Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

In der Beschreibung des Hauptpatentes ist erwähnt, daß die Stabilisierung elektrischer Maschinen dadurch erzielt werden kann, daß einzelne Polpaare teilweise gegeneinander geschaltet werden. Versuche haben ergeben, daß diese Art der Reglung einer weitgehenden Verwendung fähig ist.In the description of the main patent it is mentioned that the stabilization is electrical Machines can be achieved in that individual pole pairs are partially switched against one another will. Tests have shown that this type of regulation is capable of widespread use.

Man kann beispielsweise bei einer selbsterregten Maschine in niedrigen Spannüngsbereichen die Feldspulen gegeneinander schalten und eine Reglung von der Spannung Null an dadurch erzielen, daß man parallel zu der einen Gruppe von Feldspulen einen veränderlichen Widerstand schaltet. Bei entsprechender Größe dieses parallel geschalteten Widerstandes wird fast der gesamte Strom durch die gegeneinander geschalteten Feldwicklungen fließen, und die Maschine als Generator geringe Spannung erzeugen, wobei sie trotz der Selbsterregung vollständig stabil ist. Bei allmählichem Kurzschließen des Parallelwiderstandes wird die Wirkung der einander entgegengeschalteten Pole geschwächt, und die Spannung steigt an. Ist der Parallelwiderstand vollständig kurzgeschlossen, so werden die bisher einander entgegengeschalteten Magnetwicklungen in Reihe geschaltet. Die weitere Reglung erfolgt dann durch allmähliche Vergrößerung und schließliche Öffnung des Parallelwiderstandes. One can, for example, with a self-excited machine in low voltage ranges switch the field coils against each other and achieve a regulation from the voltage zero by that one parallel to the a group of field coils switches a variable resistor. With the appropriate The size of this resistor connected in parallel is almost the entire current through it the opposing field windings flow, and the machine as a generator is low Generate tension, being completely stable in spite of the self-excitation. With gradual Short-circuiting the parallel resistance will have the effect of opposing each other Poles weaken and the tension rises. Is the parallel resistance complete short-circuited, the magnetic windings that were previously connected in opposition to one another are short-circuited connected in series. The further regulation then takes place by gradual enlargement and finally opening of the parallel resistor.

Die Zeichnung zeigt ein Ausführungsbeispiel. Es bezeichnen α den Anker eines Generators, b und c einander entgegengeschaltete Teile der Feldwicklung, d einen Umschalter und e einen regelbaren Widerstand, der parallel zu dem umschaltbaren Teil c der Feldwicklung gelegt wird.The drawing shows an embodiment. Α denotes the armature of a generator, b and c oppositely connected parts of the field winding, d a changeover switch and e a controllable resistor which is placed in parallel with the switchable part c of the field winding.
