Description
Schaltungseinrichtung für Zusatztransformatoa#en. Die Erfindung betrifft eine besondere Schaltungseinrichtung für Zusatztransforma toren, welche dazu bestimmt sind, in einem Wechsel- beziehungsweise 'Mehrphasenstrom- netz zusätzliche Spannungen zu erzeugen, die während des Betriebes in vorgeschriebenen Stufen und auch in ihrem Vorzeichen geregelt werden sollen. Die sekundäre Wicklung des Zusatztransformators bleibt erfindungsgemäss dauernd in Reihe zu der Netzleitung einge schaltet.
Die primäre Wicklung, die mit einer oder mehreren Abstufungen ausgerüstet ist, kann sowohl im einen als im andern Wick lungssinn an die Netzspannung geschaltet, und sowohl im Ganzen als in Abstufungen kurzgeschlossen werden.
Bei Kurzschluss der primären Wicklung wird auch die sekundäre Wicklung angenähert ohne Spannung und die Zusatzspannung also Null sein. Dabei wird es gleichgültig sein, welche Teile der sekundären Wicklung kurz- geschlössen werden. Je nachdem nun eine grössere oder kleinere Anzahl von Windungen der ,primären Wicklung im einen oder andern Sinne an die Netzspannung geschlossen wer den, wird in der sekundären Wicklung eine kleinere oder grössere Zusatzspannung mit dem einen oder andern Vorzeichen induziert.
Zweckmässigerweise wird nun ein besonderer Schalter vorgesehen werden, welcher den Anschluss der Netzspannung bewirkt, und eine Umschaltvorrichtung, welche die Kurz schlussverbindungen und allfällige Umschal tungen der primären Wicklungen bei-unter- brochenerNetzspannung und kurzgeschlossener Wicklung vollzieht, zum Beispiel in Form einer Kontrollerwalze, die mitdem Netzschalter in geeigneter Weise zu verriegeln ist.
Selbstverständlich kann auch für besondere Erfordernisse die sekundäre Wicklung für verschiedene Spannungsbereiche eingerichtet werden, wobei diese Einstellung im stromlosen Zustand auszuführen wäre.
In der beiliegenden, schematischen Figur ist als Ausführungsbeispiel des Erfindungs gegenstandes ein Einphasen-Zusatztransfor- mator gezeichnet, dessen sekundäre Wick lung l in Reihe zu der Netzleitung<I>L</I> ge schaltet ist. Die primäre Wicklung 2 ist in zwei Abteilungen mit den Schaltern 3, 4, 5 verbunden. Diese Schalter gestatten, die Wick lungsabteilungen einzeln oder zusammen kurz- zuschliessen oder in passender Weise mit den Kontakten 12 und 13 zu verbinden. Nachdem die richtige Einstellung der Schalter 3, 4, 5 getroffen ist, kann der Netzschalter 14, 15 geschlossen werden.
Switching device for additional transformers. The invention relates to a special circuit device for additional transformers, which are intended to generate additional voltages in an alternating or 'Mehrphasenstrom- network, which should be regulated in prescribed stages and also in their sign during operation. According to the invention, the secondary winding of the additional transformer remains permanently switched on in series with the power line.
The primary winding, which is equipped with one or more gradations, can be connected to the mains voltage in one or the other winding sense, and short-circuited both as a whole and in gradations.
If the primary winding is short-circuited, the secondary winding will also be approximately without voltage and the additional voltage will therefore be zero. It will not matter which parts of the secondary winding are short-circuited. Depending on whether a larger or smaller number of turns of the primary winding is connected to the mains voltage in one sense or the other, a smaller or larger additional voltage with one sign or the other is induced in the secondary winding.
Appropriately, a special switch is now provided, which effects the connection of the mains voltage, and a switching device, which carries out the short-circuit connections and any switching of the primary windings when the mains voltage is interrupted and the winding is short-circuited, e.g. The mains switch must be locked in a suitable manner.
Of course, the secondary winding can also be set up for different voltage ranges for special requirements, this setting being carried out in the de-energized state.
In the accompanying schematic figure, as an exemplary embodiment of the subject matter of the invention, a single-phase additional transformer is drawn, the secondary winding of which is connected in series with the power line. The primary winding 2 is connected to the switches 3, 4, 5 in two sections. These switches allow the winding departments to be short-circuited individually or together, or to be connected to contacts 12 and 13 in a suitable manner. After the correct setting of the switches 3, 4, 5 has been made, the power switch 14, 15 can be closed.
