The development of the environmental protection industry increases the demand for energy-saving VFD (Variable-frequency Drive)

With the progress and diversification of user needs, the functions of VFD (Variable-frequency Drive) products are constantly improving and increasing, and the degree of integration and systematization is also getting higher and higher, and there have been special energy-saving VFDs (Variable-frequency Drive) in some fields. frequency Drive) products.

2013 is a very critical year for the 12th Five-Year Development Plan. The government work report puts forward high requirements for energy conservation and emission reduction in the industrial and public sectors. At the same time, the VFD (Variable-frequency Drive) industry is also ushering in a good opportunity for development. In fact, during the 12th Five-Year Plan period, Chinese investment in environmental protection will reach 3.1 trillion yuan, and the total output value of the energy-saving and environmental protection industry will reach 5.3 trillion yuan. As the main force and pioneer of energy-saving and emission-reduction, high-voltage VFD will There is a huge market demand.

With the progress and diversification of user needs, the functions of VFD (Variable-frequency Drive) products are constantly improving and increasing, and the degree of integration and systematization is also getting higher and higher, and there have been special energy-saving VFDs (Variable-frequency Drive) in some fields. frequency Drive) products. Looking at Chinese VFD (Variable-frequency Drive) market, it has maintained a growth rate of 12% to 15% in recent years. Chinese industry insiders predict that the growth rate of VFD (Variable-frequency Drive) installed capacity (power) in the Chinese market is actually about 20%, and the potential market space is about 120 billion to 180 billion yuan.

At present, the concept of Chinese energy-saving society is being actively promoted, and the Chinese national government has accelerated the introduction of industrial policies to point out the direction for energy-saving development.

Chinese national policies have been issued one after another to jointly promote energy-saving construction

Power transformers are key electrical equipment for power transmission. Transformer losses account for 30% to 40% of power grid losses, and all transformer losses in China account for more than 3% of the country's power generation. Therefore, the Chinese state has been focusing on the energy saving and consumption reduction of transformers, and vigorously promotes energy saving and emission reduction.

Chinese State Council issued a detailed draft of the "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction", which clarified the specific goals and investment plans for energy conservation and emission reduction during the Twelfth Five-Year Plan period, and required the reduction of power transformer losses during the Twelfth Five-Year Period, among which the no-load loss was reduced by 10%~ 13%, and the load loss is reduced by 17% to 19%.

The Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology issued Cai Jian [2012] No. 854 to issue the "Detailed Implementation Rules for the Promotion and Implementation of High-efficiency Energy-Saving Distribution Transformers for Energy-saving Products and Benefiting the People". The "Implementation Rules" are divided into 7 parts: the scope and conditions of promotion products, the conditions of promotion enterprises, the promotion period, promotion subsidy standards, promotion qualification applications, subsidy fund application and appropriation, and penalties. The promotion products are three-phase 10 kV application voltage level, Non-excitation voltage regulation, energy efficiency level 2 and above, oil-immersed transformers with a rated capacity of 30 kVA-1600 kVA and dry-type distribution transformers with a rated capacity of 30 kVA-2500 kVA.
