L’article 706,<\/span><\/strong>\u00a0qui concerne les syst\u00e8mes de stockage d’\u00e9nergie (SSE), est particuli\u00e8rement int\u00e9ressant\u00a0\u00a0. Il couvre tous les syst\u00e8mes install\u00e9s de mani\u00e8re permanente, y compris les dispositifs \u00e9lectrochimiques (par exemple, les batteries), \u00e9lectrolytiques (par exemple, les batteries de condensateurs) et les dispositifs stockant l’\u00e9nergie cin\u00e9tique (par exemple, l’air comprim\u00e9). La\u00a0premi\u00e8re<\/strong><\/span>
\npartie\u00a0de l’article d\u00e9finit les exigences g\u00e9n\u00e9rales, telles que le champ d’application et diverses d\u00e9finitions. Il stipule notamment que tout \u00e9quipement destin\u00e9 \u00e0 ces syst\u00e8mes de stockage doit \u00eatre r\u00e9pertori\u00e9. Des d\u00e9tails sont fournis sur les dispositifs de commutation (interrupteurs, sectionneurs, etc.) \u00e0 utiliser, notamment les conducteurs du syst\u00e8me qui doivent pouvoir \u00eatre \u00e9quip\u00e9s d’un dispositif de commutation.

L’article\u00a0<\/span>712<\/span><\/strong>\u00a0, compos\u00e9 de 9 parties, traite des syst\u00e8mes de distribution de courant continu (CC), y compris la source d’alimentation CC, les convertisseurs CC-CC, les charges CC et les charges CA aliment\u00e9es par des onduleurs CC-CA.<\/span>
\nLa partie\u00a0<\/span>1<\/span><\/strong>\u00a0, comme toujours, contient les exigences g\u00e9n\u00e9rales et les d\u00e9finitions. Elle pr\u00e9cise \u00e9galement que tous les appareils et \u00e9quipements utilis\u00e9s doivent \u00eatre r\u00e9pertori\u00e9s et homologu\u00e9s pour une utilisation en CC.<\/span>
\nLa partie\u00a0<\/span>2<\/span><\/strong>\u00a0\u00a0contient les exigences relatives aux circuits, telles que \u00a0 le dimensionnement des conducteurs\u00a0<\/span>d’alimentation<\/span><\/a>\u00a0et de d\u00e9rivation, ainsi que les tensions nominales du syst\u00e8me.<\/span>
\nLa partie\u00a0<\/span>3\u00a0<\/span><\/strong>\u00a0traite des disjoncteurs et de leur positionnement correct sur les conducteurs du syst\u00e8me.<\/span>
