Description

Die Erfindung betrifft die Erregung von selbsterregten Wechselstromgeneratoren, bei denen neben einer über einen Umformersatz arbeitenden Haupterregung ein mit dem Generator umlaufender Wechselstromdauc rmagnetgenerator zur Hilfserregung vorgesehen ist, der über einen Umformersatz auf die Erregerwicklung des Hauptgenerators wirkt. Nach der Erfindung wird eine derartige Einrichtung dadurch vorteilhaft ausgestaltet, daß der letztgenannte Umformersatz nicht nur die Erregung des Hauptgenerators einleitet, sondern auch den Generator des Umformersatzes für die Haupterregung erregt. Die Haupterregung setzt daher sofort beim Anlaufen des Motors -des Umformersatzes für die Haupterregung kräftig ein. Der Hauptgenerator wird also in sehr1:urzer Zeit stark erregt.The invention relates to the excitation of self-excited alternating current generators, in which in addition to a main excitation working via a transformer replacement Alternating current permanent magnet generator rotating around the generator is provided for auxiliary excitation which acts on the excitation winding of the main generator via a transformer replacement. According to the invention, such a device is advantageously designed in that that the last-mentioned converter replacement not only initiates the excitation of the main generator, but also energizes the generator of the converter set for the main excitation. the The main excitation therefore sets in immediately when the motor starts up - the converter set for the main excitation vigorously. So the main generator will be in a very short time very excited.

In den Fig. i und 2 der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Der selbsterregte Wechselstromgenerator i besitzt eine über einen Umformersatz 12, 11 arbeitende Haupterregung und gleichzeitig einen mit ihm unmittelbar oder über Getriebe gekuppelten Wechselstromdauerma.gnetgeneratOr 5 zur Hilfserregung. Der Generator 5, wirkt hierbei ebenfalls über einen aus einem Motor 17 und einem Generator 16 bestehenden Umformersatz auf die Erregerwicklung 2 des Hauptgenerators. Der Haupterregergenerator i i und der Hilfserregergenerator 16 sind bei der in Fig. i dargestellten Anordnung hintereinander-, bei der in Fig.2 gezeigten Anordnung parallel zueinander geschaltet. Die Hilfserregermaschine 16 erregt in beiden Fällen außer sich selbst zugleich auch noch die Erregerwicklung ig der Haupterregermaschine i i. Das. hat für die Ausführung nach Fig. 2 den Vorteil. daß bei Beginn des Erregungsvorganges die Haupterregermaschine i i als Motor anläuft und damit den Motor 12 beim Anlauf unterstützt. Erst wenn bei höherer Generatorspannung der Motor 12; weiter hochläuft, arbeitet die Haupterregermaschine i i wieder als Generator und speist die Erregerwicklung 2 des Generators i. Durch Öffnen des Schalters io der Fig. 2 wird dann die Hilfserregermaschine 16 von dem Stromkreis der Erregerwicklung 2 abgeschaltet, so daß sie nur mehr die Erregerwicklung i8 der Haupterregermaschine i i speist.In Figs. I and 2 of the drawing, embodiments of the invention are shown. The self-excited alternating current generator i has a main excitation operating via a transformer set 12, 11 and at the same time an alternating current permanent magnet generator 5 coupled to it directly or via a gearbox for auxiliary excitation. The generator 5 here also acts on the excitation winding 2 of the main generator via a transformer set consisting of a motor 17 and a generator 16. The main exciter generator ii and the auxiliary exciter generator 16 are connected one behind the other in the arrangement shown in FIG. 1 and parallel to one another in the arrangement shown in FIG. The auxiliary exciter 16 excites in both cases not only itself but also the exciter winding ig of the main exciter i i. That. has the advantage for the embodiment according to FIG. that at the beginning of the excitation process the main exciter ii starts up as a motor and thus supports the motor 12 during start-up. Only when the motor 12; continues to run up, the main exciter ii works again as a generator and feeds the excitation winding 2 of the generator i. By opening the switch io of FIG. 2, the auxiliary exciter 16 is then disconnected from the circuit of the exciter winding 2, so that it only feeds the exciter winding i8 of the main exciter ii.
