Description

Vorrichtung zur Leitungsbefestigung an Stützisolatoren Bei der Verlegung von Hochspannüngsleitun,gen auf Masten wurden bisher Stützisolatoren. verwendet, welche zur Aufnahme der hohen B;iegungsbeanspruchungen mit einem inneren Metallbolzen verstehen sind. Das Einbringen dieses eisernen Bolzens in das Innere des Isolierkörpers setzt jedoch dessen Durchschlagsfestigkeit herab. Beim Übergang auf Stützisolatoren, bei denen .der Isolierstoff selbst (Porzellan, Steingut o. dgl.) zur Aufnahme der Biqgungsbea-nspruchung herangezogen wird, besteht jedoch gegebenenfalls die Gefahr, daß der Isolator umbricht.Device for fastening cables to post insulators When laying of high-voltage lines on masts have so far been post insulators. used, which to absorb the high bending loads with an inner metal bolt understand are. The introduction of this iron bolt into the interior of the insulator however, reduces its dielectric strength. When transitioning to post insulators, where .the insulating material itself (porcelain, earthenware, etc.) to accommodate the Contention is used, there is, however, a risk of that the insulator breaks.

ZTm in solchen Fällen den Isolierkörper vor mechanischen Beschädigungen zu schützen, wird erfindun,sgem.äß vorgeschlagen, die Leitung durch einen in der Verbindungsklemme befestigten Mitn!ehmer o. dgl. nachbpdebig in dem Isolatorkopf zu führen, so daß das Seil. beim Überschreiten der zulässigen Biegungsbeanspruchung des Isolators von diesem sich loslöst. Eine derartige nachgiebige Führung ist in der Zeichnung in zwei AusführungsbeIspiellen dargestellt. An der Verbindungsstellea ist ein keilförmIIgger Mitnehmer b (Abb. I) oder eine Rolle c (Abb. z) befestigt, welche auf einer ,schiefen -Ebene d des Isolatorkopfes gleitet und schließlich 'bei allzu starkem Anwachsen eines einseitigen Leitungszuges aus der keilförmigen Ausnehmung des Isolatorkopf es herausfällt.In such cases, ZTm protects the insulating body from mechanical damage to protect, it is proposed according to the invention, the line by one in the Connecting clamps fastened carriers or the like subsequently in the insulator head to lead so that the rope. when the permissible bending stress is exceeded the isolator detaches itself from it. Such a compliant guide is in shown in the drawing in two exemplary embodiments. At the junction a a wedge-shaped driver b (Fig. I) or a roller c (Fig. z) is attached, which slides on an inclined plane d of the insulator head and finally 'at excessive growth of a unilateral line from the wedge-shaped recess of the insulator head it falls out.
