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; 

Superior breaking performance: its spring operating mechanism adopts true moving gear transmission and multi-stage tripping system, with high reliability of action; good breaking performance, breaking short-circuit current of 20kA up to 30 times； 

Excellent external insulation performance: The unique silicon rubber sleeve inlet and outlet structure is used to make the insulation distance between the sleeves more abundant, and the operation is safe and reliable; 

Reliable sealing performance: Using mature sealing structure technology, the main circuit and secondary components are sealed in SF6 gas (zero gauge pressure), and the sealing performance is reliable;

Powerful communication function: There is an aviation socket under the operating mechanism, which is connected with the intelligent controller, which can realize the four remote functions of remote control, remote signaling, remote measurement and remote adjustment.
