Description
Beim. Abschalten von Kurzschlüssen mittels ölschalter tritt häufig eine sehr starke Entwicklung von Öldämpfen im Schalter auf, die, um einer Explosion des Schalters vorzubeugen, abgeleitet werden müssen. Bei den seitherigen Schaltern war die Anordnung so getroffen, daß die auf dem Schalterdeckel sitzende ölklappe durch den inneren Überdruck geöffnet wurde, um den öldämpfen den Austritt ins Freie zuAt the. Switching off short circuits by means of an oil switch is often a very strong development from oil vapors in the switch, which are derived to prevent the switch from exploding Need to become. In the case of the switches since then, the arrangement was such that the oil flap on the switch cover was opened by the internal overpressure, to prevent the oil vapors from escaping into the open air
to gestatten. Die heißen Öldämpfe kommen hier direkt mit den außenliegenden spannungsführenden Teilen in Berührung, und eine Entzündung derselben durch einen Überschlag nach dem Schalterdeckel und damit eine Explosion des Schalters lag sehr nahe. Diese Gefahr ist bei vorstehender Neuerung dadurch beseitigt worden, daß die öldämpfe an einer von den außer öl liegenden spannungsführenden Teilen entfernt gelegenen Stelle ins Freie treten, derart, daß an geeigneten Stellen des öltopfes, z. B., wie in der Abbildung dargestellt, in den Ecken des Topfes, Rohre α angeordnet sind, die durch den Boden des Ölbehälters b ins Freie gehen, so daß die öldämpfe unten am öltopf heraustreten.to allow. The hot oil vapors come into direct contact with the external live parts, and ignition of the same due to a flashover to the switch cover and thus an explosion of the switch was very likely. This risk has been eliminated in the above innovation in that the oil vapors enter the open air at a location remote from the live parts outside of the oil. B., as shown in the figure, in the corners of the pot, tubes α are arranged, which go through the bottom of the oil container b into the open, so that the oil vapors emerge at the bottom of the oil pot.
