Low carbon era and energy-saving policies promote the rapid development of domestic inverter market

China's inverter industry is facing a revolutionary development and change

data shows that in recent years, China's inverter market has maintained a growth rate of 12% - 15%, and it is expected that the market demand for inverters will continue to maintain a growth rate of more than 10% in at least the next five years. After 10 years, the inverter market can be saturated

stimulated by the huge market demand, the growth rate of China's high-voltage inverter market is particularly noteworthy. According to the statistics of frequency converter branch of China Industrial Electrical Appliances Association, in recent years, the annual demand of frequency converter Market in China has formed a market space of about 10billion yuan. Moreover, with the diversification of user needs, the functions of domestic inverter products are constantly improving and increasing, and the degree of integration and systematization is also getting higher and higher, and some special inverter products have appeared, which has laid the foundation for the further expansion of China's inverter market. In 2005, the market scale of high-voltage inverter was about 1.09 billion yuan, while in 2008, it has reached 3.4 billion yuan

in the face of such a high development speed, people can't help asking why the inverter industry will usher in such a spring? This is due to the low-carbon era and the national energy conservation policy

frequency conversion promotes energy conservation

speaking of frequency converters, people can't help thinking that the new type of bus frequency conversion energy-saving and environmental protection air conditioner that has recently made a great splash in the Expo Park has overcome the defect that the traditional bus air conditioner only doesn't understand the installation process of the oil cylinder and has a single cooling mode, and has become a leader in energy conservation and emission reduction

it is understood that the high-voltage inverter does have a significant energy-saving effect. Without replacing the host equipment, only changing the speed can achieve an average power saving effect of 30%. At present, there are three ways to adjust the speed of the motor, namely, mechanical speed regulation, cascade speed regulation and variable frequency speed regulation. Among them, variable frequency speed regulation technology is the best speed regulation technology. Its speed regulation range is the widest, which can reach 100% - 5%, and the speed regulation accuracy is the highest, which can reach 0.5%

"automobile is more advanced

the professional organization estimates that the total installed capacity of electric motors in China has reached more than 500million kW, and the annual power consumption has reached 800billion ~ 100billion kwh. If all electromechanical production enterprises in the country produce electromechanical products with frequency conversion function, the cumulative power savings in the next 15 years will be 2800 billion kWh (the annual power generation of the Three Gorges power station is only about 85billion kwh, equivalent to saving two Three Gorges power stations in a year) Save 1.43 billion tons of coal, reduce 20million tons of sulfur dioxide and 700million tons of carbon dioxide. At the same time, it can also save 800 billion to 100 billion yuan of power investment. It can be seen that driven by the imperative of low-carbon economy, the growth of China's High-voltage Inverter in the future can be expected

there is a significant gap between Chinese and foreign products

according to the second China inverter and servo motor user survey conducted by the Institute of industry and Market Research of the Institute of mechanical industry information, the top ten inverter and servo motor brands that are most popular with users and have the largest coverage in the Chinese market, including XIMENZI, abb, Mitsubishi and other brands. At present, the domestic brand share of frequency converters in the domestic market is only 25%. What is the gap between us and foreign inverter enterprises

first of all, it is difficult to develop technology. At present, many domestic frequency converter manufacturers have invested a lot of human and material resources in the research and development of high-voltage frequency converters, and strive to occupy the commanding heights in frequency converter technology. Nevertheless, the core components of the frequency converter always rely on imports, which has become the bottleneck restricting the domestic production of the frequency converter

secondly, the inspection period is long, the development history of domestic enterprises is short, and the inverter products generally have a maturity period of about 3 years. Whether the quality is reliable and the performance is stable, and the inspection plastic that needs the customer's use time has always been a difficult test in environmental governance. Because most local enterprises have not been established for a long time, their product lines are still improving, and many new products have entered the market for a short time, it is difficult to compete with international famous brands with a long history in terms of product maturity and brand awareness. In addition, due to the particularity of China's medium and low-voltage inverter market, foreign brands are primarily preconceived, which has an adverse impact on domestic brands' participation in market competition

moreover, the product performance index is lower than the n-constant. In the early stage of domestic brands, there are indeed some products with poor quality, poor reliability and stability, which affect the reputation of domestic brands. In recent years, with the growth of local enterprises and the improvement of comprehensive strength, the reputation of domestic brands has been significantly improved, but it still needs the efforts of production enterprises and the test of time to completely change the overall impression of users. Among the factors that affect users' purchase of domestic inverter products, such as product price, brand, performance, after-sales service, delivery time, etc., product performance indicators have become the preferred factors. Therefore, improving product performance, especially improving the energy-saving efficiency of products, has become an important work for all production enterprises

expert analysis: with the technological progress of domestic manufacturers and the improvement of quality stability, coupled with the advantages in service and price, it is expected that the market situation in which high-end products are monopolized by foreign manufacturers will change in the next few years

industry insiders predict that the new generation of frequency converters should have the following characteristics: first, they are fully digitalized and have complete functions, which can compensate for load changes, especially distributed ones with communication and networking functions and programmable functions. The second is the simple or industry-specific frequency converter and the realization of electromechanical integration and miniaturization. The third is networking and systematization. The production cost is reduced through networking. Through the fieldbus module, different types of frequency converters are configured with the same programming language and communication protocol
