Description
Löschkammer für Ölschalter Die Erfindung bezieht sich auf Löschkammern für Hochspannungsrilschalter. Bisher ist es allgemein üblich gewesen, die Uschkammer als ein in sich starres Gebilde herzustellen. In Abweichung hiervon wird nach der Erfindung die Ausbildung der Löschkaminer so gewählt, daß sie ihr Volumen beim Auftreten der Explosionsdrücke im Falle eines Abschaltvorganges vergrößern kann, wobei jedoch die Energie einer Feder überwunden werden muß. Auf diese Weise wird vermieden, daß die plötzlich entstehenden Drücke schlagartig die Löschkammer beanspruchen. Die Auswirkung der Explosion erfährt vielmehr eine Dämpfung, wobei gleichzeitig ein Teil der den Gasen. .imnewohnenden Energie verbraucht wird zur Leistung der Arbeit, welche nötig ist, um die Feder vollständig zusammenzudrücken, welche die Volumenvergrößerung des Löschkammerraumes zuläßt.Arcing Chamber for Oil Switches The invention relates to arcing chambers for high-voltage rail switches. So far it has been common practice to use the Ushkammer than to produce an inherently rigid structure. In deviation from this, according to the Invention, the design of the fire chimney chosen so that it increases its volume when it occurs the explosion pressures can increase in the event of a shutdown, but the energy of a spring has to be overcome. In this way it is avoided that the suddenly arising pressures suddenly stress the extinguishing chamber. the Rather, the effect of the explosion is dampened, with a simultaneous Part of the gases. . energy is consumed in the home for the performance of work, which is necessary to compress the spring completely, which increases the volume of the extinguishing chamber space.
Ein entsprechendes Ausführungsbeispiel zeigt die Zeichnung. In dieser bezeichnet a die Durchführung, an welcher der Löschkammerdeckel b befestigt ist, der seinerseits ein Mantelstück c trägt, welches eine derartige Querschnittform besitzt, daß in ihm die Feder d untergebracht werden- kann. Das Mantelstück c dient weiterhin als Führung für das metallische Zylinderstück e, welches seinerseits den aus Isoliermaterial bestehenden Löschkammerzylinder f trägt, in dessen unterem Ende der Löschkammerboden g eingesetzt-ist. h bezeichnet den . in der Löschkammer angeordneten Hauptkontakt.A corresponding embodiment is shown in the drawing. In this a denotes the bushing to which the arcing chamber cover b is attached, which in turn carries a jacket piece c which has such a cross-sectional shape possesses that the spring d can be accommodated in it. The shell piece c is used continue as a guide for the metallic cylinder piece e, which in turn the made of insulating material extinguishing chamber cylinder f carries in its lower end the arcing chamber floor g is inserted. h denotes the. arranged in the quenching chamber Main contact.
Beim Abschaltvorgang wird zufolge der auftretenden Gasdrücke, die auf den Löschkammerboden wirken, der aus den Stücken e, f, g bestehende Löschkammerteil unter Überwindung der Spannung der Feder d nach unten ausweichen, so daß sich auf diese Weise eine Dämpfung der stoßartigen Beanspruchung der Löschkammer ergibt.During the shutdown process, according to the gas pressures that occur act on the arcing chamber floor, the extinguishing chamber part consisting of pieces e, f, g while overcoming the tension of the spring d dodge downwards, so that on this results in a damping of the shock-like stress on the arcing chamber.
