Description
Anordnung zur Regelung von einphasig gespeisten Asynchronmaschinen mittels an die Rotorkreise angeschlossener Hintermaschinen, die an Stromkreise mit ausgeprägten Oberschwingungen angeschlossen sind. Man kann Asynchronmaschinen mit ausgeprägten Oberschwingungen am Sekundärkreis dadurch regeln, daß man an den Rotorkreis eine Hintermaschine anschließt, deren Ständer mit einer Kompensationswicklung versehen ist und deren Erregung von einer fremden Stromquelle aus erfolgt. Handelt es sich um die Regelung von Einphaseninduktionsmaschinen, so ergibt sich eine wesentliche Vereinfachung, indem man die an den Rotorkreis mehrphasig angeschlossene Hintermaschine einphasig vom Netz aus erregt und zur Erzeugung des Drehfeldes im Ständer der Kollektorhintermaschine eine kurzgeschlossene Wicklung anordnet.Arrangement for the regulation of single-phase fed asynchronous machines by means of rear machines connected to the rotor circuits, which are connected to electrical circuits with pronounced harmonics are connected. You can use asynchronous machines Regulate pronounced harmonics on the secondary circuit by switching to the rotor circuit a rear machine is connected, the stator of which is provided with a compensation winding and whose excitation comes from an external power source. Is it To regulate single-phase induction machines, there is an essential one Simplification by removing the rear machine connected to the rotor circuit in multiple phases Single-phase excited from the mains and to generate the rotating field in the stator of the collector rear machine arranges a short-circuited winding.
Ein Ausführungsbeispiel der Erfindung ist in Abb. i veranschaulicht. a bedeutet das Einphasennetz, an dem die Wechselstrominduktionsmaschine b liegt. An den Rotorkreis der Induktionsmaschine ist über die Schleifringe c die Kollektorhintermaschine d angeschlossen. Die Kollektorhintermaschine ist mit einer Kompensationswicklung e versehen und wird vom Rotor aus gegebenenfalls aus dem Transformator f über die Schleifringe g einphasig erregt. Die Kompensationswicklung ist an den Kollektor lt angeschlossen.An embodiment of the invention is illustrated in Figure i. a means the single-phase network to which the AC induction machine b is connected. The collector rear machine is connected to the rotor circuit of the induction machine via slip rings c d connected. The collector rear machine is with a compensation winding e and is supplied from the rotor, if necessary, from the transformer f via the Slip rings excited in single phase. The compensation winding is on the collector connected according to
Gemäß der Erfindung ist nunmehr außer der Wicklung e eine Käfigwicklung 1 vorgesehen, welche die Erzeugung des Drehfeldes 'im Ständer der Kollektormaschine ermöglicht. Die Wirkung der Käfigwicklung könnte auch dadurch erxeicht werden, daß, wie in Abb. 2 veranschaulicht, die Ständerwicklung der Kollektormaschine über einen Widerstand kurzgeschlossen wird, der so beschaffen ist, daß der Schlupfstrom der Induktionsmaschine noch durch die Kompensationswicklung hindurchgeht.According to the invention, a cage winding 1 is now provided in addition to the winding e , which enables the generation of the rotating field in the stator of the collector machine. The effect of the squirrel cage winding could also be achieved in that, as illustrated in Fig. 2, the stator winding of the collector machine is short-circuited via a resistor which is such that the slip current of the induction machine still passes through the compensation winding.
Die Abb. i und 2 zeigen Beispiele mit Läufererregung der Kollektormaschine. An Stelle der Läufererregung könnte auch Ständer,-erregung der Kollektormaschine treten. Man wird dann im Läufer vorzugsweise eine Käfigwicklung anordnen.Figs. I and 2 show examples with rotor excitation of the collector machine. Instead of the rotor excitation, the stator excitation of the collector machine could also be used step. A cage winding will then preferably be arranged in the rotor.
