Description
Wassergekühlter Wickelkondensator Die Erfindung bezieht sich auf wassergekühlte Wickelkondensatoren, insbesondere für den Mittelfrequenzbetrieb.Water-cooled wound capacitor The invention relates to water-cooled Wound capacitors, especially for medium frequency operation.
Kondensatoren für Netzfrequenzen unterhalb 100 Hz lassen sich im allgemeinen betreiben, ohne daß zusätzliche Kühlmittel eingesetzt werden müssen, da bei den in diesem Falle gegebenen elektrischen Beanspruchungen die zur Verfügung stehende Gehäuseoberfläche das Abführen der erzeugten Verlustwärme gewährleistet. Mit höherer Frequenz steigen jedoch die Verluste stärker an, und es wird je nach Tränkmittel und Konstruktion früher oder später der Punkt erreicht, wo bei wirtschaftlicher Ausnutzung des Aktivmaterials eine natürliche Abführung der Verlustwärme durch die Gehäuseoberfläche nicht mehr möglich ist. Hier setzt dann die forcierende Kühlung mit Luft oder Wasser ein.Capacitors for line frequencies below 100 Hz can generally be used operate without additional coolant having to be used, as in the in this case, the electrical stresses available are those available Housing surface ensures the dissipation of the generated heat loss. With higher Frequency, however, the losses increase more, and it will depend on the impregnating agent and construction sooner or later reaches the point where it becomes more economical Utilization of the active material a natural dissipation of the heat loss through the Housing surface is no longer possible. Forcing cooling then starts here with air or water.
Es ist bekannt, zwecks Kühlung des Wickels durch den rohrförmigen Wickeldorn z. B. Wasser zu leiten, wobei dieser Wickeldorn aus Metall und Isolierstoff zusammengesetzt ist oder aber ganz aus Metall besteht. Letztere Ausführung ist hinsichtlich der Wärmeableitung günstiger. Man hat auch versucht, die Wärmeabfuhr aus dem Wickel dadurch zu verbessern, daß mittels metallischer Zwischenkontaktstücke die Wärme aus den stirnseitig überstehenden Belagfolien auf den zur Kühlung mit herangezogenen Wickeldorn übertragen wird.It is known for the purpose of cooling the roll through the tubular Winding mandrel z. B. to conduct water, this mandrel made of metal and insulating material is composed or made entirely of metal. The latter version is regarding the heat dissipation cheaper. Attempts have also been made to remove heat from the wrap to improve that by means of metallic intermediate contact pieces the heat from the covering foils protruding at the front onto the ones used for cooling Winding mandrel is transferred.
Diese erwähnten Ausführungsformen haben jedoch den grundsätzlichen Nachteil, daß die im Wickel entstehende Wärme nicht direkt, sondern über längere Zwischenstückwege, d. h. also unter nicht optimalen Kühlungsbedingungen, an die eigentlichen Kühlleitungen abgeführt wird.However, these mentioned embodiments have the basic one Disadvantage that the heat generated in the coil is not directly, but over a longer period of time Spacer paths, d. H. so under non-optimal cooling conditions, to the actual cooling lines is discharged.
Es sind auch Verfahren der Wärmeabführung bekanntgeworden, welche die Verlustwärme des Wickels über die stirnseitig überstehende Belagfolie an metallische Kühlleitungsrohre, z. B. mittels Verlöten beider. abführen. Obwohl in diesem Falle die Wärme direkt abgeführt wird, sind jedoch die überstehenden Belagfolien gebündelt und so tangential zwischen je zwei Kühlleitungen geführt und verlötet, daß dabei der größte Teil der Kühlrohroberfläche nicht zur direkten Folienkühlung ausgenutzt ist.There are also methods of heat dissipation known which the heat loss from the roll to metallic ones via the covering film protruding on the front side Cooling line pipes, e.g. B. by soldering both. dissipate. Although in this case The heat is dissipated directly, but the protruding covering foils are bundled and so tangentially guided and soldered between each two cooling lines that this Most of the cooling tube surface is not used for direct film cooling is.
Demgegenüber werden erfindungsgemäß die ausreichend weit überstehenden Windungsränder der einen Belagfolie direkt um den gesamten Umfang des ganz metallischen, z. B. für Wasserinnenkühlung geeigneten Wickeldornrohres herumgebördelt und mit diesem durch einen metallischen Druckring in optimalem ; Wärmekontakt verbunden.In contrast, according to the invention, those that protrude sufficiently far Winding edges of the one covering foil directly around the entire circumference of the completely metallic, z. B. for internal water cooling suitable mandrel tube and flanged with this by a metallic pressure ring in optimal; Thermal contact connected.
Der als Durchströmkanal ausgebildete Wickeldorn dient zugleich als mit dem Gehäuse oder mit Erde verbundener Stromleiter. Über dem Wickeldorn sitzt ein Isolierrohr, das diesen gegen die Belagfolie des Gegenpols isoliert.The winding mandrel, which is designed as a through-flow channel, also serves as a Conductor connected to the housing or to earth. Sits over the winding mandrel an insulating tube that isolates it from the covering film of the opposite pole.
