Abstract
Ein Isolator (1) aus Porzellan, insbesondere für Hochspannungsfreileitungen, ist über Strunk und Schirme mit einer wendelförmigen Rille versehen, in der mindestens ein Lichtleiter (3) untergebracht ist. Die Rille wird nachträglich mit einer erhärtenden Masse verfüllt.An insulator (1) made of porcelain, in particular for high-voltage overhead lines, is provided with a helical groove over the shank and shields, in which at least one light guide (3) is accommodated. The groove is subsequently filled with a hardening compound.

Die Erfindung betrifft einen Isolator mit Lichtleiter der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to an isolator with a light guide of the type mentioned in the preamble of claim 1.
Aus der DE-PS 20 34 884 ist eine Isoliereinrichtung zur Lichtsignalübertragung von einem auf Hochspannungspptential liegende Meßwertaufnehmer zu einer. Auswerteeinrichtung, die Niederspannungspotential oder Erdpotential besitzt, bekannt. Sie enthält einen aus Faserstoffen bestehenden Strunk mit mindestens einem zur Lichtübertragung geeigneten Glasfaserbündel, das sich von einem Ende des Strunks bis zum anderen erstreckt und eine den Strunk umgebende Kunststoffumhüliung aufweist.From DE-PS 20 34 884 an isolating device for the transmission of light signals from a to high voltage potential horizontal transducers to one. Evaluation device, the low voltage potential or earth potential, known. It contains a stalk consisting of fibrous materials with at least one fiber optic bundle suitable for light transmission, extending from one end of the trunk to the other and a plastic sheath surrounding the shank.
Ferner ist es bekannt, lichtleitende Glasfaserbündel in schützenden Porzellan-Isolatoren anzuordnen und den Lichtleiter durch Bohrungen in einen äußeren Mantel ein- oder auszuführen (DE-OS 29 01 872). Die Bohrungen werden durch nachträgliches Einbringen von Kunststoff vergossen.It is also known to arrange light-conducting glass fiber bundles in protective porcelain insulators and the Light guides through holes in an outer jacket or to run (DE-OS 29 01 872). The holes are cast by adding plastic later.
Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Isolator aus Porzellan anzugeben, in dem ein Lichtleiter untergebracht werden kann, ohne daß die Kriechstromfestigkeit und Oberflächenbeschaffenheit beeinträchtigt werden.The invention is based on the object of specifying an electrical insulator made of porcelain in which a light guide can be accommodated without affecting the tracking resistance and surface finish be affected.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Maßnahmen gelöst.This object is achieved according to the invention by what is stated in the characterizing part of claim 1 Measures resolved.
Durch die Erfindung ist es möglich, den Lichtleiter mit einem großen Biegeradius zu verlegen, so daß Knickstellen vermieden werden und die Lichtsignalübertragungsfäh'gkeit nicht beeinträchtigt wird.The invention makes it possible to lay the light guide with a large bending radius, so that kinks can be avoided and the light signal transmission capability is not affected.
