The analysis and investigation of the frequency converter industry shows that the domestic inverter market is developed with foreign brands, and the foreign brands are predominant, and the current market share in the domestic inverter market is about 7. The history of most local enterprises is not long, and many products have a short time to enter the market. It is difficult to compete with international famous brands in terms of product maturity and brand awareness.
The frequency conversion industry is a bridge for grafting heavy equipment and production technology, and is an important medium for realizing industrial automation and informatization. With the progress of science and technology, from life to production, from civil to industry, from frequency conversion air conditioning to high-speed train, even to the electric automation control field of industrial and mining enterprises, frequency conversion is omnipresent and the effect is getting better and better. To a great extent, we have entered the times of frequency conversion, and the space of changing frequency to create value is becoming more and more big.
Experts in the industry have introduced that the device that transforms the alternating current with fixed voltage and frequency to alternating current with variable voltage or frequency is called frequency converter. Test data show that the power saving rate of the motor system using inverter is about 30%, which can reach 40%-60% at some high occasions, and the energy saving effect is remarkable. The inverter has become the development direction of motor energy saving.
Experts also said that if China's related industries vigorously promote the use of frequency conversion technology, from technical transformation, technological innovation to the new project design, high performance and high stability high-end industrial inverter, will create huge space for energy conservation and emission reduction of related industries in China.
In recent years, due to the requirements of energy shortage and production technology, high voltage variable frequency speed regulation has become the only way for large production enterprises to save energy, and the demand of the domestic high voltage variable frequency speed regulation market is rising rapidly. The State Council's 12th Five-Year energy conservation and environmental protection industry development plan also explicitly proposed that the motor and drag equipment should be vigorously promoted and other technologies and equipment to improve the overall operating efficiency of the motor system.
Experts believe that in the next few years or even longer, the development trend of China's economic transformation and improving the quality and efficiency will provide more space for the growth of the frequency converter market.
Statistics show that China's inverter market is currently in a period of rapid growth, and has been widely applied in textile machinery, air conditioning, elevator, metallurgy and other industries. In recent years, China's frequency converter market has maintained a growth rate of 12% to 15%. It is expected that at least in the next 5 years, the demand for the frequency converter market will remain more than 10%. The potential market space of the converter in China is about 120 billion to 180 billion yuan.
