1.1 FN12-24RD seri HV chanjman puffer-type chaj ak aparèy konpoze li se AC 24kV, 50Hz andedan kay la segondè-vòltaj chanje. Chanjman nan chaj ak paramèt segondè teknik ak mouvman serye, tip debaz li yo se pa manyèl, men tou, yo ka ekipe ak mekanis fonksyon elektwomayetik prentan. Ki baze sou puffer arc-extinguishing prensip, li ka kraze repete, pa bezwen chanje entèwonp vakyòm. Anba kondisyon sikwi nòmal, chanjman ki gen gwo vòltaj ka fè, pote ak kraze chaj aktyèl, e li gen kapasite pou fè aktyèl sikwi, epi pote aktyèl sikwi nan yon sèten tan.

1.1 FN12-24RD series HV puffer-type load switch and its composite apparatus is AC 24kV, 50Hz indoor high-voltage switch. The load switch with high technical parameters and reliable movement, its basic operating type is by manual, but also can be equipped with electromagnet spring operating mechanism. Based on puffer arc-extinguishing principle, it can break repeatedly, no need to change vacuum interrupter. Under normal circuit condition, high-voltage load switch can make, bear and break load current, and has the ability to make short-circuit current, and bear short-circuit current in certain times.
