Description

Die Erfindung ist eine weitere, sehr vorteilhafte Ausgestaltung der abbrandarmen Lichtbogenschutzausrüstungen für Hochspannungseinzelisolatoren und -isolatorenketten nach dem Patent 870 7i5.The invention is a further, very advantageous embodiment of the low-burn arc protection equipment for high-voltage individual insulators and -isolator chains according to patent 870 7i5.

Wie bei den L.ichtbogenschutzausrüstungen nach dem Patent 870 7,5 ist jedes der freien Enden der z. B. an der Seilklemme und gegebenenfalls auch amAufhängepunktdes Isolators oder der Isolatorenkette oder an einem Stütz- oder Stützenisolator oder einer Durchführung anzubringenden Lichtbogenschutzhörner oder Hornkreuze ring- oder ösenförmig umgebogen, und es ist jede dieser Ösen in ihrer Ebene durch eine kurze Luftstrecke an einer Stelle unterbrochen. Erfindungsgemäß wird nun das freie Ende der in dieser Weise ring- oder ösenförmig ausgebildeten Hornäste an der Unterbrechungsstelle ein Stück nach rückwärts verlängert.As with the arc protection equipment according to the patent 870 7.5 , each of the free ends of the z. B. on the cable clamp and possibly also on the suspension point of the insulator or the insulator chain or on a support or pillar insulator or a bushing to be attached arc protection horns or horn crosses in a ring or loop, and each of these loops is interrupted in its plane by a short air gap at one point . According to the invention, the free end of the horny branches formed in this way in the shape of a ring or loop is now lengthened a little backwards at the point of interruption.

Abb. i stellt z. B. in Seitenansicht und Abb. z in Aufsicht eine Lichtbogenschutzausrüstung für Ketten- und Einzel-, z. B. Langstabisolatoren dar, bei der die mit ring- oder ösenförmigen Enden versehenen, nach außen abgewinkelten Hornäste zwischen halbkreisförmigen Bogenstücken hindurchgreifen. Erfindungsgemäß ist, wie die Abb. i und 2 zeigen, das freie Ende jedes Hornastes an der Unterbrechungsstelle ein; Stück nach rückwärts verlängert, und zwar kann wie in vergrößertem Maßstab aus Abb.3 ersichtlich ist, dieses Ende nach rückwärts aus der Ebene der Öse herausgeführt sein. Abb. q. zeigt eine weitere -beispielsweise Ausführungsform der Erfindung, bei der das freie Ende des ring- oder ösenförmigen Ansatzes vor der Unterbrechungsstelle ein Stück nach rückwärts parallel zum Hornäst verlängert ist. Durch die Anordnung nach der Erfindung wird mit Sicherheit vermieden, daß sich an der Unterbrechungsstelle des ring- oder ösenförmigen Ansatzes auch nur geringfügige Schmelzperlen u. dgl. bilden.Fig. I shows e.g. B. in side view and Fig. Z in plan view of an arc protection equipment for chain and single, z. B. long rod insulators, in which the outwardly angled horn branches, provided with ring-shaped or loop-shaped ends, reach through between semicircular curved pieces. According to the invention, as FIGS. I and 2 show, the free end of each horn branch is at the point of interruption; Piece lengthened backwards, as can be seen on an enlarged scale from Fig. 3, this end can be led backwards out of the plane of the eyelet. Fig.q. shows a further - for example embodiment of the invention, in which the free end of the ring-shaped or loop-shaped extension in front of the interruption point is extended a little backwards parallel to the horny branch. By the arrangement according to the invention it is avoided with certainty that even only slight melting pearls and the like are formed at the point of interruption of the ring-shaped or loop-shaped attachment.
