Vue d’ensemble<\/strong>
\nLe dispositif GCS convient aux syst\u00e8mes de distribution d’\u00e9lectricit\u00e9 dans des industries telles que les centrales \u00e9lectriques, le p\u00e9trole, les produits chimiques, la m\u00e9tallurgie, les textiles et les immeubles de grande hauteur. Dans les centrales \u00e9lectriques \u00e0 grande \u00e9chelle, les syst\u00e8mes p\u00e9trochimiques et d’autres environnements hautement automatis\u00e9s n\u00e9cessitant des capacit\u00e9s d’interface informatique, le dispositif GCS sert d’ensemble de commutateurs \u00e0 basse tension pour la distribution, le contr\u00f4le centralis\u00e9 du moteur et la compensation de puissance r\u00e9active dans les syst\u00e8mes de production d’\u00e9nergie et d’alimentation avec une fr\u00e9quence AC triphase de 50 (60) Hz, une tension nominale de fonctionnement de 380V (400V), (660V) et un courant nominal de 4000A ou inf\u00e9rieur.
\nLa conception de l’\u00e9quipement est conforme aux normes suivantes;
\nIEC 439-1 \u00c9quipements de commutation et de commande \u00e0 basse tension;
\nGB 7251 Ensembles de commutateurs \u00e0 basse tension;
\nZBK 360001 Ensembles de commutateurs r\u00e9tractables \u00e0 basse tension.<\/p>\n

Main Structure<\/strong><\/p>\n

\u25aa The main frame uses 8MF-type open-section steel, with instalation holes on both sides of the steel with module sizes of 20mm and 100mm and adiameter of \u04249.2mm, allowing for flexible and convenient internal installation;<\/p>\n

\u25aa The main frame assembly design offers two options: a fully assembled structure and a partialy welded structure (side frames and crossbeams) allowing users to choose according to their needs;<\/p>\n

\u25aa The functional compartments of the device are mutually isolated, divided into functional unit compartments, busbar compartments, and cablecompartments.Each compartment operates independently.<\/p>","protected":false},"excerpt":{"rendered":"
