Verfahren zur Steuerung eines Gleichstromes mittels eines Metalldampfapparates, Patentiert im Deutschen Reiche vom 9, September 1922 ab. Method for controlling a direct current by means of a metal steam apparatus, patented in the German Reich on September 9, 1922.

Die Erfindung überträgt den Grundgedanken der elektrostatischen Beeinflussung eines Stromes, wie er in der Elektronenröhre verwirklicht ist, auf den Strom des Quecksilberlichtbogens. The invention transfers the basic idea of the electrostatic influence of a Current, as it is realized in the electron tube, to the current of the mercury arc.

In der Abbildung ist das Schema einer Anlage zur Steuerung eines Quecksilberlichtbogens in einem Ausführungsbeispiel dargestellt. Es ist G das Vakuumgefäß, A die Anj ode, Q die Quecksilberkathode mit einem ; durch die Hilfsanode// um erhaltenen Katho- \ denfleck, LC ein dem Quecksilberlichtbogen ί parallel geschalteter Schwingungskreis, der I das Potential des Gitters S durch T2 beeinflußt, G1 ein Verbrauchsapparat, T1 ein Transformator, i dessen Primärspule.The figure shows the scheme of a system for controlling a mercury arc in one embodiment. It is G the vacuum vessel, A the anode, Q the mercury cathode with one; through the auxiliary anode // to the obtained cathode \ denfleck, LC a mercury arc ί in parallel oscillating circuit, the I influences the potential of the grid S by T 2, G 1 is a consumption apparatus, T 1, a transformer, i whose primary coil.

Nehmen wir an, der Zündbogen zwischen Q und H brenne, das Netz aber sei noch span-Let us assume that the ignition arc between Q and H is burning, but the network is still tensioned.

nungslos. Wird nun das Netz eingeschaltet, so entsteht Spannung zwischen Q und A. Das Gitter hat aber das negative Potential von Q. Infolgedessen enden alle Kraftlinien, die von A ausgehen, auf .dem Gitter, und der Bogen kann nicht einsetzen. ' Das einzige, was geschieht, ist, daß der Kondensator C aufgeladen wird. Die Schaltung der das Gitter beeinflussenden Spule F2 ist so, daß bei diesem ίο Aufladen von C die negative Ladung von V9 verstärkt wird. Nimmt man den Kreis C L ohne wesentlichen Widerstand, so wird C über die Netzspannung hinaus aufgeladen. Damit nicht von dem Augenblick an, wo Konden* ig satorspannung und Netzspannung gleich werden, die Schutzwirkung des Gitters aufgehoben wird, kann man in bekannter Weise dem Gitter eine negative Vorspannung geben. Der Aufladung des Kondensators über die Netzspannung Linaus folgt ein Rückstrom. Da bei wird dann durch die Kupplung zwischen L und F2 das Potential des Gitters positiv, so daß jetzt der Lichtbogen einsetzt, wodurch der Kondensator entladen wird. Eine Selbstinduktion in der Zuleitung, die im Verbrauchsapparat G1 liegen kann, hat, wie durch Barkhausen bekannt geworden ist., die Wirkung, daß der Lichtbogen zwischen Q und A bei entsprechender Bemessung der Elemente des Schwingungskreises und der vorgeschalteten Selbstinduktion abreißt, Der nun weiter noch durch die Selbstinduktion hindurchgehende Netzstrom dient nur dazu, den Kondensator wieder aufzuladen. Dabei wird dann aber, wie beim ersten Aufladen, das Gitterpotential negativ und verhindert wiederum, wie oben, das Einsetzen des Lichtbogens, Mit der dann beginnenden Überladung des Kondensators wiederholt sich das vorstehend beschriebene Spiel.impotent. If the mains is now switched on, voltage arises between Q and A. However, the grid has the negative potential of Q. As a result, all lines of force emanating from A end on the grid, and the arc cannot begin. 'The only thing that happens is that the capacitor C is charged. The circuit of the lattice-influencing coil F 2 is such that in this ίο charging of the negative charge of C V is amplified. 9 If the circuit CL is taken without any significant resistance, then C is charged beyond the mains voltage. So that the protective effect of the grid is not canceled from the moment when the capacitor voltage and the mains voltage become the same, the grid can be given a negative bias voltage in a known manner. The charging of the capacitor via the line voltage Linaus is followed by a reverse current. Since the potential of the grid is then positive through the coupling between L and F 2 , so that now the arc begins, whereby the capacitor is discharged. As has become known from Barkhausen, a self-induction in the supply line, which can be located in the appliance G 1 , has the effect that the arc between Q and A breaks when the elements of the oscillation circuit and the upstream self-induction are appropriately dimensioned Mains current still passing through the self-induction only serves to recharge the capacitor. In this case, however, as with the first charging, the grid potential becomes negative and again prevents the onset of the arc, as above. With the overcharging of the capacitor that then begins, the above-described game is repeated.

Dadurch, daß der Bogen nicht brennt, wenn der Kondensator sich auflädt, ist dieser imstande, sich hoch aufzuladen, ohne dabei durch einen einsetzenden Lichtbogen gestört zu werden. Infolgedessen entstehen kräftige Schwingungen. Die Rolle des Gitters besteht demnach darin, daß unter seinem Schutz der Kondensator sich ungestört aufladen kann.Because the arc does not burn when the capacitor is charging, it is able to to charge up without being disturbed by an incipient arc. As a result, strong vibrations arise. The role of the grid therefore exists that under its protection the capacitor can charge itself undisturbed.

Die auf diese Weise entstandenen Schwingungen können nun folgendermaßen geregelt werden: Der Bogen setzt, wie soeben dargestellt, in dem Moment ein, wo der Kondensator C anfängt, sich zu entladen. Würde in dem Augenblick, wo der Kondensator vollständig aufgeladen ist, das Gitter auch noch weiter negativ bleiben, so könnte der Bogen nicht einsetzen und damit eine Entladung des Kondensators über den Lichtbogen nicht stattfinden. Es tritt somit eine Stauung der Energie ein, bis das Gitterpotential durch Positivwerden der Energie den Weg über den Bogen freigibt.The vibrations created in this way can now be regulated as follows be: The arc starts, as just shown, at the moment when the capacitor C begins to discharge. Would at the moment when the capacitor is complete is charged, the grid remains negative, so the arc could do not use and thus a discharge of the capacitor via the arc does not take place. There is thus a build-up of energy until the grid potential becomes positive the energy releases the path over the arch.

Die Regelung dieses Zeitpunktes kann etwa so geschehen, daß man in der bekannten Weise die Vorspannung des Gitters, z. B. über den Transformator T1, ändert.The regulation of this point in time can be done in such a way that the bias of the grid, for. B. via the transformer T 1 changes.
