ZW32-12F Outdoor high-voltage AC dividing vacuum circuit breaker

Medium voltage components   

ZW32-12F type outdoor high-voltage AC dividing circuit breaker is a new intelligent product developed in ZW32-12, consisting of three major parts: vacuum circuit breaker body, intelligent controller and external voltage transformer, the product is suitable for use in 10kV city network and agricultural network overhead ring network lines as sectional isolation switch and contact switch, which can realize automatic switching device for load deployment in ring network lines, and in large users The product is suitable for use as a sectional disconnector and contact switch in overhead ring network lines of 10kV urban and agricultural networks, and as an automatic switching device for load deployment of ring network lines, and as a demarcation switch (commonly known as "open-door dog") in branch lines of large users. The boundary breaker has protection and control functions and can reliably judge and detect the zero sequence current in the boundary to automatically remove single-phase earth faults and phase-to-phase short-circuit faults.
