The UHV AC gas-insulated GIS electromagnetic voltage transformer developed by Nisshin (Wuxi) electromechanical company passed all type tests in Wuhan. Two weeks earlier, the 1000kV capacitive voltage transformer developed by the State Grid Research Institute of Electrical Power passed a type test. Both products have been developed for the first time in the world and represent the highest level of international high voltage voltage transformer technology.
1000kV Jindongnan-Nanyang-Jingmen UHV AC pilot demonstration project uses open-type voltage transformers. To further compress the area occupied by UHV AC GIS substations and achieve compact design, the State Grid Corporation of China launched the development work of a voltage transformer for UHV AC GIS (referred to as tank voltage transformer) in 2009 to meet the requirements of 1000kV Huainan - The urgent need for follow-up UHV AC projects such as Shanghai.
Under the comprehensive promotion and unified organization of the State Grid Corporation of China, the State Grid Research Institute of Electric Power and Nisshin (Wuxi) Electromechanical Company respectively initiated the development of capacitive and electromagnetic voltage transformers and achieved major breakthroughs according to the needs of the project. . The State Grid Corporation of China adheres to the principle of safety and reliability first, and conducts rigorous testing and evaluation on the products. The results show that the developed product has stable performance, excellent indicators and a world record.
The State Power Industry Electric Equipment Quality Testing Center (State Grid Institute of Electric Power Wuhan Campus) undertook all test tasks, overcame difficulties and created conditions, and created important conditions for the completion of high-quality research and development on time.
