Definitions

  • supporting structures appropriate to the type, in particular high-voltage overhead line pylons are usually made of metal in the basic construction.
  • plastics in the electrically relevant area of load-bearing components of the support structure, d. H . in demj enigen area that carries the at least one conductor or. is in contact with this .
  • the object is achieved according to the invention in that the grounding conductor is routed past the live conductor by means of a high-voltage bushing.
  • the high-voltage bushing suitably comprises an inner conductor which is passed through an insulating body.
  • the high-voltage bushing is expediently inserted in series in the grounding line, i.e. the inner conductor forms part of the grounding line or grounding conductor (or equivalently: the grounding line or grounding conductor forms the inner conductor in that section which is routed through the insulating body ) .
  • the holding device is formed at least partially from at least one insulating material.
  • load-bearing components of the device ie those who at least partially bear the weight of the current-carrying conductors and the weight of the holding device itself.
  • the holding device particularly preferably consists essentially entirely of one or more insulating materials.
  • FIG. 2 shows a section of a support structure according to the invention in a schematic representation.
  • the live conductors carry a voltage of more than 100 kV.
  • the grounding line with the grounding conductor 17 is at ground potential.
  • the use of the high-voltage bushing 19 allows isolating distances between the live conductors 4-7 and the ground conductor 17.
  • FIG. 2 shows a section of the support structure 21, which shows the construction of the high-voltage bushing 19.
  • the high-voltage bushing 19 includes an inner conductor 20 which is passed through an insulating body 22 .
  • the insulating body 22 comprises insulating layers 23, 24 made of paper, which are separated from one another by concentrically arranged, suffering control inserts 25, 26 for controlling the electric field.
  • the insulating body 22 is impregnated with a resin, preferably an epoxy resin.
  • the resin body of the insulating body 22 formed by the impregnation is directly embedded in the insulating foam 15, ie without its own housing.

Abstract

L'invention concerne une structure de support (1) pour un conducteur électrique présentant un dispositif de maintien destiné à maintenir au moins un conducteur chargé (4-7) et un conducteur de mise à la terre (17) destiné à mettre à la terre la structure de support. L'invention est caractérisée en ce que le conducteur de mise à la terre est guidé au-delà du conducteur chargé au moyen d'une traversée à haute tension (19).
