Within FN3-10 series 10KV Indoor Switches FN3-12R / 630A high voltage switches

I. Overview FN3-10? -type Indoor AC high voltage load open relationship phase AC 50Hz high voltage switchgear for rated voltage of 10KV power system, as under normal circumstances points, co-use circuits. Load switch with RN-pressure Fuse, breaking short-circuit current, as with short circuit and overload. Second, the structure Introduction Part load switch from the chassis, transmission, post insulator, knife and arc extinguishing devices into resistance. By a welded steel chassis and fitted with gearing. Knife by post insulators fixed on the bottom shelf, knife point of contact riveting limited contact, the ends of the movable contact mounted arc. Interrupter device and device and nozzle constitution. Plus comes with a jump cue at the end of the cam and fast closing spring for fast closing movements.
