Inverter industry develops to diversification

The frequency converter is an important component of the industrial control system and is installed at the front of the motor to achieve speed control and energy saving. The rear of the high-voltage frequency converter is mainly driven by fans and pump loads. The actual energy-saving effect reaches 30% to 60%. In the future, the development of the industry market will benefit from the transformation of large and medium-sized projects; the low-voltage inverter and the control layer and the execution layer equipment will be formed together. Automation control system, its future development will benefit from the upgrade of manufacturing equipment.

Inverters tend to diversify

As a whole, the competition in the inverter industry in China will become increasingly fierce. Because the market is highly tempting, the potential capacity is very impressive, and it constantly attracts new players in the industry. The existing market has formed a certain scale and the development is becoming more and more mature. Future resource plunder and market warfare will be inevitable. With continuous technological advancements, the stability of product quality has been gradually improved, and with the advantages of services and prices, the competitiveness of domestic manufacturers will become stronger.

From the perspective of demand, inverters are gradually becoming more diversified, and the emergence of general-purpose and special-purpose products is to meet the diverse needs of users. In addition, inverter manufacturers also pay more attention to product quality and use safety, and actively seek greater breakthroughs, making the inverter can work well in harsh environments, and ensure the use of safety and the user's normal production.

Energy conservation and environmental protection as a constant theme

China's main motor equipment, such as fans, pumps, and air compressors, meets the highest power requirements in operation. The output power often has a large design redundancy. If mechanical speed control energy is used, it is wasted on the valve and the damper damper. Frequency conversion technology through the power electronic control to complete the speed, drag the motor at the back end to increase the range of speed changes, the effect is more pronounced when the frequency is high. The fans and pumps are the most suitable for installing energy-saving inverters. Compared to low-voltage inverters, high-voltage technology is more widely used in subdivided industries.

Relevant experts compared the effects of several major energy-saving products in electrical equipment, in which the efficiency of the inverter is as high as 30% to 60%. When used, it is only necessary to install it at the front of the motor, and the changes to the original equipment are minor.

The promotion of energy conservation and environmental protection is the driving force for the development of China's inverter industry. Frequency conversion technology is also in the process of changing from speed regulation to energy saving. The Twelfth Five-Year Plan puts forward the upgrading of manufacturing equipment and industrial energy conservation and environmental protection, and establishes the path that the industry development will continue to take the same pace of speed and energy conservation. It is expected that low-voltage inverters will be replaced by automation and import substitution as the main line. Domestic enterprises will focus on the development of control and drive technologies; high-voltage inverters will rely on national energy conservation and environmental protection policies, while the downstream will still rely mainly on the transformation of large-scale industrial equipment such as electricity, metallurgy and cement. Intensification will stimulate localization of high-performance products.
