Definitions

  • Rectangular capacitor units 1 do not fit well in cylindrical isolator housings, leaving much space to be filled with electrical isolator fluids, for example oil, SF 6 or Clean Air, resulting in big dimensions of the housings and high costs.
  • electrical isolator fluids for example oil, SF 6 or Clean Air
  • Another possibility is to form cylindrical capacitor units out of rectangular flat layer stacks, for example by cutting out cylindrical forms out of rectangular stacks. Cutting produces a lot of waste material, increases costs, introduces defects, and reduces lifetime of capacitor units 1.

Abstract

La présente invention concerne une unité condensateur (1) pour une application haute tension, comprenant au moins un empilement d'au moins une couche de matériau isolant (2), d'au moins une couche de matériau conducteur (3), d'au moins une autre couche de matériau isolant (2) et d'au moins une autre couche de matériau conducteur (3), empilées les unes à côté des autres. Ledit empilement est sous la forme d'un cylindre spiralé. Un procédé selon la présente invention comprend la formation d'au moins une couche de matériau isolant (2), d'au moins une couche de matériau conducteur (3), d'au moins une autre couche de matériau isolant (2) et d'au moins une autre couche de matériau conducteur (3) sur un empilement et l'enroulement de l'empilement sur un cylindre spiralé.
