The invention concerns a system supplying uninterruptedly sensitive equipment having a supply interface of 230V/50 Hz, characterised in that it comprises, downstream of a high voltage/low voltage transformation station, a direct connection towards at least one Uninterrupted Power Supply (UPS), enabling to eliminate the Normal/Standby switch between the local electric network and the replacement source. The UPS, which comprises batteries in parallel and a quick switching device (t < 20 ms), automatically ensures the launching (or triggering) of the standby source in case of breakdown of the local electric power supply network. Reciprocally the standby source, which is directly coupled with the UPS batteries, delivers the direct current required for maintaining the charge of said batteries.
Ce système alimente sans interruption des équipements sensibles présentant une interface d'alimentation de 230V/50Hz. Il est caractérisé en ce qu'il comprend, en aval d'un poste de transformation haute tension/basse tension, une liaison directe vers au moins une unité d'Alimentation Sans Interruption (ASI), ce qui permet de supprimer la commutation Normal/Secours entre le réseau électrique local et la source de remplacement. L'ASI, qui comprend des batteries en parallèle et un dispositif de commutation rapide (t<20ms), assure automatiquement le lancement (ou le démarrage) de la source de remplacement en cas de défaillance du réseau local d'électricité. Réciproquement la source de remplacement, qui est couplée directement avec les batteries de l'ASI, délivre le courant continu nécessaire au maintien de la charge de ces batteries.
