PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren zur Geschwindigkeitsregelung bezw. zum Anlassen von kompensierten Wechselstrom-Kollektormaschinen , besonders von Serienmotoren, welches eine Änderung des Erregerstromes behufs Geschwindigkeitsregelung in weiten Grenzen gestattet, ohne daß eine Unterbrechung des Hauptstromkreises erforderlich ist. Gemäß der Erfindung ist nämlich einThe invention relates to a method for speed control BEZW. for starting of compensated AC collector machines, especially of series motors, which a change of the excitation current for speed control in wide Limits permitted without interrupting the main circuit is. According to the invention is namely a
ίο Teil des in der einen Schaltung den Erreger-Strom liefernden Serientransformators in der anderen Schaltung als Drosselspule vor die Erregerbürsten geschaltet.ίο Part of the excitation current in one circuit supplying series transformer in the other circuit as a choke coil in front of the Exciter brushes switched.
In der Zeichnung sind als Ausführungsbeispiele zwei Schaltungen angegeben, welche die neue Einrichtung zeigen, und zwar zeigt Fig. ι einen Fall, in welchem der Serientransformator dazu dient, um den Erregerstrom zu verstärken, Fig. 2 einen Fall, in dem der Serientransformator den Erregerstrom verkleinert.In the drawing, two circuits are indicated as exemplary embodiments, which show the new device, namely Fig. ι shows a case in which the series transformer serves to amplify the excitation current, FIG. 2 shows a case in which the series transformer reduces the excitation current.
Ist bei der Schaltung nach Fig. 1 der Schalter c geschlossen, so liegt der Transformator t u in Serienschaltung mit der Ständerwicklung s am Netz und sekundär (mittels des Wicklungsteiles u) an den Erregerbürsten b b. Bei geöffnetem Schalter c ist der Wicklungsteil u abgeschaltet, während der Wicklungsteil t in Reihe mit der Ständerwicklung s und den Erregerbürsten b bleibt und als Drosselspule wirkend den Erregerstrom, der in dieser Schaltung gleichzeitig auch der Hauptstrom ist, verringert. Wie die Zeichnung zeigt, wird in keiner Stellung des Schalters c der Hauptstromkreis unterbrochen. If the switch c is closed in the circuit according to FIG. 1, the transformer tu is connected in series with the stator winding s to the network and secondarily (by means of the winding part u) to the exciter brushes b b. When the switch c is open, the winding part u is switched off, while the winding part t remains in series with the stator winding s and the excitation brushes b and, acting as a choke coil, reduces the excitation current, which is also the main current in this circuit. As the drawing shows, the main circuit is not interrupted in any position of switch c.
Bei der Schaltung nach Fig. 2 dient bei geschlossenem Schalter c die Wicklung t des Transformators als Primärteil, die Teile t und u zusammen als Sekundärteil, und bei geöffnetem Schalter c und abgeschalteter Wicklung if die Wicklung u als Drosselspule.In the circuit according to FIG. 2, when the switch c is closed, the winding t of the transformer serves as the primary part, the parts t and u together as the secondary part, and when the switch c is open and the winding if is switched off, the winding u is used as a choke coil.
Der Transformator tu ist als Einspulentransformator gezeichnet, es steht natürlich nichts im Wege, ihn als Zweispulentransformator auszuführen,- Unter Umständen kann es vorteilhaft sein, den Schalter c durch einen Zentrifugalapparat, ein Zeitrelais oder dergl. zu beeinflussen.The transformer tu is drawn as a single-coil transformer, of course nothing stands in the way of implementing it as a two-coil transformer - it may be advantageous to use a centrifugal device, a time relay or the like to influence switch c.
