What is Embedded Pole VCB?
Embedded pole VCB used in medium-voltage switchgear system
An embedded pole VCB (vacuum circuit breaker) is a type of breaker where the vacuum interrupter is encapsulated within an epoxy resin insulation body.
This design ensures:
- Enhanced dielectric strength
- Improved environmental protection
- Reduced maintenance requirements
The embedded pole VCB is widely used in medium-voltage switchgear due to its durability and stable performance.
Structure of Embedded Pole VCB
A typical embedded pole VCB consists of:
1. Vacuum Interrupter
The core component responsible for arc extinction.
2. Epoxy Resin Encapsulation
Provides solid insulation and mechanical support.
3. Conductive Circuit Parts
Ensure reliable current flow.
4. Operating Mechanism
Controls opening and closing operations.
Working Principle
The embedded pole VCB operates using vacuum arc extinction technology.
When a fault occurs:
- Contacts inside the vacuum interrupter separate
- An arc is generated
- The vacuum environment quickly extinguishes the arc
- Current flow is safely interrupted
The encapsulated structure of the embedded pole VCB enhances insulation reliability and reduces environmental impact.
