Description

Schalter mit Klotz- oder Kugelkontakten haben die Eigenschaft, daß bei großen Strömen mit raschem Stromanstieg die Kontakte abgehoben werden, wobei starker Verschleiß der Kontakte, verbunden mit Überschlägen, und bei Ölschaltern gefährliche Gasentwicklung auftritt. Es ist ferner bekannt, daß nicht nur bei Schaltern mit Kugelkontakten (Punktkontakt), sondern auch bei Schaltern mit Linien- oder Flächenauflage bei einseitiger Auflage der Kontakte durch die in den einzelnen Kontaktstücken zur Berührungsstelle hinlaufenden Stromlinien Stromschleifen gebildet werden (vgl. Fig. 1 beiliegender Zeichnung), die notwendig zum Abheben der Kontakte 1, 2 führen müssen. Besonders nachteilig wirken in dieser Hinsicht die in den Kontaktflächen der Kontakt-Stücke verlaufenden, nahe beieinanderliegenden Stromlinien.Switches with block or ball contacts have the property that with large currents with a rapid rise in current, the contacts are lifted, with heavy wear of the contacts, associated with flashovers, and dangerous gas development in the case of oil switches occurs. It is also known that not only with switches with ball contacts (point contact), but also with switches with line or surface support with one-sided support of the contacts through the in the individual contact pieces to the point of contact Current loops are formed in the direction of streamlines (see FIG. 1 enclosed Drawing), which must lead to lifting contacts 1, 2. Particularly disadvantageous in this respect are those in the contact surfaces of the contact pieces running, closely spaced streamlines.

Es ist bekannt, diese bei den Kugelkontakten bzw. durch einseitiges Aufliegen der Linien- oder Flächenkontakte hervorgerufene Stromschleife möglichst dadurch unwirksamIt is known that this with the ball contacts or by resting on one side of the Line or surface contacts caused current loop as ineffective as possible

as zu machen, daß der Abstand zwischen den nebeneinander verlaufenden Stromlinien künstlich vergrößert wird. Gemäß der Erfindung wird dies, wie in einem Ausführungsbeispiel der Erfindung in den Fig. 2 und 3 schematisch gezeigt ist, in einfacher Weise dadurch erreicht, daß in die Schalterkontakte 1, 2 senkrecht zur Richtung der das Abheben des KontaktesverursachendenStromlinienSchlitze3 angebracht werden, wodurch die Stromlinien gezwungen werden, den aus der Fig. 2 ersichtlichen Weg zu nehmen, bei dem eine auf Abstoßung wirkende gegenseitige Beeinflussung infolge des vergrößerten Abstandes unmöglich gemacht ist.as to make that the distance between the side by side streamlines is artificially enlarged. According to the invention this is, as in an embodiment of the invention in FIGS. 2 and 3 schematically is shown, achieved in a simple manner that in the switch contacts 1, 2 perpendicular to the direction of the streamline slots causing the contact to lift 3 are attached, whereby the streamlines are forced, which can be seen from FIG To take away in which a mutual influence acting on repulsion as a result of the increased distance is made impossible.
