Ring main unit production line and mechanical property testing

The ring main unit production line and mechanical property testing are crucial components in the manufacturing of electrical equipment, ensuring the quality and performance of the ring main units. Here is a detailed introduction to the ring main unit production line and mechanical property testing:

1. Ring Main Unit Assembly Line: The ring main unit assembly line includes a main body, shuttle carts, workstations, etc., which use shuttle carts to move products through various workstations for preliminary welding, component assembly, and other steps. The production line utilizes automated equipment and information management systems to achieve full-process automation, with high adaptability and flexibility.
2. Mechanical Property Testing: Mechanical property testing is a key step in ensuring the performance of the switching components within the ring main unit. The testing includes parameters such as the operating speed, simultaneity, opening distance, over-travel, contact bounce, and re-bounce of the circuit breaker. By using mechanical property testers, loop resistance testers, and potential transformer polarity testers, the performance of the switching components can be comprehensively evaluated.
3. Ring Main Unit Comprehensive Performance Testing System: The comprehensive performance testing system includes wear-in tests, mechanical property tests, semi-finished product inspections, and finished product power tests. It communicates with the control management system via an Ethernet switch, enabling real-time data uploading and monitoring.
4. Gas Chamber Helium Inspection System: The helium inspection system is used for dry leak detection of SF6 gas chambers, conducting helium mass spectrometry leak testing to determine the qualification of the gas chamber and allowing for the recycling of helium gas.
5. Power Frequency Withstand Voltage Testing System: The power frequency withstand voltage testing system is used to verify the insulating strength of the ring main unit, including partial discharge tests and a shielding room for the test, ensuring the insulating performance of the ring main unit.
6. Control Management System: The ring main unit assembly line control management system uses barcode guns, RFID, and other technologies to manage and trace products and materials, as well as to monitor the status of each workstation on the production line and track the status of the products.
7. Environmental-friendly Design: Environmental-friendly ring main units use dry air or other environmentally friendly gases as insulating media, reducing greenhouse gas emissions, and include electrical five-prevention functions in the design to ensure operational safety.
8. Customization and Flexible Production: The assembly line can be customized and adjusted according to different product requirements, with the ability for flexible production to quickly respond to market changes.

Through the above processes, the ring main unit production line and mechanical property testing work together to ensure the high quality and performance of the ring main units, meeting the requirements of modern power systems for equipment.
