Abstract

L'invention concerne un condensateur de puissance haute tension, comprenant : une base (10) ainsi qu'un premier isolateur (20), un deuxième isolateur (30), un troisième isolateur (40), un quatrième isolateur (50), un cinquième isolateur (60), et un sixième isolateur (70) montés sur la base (10) afin d'augmenter le diamètre du haut vers le bas. La base (10) comprend trois isolateurs de montant (11) répartis selon un triangle équilatéral et un support (12) disposé sur les extrémités supérieures des isolateurs de montant (11). Le diamètre de chaque isolateur de montant (11) est de 356 mm ; les diamètres des six isolateurs de haut en bas sont : 610 mm, 610 mm, 665 mm, 705 mm, 715 mm et 715 mm. La structure du condensateur de puissance haute tension est simple et raisonnable. Trois isolateurs de montant (11) sont disposés sur la base (10), et le diamètre des six isolateurs disposés sur la base (10) est croissant de manière trapézoïdale de haut en bas, de sorte que le centre de gravité du condensateur est stable, ce qui permet de mieux résister aux dommages externes, tels que le vent et les tremblements de terre, d'économiser les coûts et d'augmenter la durée de vie du condensateur.
