The switchgear and ring main unit (RMU) production lines are dedicated to manufacturing and assembling high-voltage and medium-voltage switchgear used in power systems. These lines integrate advanced automation technology and precise processes to ensure the production of high-quality and reliable switchgear and RMUs.
The production line typically includes several key stages:
- Sheet Metal Processing Area: Here, machines like shearing machines, laser cutters, and bending machines are used to process sheet metal into various metal components for switchgear and RMUs.
- Structural Assembly Area: In this area, the sheet metal components are assembled into complete cabinet structures. This usually involves processes such as welding, bolting, and riveting.
- Electrical Component Installation Area: The assembled cabinets are transferred to this area where various electrical components, such as circuit breakers, contactors, relays, meters, and control devices, are installed.
- Harness and Cable Processing Area: This area is responsible for processing and installing cables and wiring, ensuring all electrical connections are correct and secure.
- Testing and Inspection Area: At the final stage of the production process, each switchgear and RMU undergoes a series of functional and electrical tests to ensure they meet all performance and safety standards.
- Quality Control: There are strict quality control measures throughout the production line, including inspection of raw materials, random checks during the production process, and comprehensive inspection of the final product.
- Automation Systems: Modern switchgear and RMU production lines often employ automated equipment and information management systems, such as PLC control systems and MES (Manufacturing Execution Systems), to improve production efficiency and reduce human errors.
