Overview of Vacuum Circuit Breakers
Vacuum circuit breakers (VCB) are widely used in medium-voltage electrical systems for reliable switching and protection. They utilize vacuum interrupters to extinguish arcs, ensuring safe, efficient, and long-lasting performance.
VCBs are commonly applied in power distribution networks, substations, industrial plants, and renewable energy systems, offering superior reliability compared to traditional breakers.
How Vacuum Circuit Breakers Work
Vacuum circuit breakers interrupt current by separating contacts inside a vacuum chamber.
| Component | Function |
|---|---|
| Vacuum Interrupter | Extinguishes arc in vacuum |
| Moving & Fixed Contacts | Open/close electrical circuit |
| Operating Mechanism | Controls switching operation |
| Insulation Housing | Provides electrical insulation |
