Description
Vorrichtung zum schnellen Löschen des Unterbrechungslichtbogens an Hochspannungsluftschaltern Es sind bereits Vorrichtungen für Hochspannungsluftschalter zum schnellen Löschen des Unterbrechungslichtbogens bekannt, die auf elektrodynamischer Wirkung beruhen und den Lichtbogen durch Anordnung eines magnetischen Blasfeldes zum Erlöschen bringen. Hierbei hat man bereits vorgeschlagen, durch Anordnung von Querwänden in der Funkenkammer den Lichtbogen in mehrere Teile zu zerlegen, um den Abschaltvorgang noch weiter zu beschleunigen. Dem gleichen Zweck dient eine bekannte Einrichtung, bei der in der Querrichtung der Funkenkammer nebeneinanderliegende Metallstäbe eingebaut sind.Device for quickly extinguishing the interrupting arc High voltage air switches There are already devices for high voltage air switches known for quickly extinguishing the interruption arc, which is based on electrodynamic Effect based and the arc through the arrangement of a magnetic blown field extinguish. It has already been proposed by the arrangement of Transverse walls in the spark chamber split the arc into several parts in order to reduce the To accelerate the shutdown process even further. A well-known one serves the same purpose Device in which in the transverse direction of the spark chamber are adjacent Metal rods are built in.
Diese Anordnung wird gemäß der Erfindung dadurch verbessert, daß in den Funkenkammern in mehreren Reihen übereinander zahlreiche metallische Bolzen. angeordnet sind, mit denen der Lichtbogen beim Hochsteigen nach und nach in Berührung gelangt. Hierdurch wird erreicht, daß einmal der Lichtbogen stark abgekühlt wird und daß die Energie in ihm äußerst schnell abnimmt, so daß er weit schneller als bei den bekannten Vorrichtungen zum Abreißen gebracht wird.This arrangement is improved according to the invention in that in the spark chambers in several rows, one on top of the other, with numerous metallic bolts. are arranged with which the arc gradually comes into contact when climbing got. This ensures that the arc is once strongly cooled and that the energy in it decreases extremely quickly, so that it is far faster than is made to tear off in the known devices.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Abb. i zeigt eine Seitenansicht der neuen Anordnung, während in Abb. 2 ein Querschnitt durch die Funkenkammer dargestellt ist.An exemplary embodiment of the invention is shown in the drawing. Fig. I shows a side view of the new arrangement, while in Fig. 2 a cross section is represented by the spark chamber.
In Abb. i dient der Schalter io zur Unterbrechung des zwischen den Leitungen i i und 12 fließenden Stromes. Der bewegliche Teil des Schalters besitzt in an sich bekannter Weise einen Hauptkontakt 13 und zwei übereinander angeordnete Abreißkontakte 14 und 15, auf die der Lichtbogen beim öffnen des Schalters der Reihe nach überspringt. Die oberhalb der Schalterkontakte angeordnete Funkenkammer besteht aus zwei durch einen Luftraum in der Mitte getrennten Teilen 16 und 17, In jedem Teil der Funkenkammer ist eine Reihe von hintereinander geschalteten Blasspulen 18 bzw. i9 angeordnet, die mit je einem Schalterpol verbunden sind, so daß, wenn die Fußpunkte des Abschaltlichtbogens auseinander wandern, sämtliche Blasspulen der Reihe nach in den Lichtbogenweg eingeschaltet werden. In die Lichtbogenkammer sind zur Unterteilung und zur Abkühlung des Lichtbogens eine Anzahl kleiner Kupferbolzen 2o eingesetzt. Die Seitenwände der Lichtbogenkammern sind mit doppelten Wandungen 2i, 2ia und 2:2,:22a ausgeführt. Die Kupferbolzen 2o werden in Bohrungen der Innenwandungen 2i und 22 gehalten und am Herausfallen durch die Außenwandungen Zia und 22a, die mit Schrauben 24a und 25a an den Innenwandungen befestigt sind, gehindert. Der innere Abstand der Lichtbogenkammern wird durch Bolzen 23, deren Schrauben 24 und 25 in die inneren Wandungen 2i und 22 eingelassen sind, gewahrt. Diese verteilten Kupferbolzen bewirken eine vielfache Zerteilung des aufsteigenden Lichtbogens und gleichzeitig eine starke Abkühlung desselben. Es wird hierdurch erreicht, daß der Lichtbogen äußerst schnell zum Verlöschen gebracht wird.In Fig. I, the switch io is used to interrupt the current flowing between the lines ii and 12. The movable part of the switch has, in a manner known per se, a main contact 13 and two tear-off contacts 14 and 15 arranged one above the other, onto which the arc jumps one after the other when the switch is opened. The spark chamber arranged above the switch contacts consists of two parts 16 and 17 separated by an air space in the middle. when the base points of the cut-off arc move apart, all blow coils are switched on in sequence in the arc path. A number of small copper bolts 2o are inserted into the arc chamber to subdivide and cool the arc. The side walls of the arc chambers are designed with double walls 2i, 2ia and 2: 2,: 22a. The copper bolts 2o are held in bores in the inner walls 2i and 22 and are prevented from falling out by the outer walls Zia and 22a, which are fastened to the inner walls with screws 24a and 25a. The inner distance between the arc chambers is maintained by bolts 23, the screws 24 and 25 of which are let into the inner walls 2i and 22. These distributed copper bolts cause the rising arc to be broken up multiple times and, at the same time, to cool it down considerably. It is thereby achieved that the arc is extinguished extremely quickly.
