Description

Die Erfindung bezieht sich auf Ölschalter höherer Spannung und großer Stromstärken. Bei solchen Ülschaltern tritt bekanntlich die Schwierigkeit auf, einerseits eine ausreichende Isolation zu erreichen, anderseits die Wärmeentwicklung auf ein erträgliches Maß herabzusetzen. Dies wird gemäß der Erfindung, die sich auf einpolige Schalter bezieht, bei denen eine " vier-, acht- oder mehrfacheThe invention relates to higher voltage and high current oil switches. It is well known that such Ülschalters encounter the problem of, on the one hand, an adequate one To achieve isolation, on the other hand, to reduce the heat development to a tolerable level. This is according to the invention, which relates to single pole switches, in which a "four, eight or multiple

ίο Unterbrechung angewendet wird, dadurch erreicht, daß die Durchführungen und inneren Leitungsträger f, g bzw. h, i, k, I1 m, n an Eisen c, d, e befestigt sind, die nicht parallel zu den Bürsten, sondern senkrecht zu diesen, also in der Längsrichtung, liegen, und ferner dadurch, daß die Durchführungen bzw. die Verbindungen ο, ρ, q zu den Leitungsträgern in der gleichen Richtung wie die Eisenträger c, d, e angeordnet sind. Es können somit keine Wirbelströme im Eisen auftreten, die ja bekanntlich die Hauptursache für schädliche Wärmewirkungen bilden. Ferner wird dadurch erreicht, daß die Ein- und Ausführungen des Stromes in großer Entfernung voneinander zu liegen kommen.ίο interruption is applied, achieved in that the bushings and inner lead frames f, g and h, i, k, I 1 m, n are attached to iron c, d, e , which are not parallel to the brushes, but perpendicular to them these, so in the longitudinal direction, are, and further in that the bushings or the connections ο, ρ, q to the line supports are arranged in the same direction as the iron supports c, d, e. No eddy currents can occur in the iron, which are known to be the main cause of harmful heat effects. It is also achieved in this way that the inlet and outlet of the current come to lie at a great distance from one another.

Ein Beispiel dieser Anordnung ist in der Zeichnung dargestellt, und zwar ein Schalter mit vier Bürsten, also achtfacher Unterbrechung. Der Schalteraufbau erfolgt dabei so, daß zwei seitliche Wangen α und h die 3c Längsträger c, d und e tragen. An diesen sind die Durchführungen / und g sowie die Zwischenstützen h, i, k, I1 m und η befestigt. Zwischen / und g bzw. h und i befinden sich keine Eisenteile,, ebensowenig zwischen k, i 3i und m, n. Die Wirbelstrombildung und damit die Erwärmung im Deckel wird also auf das geringst mögliche Maß herabgesetzt.An example of this arrangement is shown in the drawing, namely a switch with four brushes, that is, eight-fold interruption. The switch is constructed in such a way that two lateral cheeks α and h support the 3c longitudinal members c, d and e . The bushings / and g and the intermediate supports h, i, k, I 1 m and η are attached to these. There are no iron parts between / and g or h and i , just as little between k, i 3i and m, n. The formation of eddy currents and thus the heating in the cover is reduced to the lowest possible level.
