Outdoor vacuum circuit breakers Assembly production line analysis

The assembly production line for outdoor vacuum circuit breakers is a highly automated system that includes key steps such as material verification, housing installation, operating mechanism assembly, vacuum interrupter positioning, and secondary circuit wiring. The line features energy-saving controls, safety protection measures, and the use of environmentally friendly materials. With PLC control and touch screen monitoring, the line ensures high consistency and efficiency in production while minimizing manual intervention, ensuring the reliability and durability of outdoor circuit breakers.

Outdoor vacuum circuit breakers are high-voltage switching devices designed for outdoor environments and are typically required to withstand harsh weather conditions and environmental impacts.

Here is an overview of the structure, assembly process, and assembly production line for outdoor vacuum circuit breakers:

Structural Features:

1. Housing: Usually made of robust and durable materials to protect internal components from outdoor environmental erosion.
2. Vacuum Interrupter Chamber: As the core part of the circuit breaker, it is responsible for extinguishing the arc when breaking the current.
3. Operating Mechanism: Likely spring-motor-driven, including metal parts, springs, motors, and gaskets.
4. Secondary Circuit: Responsible for the control and signal transmission of the circuit breaker.

Assembly Process:

1. Material Check: Ensure all parts and materials meet the requirements.
2. Housing and Auxiliary Unit Installation: Assemble the breaker’s housing and auxiliary units.
3. Make and Break Unit Assembly: Install and adjust the make and break unit of the circuit breaker.
4. Operating Mechanism Setup: Set up the operating mechanism according to design requirements.
5. Vacuum Interrupter Chamber Installation: Install the vacuum interrupter chamber in place and ensure it is sealed.
6. Secondary Circuit Wiring: Complete the wiring of the secondary circuit for the circuit breaker.

Assembly Production Line:

1. Automated Production Line: Includes areas such as the feeding area, mechanism assembly area, first waiting area, insulating cylinder assembly area, run-in area, repair area, testing area, chassis car assembly area, arm assembly area, and off-line area, forming a cyclic production line.
2. Production Rhythm: Based on the rated voltage of the circuit breaker, different daily and annual production capacities, as well as production rhythms, are set.
3. Testing Process: The production line integrates a run-in testing system, mechanical characteristic testing system, withstand voltage testing system, and final inspection testing system.
4. Energy-saving Requirements: The production line is designed with energy-saving features, such as automatic stoppage when there is no transport task.
5. Safety and Environmental Protection: The production line meets the relevant standards for mechanical safety, electrical safety, and environmental protection, such as the “Safety Evaluation Standards for Machinery Factories.”

The production line for outdoor vacuum circuit breakers is designed to consider various factors such as production efficiency, product quality, operational safety, and environmental protection to achieve efficient and reliable production operations.
