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.

Safe and reliable; three-phase pillars and current transformers adopt imported outdoor epoxy resin solid insulation, or use indoor epoxy resin outsourcing silicone rubber solid insulation. It has the characteristics of high and low temperature resistance, ultraviolet resistance and aging resistance.

The performance is stable; the operating mechanism adopts a miniaturized spring operating mechanism, the power of the energy storage motor is small, and the energy consumption for opening and closing is low; the mechanism transmission adopts the direct transmission mode, the number of parts is small, and the reliability is high. The operating mechanism is placed in a sealed case, which solves the problem of corrosion of the operating mechanism and improves the reliability of the mechanism； 

The operation is convenient; the opening and closing operation of the circuit breaker can be operated manually or electrically and by remote remote control. It can be matched with intelligent controller to realize power distribution automation, and can also be combined with recloser to form automatic recloser and sectionalizer. 

It is easy to expand; the circuit breaker can be equipped with two-phase or three-phase current transformers for overcurrent protection and short-circuit protection, and can also provide current acquisition models for intelligent controllers; according to user requirements, metering current transformers can be installed.
