Description

Lichtbogenschutz für Langstabisolatoren Zum Schutz der Langstabisolatoren werden nach bereits bekannten Ausführungen über der Leitungsklemme angeordnete, metallische Lichtbogenschutzringe verwendet, deren z. B. vierarmige Verstrebungen sich über den Schutzring in hörnerartig nach außen gebogenen Ansätzen fortsetzen. Es hat sich gezeigt, daß der Überschlaglichtbogen mit Vorliebe auf die zwischen diesen Hornansätzen liegenden Bogenstücke des Schutzringes überspringt, so daß die Isolatoren in das Bereich des Lichtbogens gelangen und u. U. seinen zerstörenden Wirkungen ausgesetzt werden.Arc protection for long rod insulators To protect long rod insulators are arranged according to known designs above the cable clamp, metallic arc protection rings used whose z. B. four-armed struts continue over the protective ring in horn-like outwardly curved approaches. It has been shown that the flashover arc with preference on the between these horn approaches lying arc pieces of the protective ring skips so that the Insulators get into the area of the arc and possibly its destructive Effects are exposed.

Diesem Übelstand kann erfindungsgemäß durch die beispielsweise in den Abb. i und 2 dargestellte, verbesserte Ausführungsform der Lichtbogenschutzringe abgeholfen werden, bei der die Verstrebungen des Schutzringes nicht hörnerartig über diesen hinausgeführt sind, sondern die in der Mitte der Bogenstücke zwischen den Befestigungsstellen der Verstrebungen an dem Schutzring nach außen gebogene Hörner aufweist. Hierbei wird der Lichtbogen durch die elektrodynamischen Wirkungen nach der Ansatzstelle des Hornes, die in der Mitte des Bogenstückes liegt, hingedrängt und gleitet dann auf dem Horn nach außen ab, so daß er erlischt.According to the invention, this drawback can be overcome by, for example, in Figs. i and 2 shown, improved embodiment of the arc protection rings be remedied in which the struts of the protective ring are not horn-like are led beyond this, but those in the middle of the arc pieces between the fastening points of the struts on the protective ring bent outwards Has horns. Here, the electric arc is created by the electrodynamic effects after the point of attachment of the horn, which is in the middle of the bow, pushed and then slides outward on the horn so that it goes out.

Abb. i zeigt in Seitenansicht und Abb. 2 in Aufsicht einen solchen über der Leitungsklemme anzubringenden, neuartigen Lichtbogenschutz. Die Verstrebungen To und I i enden ohne Verlängerung am Schutzring 12 und sind an den Stellen 13, 14, 15 und 16 mit diesem verbunden, z. B. verschweißt. In der Mitte der Bogenstücke des Schutzringes 12 zwischen den Verbindungsstellen 13, 14, 15 und 16 sind nach außen gebogene Hörner 17, 18, 19 und 2o angebracht.Fig. I shows such a side view and Fig. 2 in plan view New type of arc protection to be attached over the cable clamp. The bracing To and I i end without extension at the protective ring 12 and are at the points 13, 14, 15 and 16 connected to this, e.g. B. welded. In the middle of the bow pieces of the protective ring 12 between the connection points 13, 14, 15 and 16 are after outside curved horns 17, 18, 19 and 2o attached.
