Description
Es ist bereits bekannt, in Wechselstromverteilungsanlagen die Spannung durch Verwendung von Zusatztransformatoren in gewissen. Grenzen zu ändern. Um dabei eine stufenlose Regelung zu erhalten, kann man einen Potentialregler verwenden. Das geschieht zweckmäßig in der Weise, daß die Erregerwicklung des Zusatztransformator über den Potentialregler gespeist wird.It is already known in AC power distribution systems the voltage by using additional transformers in certain. Change boundaries. A potential regulator can be used to achieve stepless regulation. This happens expedient in such a way that the excitation winding of the additional transformer is fed via the potential regulator.
ίο Es ist nun von Wichtigkeit, daß der Zusatztransformator ein- bzw. ausgeschaltet werden kann, ohne den Betrieb der Anlage störend zu beeinflussen. Erfindungsgernaß soll zu diesem Zwecke die Anordnung so getroffen werden, daß der Potentialregler in an sich bekannter Weise in Sparschaltung mit einem Übersetzungsverhältnis von annähernd 1:1 ausgeführt und dem Zusatztransformator ein Überbrückungsschalter parallel gelegt wird. Wenn, die dem Potentialregler primär zugeführte Spannung e ist, ergibt sich demgemäß an den Sekundärklemmen des Potentialreglers je nach der Einstellung eine Spannung zwischen ο -— 2 e, und dementsprechend ändert sich die Zusatzspannung. Mit der Spannung an den Sekundärklemmen des Potentialreglers wird insbesondere auch die Zitsatzspannung gleich Null. In diesem Falle kann aber durch Einlegen des ÜberbrückungSBchalters ohne weiteres die Abschaltung vorgenommen werden, und ebenso läßt sich die Zuschaltung bewirken.ίο It is now important that the additional transformer can be switched on and off without interfering with the operation of the system. According to the invention, the arrangement is to be made so that the potential regulator is executed in a known manner in economy circuit with a transmission ratio of approximately 1: 1 and the additional transformer is placed in parallel with a bypass switch. If the voltage that is primarily supplied to the potential regulator is e , a voltage between o-2 e results at the secondary terminals of the potential regulator, depending on the setting, and the additional voltage changes accordingly. With the voltage at the secondary terminals of the potential regulator, the instantaneous voltage in particular also becomes equal to zero. In this case, however, the disconnection can easily be carried out by inserting the bridging switch, and the connection can also be effected.
In' der Zeichnung ist ein Ausführungsbeispiel für die neue Anordnung veranschaulicht. A ist danach ein an dem Wechselstrom- 3-5 netz liegender Spannungstransformator, der die Erregerwicklung 'des Potentialreglers B speist. Der Potentialregler B ist in Spar-In 'the drawing, an embodiment of the new arrangement is illustrated. A is then a voltage transformer connected to the alternating current 3-5 mains, which feeds the field winding 'of the potential regulator B. The potential regulator B is in economy

The additional winding b of this additional transformer can by means of the Eeastungssehalters c

Um den Zusatztransformator C abzuschalten, ist es alsdann nur nötig, den Potentialregler B in eine solche Stellung zu bringen, daß die Spannung an seinen SekundärklemmenIn order to switch off the additional transformer C , it is then only necessary to bring the potential regulator B into such a position that the voltage is applied to its secondary terminals

Nachdem dies geschehen ist, kann der Zusatztransformator C und ebenso der Spannungstransformator A ganz vom Netz abgetrennt werden, so daß diese Transformatoren A1 C nebst dem Potentialregler B spannungslos sind und so etwaige erforderliche Ausbesserungsarbeiten ohne weiteres daran vorgenommen werden können. Zum Wiedereinschalten wird die Zu-to becomes approximately zero, and then insert the bypass switch c. After this has been done, the additional transformer C and also the voltage transformer A can be completely disconnected from the mains, so that these transformers A 1 C and the potential regulator B are de-energized and any necessary repair work can be carried out on them without further ado. To switch it on again, the

Unter Umständen ist es zweckmäßig, einen Überbrückungsschalter auch noch parallel zur Erregerwicklung α des Zusatztransformators C zui legen. Der Überbrückungsschalter c kann dabei ganz wegfallen, wenn es sich nur darum handelt, den Potentdalregler B, nicht den Zusatztransformator C, selbst ab- bzw. einzuschalten. Under certain circumstances it is advisable to also place a bridging switch parallel to the field winding α of the additional transformer C. The bypass switch c can be omitted entirely if it is only a question of switching the potentiometer B, not the additional transformer C, itself on or off.
. Falls sowohl die Erregerwicklung α als die Zusatzwicklung b des Zusatztransformators C durch einen Schalter überbrückt werden können, läßt sich der Überbrückungsschalter für die Zusatzwicklung b als (einfacher Trennschalter ausbilden.. If both the excitation winding α as the auxiliary winding b of the auxiliary transformer C by a switch can be bridged, the bridging switch for the auxiliary winding can form as b (simple disconnector.
