Description

Isolator mit LichtleiterIsolator with light guide

Die Erfindung betrifft einen Hochspannungsisolator mit Lichtleiter der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a high-voltage insulator 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 Hochspannungspotential liegenden Meßwertauinehxer 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 Kunststoffumhüllung aufweist.From DE-PS 20 34 884 an insulating device for light signal transmission is from a measured value transducer at high voltage potential to an evaluation device, which has low voltage potential or earth potential, is known. It contains one made of fibrous stems with at least one suitable for light transmission Fiber optic bundle that extends from one end of the trunk to the other and has 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, 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.It is also known to convert light-guiding glass fiber bundles into protective Arrange porcelain insulators and drill the light guide into an outer one Coat in or out (DE-OS 29 01 872). The holes are made by subsequent Introducing molded plastic, the invention is based on the object of a indicate electrical insulator made of porcelain, in which a light guide is housed without adversely affecting the tracking resistance and surface quality will.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegeben Maßnahmen gelost.This object is achieved according to the invention by the in the characterizing part of claim 1 specified measures solved.

Durch die Erfindung ist es möglich, den Lichtleiter mit einem großen Biegeradius zu verlegen, so daß Knickstellen vermieden werden und die Lichtsignalübertragungsfähigkeit nicht beeinträchtigt wird.The invention makes it possible to use the light guide with a large To lay the bending radius, so that kinks are avoided and the light signal transmission capability is not affected.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt: Fig. 1 eine Schrägansicht eines Langstabilisators für Freileitungen und Fig. 2 einen Schnitt II-II zu Fig. 1.An exemplary embodiment of the invention is shown in the drawing. It shows: FIG. 1 an oblique view of a long stabilizer for overhead lines and FIG. 2 shows a section II-II to FIG. 1.

Der in Fig. 1 dargestellte Isolator 1 ist als Vollkernisolator ausgebildet und an seinen beiden Enden mit einer Netallkappe 2 versehen. Unter der Oberfläche des Hochspannungsisolators ist ein Lichtleiter 3 oder mehrere untergebracht.The insulator 1 shown in Fig. 1 is designed as a solid core insulator and provided with a metal cap 2 at both ends. Under the surface the high-voltage insulator accommodates a light guide 3 or more.

Der Isolator 1 wird aus einem Hubel abgedreht und bei etwa 1400°C ohne Glasur erstgebrannt. Nach den Erstbrand werden eine Rille 4 oder mehrere Rillen der Oberfläche des Porzellankörpers derart eingefräst, daß sie sich wendelförmig über Strunk und Schirme von einem Ende des Isolators bis zum anderen erstreckt. In der Rille 4 wird der bzw. die Lichtleiter 3 eingebracht.The insulator 1 is turned off from a hub and at about 1400 ° C First fired without glaze. After the first firing, one groove becomes 4 or more grooves the surface of the porcelain body milled in such a way that it is helical extends over the trunk and shields from one end of the insulator to the other. The light guide (s) 3 is introduced into the groove 4.

Anschließend wird der Porzellankörper mit einer Glasur 5 - beispielsweise durch Autspritzen - versehen. Dabei ist der Schmelzpunkt der Glasur 5 niedriger gewählt nie der Schmlezpunkt des Lichtleiters 3. Mit etwa 500° wird dann der mit der Glasur versehene Porzellankdrper nachgebrannt. Der Schmelzpunkt des Lichtleiters liegt bei etwa 600°C.Then the porcelain body with a glaze 5 - for example by spraying - provided. The melting point of the glaze 5 is lower never chosen the melting point of the light guide 3. With about 500 ° is then the porcelain body provided with the glaze is reburned. The melting point of the Light guide is around 600 ° C.

Es ist zweckmäßig, den Lichtleiter 3 in der Rille 4 von einer wärmedämienden Masse 6 zu umgeben.It is useful to have the light guide 3 in the groove 4 by a heat-insulating Surround mass 6.
