Definitions

  • the invention relates to a surge arrester with at least one varistor element which is clamped between two end fittings, the end fittings having at least one recess and being connected to one another by means of at least one pulling element which passes through the recesses and carries holding elements which are each supported on the edge of a recess are.
  • Such a surge arrester is known, for example, from Japanese Patent Application Laid-Open No. 63-312602.
  • varistor elements are clamped between two end fittings, which are clamped together by means of several threaded rods distributed around the circumference.
  • the threaded rods have threads at their ends, onto which nuts are screwed, which serve as holding elements.
  • the present invention has for its object to provide a surge arrester of the type mentioned in such a way that assembly is facilitated and the structure is simplified.
  • the object is achieved in that the holding elements are crimp sleeves.
  • the crimp sleeves can be crimped onto the tension elements by means of a conventional crimping tool, a distance between the crimp sleeves on the respective tension element being maintained which is adapted to the intended distance between the end fittings.
  • a conventional crimping tool To assemble the surge arrester, the varistor elements and the end fittings as well as additional elastically compressible elements, which are arranged between the end fittings, are assembled and axially compressed and the tension elements are then attached to the crimped holding elements inserted into the recesses of the end fittings such that the holding elements are arranged on the sides of the end fittings facing away from the varistor elements and are supported on the edges of the recesses.
  • tension elements are tensioned only after assembly by pressure screws, which are provided in an end fitting and are supported on a stack element.
  • the crimp sleeves can also be glued onto them.
  • the tension elements can be designed, for example, as a glass fiber reinforced plastic rod.
  • the surge arrester can be cast with an elastomer, so that on the one hand the varistor elements and the tension elements are hermetically sealed and stabilized and on the other hand screens can be arranged on the lateral surface of the rotationally symmetrical surge arrester.
  • a particularly stable attachment of the crimp sleeves is possible if the crimp sleeves are made of metal.
  • An advantageous embodiment of the invention provides that the recesses are open towards the edge of the respective end fitting.

Abstract

L'invention concerne un coupe-circuit de surtension comprenant au moins un élément varistance (1, 2) qui est fixé entre deux supports terminaux (4,5). Les supports terminaux (4, 5) présentent au moins un évidement (12, 13) et sont reliés par au moins un élément de traction (6). Cet élément de traction (6) traverse les évidements (12, 13) et porte des éléments de maintien (8, 9) qui sont respectivement appuyés sur le bord (11) d'un évidement (12, 13). Les éléments de maintien sont des douilles serties.
