Title
(EN) FILTER EQUIPMENT
(FR) EQUIPEMENT DE FILTRAGE
Abstract
(EN)
Filter equipment in an HVDC installation has a plurality of branches tuned to different frequencies. Each branch comprises a main capcitor (e.g. C11) and an inductor (L11), wherein the main capacitor comprises a plurality of series-connected capacitor units arranged in a substantially vertical stand. The main capacitors (C11, C13, C24, C36) for at least two branches are each arranged in a separate capacitor stack in one and the same stand. The stacks are electrically and mechanically interconnected at one end by means of connection members (MF), and otherwise separated and arranged at such a large distance from one another that the required insulation distance is obtained between the stacks.

Selon l'invention, un équipement de filtrage monté dans une installation à courant continu à haute tension comporte une pluralité de branches accordées sur différentes fréquences. Chaque branche comprend un condensateur principal (par exemple C11) et une bobine d'inductance (L11), le condensateur principal comprenant une pluralité d'unités de condensateur montés en série et disposés dans un support sensiblement vertical. Les condensateurs principaux (C11, C13, C24, C36) d'au moins deux branches sont disposés chacun sous la forme d'une pile, dans un seul et même support. Les piles sont reliées entre elles électriquement et mécaniquement, à une extrémité, au moyen d'éléments de connexion (MF), un espace suffisamment grand étant laissé entre lesdites piles pour que celles-ci soient séparées par la distance d'isolation requise.
