World technology, glory for the country

——Record the delivery of energy-saving and environmentally friendly three-dimensional wound core transformers

　　In the early morning of August 17th, the colleagues of the 132kV project department of Haihong Electric had entered into a tense and orderly working state, preparing for the delivery of SZ-RL-31500/110 three-dimensional wound core transformers for new energy projects, so as to ensure that the products It was loaded smoothly and transported safely to the waste-to-energy project site.

　　Recalling the time back to 2010, Comrade Su Bo, then vice minister of the Ministry of Industry and Information Technology, came to Haihong for investigation and investigation. Minister Su kindly said to Chairman Xu Kaixuan: "Three-dimensional wound core transformers are energy-saving and advanced, and should be upgraded to high-voltage grades. , large-capacity development, and make greater contributions to the country's energy-saving and emission-reduction undertakings." Chairman Xu Kaixuan, who has listened to and followed the party all his life, has since included the research and development of 110kV voltage level three-dimensional wound core power transformers in the company's future development strategy. After full demonstration and feasibility evaluation and analysis by experts, the company's technical team and equipment tooling team, Haihong officially approved the research and development project in 2011: 110kV voltage level three-dimensional wound core power transformer, which was developed and trial-manufactured for supporting prototypes. The company newly purchased 30 acres of industrial land, A new 110kV voltage level three-dimensional wound core power transformer research and development base is equipped with the most advanced research and development and testing equipment in this field, which can conduct routine tests, type tests and special tests.

　　It took 6 years, more than 2,000 days and nights, and invested more than 90 million yuan. The 110kV voltage level three-dimensional wound core power transformer was successfully developed. The trial prototype was submitted for inspection and passed the routine test, type test, and All special tests passed. No-load loss, load loss, no-load current, noise, partial discharge and other performance indicators are better than the national standard. In 2018, Guangdong Mechanical Engineering Society and Guangdong Machinery Industry Association jointly organized a scientific and technological achievement appraisal of "110kV voltage level three-dimensional wound core power transformer". The indicators are at the leading international level. Another SZ-RL-31500/110 product was delivered, marking the launch of the 110kV voltage class three-dimensional wound core power transformer on the market and running on the grid, marking a new era for the development of three-dimensional wound core transformer technology.
