Description

'< Xurzschliessvorrichtung zum gesteuerten Schliessen eines Stromkreises mittels eines Lichtbogens" Das Haupt;patent Nr.P2c57722, Mp.Nr.116/70), bezieht sich auf eine Vorrichtung zum gesteuerten Schliessen eines elektrischen Stromkreises, mittels eines zwischen zwei Elektroden brennenden Lichtbogens. Die Steuerung bewirkt die Bildung eines Lichtbogens zwischen zwei Hilfselektroden in Luft und dieser Lichtbogen wird mittels eines Magnetfeldes zwischen die zwei Hauptelektroden bewegt, so dass die Zündung eines Lichtbogens zwischen ihnen erfolgt, indem eine Schutzeinrichtung der Halbleiter mit äusserst kurzen Zeiten erhalten werden kann. Als Weiterentwicklung der Erfindung ist man dazu gelangt, eine Induktanz in Reihe zur Kurzschliessvorrichtung zu schalten, die dazu bestimmt ist, mit dem tilterkondensator zu schwingen, so dass bei der Polaritätsumkehrung die Halbleiter selbsttätig löschen, Das Arbeiten dieses Stromkreises wird mit Bezug auf die Abbildung beschrieben, in welcher schematisch der einen Filter bevltzende Stromkreis dargestellt wird, welcher Filter aus der Induktanz 1 und dem Kondensator 2, der Induktanz 3 in Reihenschaltung zur Kurzschliesser 4, der Chopper mit Halbleitern 5 besteht, und geeignet ist den Strom in einer Last 6 zu regeln.Short-circuiting device for the controlled closing of a circuit by means of an arc "The main; patent no.P2c57722, Mp.Nr.116/70) on a device for the controlled closing of an electrical circuit, by means of an electric arc burning between two electrodes. The control causes the formation of an arc between two auxiliary electrodes in air and this arc is moved between the two main electrodes by means of a magnetic field, so that the ignition of an arc between them takes place by a protective device the semiconductor can be obtained in extremely short times. As a further development According to the invention, one arrives at an inductance in series with the shorting device to switch, which is intended to oscillate with the filter capacitor, so that when the polarity is reversed, the semiconductors automatically erase, That Working of this circuit is described with reference to the figure in which schematically the circuit covering a filter is shown, which filter from the inductance 1 and the capacitor 2, the inductance 3 in series for Short-circuiter 4, the chopper with semiconductors 5, and suitable is the current in a load 6 to regulate.

Die Wirkungsweise erfolgt in der nachstehenden Weise: Falls ein Fehler eintritt, bewirkt ein Impuls das Zünden des Lichtbogens zwischen den Hauptkontakten der Kurzschlussvorrichtung 4, ,e im hauptpatent beschrieben. Der Kondensator 2 und die Induktanz 3 bilden in dieser Weise einen Schwingkreis und die Spannung den Enden des Kondensators wird umgepolt, so dass die selbst-,uige Löschung des Stromes in den Halbleitern erfolgt. Mit bekannten Hilfsmitteln wird infolgedessen verhindert, dass sie nicht :-enr die Zündimpulse empfangen. Die Halbleiter werden somit gegen Ueberlastungen durch eine Vorrichtung geschützt, die sehr kurze ansprechzeiten besitzt, die unterhalb einer Millisekunde liegen.It works as follows: If there is an error occurs, a pulse causes the arc to be ignited between the main contacts the short circuit device 4,, e described in the main patent. The capacitor 2 and the inductance 3 in this way form a resonant circuit and the voltage at the ends of the capacitor is reversed, so that the self-canceling of the current in the semiconductors takes place. As a result, known aids prevent that they do not: -enr receive the ignition pulses. The semiconductors are thus against Overloads protected by a device that has very short response times, which are less than a millisecond.

Elne weitere Ausbildung der Erfindung besteht in der Reihenschaltung eines Widerstandes mit ungeraden Kennzeichen zur Kurzschliessvorrichtung. Die Vorrichtung arbeitet dann wie folgt: Beim Auftreten einer Ueberspannung erzeugt ein statisches Spannungsrelais durch bekannte Einrichtungen, die Zündung des Lichtbogens zwischen den Hauptkontakten des Kurzschliessers 4 (Fig.2), wie im Hauptpatent beschrieben. Der Widerstand dämpft die Ueberspannung und wird dann durch irgendeine Vorrichtung ausgeschaltet, die auch im Kurzschliesser enthalten sein kann.A further embodiment of the invention consists in the series connection a resistor with an odd number to the shorting device. The device then works as follows: When an overvoltage occurs, it generates a static Voltage relays by known devices, the ignition of the arc between the main contacts of the short circuit 4 (Fig.2), as described in the main patent. The resistor dampens the overvoltage and is then activated by some device switched off, which can also be contained in the short-circuiting device.
