Description
VS1 high voltage VCB vacuum circuit breaker is suitable for three-phase AC 50Hz, 12kV power system. It can be used for protection and control of electrical equipment in industrial and mining, enterprises, power plants and substations.
Main feature
1. The vacuum circuit breaker adopts the design of the arc extinguishing chamber on the top and the operating mechanism on the bottom, which is easy to adjust.
2. The structure of combining air and organic composite insulating material is adopted.
3. Simple spring operating mechanism, the number of operations is 10,000 times.
4. Adopting the screw propulsion mechanism, the self-locking performance is stable and the self-locking is good.
