Description
Zur Spannungsregelung bei Einankerumformern und Quecksilberdampfgleichrichtern o. dgl., die vom Netz über einen Transformator gespeist werden, über einen zusätzliehen Drehtransformator war es bisher üblich, den Anschluß desselben auf der Niederspannungsseite des Transformators vorzunehmen. Es mußte daher auch die Drehtransformatorleistung durch den Haupttransformator hindurchgehen. Da die Drehtransformatorleistung häufig 25 und mehr Prozent der eigentlichen Transformatorleistung beträgt, mußte der Haupttransformator entsprechend ausgelegt werden. Hier- durch erhöhten sich sowohl die Anlagekosten als auch die im Betriebe auftretenden Transformatorverluste. For voltage regulation in single armature converters and mercury vapor rectifiers or the like, which are fed from the network via a transformer, via an additional Rotary transformer, it was customary to connect the same on the low voltage side of the transformer to undertake. The rotary transformer output therefore also had to go through the main transformer go through. Since the rotary transformer output is often 25 percent or more of the actual transformer output the main transformer had to be designed accordingly. This increased both the investment costs as well as the transformer losses occurring in the company.
Diese Nachteile lassen sich dadurch vermeiden, daß die dem Drehtransformator zuge-These disadvantages can be avoided by the fact that the
ao führte Leistung dem Netz bereits vor dem Haupttransformator entnommen wird. Da es hier erforderlich wird, den Drehtransformator für die Oberspannung zu bemessen, ergibt sich zwar ein höherer Anschaffungspreis für den Drehtransformator, aber der Wirkungsgrad der Gesamtanlage wird erheblich verbessert. Hinzu kommt, daß der Haupttransformator entsprechend kleiner bemessen werden kann.ao led power is taken from the network before the main transformer. Because it Here it is necessary to dimension the rotary transformer for the high voltage, results Although a higher purchase price for the rotary transformer, but the efficiency the overall system is significantly improved. In addition, the main transformer can be dimensioned correspondingly smaller.
Gegenstand der Erfindung ist eine Verbesserung und Vervollkommnung dieser bekannten Drehtransformatorschaltung. Erfindungsgemäß wird die Erregerwicklung des Drehtransformators mit einer Umschalteinrichtung verbunden, durch die diese Wicklung wahlweise entweder an die Oberspannungsseite oder an die Niederspannungsseite des Haupttransformators anschließbar ist. Diese Anordnung hat den Vorteil, daß der Drehtransformator auch zur Herabsetzung der Grundspannung des Haupttransformators verwendet werden kann. Da die Energie des Drehtransformators in diesem Falle in entgegengesetzter Richtung fließt, ist es zweckmäßig, die Belastung des Haupttransformators dadurch zu verringern, daß der Drehtransformator bei gewünschter Herabsetzung der Grundspannung des Haupttransformators auf dessen Niederspannungsseite anschließbar ist. Dies setzt voraus, daß der Rotor des Drehtransformators sowohl für die Oberspannung bei kleineren Stromstärken als auch für die Niederspannung'bei großen Stromstärken bemessen ist. Denn nur dann kann der Rotor durch den Umschalter sowohl an die Hoch-Spannungsseite als auch an die Niederspannungsseite angeschlossen werden. Die Umschaltung erfolgt zweckmäßig in Abhängigkeit von einem Energierichtungsrelais.The object of the invention is to improve and perfect these known ones Rotary transformer circuit. According to the invention, the field winding of the rotary transformer connected to a switching device, through which this winding either to the high-voltage side or can be connected to the low-voltage side of the main transformer. This arrangement has the advantage that the rotary transformer also reduces the basic voltage of the main transformer can be used. Because the energy of the rotary transformer in this case flows in the opposite direction, it is useful to reduce the load on the main transformer to reduce that the rotary transformer at the desired reduction of the The basic voltage of the main transformer can be connected to its low-voltage side. This assumes that the rotor of the rotary transformer is suitable for both the high voltage for smaller currents as well as for the low voltage 'with large currents is. Because only then can the rotor through the changeover switch both to the high-voltage side as well as to the low voltage side. The switchover is expediently carried out as a function from an energy direction relay.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schaltungsschema dargestellt. Der Verbraucher 4, beispielsweiseIn the drawing, an embodiment of the invention is shown in the circuit diagram. The consumer 4, for example
ein Einankerumformer, ist über einen Haupttransformator ι an das Drehstromnetz 3 angeschlossen. Zum Zwecke der Veränderung der dem Einankerumformer zuzuführenden Wechselspannung ist zwischen dem Haupttransformator ι und dem Einankerumformer 4 ein Drehtransformator 2 geschaltet. Die Erregerwicklung dieses Transformators ist mit einem Umschalter 5 verbunden, über den die Erregerleistung des' Drehtransformators entweder auf der Oberspannungsseite oder auf der Niederspannungsseite des Haupttransformators ι entnommen werden kann. Soll dem Umformer 4 eine höhere Spannung als die Grundspannung zugeführt werden, so wird der Schalter 5 an die Kontakte 6 gelegt. Ist die erforderliche Spannung dagegen geringer, als die Grundspannung, so wird der Umschalter 5 an die Kontakte 7 angeschlossen. In jedem Fall ist die Schaltungsanordnung derart getroffen, daß sich eine günstige Energieverteilung ergibt. Beim Anschluß der Erregerwicklung des Drehtransformators auf der Oberspannungsseite des Haupttransformators fließt durch diesen lediglich die der Grundspannung entsprechende Energie, während der Haupttransformator durch die Erregerenergie des Drehtransformators nichta single armature converter is connected to the three-phase network 3 via a main transformer ι. For the purpose of changing the AC voltage to be fed to the single armature transformer, there is a connection between the main transformer ι and the single armature converter 4, a rotary transformer 2 connected. The excitation winding this transformer is connected to a changeover switch 5, via which the excitation power of the rotary transformer either on the high-voltage side or on the low-voltage side of the main transformer ι can be taken. Should the converter 4 have a higher voltage than that Basic voltage are supplied, the switch 5 is applied to the contacts 6. is the required voltage, however, is less than the basic voltage, so the changeover switch 5 connected to contacts 7. In any case, the circuit arrangement is such taken that there is a favorable energy distribution. When connecting the excitation winding of the rotary transformer on the high-voltage side of the main transformer, only that of the flows through it Basic voltage corresponding energy, while the main transformer by the excitation energy the rotary transformer does not
belastet wird. Bei Herabsetzung der Grundspannung durch den Drehtransformator fließt 3° dagegen die Energie des Drehtransformators in umgekehrter Richtung. Die Belastung des Haupttransformators wird daher vermindert, wenn gemäß der Erfindung die Erregerwicklung des Drehtransformators auf der Nieder- 35 Spannungsseite des Haupttransformators angeschlossen ist.is charged. If the basic voltage is reduced by the rotary transformer, 3 ° flows on the other hand, the energy of the rotary transformer in the opposite direction. The burden of the Main transformer is therefore reduced when, according to the invention, the field winding of the rotary transformer is connected to the low voltage 35 side of the main transformer is.
