Abstract: Through the interpretation and analysis of the technical specifications for the standardized design of the 12 kV air-insulated ring main unit of the State Grid Corporation of China, and based on its main technical indicators, the design plan of the 12 kV air-insulated ring main unit products is given. The design plan focuses on two key technical parameters of lightning impulse withstand voltage and partial discharge value, and controls the insulation level of the ring main unit and the partial discharge value of the whole machine to formulate scientific production process specifications. Through prototype test verification, it is realized that the product meets the technical and mass production requirements in terms of electrical insulation performance and partial discharge indicators, and improves the reliability of equipment operation.
Key words: air-insulated ring main units; insulation level; partial discharge; type test
