Last year was a crucial year for the Twelfth Five-Year Development Plan. The government work report placed high demands on energy saving and emission reduction in industry and the public sector. At the same time, the inverter industry has also ushered in an opportunity for development. In fact, during the 12th Five-Year Plan period, China’s environmental protection investment will reach 3.1 trillion yuan, and the total output value of energy-saving and environmental protection industries will reach 5.3 trillion yuan. As the main force and pioneer of energy-saving emission reduction, there is a huge market in the future. demand.

With the advancement and diversification of user requirements, the functions of frequency converter products are continuously improving and increasing, and the degree of integration and systemization are also getting higher and higher, and special energy-saving frequency converter products have appeared in some fields. Looking at China's inverter market, it has maintained a growth rate of 12% to 15% in recent years. Industry insiders expect that the growth rate of the installed capacity (power) of the upconverter in the Chinese market is actually around 20%, and the potential market space is about 120 billion to 180 billion yuan.

At present, the concept of China's energy-saving society is being actively promoted, and the national government has accelerated the introduction of industrial policies to indicate the direction of energy-saving development.

National policies have been issued in tandem to promote energy-saving construction. Power transformers are the key electrical equipment for power transmission. Transformer losses account for 30% to 40% of power grid losses, and all transformers in China account for more than 3% of national power output. Therefore, the state has been focusing on energy saving and consumption reduction of transformers and has been vigorously promoting energy conservation and emission reduction.

The State Council issued a detailed draft of the “12th Five-Year Plan for Energy Saving and Emission Reduction”, which specifies the specific goals and investment plans for energy conservation and emission reduction during the 12th Five-Year Plan period, and requires the reduction of power transformer losses during the 12th Five-Year Plan period, in which the no-load loss is reduced by 10%~13. %, load loss reduced by 17% to 19%.

The Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology issued the "Executive Rules for the Promotion of Energy-Saving Products Huimin Engineering High-Efficiency Energy-Saving Distribution Transformers" by Cai Jian [2012] No. 854. The “Implementation Rules” divides the scope and conditions of promotion products, promotion of enterprise conditions, promotion deadlines, promotion and subsidy standards, promotion qualification applications, subsidy fund applications and disbursement, and penalties. The promotion product is a three-phase 10 kV application pressure level. Non-excitation regulator, energy efficiency grade 2 and above, rated capacity of 30 kVA to 1600 kVA oil-immersed type and rated capacity of 30 kVA to 2500 kVA dry type transformer.
