Description
The ZW32-12 series outdoor AC high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12KV and a three-phase AC 50H2. It is mainly used to break and close the load current, overload current and short-circuit current in electronic systems. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, as well as in places where rural power grids are frequently operated. It can also be used as a sectional switch of the power grid. After adding a controller, the distribution network automation can be realized.

Application
Vacuum circuit breakers are widely used in power supply systems. In places such as power transmission and distribution, substations, industrial and mining enterprises, vacuum circuit breakers are often used to control and protect the normal operation of circuits. Vacuum circuit breakers have high short-circuit capabilities and sensitive protection functions that can quickly cut off fault current and protect the safe operation of power grid equipment and power facilities. At the same time, the vacuum circuit breaker can also be used as a segmented control device in the power system to realize segmented power supply to the power system and improve the reliability and flexibility of the system.
