden je einer Polarität über je eine Seite des Isolationsmaterials herausstehen läßt, so daß sie frei im Kühlinittel angeordnet sind und durch (las meist flüssige Isolätionsmaterial, wie Ü1, gekühlt werden.E5 is also known to make wound or layered capacitors to cool that one the electrodes each one polarity on each side of the insulation material can protrude so that they are freely arranged in the coolant and through (read mostly liquid insulation material, such as Ü1, are cooled.
Bei Kondensatoren, welche aus zahlreichen Schichten aufgebaut sind, befriedigt aber auch diese Kühlmethode nicht. Die Erfindung beruht auf der Erkenntnis, daß eine große Anzahl nebeneinanderliegender, in geringem Abstand befindliche Metallschichten eine Wärmeisolierwirkung auch dann aufweist, wenn die Zwischenräume mit flüssigem 0I gefüllt sind. Die Ursache dieser Erscheinung beruht darauf, daß die Anwesenheit der vielen Metallfolien durch die Zähigkeitswirkung die Ölströmung hindert. Sofern das ü1 aber nicht unter dem Einfluß der Temperaturunterschiede, bzw. unter der durch diese veranlaßte Volumenänderung zu strömen vermag, ist der W,irmetransport sehr schlecht.In the case of capacitors, which are made up of numerous layers, however, this cooling method is not satisfactory either. The invention is based on the knowledge that a large number of adjacent, closely spaced metal layers has a heat insulating effect even if the interstices with liquid 0I are filled. The cause of this phenomenon is based on the presence of the many metal foils prevents the flow of oil due to the toughness effect. Provided the ü1 but not under the influence of the temperature differences, or under the through This induced change in volume is able to flow, the heat transport is very much bad.
Die Erfindung betrifft daher eine Kühleinrichtung an viellagigen Starkstromkondensatoren, deren Metallbelegungen abwechselnd an entgegengesetzten Seiten über den Kondensatorkörper in ein den Kondensatorkörper umgebendes flüssiges Isolier- und Kühlmedium hinausgeführt sind; erfindungsgemäß sind die frei herausragenden Ränder der Metallbelegungen, zwecks Erleichterung der Ölströmung zwischen den einzelnen Lagen und damit der Ölkühlung, gelocht oder geschlitzt. Die Anordnung von Schlitzen kann nebenher auch noch den Vorteil haben, daß z. B. bei rund gewickelten Kondensatoren das Zusammenklemmen der Metallbelegungen zur Erzielung der an sich bekannten Stromabnahme an dieser Stelle erleichtert wird.The invention therefore relates to a cooling device on multi-layer high-voltage capacitors, their metal deposits alternately on opposite sides over the capacitor body led out into a liquid insulating and cooling medium surrounding the capacitor body are; according to the invention are the freely protruding edges of the metal coverings, to facilitate the oil flow between the individual layers and thus the oil cooling, perforated or slotted. The arrangement of slots can also be used alongside Have the advantage that z. B. with round wound capacitors clamping together the metal deposits to achieve the known power consumption on this Position is facilitated.
Die Abb. i zeigt eine Ausführungsform der Kühleinrichtung gemäß der Erfindung iin Schnitt, die Abb. 2 in der Ansicht, und zwar an einem rund gewickelten Kondensator. Die eine Belegung 13i steht in bekannter Weise nach oben in die Isolierflüssigkeit vor, während die andere, L., nach unten ragt.Fig. I shows an embodiment of the cooling device according to FIG Invention iin section, Fig. 2 in view, on a round wound Capacitor. One occupancy 13i is in a known manner upward into the insulating liquid in front, while the other, L., protrudes downwards.
Um nun bei Kondensatoren, welche viele Lagen enthalten, die mangelhafte Kühlwirkung dieser Einrichtung zu verbessern, werden erfindungsgemäß die Ränder der Metallbelegungen in geeigneter Weise gelocht, z. B. mittels der Löcher L in Abb. i, wodurch eine wenigstens einigermaßen freie Ölströmung zwischen den Folien ermöglicht wird. Anstatt dessen ist es auch möglich, die Ränder der Metallbelegungen zu schlitzen, wie (lies in Abb. a dargestellt ist.In the case of capacitors, which contain many layers, the defective To improve the cooling effect of this device, according to the invention, the edges the metal coverings perforated in a suitable manner, e.g. B. by means of the holes L in Fig. I, whereby an at least somewhat free flow of oil between the foils is made possible. Instead, it is also possible to use the edges of the metal coverings to slit, as shown in Fig. a.