Bei leistungsmäßig hoch ausgenutzten Wickeln erfolgt die Kühlung dieser zweiten, gegenpoligen Belagfolie zur Erzielung einer ebenso wirksamen Wärmeabfuhr, wie sie bei dem ersten Belag -erreicht ist derart, daß die stirnseitig in diesem Falle nur relativ kurz überstehenden Belagfolienränder sich auch wieder unmittelbar mit einem direkt gekühlten Wärmeableitkontaktblech in fester Druckverbindung befinden. Die Kühlung dieses Bleches erfolgt durch eine von einem Kühlmedium durchströmte Rohrschlange, so daß auch in diesem Falle die Wärme auf dem kürzesten Wege abgeführt wird.If the windings are used to a high degree in terms of performance, they are cooled second, opposite-pole covering foil to achieve an equally effective heat dissipation, as it is achieved with the first covering is such that the end face in this one If the covering film edges only protrude for a relatively short time, they also come back immediately are in a firm pressure connection with a directly cooled heat dissipation contact sheet. This sheet is cooled by a cooling medium flowing through it Coiled pipe, so that in this case too the heat is dissipated by the shortest route will.
Die Figuren zeigen schematisch ein Ausführungsbeispiel des Erfindungsgegenstandes, und zwar Fig. 1 einen Wickel, teilweise abgerollt, Fig. 2 den Kondensator im Achsschnitt.The figures show schematically an embodiment of the subject matter of the invention, 1 shows a roll, partially unrolled, and FIG. 2 shows the capacitor in axial section.
Gemäß Fig. 1 besteht der Kondensatorwickel aus zwei Belagfolien 1 und 2 unter Zwischenschaltung einer Dielektrikumsbahn 3 (z. B. Papierbahn). Die Belagfolien 1 und 2 sind gleich breit und derart gegeneinander versetzt, daß der Rand 4 der Folie l nur verhältnismäßig kurz über die Kante 3' der Dielektrikumsbahn, der Rand 5 der Folie 2 hingegen um einen wesentlich größeren Betrag über die andere Kante 3" der Bahn 3 übersteht. Der Wickel sitzt auf einem Wickeldorn 6, welcher aus einem Rohr aus Kupfer oder einem ähnlichen, gut wärmeleitenden antimagnetischen Material besteht. Die Endwindungen 5 sind, wie aus Fig. 2 ersichtlich, nach innen gegen den Wickeldorn 6 zu gebördelt, so daß sie in innigen metallischen Wärmekontakt mit dem Wickeldorn 6 gebracht werden können. Die Herstellung des erforderlichen Kontaktdruckes erfolgt durch ein Ringstück 7, das in der Arbeitsstellung durch eine Schraube 8 auf dem Rohr 6 gesichert ist. Die Randwindungen 4 der Folie 1 sind ebenfalls nach innen zu gebördelt, wie aus Fig.2 ersichtlich, und gegen den Nickeldorn 6 durch ein auf denselben geschobenes solierrohr 9 isoliert, das auf dieser Seite über den Nickel vorsteht. Der ganze Wickel sitzt in einem >echerförmig gebogenen Kontaktblech 10, dessen Soden 11 ebenfalls in hochwirksamem Wärmekontakt nit den umgebördelten Randwindungen 4 steht. Die Ciihlung des Bodens 11 erfolgt durch eine Kühl-;chlange 12, die in direktem Wärmeaustausch an der Außenseite des Bodens 11, der gelocht sein kann, mit 'reßdruck anliegt. Die Isolation von 10 gegenüber 6 erfolgt durch das Isolierrohr 9.According to FIG. 1, the capacitor winding consists of two covering foils 1 and 2 with the interposition of a dielectric web 3 (e.g. paper web). the Covering films 1 and 2 are of the same width and offset from one another in such a way that the Edge 4 of the film l only relatively short over the edge 3 'of the dielectric strip, the edge 5 of the film 2, however, by a much larger amount over the other Edge 3 ″ of the web 3 protrudes. The roll sits on a winding mandrel 6, which from a pipe made of copper or a similar, highly thermally conductive antimagnetic Material. As can be seen from FIG. 2, the end turns 5 are inwardly crimped against the winding mandrel 6 so that they are in intimate metallic thermal contact can be brought with the winding mandrel 6. Making the required Contact pressure takes place through a ring piece 7, which in the working position by a Screw 8 is secured on the tube 6. The edge turns 4 of the film 1 are also crimped to the inside, as can be seen from Fig.2, and against the Nickel mandrel 6 insulated by an insulating tube 9 pushed onto the same, which is on this side protruding above the nickel. The whole wrap sits in a> curved cup Contact sheet 10, the bases 11 of which are also in highly effective thermal contact with the beaded edge turns 4 stands. The bottom 11 is cooled by a Cooling coil 12, which in direct heat exchange on the outside of the floor 11, which can be perforated, with rubbing pressure. The isolation of 10 from 6 takes place through the insulating tube 9.
Der Anschluß des Kondensators erfolgt seinerseits iber den Wickeldorn 6, andererseits über einen Konaktring 13 des Bleches 10. Der so armierte Konden-,atorwickel ist mit dem an dem einen Ende vor-@tehenden Wickeldorn 6 durch die Bohrung eines -laltebleches 14 gesteckt. Zwischen diesem und einer .solierplatte 15 befindet sich eine Druckfeder 16, die )eim Anziehen einer auf dem freien Ende des Bornes 6 sitzenden Mutter 17 den eingestellten Anangsdruckwert für die Kontaktierung aufrechterhält.The capacitor is connected via the winding mandrel 6, on the other hand via a contact ring 13 of the metal sheet 10. The so reinforced condenser, ator winding is with the at one end projecting mandrel 6 through the bore of a -laltebleches 14 inserted. Between this and a .solierplatte 15 is located a compression spring 16, which is seated on the free end of the spring 6 when it is tightened Nut 17 maintains the set initial pressure value for contacting.
Als Durchflußkühlmittel für den Dorn 6 und, durch Ine isolierende Zwischenleitung getrennt, für die Cühlschlange 12 dient vorzugsweise Wasser.As a flow-through coolant for the mandrel 6 and, insulating by Ine Separate intermediate line, water is preferably used for cooling coil 12.
