Description
Einrichtung zur Spannungsregelung elektrischer Umformer. Zur Erzielung einer bestimmten Abhängigkeit der von einem Umformer, beispielsweise einem Gleichrichter oder Einankerumformer, gelieferten Gleichspannung vom Belastungsstrom, kann man sich bekanntlich der sog. Schnellregler bedienen. Bei nicht zu raschen .Änderungen der Belastung erfüllen diese Apparate ihre Aufgabe befriedigend, dagegen machen sich die durch die Massenträgheit bedingten Verzögerungen in um so höherem Mäße bemerkbar, je rascher die Stromschwankungen vor sich gehen.Device for voltage regulation of electrical converters. To achieve a certain dependency of a converter, for example a rectifier or single armature converter, supplied direct voltage from the load current, can be As is well known, use the so-called fast regulator. If the changes are not too rapid These devices do their job satisfactorily, counteracting the stress The delays caused by the inertia are all the greater noticeable, the faster the current fluctuations go on.
Die Erfindung verfolgt das gleiche Ziel bei Anwendung eines an sich bekannten Zusatztransformators unter Vermeidung jeglicher mechanischer Hilfsmittel. Wie für einen Gleichrichter aus der beiliegenden Fig. i ersichtlich, befindet sich zwischen dem Transformator t und dem Gleichrichter g ein Zusatztransformator i, mit den Erregerwicklungen e, d und den Zusatzwicklungen b 'und c: Die Erregerwicklungen sind an die Sekundärwicklung des Transformators t angeschlossen, und zwar einerseits bei x und andererseits über die Kompoundierungsdrosselspule j an y. Die Kompoundierungsdrosselspule jbesitzt die wechselstromdurchflossenen Wicklungen v und w, sowie die gleichstromdurchflossenen Wicklungenu und p. Die Hauptstromwicklung u und die Nebenschlußwicklung P sind derart bemessen, daß mit zunehmender Belastung eine Sättigung im Eisenkern der Drosselspule j eintritt, wodurch die drosselnde Wirkung der Wicklungen v und w vermindert wird und die Spannung an den Wicklungen. d, e des Zusatztransformators i ansteigt. Mit ansteigender Erregerspannung nimmt auch die in den Zusatzwicklungen b und c induzierte Spannung zu und erhöht oder vermindert die dem Gleichrichter g zugeführte Wechselspannung.The invention pursues the same goal when using an additional transformer known per se while avoiding any mechanical aids. As can be seen for a rectifier from the accompanying FIG on the one hand at x and on the other hand via the compounding reactor j to y. The compounding reactor j has the alternating current-carrying windings v and w, as well as the direct-current carrying windings u and p. The main current winding u and the shunt winding P are dimensioned in such a way that, with increasing load, saturation occurs in the iron core of the choke coil j, whereby the choking effect of the windings v and w is reduced and the voltage on the windings is reduced. d, e of the additional transformer i increases. As the excitation voltage increases, the voltage induced in the additional windings b and c also increases and increases or decreases the alternating voltage supplied to the rectifier g.
Durch passende Wahl der Größenverhältnisse kann ein jeder beliebige Verlauf der vom Umformer g gelieferten Gleichspannung erzielt werden. Es ist somit eine abfallende, eine konstante, oder eine ansteigende Spannungscharakteristik einsteLban Der Widerstand v in Reihe mit der Nebenschlußwicklung P gestattet je nach Bedarf eine Verschiebung des Sättigungspunktes des Eisenkernes j, im gewünschten Sinne. Die gleiche Wirkung läßt sich auch erzielen durch Anwendung eines Nebenschlusses zur Hauptstromwicklung u.By choosing the right proportions, anyone can Course of the DC voltage supplied by the converter g can be achieved. So it is a falling, a constant, or a rising voltage characteristic can be set The resistance v in series with the shunt winding P allows as required a shift of the saturation point of the iron core j, in the desired sense. The same effect can also be achieved by using a shunt to main current winding u.
In Fig. i stellt g einen Gleichrichter dar, mit den Anoden a1, a2 und der Kathode k. Die Stromabnahme erfolgt bei m. Der Nullpunkt des Transformators t ist über Leitungn und u an die Minusklemme des Verbrauchsstromkreises m angeschlossen. An Stelle des Gleichrichters -ist auch ein Einankerumformer verwendbar (Fig. 2).In Fig. I, g represents a rectifier, with the anodes a1, a2 and the cathode k. The current is drawn at m, the zero point of the transformer t is connected via lines and u to the negative terminal of the consumption circuit m. Instead of the rectifier, a single armature converter can also be used (Fig. 2).
Der Übersichtlichkeit halber enthält Fig. i und 2 .die Schaltung für den Fall eines E nphasenumformers. Die Übertragung derselben auf einen Mehrphasenumformer ergibt sich ohne weiteres, und würde z. B. im Falle eines Sechsphasengleichrichters die aus Fig. i ersichtlicLe Einrichtung die an eine Transformatorsäule angeschlossenen Teile in sich schließen: Die Erregerwicklung e, d des Zusatztransformators i muß nicht an den Haupttransformator t angeschlossen werden ;;sie kann selbstverständlich auch mit einer beliebigen Wechselstromquelle, deren Periodenzahl mit der Grundperiodenzahl ü-reinstimmt, verbunden werden. Ferner können die Gleichstromwicklungen u und p gemeinsam oder allein verwendet und auch von einer vom Nutzstrom unabhängigen Gleichstromquelle gespeist werden,. sofern es lediglich um eine bestimmte Einstellung der' gleichgerichteten Spannung handelt.For the sake of clarity, FIGS. 1 and 2 contain the circuit for the case of a phase converter. The transfer of the same to a polyphase converter is easy, and would, for. B. in the case of a six-phase rectifier i ersichtlicLe means conclude from Fig connected to a transformer column parts in itself. The excitation winding E, D of the auxiliary transformer i need not be t is connected to the main transformer ;; it can of course also with any AC power source, whose number of periods agrees with the basic number of periods. Furthermore, the direct current windings u and p can be used jointly or alone and can also be fed from a direct current source independent of the useful current. as long as it is only about a certain setting of the 'rectified voltage.
