Description

Die Erfindung betrifft etine weitere Ausgiestaltung der abbrandarmen Lichtbogenschu.tzausrüstungen für Hochspannungsisolatoren nach dem Patent 870715-Wie bei dien LichtbogenschutzausTüstungen nach dem Hauptpatent ist jedes, der freien Enden der z. B. an, der Seilklemme und gegebenenfalls auch am Aufhängepunkt des Isolators. oder der Isalatorenkette oder an einer Stütze oder einem Stützenisolato.r oder einer Durchführung anzubringenden Lichtbogenschutzhörner oder -hornkreuze mit einem an einer Stelle seines Umfanges durch eine kurze Luftstrecke unterbrochenen Ringansatz ve,rsehwn. Dieser Ansatz ist nun. erfindungsgemäß als besonderer metallischer Abbrandkörper ausgeführt, der jeweils auf dem freien Hornlende so, befestigti, z. B. aufgeschraubt wird, daß die Ringöse symmetrisch zur Gewinde- bzw. Hornachse liegt.The invention relates to a further embodiment of the low-burnup Arc protection equipment for high-voltage insulators according to patent 870715-Wie In the case of the arc protection equipment according to the main patent, everyone is free Ends of z. B. on, the rope clamp and possibly also at the suspension point of the Isolator. or the isolator chain or on a support or a support isolato.r or a bushing to be attached with arcing horns or horn crosses one interrupted by a short air gap at one point on its circumference Ring attachment ve, rsehwn. That approach is now. according to the invention as a special metallic one Abbrandkörper carried out, each on the free horn loin so, fastened, z. B. is screwed on that the eyelet is symmetrical to the thread or horn axis.

Diese Ausführung hat den, Vorteil, daß die Ösein jeder Lage, die der Abbrandkörper nach dem Aufschrauben einnehmen kann, die Schlagweite zwischen den, an den Enden, des Isolators angebrachten Lichtbogens-chutzausrüstu.ngen nicht verkürzt.This embodiment has the advantage that the Öbe each position that the Burn-up body can take after screwing, the throw distance between the, Arc protection equipment attached to the ends of the insulator is not shortened.

So zeigen z. B. Ab@b. i und 2 einen. deraritigen, aus Metall gegossenen, aufschraubbaren Abbrandkörper birnenförmiger Gestalt. Dieser ist senkrecht zu seiner Längsachse einges,ägti, so, daß ein Ringansatz entsteht, der mit dem birnenförmigen Grundkörper nur an einer Stelle verbunden ist. Dieser Ringansatz isst ferner am Umfang in, unmittelbarer Nähe der Verbindungsstelle mit dem Grundkörper aufgetrennt, so daß eine kurze Unterbrechung des Ringes entsteht. Die Ecken und Kanton des. Ringansatzes. sind an der Trennstelle gut abgerundet.So show z. B. Ab @ b. i and 2 one. such, cast from metal, screw-on burn-up body of pear-shaped shape. This is perpendicular to his Longitudinal axis inserted, ägti, so that a ring approach is created, which with the pear-shaped The main body is only connected at one point. This ring approach also eats on The circumference is separated in the immediate vicinity of the connection point with the base body, so that there is a short interruption in the ring. The corners and canton of the ring approach. are well rounded at the point of separation.

Abb. 3 und q. stellen ade weiteres. Ausführungsbeispiel einen Ringansatz nach der Erfindung dar, der ebenfalls symmetrisch zur Hornlachse auf dem Ende des, Schutzhornes. befestigt, z. B.. aufgeschraubt werden kann. Das freie Ende dieses Ringansatzes ist an der Unterbrechungsstelle aus der Ringebene tretend enn Stück nach rückwärts gebogen.Fig. 3 and q. say goodbye to more. Embodiment a ring approach according to the invention, which is also symmetrical to the horn salmon on the end of the, Protective horn. attached, e.g. B .. can be screwed on. The free end of this The ring attachment is stepping out of the ring plane at the point of interruption bent backwards.
