10kV Pole-Mounted Vacuum Circuit Breaker

Understanding the Equipment
A circuit breaker that uses the high dielectric strength of vacuum to extinguish the arc.

Vacuum Circuit Breaker
Currently widely used in power distribution networks with voltage levels of 7.2–40.5kV.

Automatic Switching Function
Outdoor vacuum circuit breakers are mainly used in photovoltaic power systems to interrupt load current,
overload current, and short-circuit current.

They are suitable for use in substations and power distribution systems of industrial and mining enterprises for protection and control purposes.

Structure of the Circuit Breaker
The 10kV vacuum circuit breaker consists of an arc-extinguishing chamber, mechanism box, current transformer, voltage transformer, isolating switch, and other components.
