Gegenstand vorliegender Erfindung ist eineThe present invention is a
Vorrichtung zur statischen Transformierung von dreiphasigen sinusförmigen oder annähernd sinusförmigen Wechselströmen in einphasige Wechselströme mit dreifacher Frequenz.Device for static transformation of three-phase sinusoidal or approximately sinusoidal alternating currents into single-phase alternating currents with three times the frequency.
Die Fig. 1 und 2 zeigen zwei Ausführungsformen der Vorrichtung, die Fig. 3 ein Diagramm des der Erfindung zugrunde liegenden Prinzips.FIGS. 1 and 2 show two embodiments of the device, and FIG. 3 shows a diagram of the principle underlying the invention.
Gemäß Fig. 1 wird der angestrebte Zweck erreicht, dadurch, daß man die sekundären Spulen dreier einphasiger Transformatoren mit stark gesättigtem Eisenkern in Serie schaltet, wobei jeder Eisenkern eine primäre Wicklung *5 besitzt, deren jede an eine Phase des dreiphasigen Systems angeschlossen ist. Die primären Spulen können in Stern oder Dreieck geschaltet sein.According to Fig. 1, the intended purpose is achieved by having the secondary Switches coils of three single-phase transformers with a heavily saturated iron core in series, each iron core has a primary winding * 5, each of which is connected to one phase of the three-phase System is connected. The primary coils can be connected in star or delta.
Gemäß Fig. 2 werden die einzelnen Transformatoren vereinigt zu einem einheitlichen Transformator mit stark gesättigtem Eisenkern. Die Kerne α, b, c dieses Transformators sind bestimmt für die drei Phasen der dreiphasigen primären Spulen, während der vierte Kern d für die einphasige sekundäre Spule mit dreifacher Frequenz vorgesehen ist. Man kann dasselbe Resultat erhalten, wenn man die in diesem Fall in Serie geschalteten sekundären Spulen über den primären Spulen auf denselben Eisenkernen anordnet, wobei dann der vierte Kern nur zum Schließen der magnetischen Stromkreise dient.According to FIG. 2, the individual transformers are combined to form a uniform transformer with a highly saturated iron core. The cores α, b, c of this transformer are intended for the three phases of the three-phase primary coils, while the fourth core d is intended for the single-phase secondary coil with three times the frequency. The same result can be obtained if the secondary coils, connected in series in this case, are arranged above the primary coils on the same iron cores, the fourth core then only being used to close the magnetic circuits.
Wie Fig. 3 zeigt, ist das Prinzip auf welchem die Erfindung sich begründet, folgendes :As Fig. 3 shows, the principle on which the invention is based is as follows:
Die Summe dreier sinusförmiger oder annähernd sinusförmiger Wechselströme, die unter sich um 120° versetzt sind und auf magnetisch stark gesättigte Eisenkerne wirken, welche die in geeigneter Weise in Serie geschalteten Sekundärwicklungen tragen, ergeben infolge der durch die Eisensättigung bewirkten starken Abflachung der einzelnen Stromkurven einen einphasigen Strom mit dreifacher Frequenz.The sum of three sinusoidal or approximately sinusoidal alternating currents that are below are offset by 120 ° and act on magnetically strongly saturated iron cores, which the suitably carry secondary windings connected in series, result from the the iron saturation caused a strong flattening of the individual current curves single-phase current with triple frequency.
