 gebracht werden kann,    wobei die drei Phasen trotzdem nahezu gleich belastet sind. Sa ist selbst-     verständlich,   dass statt drei einfachen Elektroden, wie in der Zeichnung dargestellt, auch drei Gruppen von Elektroden zur Verwendung kommen können. 



   Ebenso könnte der Nulleiter mit dem Bad an mehr wie zwei Stellen verbunden werden. 



   PATENT -ANSPRÜCHE :
1. Einrichtung zum Betrieb elektrischer Ofen mit Dreiphasenstrom, wobei die Elektroden mit den in Sternschaltung liegenden   Sekundärwicklungen   der   Speisetranaformatoron   verbunden sind, welche andererseits durch den gemeinsamen Leiter mit der leitenden Herdplatte in Verbindung stehen, dadurch gekennzeichnet, dass die eine der Phasen in der Sternschaltung umgekehrt ist, so dass zwischen je einer Elektrode und dem Bad, sowie zwischen zwei der Elektroden je die Phasenspannung besteht, während zwischen zwei anderen Elektroden die Netzspannung herrscht, zum Zwecke, bei gleicher Verteilung der Belastung auf die drei Phasen durch diese Spannungsverteilung den Stromübergang von den Elektroden durch das Bad zu bewirken.

 can be brought, although the three phases are almost equally loaded. It goes without saying that instead of three simple electrodes, as shown in the drawing, three groups of electrodes can also be used.



   Likewise, the neutral conductor could be connected to the bathroom in more than two places.



   PATENT CLAIMS:
1. Device for operating an electric furnace with three-phase current, the electrodes being connected to the star-connected secondary windings of the Speisetranaformatoron, which on the other hand are connected to the conductive hotplate through the common conductor, characterized in that one of the phases in the star connection is reversed so that the phase voltage exists between each electrode and the bath, as well as between two of the electrodes, while the mains voltage prevails between two other electrodes, for the purpose, with the same distribution of the load on the three phases, the current transfer from the To effect electrodes through the bath.

Claims (1)

2. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Umkehrung der Phase durch Umkehrung der Sekundärwicklung des betreffenden Transiormators bewirkt wird. 2. Embodiment of the device according to claim 1, characterized in that the reversal of the phase is effected by reversing the secondary winding of the relevant Transiormator. 3. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Umkehrung der Phase durch die Umkehrung der Primärwicklung des betreffenden Transformators erhalten wird. 3. Embodiment of the device according to claim 1, characterized in that the reversal of the phase is obtained by reversing the primary winding of the transformer in question.
