Description

Umlaufender Feldmagnet für Turbogeneratoren, bei dem die Erregerwicklung aus mehr als zwei aus blanken Metallbändern gewickelten Spulen besteht. Bei dem im Hauptpatent beschriebenen umlaufenden Feldmagneten kommt es darauf an, daß die aus blanken Metallbändern gewickelten Erregerspulen an dem einen Ende derart parallel geschaltet und an gemeinsame Stromzuleitungen angeschlossen sind, daß die anderen Enden sämtlicher Spulen unmittelbar an dem Eisenkörper des Feldmagneten anliegen können, um hierdurch eine wirksamere Kühlung zu erzielen. Bei der in dem Hauptpatent angegebenen Anordnung kann also nur die eine der beiden äußersten Windungen der Wicklung in metallischer Berührung mit dem Eisenkörper stehen.Circulating field magnet for turbo generators, in which the excitation winding consists of more than two coils wound from bare metal strips. In which In the main patent described rotating field magnet, it is important that the Excitation coils wound from bare metal strips at one end in such a parallel manner switched and connected to common power supply lines that the other Ends of all coils are in direct contact with the iron body of the field magnet in order to achieve a more effective cooling. In the The arrangement specified in the main patent can only be one of the two outermost ones Turns of the winding are in metallic contact with the iron body.

Gemäß der Erfindung ist dagegen die Wicklung in einer jeden Nut in radialer Richtung in zwei entgegengesetzt gewickelte Teile unterteilt, und die beiden Wicklungsteile sind mit ihren in der Mitte der Nut liegenden Enden an die Stromzuleitungen angeschlossen, während die sowohl dem Boden der Nut als die dem Umfange des Läufers zugekehrten beiden äußersten Windungen den Körper des Läufers metallisch berühren.According to the invention, however, the winding in each slot is in radial direction divided into two oppositely wound parts, and the two Winding parts are connected to the power supply lines with their ends in the middle of the slot connected, while both the bottom of the groove and the circumference of the runner the two outermost turns facing the body of the runner metallically touch.

In der Zeichnung zeigt Abb. i eine Nut mit den Wicklungen im Querschnitt und Abb. z das Schaltungsschema des neuen Feldmagneten.In the drawing, Fig. I shows a groove with the windings in cross section and Fig. z shows the circuit diagram of the new field magnet.

Die in der Nut eingelegte Wicklung ist in radialer Richtung in zwei Teile a und b unterteilt, welche durch eine Isolation c getrennt und derart gewickelt sind, daß die Wicklungsrichtung des dem Boden der Nut zugekehrten Wicklungsteiles b derjenigen des dem Umfang des Läuferkörpers, d. h. der öffnung der Nut zugekehrten Wicklungsteiles a entgegengesetzt ist. Die beiden Wicklungsteile a und b sind an ihren in der Nut liegenden Enden x parallel geschaltet und an die je für die Hälfte der Teile a und b gemeinsame Stromzuleitunge oder! f angeschlossen. Infolgedessen können sowohl die dem Boden der Nut als die der Öffnung zugekehrten äußersten Windungen yi und y2 in metallischer Berührung mit dem Eisenkörper des Läufers oder dem metallischen Nutenkeil stehen. Die Abführung der Wärme an den Eisenkörper des Läufers ist durch diese Anordnung in noch höherem Maße begünstigt als bei der im Hauptpatent angegebenen Anordnung.The winding inserted in the slot is divided in the radial direction into two parts a and b, which are separated by insulation c and wound in such a way that the winding direction of the winding part b facing the bottom of the slot is that of the circumference of the rotor body, ie the opening the groove facing winding part a is opposite. The two winding portions a and b are connected in parallel at their x lying in the groove ends and the each for half of the parts a and b common power Zuleitunge or! f connected. As a result, both the outermost windings yi and y2 facing the opening can be in metallic contact with the iron body of the rotor or the metallic slot wedge. The dissipation of heat to the iron body of the rotor is promoted by this arrangement to an even greater extent than in the case of the arrangement specified in the main patent.
