With the upgrading of the overall level of domestic manufacturing, cost consciousness has gradually become the consensus of various industries, because this is directly related to the survival and development of the company. Since the electric drive is the main energy-consuming device in the manufacturing industry, the space occupied by the control cabinet is also relatively large. Therefore, the choice of the drive technology for the enterprise also determines the level of production cost. In addition, “ energy-saving wind †is prevalent in the world, and the inverter is This demand has gradually developed.
Textiles, elevators and other industries are the traditional industries of inverter applications. With the guidance of the development directions of these traditional industries, many new features have appeared in the application of frequency converters. In these fields, the inverter products at home and abroad can be described as “a hundred schools of thought contend †and the competition is very fierce. How to stand out in the “ Red Sea market †, the inverter manufacturers have been painstakingly engaged in new technologies and concepts.
Low-carbon era promotes rapid development of domestic inverter market
The development of a low-carbon economy has become a global consensus. Saving energy, reducing consumption, and building a resource-saving, environment-friendly society have become an eternal topic in today's social development. In the wave of this green revolution, the energy-saving link is very marginal economic benefits and promotion value. Compared with the lower proportion of clean energy sources at the global energy supply side and higher marginal cost, energy conservation is still the most popular and marginal economic benefit area in the green revolution.
Motor energy consumption accounts for a high proportion of energy-saving potential. Through the frequency conversion and speed regulation of the motor, the average energy saving can be more than 30% , the energy saving effect is remarkable, and the motor energy saving space is huge. With the promotion of energy-saving policies, the inverter industry will usher in a new round of development. According to forecasts, the potential energy-saving market in China has reached 800 billion yuan. However, there is still a certain gap between domestic inverters and foreign inverters. The arrival of the energy-saving era will promote the rapid development of the Jianai inverter market.
Where is the gap between us and foreign inverter companies?
First of all, it is difficult to develop technology. At present, many inverter manufacturers in China are investing large amounts of manpower and material resources in the research and development of high-voltage inverters, and strive to occupy the commanding height in frequency inverter technology. In spite of this, the core components of the inverter have always depended on imports, which has become a bottleneck restricting domestic production of the inverter.
Secondly, the inspection period is long, domestic enterprises have a short history of development, and inverter products generally have a maturation period of about 3 years. The quality is reliable and the performance is stable. It requires the customer to use the time test. Since most local companies have not established a long history, the product line is still improving. Many new products have a shorter time to market, and it is difficult to compete with long-established international brands in terms of product maturity and brand awareness. In addition, due to the special nature of China's low- and medium-voltage inverter market, foreign brands are pre-emptive, which has a negative impact on domestic brands participating in market competition.
In addition, the product performance index is low, in the initial stage of the domestic brand start, there are indeed some product quality, but the reliability and stability is poor, affecting the reputation of domestic brands. In recent years, with the growth of local companies and the improvement of their overall strength, the reputation of domestic brands has been significantly improved. However, to completely change the overall impression of users, it still needs the efforts of production companies and the test of time. In product price, brand, performance, after-sales service, delivery date and other factors affecting the purchase of domestic inverter products, product performance indicators become the preferred element. Therefore, improving product performance, especially improving the energy efficiency of products, has become an important task for all production companies.
With the advancement of domestic manufacturers' technological progress and quality stability, coupled with the advantages of services and prices, it is expected that the market situation of high-end products monopolized by foreign manufacturers in the next few years will change.
Inverter " Blue Ocean Innovation " considers industry demand
The inverter application area is not only the elevator and textile industries, but its development represents the technical progress in the entire drive control field.
In the elevator industry, inverters will develop into large-capacity areas, and low-power applications will become more common; the power consumption of power devices and inverters will become smaller and smaller, and the energy efficiency of inverters will increase. With energy feedback The frequency converter of function will be popularized gradually in the field of elevator, the frequency converter of the application of large-scale energy storage device such as super capacitor will also appear in the frequency conversion drive field of the lift. Lu Heqing believes that in the textile industry, frequency conversion and drive technology are currently moving toward new technologies such as multi-axis synchronous drive drives and fieldbus networked control. A frequency converter has been able to simultaneously control multiple axes for precise synchronous operation. However, it cannot be ignored that there is still a certain failure rate during long-term operation, and its stability and reliability still need to be improved.
The inverter industry is being greatly promoted by the low-carbon industry, but the needs of various industries should be taken into consideration. It is the truth to innovate on the basis of the industry.
