Description

Es ist bekannt, Vakuumventile, insbesondere Quecksilberdampf ventile, als Schalter zu verwenden, indem der abzuschaltende Strom den Lichtbogen des Ventils speist und durch einen entgegengesetzt gerichteten Stromstoß gelöscht wird. Vorliegende Erfindung besteht in der Anwendung einer sehr einfachen Schaltung zur Erreichung des an sich bekannten Zieles.It is known to use vacuum valves, especially mercury vapor valves, as switches use in that the current to be switched off feeds the arc of the valve and through an opposing current surge is extinguished. The present invention exists in the use of a very simple circuit to achieve what is known per se Target.

to Die Abbildung stellt schematisch ein Ausführungsbeispiel des Erfindungsgegenstandes dar.to The figure shows schematically an embodiment of the subject of the invention represent.

Die Leitung 2-2 führt in der angegebenen Pfeilrichtung den zu unterbrechenden Gleichstrom. Das Vakuumventil r ist beispielsweise ein Quecksilberdampfkolben. Die Sekundärwicklung S eines Transformators 3, ein Kondensator 6 und ein Dämpfungswiderstand 15 sind in Reihe geschaltet und über den Licht-Line 2-2 carries the direct current to be interrupted in the direction of the arrow. The vacuum valve r is, for example, a mercury vapor flask. The secondary winding S of a transformer 3, a capacitor 6 and a damping resistor 15 are connected in series and via the light

äo bogen des Vakuumventils 1 zu einem Schwingungskreis geschlossen. .äo arc of the vacuum valve 1 to an oscillation circuit closed. .

Der ganze zu unterbrechende Hauptstrom oder bei Shuntung der Primärwicklung mindestens an Teil dieses Stromes fließt durch die Primärwicklung des Transformators 3. Bei raschem Anstieg des Hauptstromes werden im Schwingungskreis S, 6, 15, 1 Schwingungen erzeugt, die sich im Vakuumventil 1 dem Hauptstrom überlagern. Ist die Amplitude der Schwingung so groß, daß sich der resultierende Lichtbogenstrom momentan dem Werte Null nähert, so erlischt der Lichtbogen. The entire main current to be interrupted or, if the primary winding is shunted, at least Part of this current flows through the primary winding of the transformer 3. If the main current rises rapidly, the oscillation circuit S, 6, 15, 1 will oscillate generated, which are superimposed on the main flow in the vacuum valve 1. If the amplitude of the oscillation is so great that the If the resulting arc current momentarily approaches zero, the arc is extinguished.
