Abstract
Description
Die
Erfindung betrifft einen Überspannungsableiter,
insbesondere einen Metalloxid-Überspannungsableiter
ohne Funkenstrecke und mit einem Kunststoffgehäuse, wie er in

Ein derartiger Überspannungsableiter wird als eine Überspannungsableiter mit Rohr-Design bezeichnet.One such surge arrester is called a surge arrester denoted by tube design.
Im Überlastungsfall
entwickelt sich innerhalb des Rohrs
Überspannungsableiter mit Rohr-Design werden in beachtlichen Längen hergestellt. Ein Überspannungsableiter dieser Bauart mit einer Bemessungsspannung von 200 kV erreicht eine Länge von ca. 2 m. Da diese Überspannungsableiter im Freien eingesetzt werden, sind sie auch großen mechanischen Belastungen durch Wind und/oder die angeschlossenen Leitungen ausgesetzt. Insbesondere wird eine sehr hohe mechanische Biegefestigkeit gefordert.Surge arresters with tube design are manufactured in considerable lengths. A surge arrester this type with a rated voltage of 200 kV reaches one Length of approx. 2 m. Because these surge arresters Used outdoors, they are also great mechanical loads exposed by wind and / or the connected lines. In particular, will a very high mechanical bending strength required.
Aufgabe der Erfindung ist es, die mechanische Festigkeit eines Überspannungsableiters mit Rohr-Design zu verbessern. Die Aufgabe wird durch einen Überspannungsableiter nach Anspruch 1 gelöst. Die abhängigen Ansprüche betreffen weitere vorteilhafte Aspekte der Erfindung.task The invention is the mechanical strength of a surge arrester to improve with tube design. The task is done by a surge arrester solved according to claim 1. The dependent ones claims relate to further advantageous aspects of the invention.
Im weiteren wird ein erfindungsgemäßer Überspannungsableiter unter Bezugnahme auf die Figuren ausführlich beschrieben, in denen zeigen:in the Another is an inventive surge arrester described in detail with reference to the figures, in which demonstrate:

Mit dieser Bauweise lässt sich die Biegefestigkeit des Überspannungsableiters deutlich erhöhen, und auch längere Bauweisen, über 2 m hinaus, sind möglich.With this construction leaves the flexural strength of the surge arrester increase significantly and longer Construction methods, about 2 m out, are possible.

Zur weiteren Verbesserung der mechanischen Eigenschaften des Überspannungsableiters können auch noch um den Stapel der Varistorblöcke 1 herum einzelne Stäbe vorgesehen sein, die sich über die gesamte Länge des Überspannungsableiters erstrecken und an beiden Endarmaturen in bekannter Art verankert sind. Diese Stäbe werden vorzugsweise aus einem glasfaserverstärkten Kunststoffmaterial gebildet.to Further improvement of the mechanical properties of the surge arrester can also still provided around the stack of Varistorblöcke 1 around individual rods be over the entire length the surge arrester extend and anchored to two end fittings in a known manner are. These bars are preferably formed from a glass fiber reinforced plastic material.
