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.
