Description

Schnellschalter, bei dem über den den Lichtbogen aufnehmenden normalen Abreißhörnern ein zweites von ihnen getrenntes' Hörnerpaar angeordnet ist Verwendet man in Gleichstromschaltanlagen Schnellschalter, so können bei dem raschen Abschalten Überspannungen eintreten, die die Schaltanlage in Gefahr bringen. Man hat bereits versucht, diese Nachteile durch Verwendung eines zweiten überstromschalters zu beseitigen, der nach Ansprechen des Schnellschalters und Einschalten eines entsprechenden Parallelwiderstandes in den Stromkreis die endgültige Abschaltung bei verringerter Stromstärke übernimmt. Die Erfindung zeigt nun eine Anordnung, bei der ohne einen besonderen Schalter - nur mit einem Schnellschalter - eine gute Abschaltung erreicht wird. Hierbei wird von der bekannten Einrichtung Gebrauch gemacht, bei der über den normalen Abreißhörnern für den Lichtbogen ein zweites Hörnerpaar angebracht ist. Gemäß der Erfindung sind zwischen dem zweiten Hörnerpaar und den Anschlußenden des Schnellschalters Dämpfungswiderstände angeordnet, die die beim Abschalten des Schnellschalters entstehende Überspannung abdrosseln.High-speed switch, with the normal one taking up the arc Tear-off horns a second pair of horns separated from them is used if you have high-speed switches in DC switchgears, you can switch off quickly Overvoltages occur which put the switchgear at risk. One already has tries to eliminate these disadvantages by using a second overcurrent switch, after the high-speed switch has responded and a corresponding parallel resistor has been switched on in the electric circuit takes over the final shutdown at reduced amperage. The invention now shows an arrangement in which, without a special switch - only with a quick switch - a good shutdown is achieved. Here is made use of the known device, in the case of the normal tear-off horns a second pair of horns is attached for the arc. According to the invention are damping resistors between the second pair of horns and the connection ends of the quick switch arranged that the overvoltage that occurs when the high-speed switch is switched off throttle.

Die Abbildung dient zur näheren Erläuterung der Erfindung. über den eigentlichen Schalterkontakten a befinden sich die Hörner b, auf die der Lichtbogen durch die magnetische Blasung überspringt und an denen er abreißen soll. Über den Hörnern b sind zwei auf längere Strecke parallellaufende Hörner c angebracht, die von den ersteren den Lichtbogen übernehmen und nach oben aufsteigen lassen. Zwischen den Enden der Hörner b und der Hörner c sind die Widerstände d, und d2 eingeschaltet, die die Dämpfung des ganzen Schaltvorganges übernehmen.The illustration serves to explain the invention in more detail. on the actual switch contacts a are the horns b on which the arc jumps through the magnetic bubble and where it is supposed to tear off. On the Two horns c running parallel over a longer distance are attached to horns b take over the arc from the former and let it rise upwards. Between at the ends of horns b and horns c the resistors d and d2 are switched on, which take over the damping of the entire switching process.
