    Metalldampfgleichrichteranlage.   



   Das Stammpatent betrifft u. a. eine   Metalldampfgleiehrichteranlage   mit den Lichtbogen steuernden
Körpern (Gitter, Hülsen) mit mehreren Hauptanoden und im Wege des Lichtbogens zwischen jeder
Hauptanode und der ständig erregten Kathode angeordnetem, zeitweise durch negatives Potential sperrendem Steuerorgan und je einer oder mehreren an positiven Spannungen zu legenden Hilfsanoden. 



  Die Erfindung betrifft vereinfachte Anordnungen dieser Art, bei denen die   Hilfserregeranoden   weder ständig eingeschaltet noch zu veränderlichen Zeiten gezündet werden müssen. Nach der Erfindung brennen die Hilfserregeranoden in jeder Periode nur zeitweise, aber mindestens während derjenigen
Zeit, innerhalb welcher der   Zündzeitpunkt   der zugehörigen Entladungsbahnen verschoben werden kann. 



   Auch hier wird der Vorteil erreicht, dass die Zündbedingungen der einzeln gesteuerten Hauptanoden des mehrphasigen Metalldampfgleichrichters einander angeglichen und dem Einfluss der mit der Belastungsstromstärke wechselnden Ionisation im Gefäss   entrüekt   werden. Jeder Hauptanode ist vorteilhaft mindestens je eine Hilfserregeranode unmittelbar zugeteilt. Es können aber auch mehrere
Hauptanoden gemeinsam eine Hilfserregeranode besitzen, die wegen ähnlichen Verhaltens, z. B. wenn sie an derselben Spannung liegen oder mit geringen   Phasenabstände   zeitlich nacheinander zünden, sich zu einer Gruppe zusammenfassen lassen. Die Hilfsanoden werden vorteilhaft mit Gleichstrom gespeist.

   Man kann die Hilfserregeranoden auch mit Wechselstrom speisen und Mittel vorsehen, welche die Brennzeit der   Erregerlichtbögen   verlängern und deren Kurvenform rechteckig gestalten. Ausser oder an Stelle einer Glättungsdrossel können im Gleichstromkreis der   Hi1fserregung   auch Drosseln in gemeinsamen Punkten von je zwei oder mehreren Anodenkreisen der Hilfserregung angeordnet sein. 



   Je zwei oder mehrere Anodenkreise der Hilfserregung können vorteilhaft auch transformatorisch ge- gekoppelt sein. 



   In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schaltbild dargestellt. Der Gleich- richter 1 hat eine Kathode   2,   die an die Leitung 3 angeschlossen ist. Die Hauptanoden des Gleichrichters sind mit 4,5, 6,7, 8 und 9 bezeichnet. In der Nähe jeder Hauptanode liegt je eine Hilfsanode. Die Hilfs-

Der Erregertransformator 22 wird aus dem Wechselstromnetz 27 gespeist.

    Metal vapor rectifier system.



   The parent patent concerns u. a. controlling a metal vapor rectifier system with the arc
Bodies (grids, sleeves) with several main anodes and by way of the arc between each
Main anode and the constantly excited cathode arranged, temporarily blocking by negative potential control element and each one or more auxiliary anodes to be connected to positive voltages.



  The invention relates to simplified arrangements of this type in which the auxiliary exciter anodes do not have to be switched on constantly or ignited at variable times. According to the invention, the auxiliary exciter anodes burn only temporarily in each period, but at least during that period
Time within which the ignition point of the associated discharge paths can be shifted.



   Here, too, the advantage is achieved that the ignition conditions of the individually controlled main anodes of the multiphase metal vapor rectifier are adjusted to one another and the influence of the ionization in the vessel, which changes with the load current, is eliminated. Each main anode is advantageously assigned at least one auxiliary exciter anode. But there can also be several
Main anodes together have an auxiliary exciter anode, which because of similar behavior, e.g. B. If they are connected to the same voltage or ignite one after the other with small phase differences, they can be combined into a group. The auxiliary anodes are advantageously fed with direct current.

   The auxiliary exciter anodes can also be fed with alternating current and means can be provided which extend the burning time of the excitation arcs and make their curve shape rectangular. In addition to or instead of a smoothing choke, chokes can also be arranged in the direct current circuit of the auxiliary excitation at common points of two or more anode circuits of the auxiliary excitation.



   Two or more anode circuits of the auxiliary excitation can also advantageously be coupled in a transformer.



   In the drawing, an embodiment of the invention is shown in the circuit diagram. The rectifier 1 has a cathode 2 which is connected to the line 3. The main anodes of the rectifier are labeled 4.5, 6.7, 8 and 9. An auxiliary anode is located near each main anode. The auxiliary
 EMI1.1
 winding of the excitation transformer 22 connected, u. between the exciter anodes 10 and 13, 11 and 14 as well as 12 and 15 are each connected to a secondary coil, the zero point of which is connected to the line J via smoothing chokes 23, 24, 25 and 26. The excitation transformer 22 is fed from the alternating current network 27.
