Summary
        Zw32-12m series outdoor column permanent magnet vacuum circuit breaker (hereinafter referred to as circuit breaker) is a new generation of circuit breaker with yCd series permanent magnet mechanism, which is rated voltage 12kV, three-phase AC 50Hz outdoor power distribution equipment is mainly used for breaking and closing load current, overload current and short-circuit current in the power system, which is suitable for urban and rural power supply The network is used for protection and control, and is more suitable for frequent operation places.
        Zw32-12m series outdoor column permanent magnet vacuum circuit breaker independently developed and developed conforms to China's national standards gb1984-2014, gb311.1-1997, gb11022- In 1999 and dl402-1991, AC high-voltage circuit breakers are required to order technical conditions, which have the characteristics of long electrical life, reliable disconnection and maintenance free. They are used in combination with intelligent permanent magnet controller as loop network line segments. They can automatically detect, isolate and alarm branch line faults, monitor the operation of lines, and have the function of automatically recovering non fault power supply The measurement, protection, control and communication function modules shall be configured to meet the requirements of power distribution automation.
         Zw32m-12 outdoor high voltage permanent magnet vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short circuit current in power system. It is suitable for protection and control of power distribution system in substations, industrial and mining enterprises, and rural power grid Frequent operation place.
The circuit breaker has the characteristics of small volume, light weight, anti condensation, maintenance free, etc., and can adapt to the harsh weather conditions and pollution environment.
        This type of product is operated by a permanent magnet operating mechanism. Because the permanent magnet operating mechanism is provided with a holding force to keep the switch in the opening and closing position, its mechanical parts The reliability and mechanical life of the switch are greatly improved due to the small quantity and short mechanical transmission chain.

Environmental conditions for use
a) Ambient temperature: - 40 ℃ ~ + 40 ℃;
b) The pollution level is not greater than level IV;
c) The altitude shall not exceed 2000m;
d) The wind pressure shall not exceed 700pa (equivalent to 34m / s of wind speed)
e) No place with fire, explosion and chemical corrosion;
f) There is no frequent violent vibration, and the seismic intensity is not more than 8 degrees.
