Description

Das Hauptpatent enthält u. a. eine Anordnung, bei der zur Regelung der Drehzahl von Induktionsmaschinen eine läufererregte Kommutatorhintermaschine vorgesehen ist, die mit einer besonderen asynchronen Belastungsmaschine 3 (Abb. 4) gekuppelt ist. Für die Erregung der Kommutatorhintermaschine ist eine mit der Induktionsmaschine gekuppelte Drehstromerregermaschine 9 vorgesehen, deren Schlupffrequenz führende Erregerwicklung an den Kommutator eines Frequenzwandlers 10 angeschlossen ist. Dieser Frequenzwandler ist mit der Kommutatorhintermaschine mechanisch gekuppelt, und seine Schleifringe sind an einen vom Netz gespeisten Transformator τι angeschlossen.The main patent contains, inter alia. an arrangement in which to regulate the speed of Induction machines a rotor-excited commutator rear machine is provided with a special asynchronous loading machine 3 (Fig. 4) is coupled. For the excitement the commutator rear machine is provided with a three-phase exciter 9 coupled to the induction machine Excitation winding carrying slip frequency to the commutator of a frequency converter 10 connected. This frequency converter is mechanical with the commutator back machine coupled, and its slip rings are connected to a mains-fed transformer τι.

Die vorliegende Erfindung betrifft eine Vereinfachung dieser Schaltung, die namentlich dann zweckmäßig ist, wenn der Drehzahlregelbereich der Hauptindüktionsmaschine verhältnismäßig gering ist. Erfindungsgemäß ist die Schlupffrequenz führende Erregerwicklung der Drehstromerregermaschine an die Sekundärspannung der asynchronen Belastungsmaschine angeschlossen, wobei in den Sekundärstromkreis dieser Belastungsmaschine Ohmsche Widerstände oder ein eigenerregter Phasenschieber eingeschaltet ist. Der Spannungsabfall in diesen Ohmschen Widerständen bzw. die Spannung dieses eigenerregten Phasenschiebers reicht dann aus, um die Drehstromerregermaschine mit einer genügenden Erregerspannung zu versorgen. Die Größe des Erregerstromes in dieser Dreh-Stromerregermaschine kann durch die bereits vorhandenen oder durch besondere regelbare Widerstände gesteuert werden. Man erspart also bei der neuen Anordnung den Frequenzwandler 10 und den vorgeschalteten Regeltransformator 11 des Hauptpatents. The present invention relates to a simplification of this circuit, namely It is then expedient if the speed control range of the main induction machine is proportionate is low. According to the invention, the slip frequency leading excitation winding of the three-phase exciter is to the Secondary voltage of the asynchronous load machine connected, with ohmic resistances or a self-excited phase shifter being switched into the secondary circuit of this load machine. Of the Voltage drop in these ohmic resistances or the voltage of this self-excited The phase shifter is then sufficient to provide the three-phase exciter with a sufficient To supply excitation voltage. The size of the excitation current in this rotary current exciter can be controlled by the existing or by special adjustable resistors. One spares So in the new arrangement the frequency converter 10 and the upstream control transformer 11 of the main patent.

Die Zeichnung veranschaulicht die neue Schaltung. Ebenso wie bei Abb. 4 des Hauptpatents ist ι die Induktionsmaschine, in deren Sekundärstromkreis die Kommutatorhintermaschine 2 eingeschaltet ist. Diese ist mit einem Asynchronmotor 3 als Belastungsmaschine gekuppelt. 9 ist die mit der Maschine 1 gekuppelte Drehstromerregermaschine, deren Schlupffrequenz führender Erregerkreis an die regelbaren Ohmschen Widerstände 10 angeschlossen ist. Die Ohmschen Widerstände liegen im Sekundärstromkreis der Maschines.The drawing illustrates the new circuit. As with Fig. 4 of the main patent is ι the induction machine, in whose secondary circuit the commutator rear machine 2 is switched on. This is with an asynchronous motor 3 as the loading machine coupled. 9 is the three-phase exciter coupled to the machine 1, whose The excitation circuit leading the slip frequency is connected to the controllable ohmic resistors 10 is. The ohmic resistances are in the secondary circuit of the machines.
