Abstract

Connection cable-eyes consist entirely of a non-metal material like plastic or a ceramic material. Stress corrosion cracking is avoided by not using metals or alloys like brass that are specifically at risk from stress cracking. Mechanically stable non-metal material is used.

Description

Die Erfindung betrifft einen Schlingenisolator mit einem schlingenförmigen Isolatorbauteil, das mit einander gegenüberliegenden Anschlusskauschen verbunden ist.The The invention relates to a loop insulator having a loop-shaped insulator component, that with each other Connection thimbles is connected.

Ein solcher Schlingenisolator ist beispielsweise aus der Veröffentlichung der Siemens AG mit der Bestellnummer A52813-W3001-A0001-02-00 B1 bekannt. Die dort beschriebenen Schlingenisolatoren SICAT 8WL3001/3002 werden eingesetzt, um die spannungsführende Oberleitung von elektrischen Bahnen vom Erdpotential zu isolieren. Das schlingenförmige Isolatorbauteil besteht aus glasfaserverstärktem Kunststoff, und zwar aus einem in sich geschlossenen glasfaserverstärkten Kunststoffstrang. An gegenüberliegenden Enden dieses schlingenförmigen Isolatorbauteils ist jeweils eine Anschlussarmatur angeordnet, die Anschlusskausche genannt wird. Diese Anschlusskauschen sind häufig aus einer Kupfer-Aluminium-Legierung gefertigt. Bei der Herstellung werden die mit Epoxidharz getränkten Glasfasern des Isolatorbauteils direkt auf die Anschlusskauschen gewickelt und dort gehärtet.On such loop insulator is for example from the publication Siemens AG with the order number A52813-W3001-A0001-02-00 B1. These Loop insulators SICAT 8WL3001 / 3002 are used. around the live Insulate overhead line of electrical tracks from earth potential. The loop-shaped Isolator component is made of glass fiber reinforced plastic, and indeed from a self-contained glass fiber reinforced plastic strand. On opposite Ends of this loop-shaped Isolator component is arranged in each case a connection fitting, the Connection exchange is called. These connection thimbles are often out made of a copper-aluminum alloy. In the preparation of are impregnated with epoxy resin Glass fibers of the insulator component directly onto the connection thimbles wound and hardened there.

Die bekannten Anschlusskauschen haben stets kreisrunde Öffnungen, in denen Anschlussbauteile wie Seile, Drähte oder Bolzen gehalten werden. In den Öffnungen befinden sich Kauscheneinsätze aus Kupfer-Aluminium-Legierung, aus Kupfer, Messing oder aus Polyamid. Das schlingenförmige Isolatorbauteil umgreift die Anschlusskauschen.The known connection thimbles always have circular openings, in which connection components such as ropes, wires or bolts are held. In the openings there are thimble inserts Copper-aluminum alloy, made of copper, brass or polyamide. The loop-shaped Isolator component surrounds the connection thimbles.

Die bekannten Anschlusskauschen der Schlingenisolatoren und die Anschlussbauteile bestehen aus unterschiedlichen Metallen, die unterschiedliche elektrochemische Spannungen haben. Es kann dadurch in Folge der Luftfeuchte zur elektrochemischen Korrosion kommen. Außerdem ist bei Anschlusskauschen aus Messing eine Spannungsrisskorrosion nicht auszuschließen.The Known connection thimbles of the loop insulators and the connection components consist of different metals, the different electrochemical Have tensions. It can thereby due to the humidity for electrochemical corrosion come. In addition is not a stress corrosion cracking at connection thimbles made of brass excluded.

Der Erfindung liegt die Aufgabe zugrunde, einen Schlingenisolator anzugeben, der nicht oder nur sehr wenig korrodiert und somit länger als ein bisher üblicher Schlingenisolator einsatzbereit ist.Of the Invention has for its object to provide a loop insulator, which does not or only very little corroded and thus longer than a previously common Loop insulator is ready for use.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, dass die Anschlusskauschen aus einem Metall, das elektrochemisch nicht reagiert und nicht zur Spannungsrisskorrosion neigt, oder aus einer Kombination von einem solchen Metall mit einem nichtmetallischen Stoff bestehen.The Task is according to the invention solved by that the connection thimbles are made of a metal that is electrochemical does not react and does not tend to stress corrosion cracking, or from a combination of such a metal with a non-metallic one Fabric exist.

Dadurch, dass vermieden wird, zwei elektrochemisch reagierende Metalle aneinandergrenzen zu lassen, wird die elektrochemische Korrosion vermieden. Dadurch dass gezielt spannungsrissgefährdete Metalle oder Legierungen wie Messing nicht verwendet werden, wird eine Spannungsrisskorrosion vermieden.Thereby, it is avoided that two electrochemically reacting metals adjoin one another let the electrochemical corrosion is avoided. As a result of that deliberately susceptible to stress cracking Metals or alloys such as brass will not be used avoided stress corrosion cracking.

Beispielsweise ist der nichtmetallische Stoff Kunststoff oder eine Keramik. Damit wird der besondere Vorteil erzielt, dass ein mechanisch stabiler nichtmetallischer Stoff verwendet wird.For example is the non-metallic material plastic or a ceramic. In order to the particular advantage is achieved that a mechanically stable non-metallic Fabric is used.

Ein besonders geeignetes Metall ist Edelstahl, zum Beispiel Feinguss-Edelstahl. Edelstahl bildet vorteilhafterweise einen z.B. oxidischen Überzug aus, der eine elektrochemische Reaktion mit einem Metall des Anschlussbauteils nicht zulässt. Auch andere Metalle mit entsprechender Eigenschaft einen Überzug auszubilden sind geeignet, in der Regel aber zu teuer.On Particularly suitable metal is stainless steel, for example precision cast stainless steel. Stainless steel advantageously forms e.g. oxidic coating, the an electrochemical reaction with a metal of the connection component does not allow. Also other metals with the appropriate property to form a coating are suitable, but usually too expensive.

Wenn das Metall des Anschlussbauteils bekannt ist, kann auch das gleiche Metall für die Anschlusskausche gewählt werden.If The metal of the connection component is known, can also be the same Metal for the connection box selected become.

Es wird der besondere Vorteil erzielt, dass der Schlingenisolator trotz der Witterungseinflüsse nicht oder nur wenig kor rodiert und daher eine längere Einsatzzeit als bei bisherigen Schlingenisolatoren möglich ist.It the special advantage is achieved that the loop insulator despite the weather influences not or only slightly corroded and therefore a longer service life than in previous ones Loop insulators possible is.
