Elektrodenanordnung für elelrtrische Schmelzöfen.
Bei den bisherigen Elektrodenanordnungen für mehrphasigen Wechselstrom pflegen die Elektroden um 1200 oder 2 x 900 gegeneinander versetzt zu werden. Zur Erzielung annähernd gleicher Phasenbelastung werden alle drei Elektroden reguliert, wodurch entweder höhere Bedienungskosten oder drei selbsttätige Regler erforderlich werden.
Durch vorliegende Erfindung wird eine der Regelungen erspart. Der Erfindung gemäss werden bei Drehstrom zwei Elektroden unter einem Winkel von 600 zueinander und jede von diesen zu der dritten Elektrode unter einem Winkel von 1500 angeordnet. Bei verkettetem Zweiphasen-Wechselstrom werden zwei Elektroden zueinander unter einem Winkel von 90 und jede von diesen zur dritten Elektrode unter einem Winkel von 1350 angeordnet.
In der Zeichnung sind diese zwei Elektrodenanordnungen für Schmelzöfen schematisch dargestellt.
Die Anordnung nach Fig. 1 gilt für Drehstrom. Die Elektrode E braucht nicht regelbar zu sein.
EMI1.1
Elektrode E einen Winkel von 1500 einschliessen.
Die Anordnung nach Fig. 2 gilt für verketteten Zweiphasenstrom. Regelbar sind nur die beiden Elektroden Ei und E2, die miteinander einen Winkel von 900 bilden. Nicht regelbar ist die Elektrode E, die mit den Elektroden Ei und E2 je einen Winkel von 1350 bildet.
Geringe Abweichungen der Winkelgrössen, sowie der Lage der Elektroden in einer Ebene sind zulässig.
PATENT-ANSPRÜCHE :
1. Elektrodenanordnung für elektrische Schmelzöfen, welche mittels dreier in einer Ebene gelegener Lichtbogenelektroden mit Drehstrom gespeist werden, dadurch gekennzeichnet, dass zwei Elektroden zueinander unter einem Winkel von 60 und jede von diesen zu der dritten Elektrode unter einem Winkel von 150 angeordnet sind, so dass entsprechend der gleichen Elektrodenentfernung [zur Erzielung gleicher Belastung der drei Phasen] nur die beiden, einen Winkel von 600 einschliessenden Elektroden regelbar zu sein brauchen.

Electrode arrangement for electrical melting furnaces.
In the previous electrode arrangements for multi-phase alternating current, the electrodes tend to be offset from one another by 1200 or 2 x 900. To achieve approximately the same phase load, all three electrodes are regulated, which means that either higher operating costs or three automatic regulators are required.
The present invention saves one of the regulations. According to the invention, two electrodes are arranged at an angle of 600 to one another and each of these to the third electrode at an angle of 1500 for three-phase current. In the case of concatenated two-phase alternating current, two electrodes are arranged at an angle of 90 to one another and each of these electrodes are arranged at an angle of 1350 to the third electrode.
In the drawing, these two electrode arrangements for melting furnaces are shown schematically.
The arrangement according to FIG. 1 applies to three-phase current. The electrode E does not need to be adjustable.
EMI1.1
Enclose electrode E at an angle of 1500.
The arrangement according to FIG. 2 applies to concatenated two-phase current. Only the two electrodes Ei and E2, which form an angle of 900 with one another, can be regulated. Electrode E, which forms an angle of 1350 with electrodes Ei and E2, cannot be regulated.
Slight deviations in the angular dimensions and the position of the electrodes in a plane are permitted.
PATENT CLAIMS:
1. Electrode arrangement for electric melting furnaces which are fed with three-phase current by means of three arc electrodes located in one plane, characterized in that two electrodes are arranged at an angle of 60 to one another and each of these to the third electrode at an angle of 150, so that corresponding to the same electrode distance [to achieve the same load on the three phases] only the two electrodes, which enclose an angle of 600, need to be adjustable.
