Use instead of the circuit breaker switch due to load and easy to use affordable and therefore the load switch is widely used in 10kV distribution network system in a reasonable load switch is mainly used for breaking and closing load current and high-voltage fuse load switch also can cooperate in the design Selection load switch for safety and reliable operation of the grid is of great significance. Within FN12-12R.D / 100-31.5 type indoor AC high voltage load switch - fuse combinations (hereinafter referred to as FN12-12R.D combination of electrical appliances) are FN12-12D load switch off and S port LAJ-12 (XRNT mouth - 12) high-pressure limiting fuse together the indoor high voltage switchgear. It can be a reliable short-circuit current breaking up any current: breaking work load switch current Hengshui load switch, fuse breaking short-circuit current, breaking any overcurrent joint work between the current and total short-circuit current, while the fuse through its impact load switch allows opening. Baoding load switch _ _ Huayi load switch power provided by Xian Huayi power plant.
