CKWZ-12 outdoor AC high voltage vacuum circuit breaker is a new generation of outdoor vacuum circuit breaker self-developed on the basis of fully absorbing the advanced technology of column circuit breakers at home and abroad, combined with the application requirements of power equipment in my country. CKWZ-12 outdoor AC high voltage vacuum circuit breaker is an outdoor power distribution equipment with a rated voltage of 12kV and a 50Hz three-phase AC. It is mainly used for breaking and closing the load current, overload current and short-circuit current in the distribution network, and can realize the automatic protection of the distribution network step by step. It is a novel device in the distribution network. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises, and is more suitable for rural power grids and frequently operated places, especially for the construction and reconstruction of urban power grids and rural power grids. Features The design is exquisite; the circuit breaker adopts a three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no combustion and explosion danger, maintenance-free, small size, light weight and long service life. Strong applicability; the circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve the performance of moisture-proof and anti-condensation, and is especially suitable for use in cold or humid areas.
