Description
In Hochspannungsnetzen großer Leistung finden in letzter Zeit Zweiwicklungsgeneratoren Anwendung, welche so geschaltet sind, daß je eine Hälfte des Generators auf ein Netz geschaltet wird. Die Netze können auf diese Weise über die Generatoren gekuppelt werden, wobei die Kurzschlußleistung der einzelnen Netze verkleinert wird. Zur weitgehenden Trennung einzelner Netzteile voneinander ist es zweckmäßig, die Streuung zwischen den einzelnen Wicklungen des Zweiwicklungsgenerators möglichst zu erhöhen. Die Wicklungen werden bisher zu diesem Zweck in getrennten Nuten eingebettet, welche einzeln oder gruppenweise abwechselnd am Ständerumfang angeordnet sind. Diese Anordnungen haben jedoch den Nachteil, daß magnetische Unsymmetrien bei unsymmetrischer Belastung der Maschine auftreten. Bei Verlegung der beiden Wicklungen in einer gemeinsamen Nut mit rechteckigem Querschnitt erhält man eine ungenügende induktive Trennung zwischen beiden Wicklungen.-Gemäß der Erfindung werden diese Mängel dadurch beseitigt, daß zwischen solchen Spulen-Seiten in einer Nut, die verschiedenen Wicklungen angehören, der Nutenquerschnitt durch Vorsprünge am aktiven Eisen verengt ist. Hierdurch wird die magnetische Streuung für jede Spulenseite vergrößert und eine induktive Trennung der Wicklungen erzielt, deren Maß von den Abmessungen der Querschnittsverengung abhängt.Two-winding generators have recently been found in high-voltage networks of great power Application which are connected in such a way that one half of the generator is connected to a network will. The networks can be coupled in this way via the generators, with the short-circuit power of each Networks is reduced in size. It is necessary for the extensive separation of individual power supply units from one another expedient, the scatter between the individual windings of the two-winding generator to increase if possible. The windings are so far in separate slots for this purpose embedded, which are arranged individually or in groups alternately on the stand circumference are. However, these arrangements have the disadvantage that magnetic asymmetries asymmetrical loading of the machine. When laying the two windings In a common groove with a rectangular cross-section, an insufficient inductive is obtained Separation between both windings.-According to the invention, these shortcomings are eliminated this eliminates the fact that between such coil sides in a slot, the different windings belong, the groove cross-section is narrowed by projections on the active iron. This will reduce the magnetic scattering for each coil side enlarged and an inductive separation of the windings achieved, their dimension depends on the dimensions of the cross-sectional constriction.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch an einem Zweiwicklungsgenerator dargestellt. Die die beiden Wicklungen α und b aufnehmende Nut im Ständereisen ist so gestanzt, daß sie Vorsprünge c, d besitzt, die zwischen die Wicklungen ragen und den Nutenquerschnitt verringern. Durch die Stege c, d wird eine Verkettung der Streuflüsse der beiden Wicklungen verringert.In the drawing, an embodiment of the invention is shown schematically on a two-winding generator. The groove in the stator iron which accommodates the two windings α and b is stamped in such a way that it has projections c, d which protrude between the windings and reduce the cross-section of the groove. The webs c, d reduce the linkage of the leakage fluxes of the two windings.
