ZN65A Series Indoor High Voltage Vacuum Circuit Breaker;
General:
ZN65A--12 series indoor HV vacuum circuit breaker is the indoor HV switch with three-phase AC 50Hz, rated 7.2 - 12kV voltage. This circuit breaker meets the GB1984<AC HV Breaker>,JB3855<3.6--40.5KV indoor vacuum circuit breaker>,DI403<310--35KV indoor HV vacuum circuit breaker order technical specifications> and IEC standards, and possesses reliable interlock ability. The breaker can carry on operation frequently with the ability of opening or breaking many times and quick coinciding with the floodgate. It is designed for front and back branch load structure, and can regard the cell installed fixed admittedly and be used with hand car.
Overall structure:
ZN65A Series indoor HV Vacuum circuit Breaker architectural struture uses operation organization and front and back load extinguish arc room.the leading electricity loop feature is three phase console model constructs.The arc room vertial installs in pipe type insulation muff,the insulation muff is poured by APG's technology,thus it especially resisted creeping dischange.This kind of design has reduced the dust greatly together on the surface of arc room.and not only can prevent the vacuum arc room from influence of outside ,but also can ensure to appear high prevent type even in the environment of and hot and serious filth environment.
