Description

Schalter mit Lichtbogenlöschung durch strömendes Druckgas Die Erfindung betrifft eine weitere Ausbildung des Schalters mit Lichtbogenlöschung durch strömendes Druckgas nach Patent 621 518. Nach der Erfindung sind die Widerstände, die eine feste Hilfselektrode oder mehrere solche Hilfselektroden mit einem der Schalterkontakte verbinden, durch Kondensatoren ersetzt.Switch with arc quenching by flowing compressed gas The invention relates to a further design of the switch with arc quenching by flowing Compressed gas according to patent 621 518. According to the invention, the resistors are one fixed auxiliary electrode or several such auxiliary electrodes with one of the switch contacts connect, replaced by capacitors.

Bei bekannten Schaltern, die Kondensatoren zwecks Verlangsamung der Spannungserhöhung nach dem Abreißen des Lichtbogens aufweisen, sind die Kondensatoren parallel an die Kontakte angeschaltet. Da die Kapazität bei diesen Anordnungen nach dem Erlöschen des Lichtbogens zwischen den Kontakten eingeschaltet verbleibt, ist es notwendig, zur Unterbrechung des Kapazitätsstromes einen besonders bemessenen Trennschalter hinzuzufügen.In known switches, the capacitors in order to slow down the The capacitors are responsible for the voltage increase after the arc has broken off connected in parallel to the contacts. Since the capacity with these arrangements according to remains switched on after the arc has been extinguished between the contacts it is necessary to use a specially dimensioned one to interrupt the capacitance current Add disconnector.

Bei dem Schalter nach der Erfindung werden einerseits gegenüber dem Schalter nach dem Hauptpatent die Vorzüge ausgenutzt, die in der Anwendung von Kondensatoren an Stelle von Widerständen liegen, in vorliegendem Falle insbesondere der Vorteil, daß die Unterbrechung des Stromes durch die Herabsetzung der Eigenfrequenz erleichtert wird. Andererseits hat die Anwendung der Kondensatoren nach der Erfindung gegenüber der obenerwähnten bekannten Anwendung von Kondensatoren bei Schaltern den Vorteil, daß der Kondensator mit dem Erlöschen des Lichtbogens abgeschaltet wird und demgemäß ein besonderer Trennschalter für das Abschalten des Kondensators nicht erforderlich ist. Die Kondensatoren werden bei der Anordnung nach der Erfindung durch den Lichtbogen selbst in den Stromkreis eingefügt, und ihr Stromkreis Zvird geöffnet, sobald der Lichtbogen erloschen ist.In the switch according to the invention on the one hand compared to the Switches according to the main patent take advantage of the advantages in the use of capacitors instead of resistors, in the present case in particular the advantage that the interruption of the current is facilitated by the lowering of the natural frequency will. On the other hand, the use of the capacitors according to the invention has opposite the above-mentioned known use of capacitors in switches has the advantage of that the capacitor is switched off with the extinguishing of the arc and accordingly a special disconnector for switching off the capacitor is not required is. The capacitors are in the arrangement according to the invention by the arc itself inserted into the circuit, and your circuit Zv is opened as soon as the Arc is extinguished.

Man kann auch die gemäß dem Hauptpatent vorgesehenen Widerstände beibehalten, sie aber parallel mit Kondensatoren schalten, die einerseits an die Hilfselektrode und andererseits an den einen der Kontakte angeschlossen sind. Dadurch werden folgende Vorteile erzielt: Erstens gestattet die Anordnung, bei einem Schalter mit gegebener Abschaltleistung den Ohmschen Wert des Widerstandes zu erhöhen. Die Erhöhung des Widerstandswertes erleichtert das Unterbrechen des durch die Einschaltung dieses Widerstandes verminderten Stromes. Der Widerstand mit einem erheblicherem Ohmschen Wert kann eine verhältnismäßig verkleinerte Raumausdehnung und verringerten Gestehungspreis besitzen.The resistances provided for in the main patent can also be retained, but they connect in parallel with capacitors, which are connected to the auxiliary electrode on the one hand and on the other hand are connected to one of the contacts. This results in the following Advantages achieved: First, the arrangement allows for a switch with a given Breaking capacity to increase the ohmic value of the resistor. The increase in the Resistance value makes it easier to interrupt the by switching it on Resistance to reduced current. The resistance with a more significant ohmic Value can be a relatively reduced space and a reduced cost price own.

Zweitens ist der Vorteil vorhanden, daß der Schalter, wenn die Kapazität durch einen Widerstand nebengeschlossen. ist, keine Stö- rungen in dem unterbrochenen Stromkreis hervorrufen kann, 'weil die Spannung in kek' nem Zeitpunkt plötzliche Änderungen info1 der Gegemvart des Widerstandes im Strö kreis erfährt. Schließlich werden auch durcl§ü das Vorhandensein einer Kapazität und eines Widerstandes, die parallel geschaltet sind, die- Schwingungen infolge der Wiederherstelluhk der Spannung nach der Stromunterbrechung gedämpft. Second, there is the advantage that the switch when the capacity is through one Shunted resistance. is, no disturbance in the interrupted circuit cause 'because the tension in kek' Sudden changes at a point in time info1 the opposite of the resistance in the stream circle learns. Finally, also through the presence of a capacity and one Resistor, which are connected in parallel, the- Vibrations as a result of the restoration the voltage after the power interruption muffled.
