Description

Die Dämpferwicklung für Läufer von Turbogeneratoren bringt man häufig in den gleichen Nuten unter wie die Hauptwicklung. Es ist nun vorgeschlagen worden, solche Dämpferwicklungen aus voneinander unabhängigen, in sich geschlossenen Einzelwindungen oder Windungsgruppen zu bilden. Wenn bei dieser Bauart die Windungen blank aufeinanderliegen, dann wirken ihre Stirnverbindungen als Kurzschlußring, zumal sie ja auch durch die Fliehkraft stark aufeinander und gegen die unisolierte Wicklungskappe gepreßt werden. In diesem Falle ist es also ganz unwichtig, daß die einzelnen Windungen oder Windungsgruppen der Dämpferwicklung in sich geschlossen sind; denn der Kontakt zwischen den Windungshälften oder, wie man auch sagen kann, Spulenseiten ist auf alle Fälle gewährleistet, besonders wenn man die aufeinanderliegenden Stirnverbindungen der Dämpferwicklung, wie ebenfalls bereits vorgeschlagen, noch versilbert.The damper winding for rotors of turbo generators is often brought into the same grooves underneath as the main winding. It has now been suggested such Damper windings made up of independent, self-contained individual windings or to form groups of turns. If the turns are bare on top of each other in this design, then their end connections are effective as a short-circuit ring, especially since they are strongly pressed against each other and against the uninsulated winding cap by centrifugal force will. In this case it is completely unimportant that the individual turns or groups of turns of the damper winding are self-contained; because the contact between the turn halves or how to can also say that the coil side is guaranteed in any case, especially if you have the superimposed end connections of the damper winding, as also already proposed, still silver-plated.

Nach der Erfindung besteht daher die Dämpferwicklung aus einzelnen Spulenseiten, also aus entsprechend dem Wickelschritt der Dämpfungsspule abgebogenen Stäben. Es ist einleuchtend, daß hierdurch die Herstellung der Dämpferwicklung wesentlich erleichtert wird.According to the invention, therefore, the damper winding consists of individual coil sides, that is, from bars bent in accordance with the winding step of the damping coil. It is Obviously, this makes the manufacture of the damper winding much easier will.

In der Zeichnung sind zwei Ausführungsbeispiele für die Erfindung in der Abwicklung dargestellt. Gemäß Fig. 1 ist die untere Lage« der Stirnverbindungen der Dämpferwicklungsstäbe nach links, die obere Lage ο nach rechts abgebogen, während gemäß Fig. 2 die untere Lage α gerade durchgeführt und nur die obere Lage ο abgebogen ist. Besteht die Dämpferwicklung je Nut aus mehr als zwei übereinanderliegenden Teilstäben, so kann man die Stäbe der Wickelköpfe abwechselnd nach links und rechts umbiegen bzw. die eine Lage umbiegen und die andere gerade weiterführen. In der Zeichnung bedeutet e die Abwicklung des Läufereisens und k diejenige der Wickelkappe, längs der die Enden der Stäbe gerade abgeschnitten sind.In the drawing, two exemplary embodiments of the invention are shown in the process. According to FIG. 1, the lower layer of the end connections of the damper winding bars is bent to the left, the upper layer ο bent to the right, while according to FIG. 2 the lower layer α is straight through and only the upper layer ο is bent. If the damper winding consists of more than two superimposed partial rods per groove, the rods of the winding heads can be bent alternately to the left and right or one layer can be bent over and the other straight ahead. In the drawing, e denotes the development of the rotor iron and k denotes that of the winding cap along which the ends of the rods have just been cut off.
