The trend of environmental protection trends energy-efficient inverter popular market future market demand

In the context of energy conservation and environmental protection, the inverter industry has seen a booming growth trend in recent years. Energy-saving frequency converter has very prominent advantages in terms of technical performance, and China is currently vigorously promoting the popularization stage. With the increasing demand for energy conservation and environmental protection in various machinery industries, the inverter industry with energy-saving effects depends on the green market.

The frequency converter is a high-tech product with high added value and high returns. The initial use of the frequency converter is not for energy saving, but AC drives instead of DC drives and meet the requirements of process control. With the development of automation, power electronics and other technologies, inverters are key equipments for motor speed control and energy saving, changing the old mode in which ordinary motors can only operate at constant speed, making the motor and its dragging load without any changes. That is, the speed output can be adjusted according to the production process requirements, thereby reducing the power consumption of the motor and achieving the purpose of efficient system operation.

National policies have been issued in succession to jointly promote energy conservation. At present, China's energy-saving society concept is actively being promoted. The national government has accelerated the introduction of industrial policies and pointed out the direction for energy-saving development. Power transformers are the key electrical equipment for power transmission. Transformer losses account for 30% to 40% of the power grid losses, while all transformers in China account for more than 3% of the national power generation. 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 clarified the specific goals and investment plans for energy saving and emission reduction during the 12th Five-Year Plan period and required the reduction of power transformer losses during the 12th Five-Year Plan period, in which the no-load loss was 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 the promotion products, the promotion of enterprise conditions, the extension period, the promotion and subsidy standards, the promotion qualification application, the subsidy fund application and the disbursement, and the 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.

Environmental Protection Trends Energy-Saving Converters in a Fashionable Market 2013 is a critical year for the Twelfth Five-Year Development Plan. The government work report puts high demands on energy-saving and emission reduction in industry and the public sector. At the same time, the inverter industry has ushered in a development opportunity. . 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 energy saving rate of the general frequency converter is about 20%-30%, and the highest frequency may even exceed 50%. The energy-saving effect of the frequency converter is closely related to the operating condition parameters of the application environment. The parameters of the motor operating conditions are reasonable, the characteristics of the load changes, and the initial adjustment and speed control methods of the equipment can directly affect the power saving effect of the inverter. With the rapid development of frequency conversion technology and the expansion of product functions, frequency converters have achieved unprecedented development and application in modern industries such as cement, elevators, printing, and power, as well as medicine, communications, transportation, transportation, power, electronics, and environmental protection. All walks of life in the national economy are inseparable from the inverter. According to the 720 yuan/KW price estimate, even without considering the new motor, China's inverter market has reached 73.1 billion yuan, and the development space is very broad.
