Indoor Circuit Breaker Production Line(VS1)
• Laser cutting/punching equipment: processes metal parts such as circuit breaker frames and operating mechanism housings.
• CNC machining centers: precision machining of core components like insulating pull rods, spindles, and drive parts.
• Bending and welding: automated bending machines form the enclosures, and robotic welding ensures structural strength.
• Epoxy resin casting/APG process: manufacturing vacuum arc suppression chamber support insulation tubes, insulating pull rods, etc.
• Surface treatment: applying anti-pollution flashover coatings (such as RTV silicone rubber).
• Operating mechanism assembly:
- Precise assembly of spring energy storage mechanism, opening and closing coils, and cam linkages.
- Mechanical characteristic testing (such as opening and closing times, bounce time).
• Modular assembly: Install the arc chamber, operating mechanism, and secondary control components •Electrical performance testing:
• Aging and reliability testing:
• Surface treatment: Electrostatic powder coating (anti-corrosion, wear-resistant).
• Intelligent packaging: Automatic film covering, boxing, and labeling (including QR code traceability).
Features
High-precision assembly
• Coaxiality error between vacuum interrupter and operating mechanism ≤ 0.1 mm.
• Spring storage capacity tolerance controlled within ±5%.
Intelligent control
• PLC+SCADA system for real-time monitoring of production data.
• Visual inspection (such as identifying defects on contact surfaces).
Flexible manufacturing
• Quick switching between different voltage level products such as VS1-12 (12kV) and VS1-24 (24kV).
Application
VS1 circuit breaker application scenarios
• Substations: Protection for incoming and outgoing lines in 10kV distribution systems.
• Industrial and mining enterprises: Protection for motors and transformers.
• New energy: Grid connection switches for photovoltaic/wind power step-up stations.
