  Einrichtung zur Aufrechterhaltung vorgegebener Verhältnisse zwischen den Strömen in an die selbe Wechselspannungsquelle angeschlossenen Verbrauchern bzw. Leitern, insbesondere den Elektrodenzuleitungen von Wechselstromelektroöfen 
Die Erfindung bezieht sich auf das Patent   Nr. 199382. das eine Einrichtung   zur Aufrechterhaltung vor-   gegebener Verhältnisse zwischen   den Strömen in an die selbe Wechselspannungsquelle angeschlossenen Ver-   brauchembzw.   Leitern, insbesondere den Elektrodenzuleitungen   von Wechselstromelektroöfen   mit   Indue-     tivitäten   zum Gegenstand hat, welche wenigstens je zwei aus mindestens einem Leiter bestehende Leitergruppen magnetisch koppeln und in welcher wenigstens zwei solche Induktivitäten einen gemeinsamen.

   Wenn ein gemeinsamer Kein für alle Leiter je Phase oder alle Leiter für sämtliche Phasen benutzt wird, so werden sich die zwischen den Leitern induzierten Spannungen von einem von der Kupplung abhängigen Symmetriepunkt her addieren. Dies bewirkt, dass der Eisenkern grösser dimensioniert werden muss und an Gewicht mehr zunimmt als der erhöhten Anzahl an Leitern entspricht. 



   Dies ist besonders da merkbar, wo viele Leiter in zwei oder mehreren Ebenen angeordnet sind und wo

   Wie aus dem Beispiel hervorgeht, hat die zwischen den beiden Ebenen auftretende Spannung auf den Eisenkern 21 keine Wirkung.

  Device for maintaining predetermined ratios between the currents in consumers or conductors connected to the same AC voltage source, in particular the electrode leads of AC electric ovens
The invention relates to patent no. 199382, which contains a device for maintaining given relationships between the currents in consumption and / or power consumption connected to the same AC voltage source. Conductors, in particular the electrode leads of AC electric furnaces with inductivities, which magnetically couple at least two conductor groups consisting of at least one conductor and in which at least two such inductors have a common one.



  Have iron core which is provided with a window for each pair of conductors or groups of conductors to be coupled with these last-mentioned inductances.



   If a common none is used for all conductors per phase or all conductors for all phases, the voltages induced between the conductors will add up from a point of symmetry that is dependent on the coupling. This has the effect that the iron core has to be dimensioned larger and its weight increases more than corresponds to the increased number of conductors.



   This is particularly noticeable where and where many conductors are arranged in two or more levels
 EMI1.1
 



  The balancing between the individual conductors of the group is carried out according to patent no. 199382.



   An exemplary embodiment of the invention is shown in the drawing, in which Fig. 1 shows schematically the arrangement of the conductors of one phase and Fig. 2 shows the arrangement of the three phases on a smaller scale.



   In this embodiment, twenty cables per phase are provided in two parallel, vertical planes with ten cables in each plane. The cables of the phase shown in FIG. 1 are labeled 1, 2, 3, ... 20. A voltage from the remaining phases is generated between the lines in the levels mentioned

   As can be seen from the example, the tension occurring between the two planes has no effect on the iron core 21.



   This means that the iron core 21 turns out to be significantly smaller than if it were between the two

 this core exceeds the weight of the core 22, so that the overall weight is reduced.
