Abstract

La présente invention concerne une rangée de valves à thyristor commandées par une lumière et dotées d'un rayonnement de chaleur refroidi par eau. La rangée de valves présente une structure à deux tours. Une rangée de valves monophasées est composée de deux unités valve gauche et droite connectées en série. Un contacteur en feuille de cuivre souple est utilisé pour effectuer la connexion entre les unités valve gauche et droite. L'unité tuyau de chaque unité valve est disposée au centre de l'unité valve. L'unité thyristor (1) nécessitant d'être refroidie par eau et la résistance refroidie par eau (11) de l'unité de protection de résistance-capacité (3) sont disposées sur les deux côtés de l'unité tuyau. D'autres éléments exempts du refroidissement par eau de l'unité de protection résistance-capacité (3), à l'exception de la résistance refroidie par eau (11), de l'unité fente de câblage (6) et d'une bague en couronne (7) sont disposés autour de la rangée de valves. La résistance refroidie par eau (11) et un condensateur d'amortissement (12) sont appliqués suivant un agencement centralisé et disposés côte à côte sur un support de blocage. L'unité de protection résistance-capacité (3) est utilisée avec une conception de modularisation. Deux types d'unité de protection résistance-capacité bilatéralement symétriques peuvent être équipés de la même résistance refroidie par eau (11) et du même condensateur d'amortissement (12) disposés sur le support de blocage. L'invention présente de manière avantageuse une fiabilité élevée, une surface au sol restreinte, un trajet électrique et un trajet pour l'eau disposés séparément, et un refroidissement à l'eau pure.
