Helping "Double Carbon": Haihong Electric successfully developed "Super Class 1" domestic heat-resistant score-oriented silicon steel transformer

Recently, State Grid Smart Grid Research Institute Co., Ltd. (formerly Global Energy Internet Research Institute), Haihong Electric and Baosteel Corporation jointly launched the project "Research on Preparation Technology of Heat-resistant Ultra-low Loss Oriented Silicon Steel and S15 Distribution Transformer". Significant achievements: SB-M·RL-400/10-CNX1 "Super Level 1" three-dimensional wound core transformer was successfully developed by applying Baosteel's self-developed heat-resistant ultra-low loss oriented silicon steel. The product has passed all tests including partial discharge and lightning impact at one time, and all performance indicators are better than the project requirements: Among them, the no-load loss is about 18% lower than the first-level energy efficiency limit value of GB 20052-2020, and the load loss The reduction is about 8%, and the noise level is as low as 32 decibels. This marks the localization of the core technology of heat-resistant scored oriented silicon steel three-dimensional wound core transformer, and reflects the leading level of my country's three-dimensional wound core technology.

General Secretary Xi Jinping recently emphasized that it is necessary to steadily and orderly promote the "dual carbon" work and take the path of green and low-carbon development. The "Super Level 1" three-dimensional wound core transformer adopts the advanced structure of the three-dimensional wound core and the heat-resistant scored oriented silicon steel independently developed by Baosteel. It has excellent performances such as ultra-high energy efficiency, green environmental protection, safety and reliability, and low noise. If all the high-energy-consuming distribution transformers on the grid are replaced with "super-level 1" three-dimensional wound core transformers, more than 115.7 billion kWh of electric energy can be saved every year, exceeding the annual power generation of the Three Gorges Dam in 2021 (103.649 billion kWh), Based on the 30-year life cycle of the transformer, it can reduce carbon emissions by about 7.1 billion tons, save about 1 billion tons of standard coal consumption, and reduce SO₂ emissions by about 100 million tons, which will save the country a lot Electric energy can improve the energy saving and consumption reduction level of the distribution network to a higher level, which is in line with the green development concept of "carbon peak, carbon neutrality".

During the research and development period, Haihong, together with the Intellectual Research Institute and Baosteel, established the selection principle of heat-resistant silicon steel for three-dimensional wound core transformers through the analysis of the characteristics of heat-resistant ultra-low loss oriented silicon steel, and used heat-resistant notches for three-dimensional wound cores. The research on the heat-resistant mechanism and key production technology of silicon steel has broken through the "stuck" dilemma of foreign high-end silicon steel materials, and successfully applied domestic heat-resistant scored oriented silicon steel to three-dimensional coil cores!

Green development, energy saving first, Haihong Electric always adheres to the green and low-carbon development path, and comprehensively promotes the green and energy-saving development of three-dimensional wound iron cores. It has more than 250 patented technologies for three-dimensional wound cores at home and abroad (including 58 invention patents), and its scientific and technological innovation capabilities have obtained Recognized by the Ministry of Industry and Information Technology and other departments, it has successively won the bid for "2020 Green Manufacturing System Solution Supplier", was rated as "2021 Green Manufacturing List-Green Factory", was selected into the "Energy Efficiency Star" Equipment Product Catalogue, etc., developed Produced "Super Level 1" series of energy efficiency products, photovoltaic intelligent double-layer double-male transformer, 110kV three-dimensional wound core power transformer, amorphous alloy three-dimensional wound core traction rectifier transformer for rail transit, primary and secondary fusion intelligent transformer and other international leading products , truly realize "world technology, win glory for the country". In the future, Haihong Electric will actively implement the national "double carbon" strategy, adhere to the sustainable development path of independent innovation, green and environmental protection, create more high-quality goods with the spirit of craftsmanship, contribute to the realization of the national "double carbon" goal, and contribute to Haihong strength。
