Description
Elektrischer Kondensator hoher Kapazität, dessen durch Isolationsschichten getrennte, bandförmige, an beiden Stirnseiten über den Wickelkörper herausragende Belegungen auf einem flanschlosen, an beiden Enden offenen Rohr aufgewickelt sind Im Kondensatorenbau hat man bei Ausführungen, bei welchen die zwei Belegungen durch das Dielektrikum getrennt aufeinandergewickelt werden, als Kern der so gebildeten Spule ein Rohr verwendet. Letzteres war größtenteils aus Isoliermaterial angefertigt. Gegenüber einem vollen Kern hatte das Rohr lediglich den Vorteil eines geringeren Gewichtes. -Es hat sich nun gezeigt, daß bei den namentlich für die Erhöhung des Leistungsfaktors von elektrischen Maschinen verwendeten Kondensatoren die Selbsterwärmung eine gewisse Rolle spielt. Zwecks Abkühlung werden die Kondensatoren daher in ein Ölbad ge- taucht; jedoch mußte die Flüssigkeit mechanisch bewegt wenden, wollte man wirklich eine Abkühlung erreichen. - Die Bewegung der Kühlflüssigkeit kann jedoch auch durch Wärmekonvektion erzeugt werden, wenn man das zentrale Rohr aus Metall herstellt. Bei den bekannten Kondensatoren dieser Bauart müssen jedoch für die elektrischen Anschlüsse der Belegungen besondere Vorrichtungen vorgesehen werden. Die Herstellung der Anschlüsse durch Aufpressen von Anschlußscheiben auf die überstehenden Belegungsränder des Wickels, wie sie bei Kondensatoren mit hohlem Kern aus Isoliermaterial angewendet worden ist, ist hierbei nicht möglich. . Gegenstand vorliegender Erfindung ist ein elektrischer Kondensator von hoher Kapazität, bei welchem der an sich bekannte hohle Kern derart gebildet ist, daß er sich einmal vorzüglich zur Abkühlung des Kon.densatorwickels und außerdem auch als Anschlußorgan für die Belegungen eignet. Zu .diesem Zweck ist erfindungsgemäß der als Rohr dienende Kern aus zwei tief in den Wickel hineinragenden Metallrohrstücken und aus einem Rohrstück aus Isoliermaterial, das die beiden Metallrohrstücke voneinander trennt, zusammengesetzt.Electrical capacitor of high capacitance, the band-shaped coverings of which are separated by insulating layers and protruding from the winding body on both ends are wound on a flangeless tube open at both ends. a tube is used as the core of the coil formed in this way. The latter was mostly made of insulating material. Compared to a full core, the tube only had the advantage of being lower in weight. It has now been shown that self-heating plays a certain role in the capacitors used, in particular, to increase the power factor of electrical machines. For the purpose of cooling the capacitors are therefore immersed in an oil bath overall; however, the liquid had to be turned in a mechanically agitated manner if one really wanted to achieve cooling. - The movement of the cooling liquid can, however, also be generated by thermal convection if the central tube is made of metal. In the known capacitors of this type, however, special devices must be provided for the electrical connections of the assignments. It is not possible to produce the connections by pressing connection disks onto the protruding covering edges of the winding, as has been used in the case of capacitors with a hollow core made of insulating material. . The present invention relates to an electrical capacitor of high capacitance, in which the hollow core known per se is formed in such a way that it is ideally suited for cooling the Kon.densatorwickels and also as a connecting element for the assignments. For this purpose, according to the invention, the core serving as a tube is composed of two pieces of metal tube protruding deep into the coil and of a piece of tube made of insulating material that separates the two pieces of metal tube from one another.
Diese metallenen Rohrstücke ragen beidseitig aus denn Wickel heraus und können daher als Klemmen für den Apparat dienen. Die Anschlußscheiben liegen in bekannter Weise vermittels , Armen auf dem Rand der Belegungen auf und sind so eng mit jedem Teil der letzteren verbunden. Durch Thermosiphonwirkung wird eine Ölzirkulation im Innern des Wickels erzeugt und so ohne jeg- liche mechanische Mittel für vermehrte Ab- kühlung des Kondensators gesorgt.These metal pipe pieces protrude from the coil on both sides and can therefore serve as clamps for the apparatus. The connecting disks rest in a known manner by means of arms on the edge of the coverings and are thus closely connected to each part of the latter. An oil circulation is produced in the interior of the package and thus without Any such mechanical means for increased waste of the condenser cooling provided by thermosiphon.
Beiliegende Zeichnung zeigt einen elektrischen Kondensator hoher Kapazität gemäß der Erfindung.The accompanying drawing shows a large capacitance electric capacitor according to the invention.
Abb. i ist eine teilweise im Schnitt gezeichnete Ansicht, Abb. a eine Einzelheit und Abb. 3 ein Grundriß. In den Abb. r bis 3 bezeichnet a ein dreiteiliges Rohr, wobei a1, a2 aus Metall und a3 aus Isoliermaterial bestehen. Der Teil a3 besteht vorzugsweise aus den Kondensationsprodukten des Formaldehyds und wird nach den beiden Metallrohrteilen geformt.Fig. I is a partially sectioned view, Fig. A is a Detail and Fig. 3 a plan. Referred to in Figs. R to 3 a is a three-part tube, with a1, a2 made of metal and a3 made of insulating material. Part a3 preferably consists of the condensation products of formaldehyde and is shaped according to the two metal pipe parts.
Die Belegungen haben Zwischenlagen von Papier und stehen an den Stirnenden des Wickels über den Wickelkörper vor. Auf jeder dieser Stirnseiten sitzt ein Kontaktstern c, dessen Arme cl radial von der Nabe c2 abstehen und Sägezähne besitzen, welche besonders aus Abb. 2a ersichtlich sind. Diese Sterne werden auf den Kern a aufgesteckt und mittels einer auf das mit Gewinde versehene Ende des Kernes aufgeschraubten Mutter an die Belegungsränder angepreßt. Die beiden metallischen Enden des hohlen Kernes bilden alsdann die Pole des Kondensators. Sie stehen in elektrischer Berührung mit allen Metallfolien der Belegungen und haben mit diesen dieselbe Temperatur, welche gewöhnlich wesentlich höher ist als die des den Kondensator umgebenden Öles. Dieses Öl wird sich im Hohlkern mehr erwärmen als außerhalb und wird dadurch eine Wärmezirkulation hervorrufen, welche um so größer ist bei senkrechter Lage des Kernes.The assignments have intermediate layers of paper and are at the front ends of the winding over the winding body. A contact star sits on each of these end faces c, whose arms cl protrude radially from the hub c2 and have saw teeth, which can be seen particularly in Fig. 2a. These stars are attached to the core a and screwed onto the threaded end of the core by means of a Nut pressed against the edges of the covering. The two metallic ends of the hollow The poles of the capacitor then form the core. They are in electrical contact with all metal foils of the coverings and have the same temperature with them, which is usually much higher than that of the oil surrounding the condenser. This oil will heat up more in the hollow core than outside and thus becomes a Causing heat circulation, which is all the greater if the core is in a vertical position.
