Für viele Zwecke, z. B. Umformung von Mehrphasenstrom, ist es vorteilhaft, die Phasenzahl in hekannter Weise durch einen Transformator zu verdoppeln, weil dadurch die Umformer bedeutend besser ausgenutzt werden. Besonders vorteilhaft ist eine derartige Umformung bei Quecksilberdampfgleichrichtern, bei denen durch Vermehrung der Phasenzahl die Oberschwingungen bedeutend vermindertFor many purposes, e.g. B. Conversion of multiphase electricity, it is advantageous to change the number of phases doubled in the known way by a transformer, because this means the converter can be used significantly better. Such a deformation is particularly advantageous in the case of mercury vapor rectifiers, in which the harmonics are significantly reduced by increasing the number of phases

Der Anwendung der Verdopplung der Phasen stand beim Regulieren der Nachteil gegenüber, daß der Regulierschalter sechsphasig ausgeführt werden mußte, wenn man nicht in der Primärwicklung, die meistens Hochspannung führt, regulieren wollte. Der Regulierschalter wurde dadurch einesteils sehr groß und teuer, andererseits wurde die doppelte Anzahl der Verbindungsleitungen erforderlieh. The use of the doubling of the phases was offset by the disadvantage in regulating that the regulating switch had to be carried out with six phases, if one is not in the primary winding, which is mostly high voltage leads, wanted to regulate. As a result, the control switch became very large on the one hand and expensive, on the other hand, double the number of connecting lines was required.
Die Erfindung ermöglicht nun eine Regulierung in nur η-Phasen bei 2 n-phasiger Anordnung. Sie besteht darin, daß die Regulierung jeder zweiten der aufeinanderfolgenden 2 η-Phasen durch Kurzschließen von Regulierstufen an deren Nullpunkt erfolgt, während die zwischen diesen Phasen liegenden Phasen je an eine Regulierstufe der vorhergehenden Phase angeschlossen sind.The invention now enables regulation in only η phases with a 2 n-phase arrangement. It consists in regulating every second of the successive 2 η phases by short-circuiting regulating stages to their zero point, while the phases lying between these phases each to a regulation level of the previous one Phase are connected.
In der Zeichnung ist ein Anwendungsbeispiel für Umformung von drei auf sechs Phasen dargestellt. In Fig. 1 ist bei dem sechsphasigen Transformator die Regulierung in den Nullpunkt der um 120 ° verschobenen Phasen i, 3 und 5 verlegt, während die Phase 2, die um 180 ° gegen Phase 5 verschoben ist, ungefähr in der Mitte der Regulierstufen der Phase 1 an diese angeschlossen ist, ebenso Phase 4 sinngemäß an Phase 3 und Phase 6 sinngemäß an Phase 5.The drawing shows an application example for forming from three to six phases shown. In Fig. 1, the regulation is in the six-phase transformer Zero point of phases i, 3 and 5 shifted by 120 ° relocated, while phase 2, the is shifted by 180 ° against phase 5, approximately in the middle of the regulating stages of the Phase 1 is connected to this, as is phase 4 analogously to phase 3 and phase 6 analogously to phase 5.
Dadurch erhält man ein Kreisdiagramm, wie Fig. 2 zeigt. Man erkennt, daß die Phasen genau um 60 ° differieren, wenn der Regulierschalter die Kontakte c verbindet. Zu den Wicklungen 1, 4, 3, 6, 2, 5, die Sekundärwicklungen eines Transformators darstellen, sind die zugehörigen Primären, dreiphasigen Wicklungen zu denken. Es findet also eine Spannungserhöhung statt, wenn die Punkte d, β, und eine Spannungserniedrigung, wenn die Punkte b, α durch den Regulierschalter kurzgeschlossen werden, wobei man die Lage, bei welcher die Punkte c durch den Regulierschalter kurzgeschlossen sind, als Mittellage ansieht, von der ausgegangen wird. Während die Phasen 2, 4, 6 bei höheren Spannungen, z. B. wenn der Regulierschalter die Punkte e verbindet, der Mittellage gegenüber etwas nacheilen, werden sie bei niederer Spannung, z. B. wenn die Punkte α miteinander verbunden sind, der Mittellage gegenüber etwas voreilen. Doch hat diese geringe Verschiebung der Symmetrie praktisch keine Bedeutung. This gives a circle diagram as shown in FIG. It can be seen that the phases differ by exactly 60 ° when the regulating switch connects the contacts c. For the windings 1, 4, 3, 6, 2, 5, which represent the secondary windings of a transformer, the associated primary, three-phase windings are to be considered. So there is an increase in voltage when points d, β, and a decrease in voltage when points b, α are short-circuited by the regulating switch, whereby the position at which points c are short-circuited by the regulating switch is viewed as the middle position, which is assumed. While phases 2, 4, 6 at higher voltages, e.g. B. when the control switch connects the points e, lag slightly behind the central position, they are at low voltage, z. B. when the points α are connected to each other, lead the middle position slightly. But this slight shift in symmetry has practically no meaning.
