Description

Die Erfindung bezieht sich auf Lichtbogen- und Glühkathodengleichrichter bzw. Metalldampfgleichrichter mit den Anoden zugeordneten, zwecks Regelung der abgegebenen Gleichstromleistung elektrisch gesteuerten Gittern. Um den Wert und die Dauer des vom Gleichrichter gelieferten Gleichstromes regeln zu können, ist bereits vorgeschlagen, die Phase der Spannungen an der Anode und dem Steuergitter gegeneinander zu verschieben. Zu diesem Zweck sind Phasenschieber und besondere Spannungstransformatoren im Gitterstromkreis erforderlich, wodurch die Einrichtung kompliziert und teuer wird.The invention relates to arc and hot cathode rectifiers or metal vapor rectifiers with the anodes associated, electrically controlled for the purpose of regulating the output direct current power Bars. About the value and duration of the direct current supplied by the rectifier to be able to regulate, has already been proposed, the phase of the voltages at the anode and to move the control grid against each other. Phase shifters are used for this purpose and special voltage transformers are required in the grid circuit, whereby the Setup becomes complicated and expensive.

Gemäß der Erfindung wird der gleiche Zweck in einfacherer Weise dadurch erreicht, daß die Steuergitter über Glimmröhren mit den Anoden verbunden werden. Die Dauer und der Wert des gelieferten Gleichstromes wird durch Verstellung des Zündmomentes der Glimmröhre geregelt. In Reihe mit der Glimmröhre kann vorteilhaft eine veränderliche Gleich- oder Wechselspannung als Zusatzspannung geschaltet sein, die mechanisch oder von einer elektrischen Größe beeinflußt wird. Die Einrichtung gemäß der Erfindung ist besonders brauchbar bei einer Gitteranordnung, bei der die Sperrwirkung des Gitters so groß ist, daß bei offenem Gitterkreis die Entstehung eines Lichtbogens zwischen Anode und Kathode verhindert ist. Erreicht nun bei brennender Zündanode das Potential zwischen Anode und Gitter den Wert der Durchbruchsspannung der Glimmröhre, so wird das Gitter von der Anode her positiv aufgeladen und .der Lichtbogen zur Kathode gezündet. Durch Verändern des Wertes der Zusatzspannung kann der Zündmoment der Glimmröhre und damit das Einsetzen des Lichtbogens verändert werden.According to the invention, the same purpose is achieved in a simpler way by that the control grids are connected to the anodes via glow tubes. The duration and the value of the supplied direct current is determined by adjusting the ignition torque the glow tube regulated. In series with the glow tube can advantageously be a variable Direct or alternating voltage can be connected as an additional voltage, which is influenced mechanically or by an electrical variable will. The device according to the invention is particularly useful in a grid arrangement, in which the blocking effect of the grid is so great that when the grid circle is open, an arc is created between Anode and cathode is prevented. Now reaches the potential when the ignition anode is burning the value of the breakdown voltage of the glow tube between the anode and the grid, the grid becomes positive from the anode charged and .the arc to the cathode ignited. By changing the value of the Additional voltage, the ignition moment of the glow tube and thus the onset of the arc can be changed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung unter Verwendung eines Gleichrichters mit in der beschriebenen Weise gesteuerten Gittern für die Regulierung eines mit dem Gleichrichterstrom gespeisten Motors dargestellt.In the drawing is an embodiment of the invention using a Rectifier with grids controlled in the manner described for the regulation of a shown with the rectifier current fed motor.

In der Abbildung bedeutet α das Gleichrichtergehäuse mit Kathode b, Zündanode c und den Arbeitsanoden d. Den Anoden zugeordnet sind die Gitter e. Die Anoden werden aus dem Transformator / gespeist. Zwischen dem Sternpunkt der Sekundärwicklung des Speisetransformators und der Kathode liegt der Anker des Gleichstrommotors g. Die Gitter e sind mit den Anoden d über die Glimmröhren H1, h2 verbunden. In Reihe mit den Glimmröhren liegen die Gitterwiderstände iv i2 sowie entweder die Batterie k oder der Transformator m, der primär an das Wechselstromnetz angeschlossen ist.In the figure, α means the rectifier housing with cathode b, ignition anode c and working anodes d. The grids e are assigned to the anodes. The anodes are fed from the transformer /. The armature of the direct current motor g is located between the star point of the secondary winding of the supply transformer and the cathode. The grids e are connected to the anodes d via the glow tubes H 1 , h 2 . In series with the glow tubes are the grid resistances i v i 2 and either the battery k or the transformer m, which is primarily connected to the alternating current network.

Ist der Arbeitslichtbogen zwischen Anode und Kathode durch das Steuergitter gesperrtIs the working arc between anode and cathode blocked by the control grid?

und die Zündanode eingeschaltet, so ist, da das Gitter das Potential der Kathode annimmt, zwischen Anode und Gitter das Transformatorpotential vorhanden. Erreicht dieses Potential den Durchbruchswert der Glimmröhre, so ist der Stromkreis zum Gitter hergestellt und das Gitter an die Anode gelegt. Das Gitter wird infolgedessen positiv aufgeladen und der Lichtbogen zur Kathodeand the ignition anode is switched on, since the grid assumes the potential of the cathode, the transformer potential is present between the anode and the grid. If this potential reaches the breakthrough value of Glow tube, the circuit to the grid is established and the grid is attached to the anode. As a result, the grid is positively charged and the arc to the cathode

ίο kann einsetzen, so daß der Gleichrichterstrom zum Rotor des Gleichstrommotors g fließt. Durch Verändern des positiven oder negativen Wertes der der Batterie k oder dem Transformator m entnommenen Zusatzspan-ίο can start so that the rectifier current flows to the rotor of the DC motor g. By changing the positive or negative value of the additional voltage taken from the battery k or the transformer m

iS nung kann die Zündung der Glimmröhre und damit das Einsetzen des Arbeitslichtbogens des Gleichrichters beschleunigt oder verzögert werden. Dabei kann die Veränderung des Wertes der Zusatzspannung in gewollter Weise mechanisch oder in Abhängigkeit von einer elektrischen Größe aus erfolgen.iS voltage can ignite the glow tube and so that the onset of the rectifier's working arc is accelerated or delayed will. The change in the value of the additional voltage can be intentional mechanically or as a function of an electrical quantity.
