Vacuum circuit breaker CKWB-12

SF6overcurrentAC

CKWB-12/T630-20 outdoor AC high voltage vacuum circuit breaker is an outdoor power distribution equipment with vacuum bubble arc extinguishing SF6 gas insulation, rated voltage 12kV, three-phase AC 50Hz. The sealing performance of the inlet and outlet casings has also been improved, and the overall sealing performance is excellent. The SF6 gas filled inside does not leak and is not affected by the external environment; the spring operating mechanism has high reliability and stability; the contact resistance of the main circuit is small, and the temperature rise low. It is mainly used for breaking and closing the load and short-circuit current of 10kV power system. It is suitable for protection and control in substations, industrial and mining enterprises, and rural power grid distribution systems, and is more suitable for occasions where the power grid is frequently operated. Features CKWB-12 outdoor AC high-voltage vacuum circuit breaker adopts box-type sealing structure, which has good sealing performance and is a maintenance-free product. Perfect protection function: not only has overcurrent protection, but also has zero sequence protection, which can distinguish internal/external faults; Flexible installation/operation: This product is convenient and flexible if it is mounted on a column or mounted on a seat; electric energy storage, electric opening and closing. At the same time, it has manual energy storage, manual opening and closing, and can be operated at close range or long distance;
