vacuum recloser / power / automatic CHZ9

CHZ9-12 Outdoor Pole HV Vacuum Recloser (hereinafter referred to as circuit breaker) is a kind of outdoor intelligent vacuum switchgear, three-phase AC, with rated voltage of 12kV, rated frequency of 50Hz. The recloser is made up of CH series reclosing controller and ZW32-12/T630-20 type pole AC HV vacuum circuit breaker. It not only has all functions of ZW32-12type vacuum circuit breaker; but also has functions of reclosing and automatic closing and locking relying on the reclosing controller so that it can automatically eliminate instantaneous faults on lines and isolate permanent faults. In addition, it also can be flexibly used in substation in the end of the city network, ring network power supply lines and rural power network lines in combination with HV sectionalizer, to form a relatively advanced and economic power system with automatic control and protection functions. It is the first choice of the new generation outdoor HV switch equipment for renovation and reformation of the city net and rural net.
