Description

Es sind Einrichtungen bekannt, die einem Dreiphasennetz mittels zweier Transformatoren zwei Spannungen entnehmen, die um 9o° gegeneinander phasenverschoben sind. Die bekanntesten Schaltungen dafür sind die Scottsche und die Sonnsche Schaltung. Durch geeignete Zusammenschaltung der Sekundärspannungen lassen sich Spannungen in beliebiger Phasenlage und Größe bilden. Ist die Sekundärseite als Regler ausgebildet, so bestreicht man damit- einen Regelbereich von 9o°.There are devices known that a three-phase network by means of two Transformers take two voltages that are 90 ° out of phase with one another are. The best-known circuits for this are the Scott and Sonnian circuits. By suitably interconnecting the secondary voltages, voltages form in any phase position and size. If the secondary side is designed as a regulator, so you can cover a control range of 9o °.

Erfindungsgemäß sind zwei Reguliertransformatoren vorgesehen, deren Primärwicklungen in einer 9o°-Schaltung, z. B. der Scott-Schaltung, von einem Dreiphasennetz gespeist werden, und deren sekundäre Regelwicklungen je einen Mittelabgriff und je einen Regelabgriff besitzen. Ein Abgriff des einen Reglers isst mit einem Abgriff des anderen Reglers verbunden, während die zwei noch freien Abgriffe zur Entnahme der geregelten Spannung dienen, so daß ohne Schaltungsänderung während des Gebrauches eine vektorielle Spannungsregelung über alle vier Quadranten. des Koordinatensystems möglich ist. Die Ausgangsspannung wird also durch Zusammensetzung zweier Spannungen gebildet, von denen die eine in Richtung der x-Achse eines Koordinatensystems mit vier Quadranten gedacht werden kann und die andere in Richtung der y-Achse dieses Systems, derart, daß jede der beiden Spannungen ihren Ausgang aus dem Nullpunkt des Koordinatensystems nimmt und, je. nachdem . der zugehörige Regler mit seinem Abnehmer auf der einen oder der anderen Seite der Regleranzapfung arbeitet, im Koordinatensystem. nach links oder rechts bzw. nach oben oder nach unten liegend gedacht werden kann. Der resultierende Spannungsvektor kann bei .den möglichen Reglerstellungen jede beliebige Lage und Größe innerhalb der vier Quadranten des Koordsnafiensystems einnehmen und ermöglicht somit eine Spannungsregelung beliebiger Höhe und Phasenlage.According to the invention, two regulating transformers are provided, the primary windings of which in a 9o ° circuit, e.g. B. the Scott circuit, are fed by a three-phase network, and their secondary control windings each have a center tap and a control tap. A tap of one regulator is connected to a tap of the other regulator, while the two taps that are still free serve to draw the regulated voltage, so that vector voltage regulation over all four quadrants without changing the circuit during use. of the coordinate system is possible. The output voltage is thus formed by combining two voltages, one of which can be thought of in the direction of the x-axis of a coordinate system with four quadrants and the other in the direction of the y-axis of this system, in such a way that each of the two voltages has its output the zero point of the coordinate system takes and, depending. after this . the associated controller works with its consumer on one side or the other of the controller tap, in the coordinate system. can be thought of lying to the left or right or upwards or downwards. The resulting voltage vector can assume any position and size within the four quadrants of the coordinate system with the possible controller settings and thus enables voltage regulation of any height and phase position.

Abb. i zeigt ein Schaltungsbeispiel dieser Art. Hierin ist i die Primärwicklung des in der x-Achse arbeitenden Reglers, 2 die Primärwicklung des in der y-Achse arbeitenden Reglers. Die beiden Primärwicklungen sind .in der als. Scottsche Schaltung bekannten Art mit den drei Phasen R, S, T des speisenden Drehstromnetzes verbunden. Die Sekundärwicklung 3- des x-Reglers. und die Sekundärwicklung q. _des y-Reglers sind mit ihren Mittelabgriffen miteinander verbunden. Die resultierende Spannung wird mittels der Schleifer 5 und 6 abgenommen.Fig. I shows an example of this type of circuit. Here i is the primary winding of the controller working in the x-axis, 2 the primary winding of the in the y-axis working regulator. The two primary windings are in the as. Scottish circuit known type connected to the three phases R, S, T of the feeding three-phase network. The secondary winding 3- of the x controller. and the secondary winding q. _of the y-controller are linked to one another with their resource tapping. The resulting tension is removed using the grinder 5 and 6.

Es ist für die Wirkung gleichgültig; ob an Stelle der Mittelpunktverbindung die Schleifer verbunden werden und dafür die Abnahme an den Mittelpunkten erfolgt oder auch je ein Schleifer des einen Reglers mit dem Mittelpunkt des anderen Reglers verbunden wird und de Abnahme an dem noch freien Regler und Mittelpunkt erfolgt.It is indifferent to the effect; whether instead of the midpoint connection the grinders are connected and for this the decrease takes place at the midpoints or a slider of one controller with the center of the other controller is connected and de acceptance takes place on the controller and center point that are still free.

Die beschriebene Schaltung kann noch durch eine zusätzliche Feinregelung erweitert werden, wie in Abb. 2 dargestellt. Hierbei werden die von den Schleifern 7 (für x-Achse) und 8 (für y-Achse) abgenommenen Spannungen über je einen Abwärtstransformator in der für Feinregelzwecke erforderlichen Größe,der vom jeweiligen Grobregler abgenommen.en Spannung aufgedrückt.The circuit described can still be controlled by an additional fine control can be expanded as shown in Fig. 2. This is done by the grinders 7 (for x-axis) and 8 (for y-axis) taken voltages via a step-down transformer each in the size required for fine control purposes, which is accepted by the respective coarse controller Tension imposed.

An Stelle der transformatorischen Regelung kann auch die -Verwendung rein ohmscher Regler treten. Am Regelprinzip wird dadurch nichts geändert.Instead of the transformer regulation, -use can also be used step purely ohmic regulator. This does not change anything in the control principle.
