Alimentation redondante ou alimentation sans interruption (ASI) ?"},"content":{"rendered":"

Dans le domaine de l'automatisation industrielle, des centres de donn\u00e9es et des infrastructures critiques, il n'est pas n\u00e9gociable de garantir une alimentation ininterrompue. Deux solutions courantesAlimentations redondantes<\/strong> et Alimentations sans interruption (ASI)<\/strong>-sont souvent mentionn\u00e9s ensemble, mais ils ont des objectifs distincts. Il est essentiel de comprendre leurs diff\u00e9rences pour concevoir un syst\u00e8me \u00e9lectrique r\u00e9silient.<\/p>\n\n\n\n

? Alimentation redondante : Fiabilit\u00e9 parall\u00e8le<\/strong><\/h2>\n\n\n\n

A Alimentation redondante<\/strong> Le syst\u00e8me d'alimentation de secours implique g\u00e9n\u00e9ralement deux ou plusieurs unit\u00e9s d'alimentation \u00e9lectrique connect\u00e9es en parall\u00e8le pour partager la charge. Si une unit\u00e9 tombe en panne, l'autre ou les autres prennent imm\u00e9diatement le relais sans interruption.<\/p>\n\n\n\n

Comment cela fonctionne-t-il ?<\/strong><\/h3>\n\n\n\n
    \n
  • Deux ou plusieurs blocs d'alimentation sont connect\u00e9s au\u00a0m\u00eame entr\u00e9e AC<\/strong>\u00a0et\u00a0m\u00eame bus de sortie DC<\/strong>.<\/li>\n\n\n\n
  • Ils fonctionnent en parall\u00e8le, souvent avec un circuit de partage du courant.<\/li>\n\n\n\n
  • En cas de d\u00e9faillance d'une unit\u00e9, la ou les unit\u00e9s restantes prennent en charge sans interruption les appareils connect\u00e9s.<\/li>\n\n\n\n
  • Parfois mis en \u0153uvre avec\u00a0modules d'isolation des diodes<\/strong>\u00a0afin d'\u00e9viter toute r\u00e9alimentation d'une unit\u00e9 d\u00e9faillante.<\/li>\n<\/ul>\n\n\n\n

    Objectif principal :<\/strong><\/h3>\n\n\n\n
      \n
    • Haute disponibilit\u00e9<\/strong>\u00a0et\u00a0temps de fonctionnement du syst\u00e8me<\/strong>\u00a0en \u00e9liminant un\u00a0point de d\u00e9faillance unique<\/strong>\u00a0dans l'alimentation elle-m\u00eame.<\/li>\n\n\n\n
    • Prot\u00e8ge contre\u00a0d\u00e9faillance mat\u00e9rielle de l'alimentation \u00e9lectrique<\/strong>, mais pas contre la perte de l'alimentation en courant alternatif.<\/li>\n<\/ul>\n\n\n\n

      Meilleure utilisation pour :<\/strong><\/h3>\n\n\n\n
        \n
      • Syst\u00e8mes de contr\u00f4le critiques (PLC, DCS, syst\u00e8mes de s\u00e9curit\u00e9).<\/li>\n\n\n\n
      • Serveurs, \u00e9quipements de r\u00e9seau avec deux entr\u00e9es d'alimentation.<\/li>\n\n\n\n
      • PC industriels et mat\u00e9riel d'automatisation pour lesquels les temps d'arr\u00eat sont co\u00fbteux.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        \u26a1 Alimentation sans interruption (ASI) : Combler les lacunes en mati\u00e8re d'alimentation<\/strong><\/h2>\n\n\n\n

        A UPS<\/strong> fournit une alimentation de secours temporaire \u00e0 partir de batteries (ou de volants d'inertie) lorsque l'alimentation principale en courant alternatif est d\u00e9faillante. Il garantit que l'\u00e9quipement connect\u00e9 continue \u00e0 fonctionner ou s'arr\u00eate de mani\u00e8re gracieuse pendant une panne de courant.<\/p>\n\n\n\n

        Types d'ASI :<\/strong><\/h3>\n\n\n\n
          \n
        1. ASI en veille (hors ligne)<\/strong>\u00a0- Bascule sur la batterie en cas de d\u00e9faillance du courant alternatif (temps de basculement court).<\/li>\n\n\n\n
        2. ASI interactif en ligne<\/strong>\u00a0- R\u00e9gule la tension et bascule sur la batterie en cas de besoin.<\/li>\n\n\n\n
        3. En ligne (double conversion) UPS<\/strong>\u00a0- Convertit continuellement le courant alternatif en courant continu, puis en courant alternatif, ce qui permet une isolation compl\u00e8te des perturbations de la ligne.<\/li>\n<\/ol>\n\n\n\n

          Objectif principal :<\/strong><\/h3>\n\n\n\n
            \n
          • Protection contre les pannes de courant alternatif<\/strong>, les coupures de courant, les baisses de tension et les surtensions.<\/li>\n\n\n\n
          • Fournit\u00a0temps de passage<\/strong>\u00a0pendant les courtes pannes ou jusqu'\u00e0 ce qu'un g\u00e9n\u00e9rateur d\u00e9marre.<\/li>\n\n\n\n
          • Permet de\u00a0fermeture ordonn\u00e9e<\/strong>\u00a0des syst\u00e8mes lors d'arr\u00eats prolong\u00e9s.<\/li>\n<\/ul>\n\n\n\n

            Meilleure utilisation pour :<\/strong><\/h3>\n\n\n\n
              \n
            • Ordinateurs, serveurs et infrastructure informatique.<\/li>\n\n\n\n
            • Instruments critiques dans les laboratoires, les soins de sant\u00e9 ou les t\u00e9l\u00e9communications.<\/li>\n\n\n\n
            • Toute application o\u00f9 une perte de puissance, m\u00eame br\u00e8ve, est inacceptable.<\/li>\n<\/ul>\n\n\n\n
