Description
Es ist bekannt, Transformatoren für Gleichrichter mit sechs Anoden in Stern-Sechsphasen-Schaltung zu benutzen. Diese Schaltung hat den Vorteil, daß oberhalb einer be-S stimmten Belastung immer zwei benachbarte Anoden gleichzeitig Strom führen müssen. Dieser Zwang bewirkt eine Überlappung der Phasenströme und eine günstigere Ausnutzung der Wicklung. Andererseits ist aber die ίο Spannung bei gleichzeitigem Brennen zweier Anoden niedriger, als wenn nur eine Anode Strom führt. Bei kleinen Belastungen, bei denen der Zwang zu gleichzeitigem Brennen zweier Anoden nicht mehr in genügendem Maße besteht, -steigt die Spannung daher plötzlich, und zwar um einen Wert von etwa 150/0.It is known transformers for rectifiers with six anodes in star-six-phase connection to use. This circuit has the advantage that above a certain load there are always two adjacent ones Anodes must carry current at the same time. This constraint causes the Phase currents and a more favorable utilization of the winding. On the other hand, it is ίο Voltage lower when two anodes are burning than when only one anode is burning Current leads. With small loads, where the compulsion to burn at the same time two anodes no longer exists to a sufficient extent, the voltage therefore rises suddenly, by a value of about 150/0.
Um auch bei kleinen Belastungen das gleichzeitige Stromführen von zwei Anoden zu erzwingen, gibt man dem Transformator einen oder mehrere Hilfsschenkel, die keine der Transformierung dienende Wicklung tragen. Man erreicht dadurch, daß in jedem Augenblick auf jedem der Hauptschenkel die »5 Summe der Amperewindungen bis auf den Anteil des primären Leerlaufstromes gleich Null ist. Die Wirkung kann gemäß vorliegender Erfindung noch verstärkt werden, wenn man die dem Nullpunkt zugekehrten Enden der sechs Phasen zu je dreien vereinigt und die Verbindungspunkte über zwei Wicklungen, die auf einem Hilfsschenkel angeordnet sind, zum Transformatornullpunkt zusammenschließt. Diese Wicklungen sind gegeneinander zu schalten. In order to be able to carry current from two anodes at the same time, even with small loads To force, one gives the transformer one or more auxiliary legs, which are not carry the transformation serving winding. One achieves that in each Moment on each of the main legs the 5 sum of the ampere-turns except for the Proportion of the primary no-load current is zero. The effect can be according to the present Invention can be reinforced if the ends of the six phases facing the zero point are combined into three and the connection points via two windings arranged on an auxiliary leg, connects to the transformer zero point. These windings are to be switched against each other.
In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die drei Schenkel α eines Transformators tragen die Wicklungen b, deren Anfänge und Enden mit den einzelnen Anoden des Gleichrichters zu ¥> verbinden sind. Die Wicklungen b sind in der Mitte aufgeschnitten; die oberen Hälften und die unteren Hälften sind für sich zu Hilfswicklungen / geführt, die auf dem Hilfsschenkel e angeordnet und gegeneinander geschaltet sind. Die Enden dieser Hilfswicklungen bilden den Nullpunkt*/.In the figure, an embodiment of the invention is shown. The three legs of a transformer α b carry the windings, are connect their beginnings and ends with the individual anodes of the rectifier to ¥>. The windings b are cut open in the middle; the upper halves and the lower halves are individually led to auxiliary windings / which are arranged on the auxiliary leg e and connected to one another. The ends of these auxiliary windings form the zero point * /.
