Description

Mit der Steigerung der Betriebsspannung von Hochspannungsfernleitungen auf 22o kV und 4oo kV steigen auch die Längen der Isolatorenketten. Um bei Lichtbogenüberschlägen die Beschädigung der Isolatoren zu vermeiden, macht sich insbesondere bei Langstab- und Vollkernisolatoren die Anbrin, gung von. Zwischen-Lichtbogen.-Schutzarmaturen zur Unterteilung der gesamten Kettenlänge erforderlich.With the increase in the operating voltage of high-voltage transmission lines The lengths of the isolator chains also increase to 22o kV and 4oo kV. To in case of arcing avoiding damage to the insulators is particularly useful for long rod and solid core insulators the attachment of. Intermediate arc protection fittings required to subdivide the entire chain length.

Die Befestigung derartiger Schutzarmaturen erfolgt bisher mittels Schellen oder Spannbacken an den Isolatorenkappen. Diese haben jethoch sehr unterschiedliche Maße und sind für derartige Zwecke nicht vorgesehen. Infolgedessen ist die Befestigung derartiger Schutzarmaturen schwierig.The attachment of protective fittings of this type has so far been carried out by means of Clamps or clamping jaws on the insulator caps. These are very different Dimensions and are not intended for such purposes. As a result, the attachment such protective fittings difficult.

Die Erfindung besteht darin, daß diese Schutzarmaturen nicht an dien Isolatorenkappen, sondern an an sich bekannten Doppelklöppeln befestigt werden. Diese Doppelklöppel besitzen eine laschenförmige Verstärkung, dtie entweder mit mehreren seitlichen Befestigungslöchern oder einem Mittelloch mit zusätzlichen beiderseitigen Querrippen versehen sind. Die Befestigung an einem derart passend geformten Doppelklöppel gestattet die Vereinheitlichung der Befestigungsart, die von der Form der Isolatorenkappe unabhängig ist.The invention consists in the fact that these protective fittings do not serve Isolator caps, but to be attached to double clappers known per se. These double clappers have a strap-shaped reinforcement, either with several mounting holes on the side or a central hole with additional holes on both sides Cross ribs are provided. The attachment to such a suitably shaped double clapper Allows for the unification of the fastening method, depending on the shape of the isolator cap is independent.

In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.Exemplary embodiments of the subject matter of the invention are shown in the drawing shown.

Abb. i zeigt eine .durch Zwischen-Lichtbogen-Schutzarmatur unterteilte Langstabisolatorenkette, Abb. 2 eine durch Zwischen-Lichtbogen.-Schutzarmatur unterteilte Vollkerriiisolatorenkette, Abb. 3 und 4 einen, mit mehreren Befestigungslöchern versehenen, durch Lasche verstärkten Doppelklöppel in Vorder- und Seitenansicht, Abt). 5 und 6 einen derartigen Klöppel mit Mittelloch und seitlichen Querrippen.Fig. I shows a long rod insulator chain divided by an intermediate arc protective fitting, Fig. 2 shows a full ceramic insulator chain divided by an intermediate arc protective fitting, Figs. 3 and 4 show a double clapper with several fastening holes and reinforced by a flap in front and side views , Abbot). 5 and 6 such a clapper with a central hole and lateral transverse ribs.

Der Doppelklöppel a ist an seinen beiden Enden mit Klöppeln b versehen, welche in die miteinander zu befestigenden Kappen c und d der Langstabisolatorenkette e bzw. f und g der Vollkern4solatorenkette h eingreifen.The double clapper a is provided at both ends with clapper bobbins which engage in the caps c and d of the long rod insulator chain e and f and g of the solid core insulator chain h, which are to be fastened to one another.

Der Doppelklöppel a besitzt eine laschenförmige Verstärkung i, die gemäß Abb. 3 mit zwei seitlichen Löchern k versehen'ist.The double clapper a has a strap-shaped reinforcement i, which according to Fig. 3 with two lateral holes k 'is provided.

Gemäß Abb. 5 und 6 besitzt der Klöppel lediglich ein Mittelloch 1, in welches eine zentrale Befes.tigungsschraube eingreift. Das. Verdrehen der Armatur wird durch beiderseitige Querrippen m verhindert, welche in entsprechende Aussparungen der Schutzarmatur eingreifen.According to Fig. 5 and 6, the clapper has only one central hole 1, in which a central fastening screw engages. That. Twisting the fitting is prevented by cross ribs m on both sides, which in corresponding recesses the protective fitting intervene.

Abb. i veranschaulicht die Verbindung von Schutzarmaturen n. bzw. Kammwulstringen, deren Streben o mit Doppelklöppel a befestigt sind. Gemäß Abb.2 ist die Zwischen-Lichtbogen-Schutzarmatur als, Schutzhorn p ausgebildet.Fig. I illustrates the connection of protective fittings n. Or Kammwulstringen, the struts o are attached with double clapper a. According to Fig.2 the intermediate arc protective fitting is designed as a protective horn p.

Es. liegt im Rahmen der Erfindung, die Isolatorenketten auch durch. andere geeignete Zwischen-Lichtbogen-Schutzarmaturen zu unterteilen, und erfindungsgemäß an dien mit Verstärkungslaschen i versehenen Doppelklöppeln zu befestigen.It. is within the scope of the invention, the isolator chains also by. to subdivide other suitable inter-arc protective fittings, and according to the invention to be attached to the double clappers provided with reinforcement straps i.
