VFD’s industrial energy-saving advantages promote industrial upgrading

Industrial energy efficiency is becoming one of the core industries. Because of the frequency converter products feature flexible governor, in the field of electric power saving obvious advantages. From the current development trend, the industry will continue to follow the path of the drive speed energy development.
The variable frequency drive inverter is an important component of equipment industrial control system, installed in the front end of the motor to achieve the speed and energy. The rear end of the main drag high-voltage inverter fan, water pump class load, the actual energy-saving effect of 30% to 60%, the industry will benefit from the future development of the market transformation of medium-sized projects; low-voltage inverter and control layer and execution layer device composed automation and control systems, which will benefit the future development of the manufacturing sector "equipment upgrade."
Variable frequency drive obvious advantages for industrial applications industrial planning second five clear
Ac frequency converter technology was first used on variable speed motor by controlling the on-off semiconductor devices changes the output frequency to achieve the back-end drag AC motor soft start, frequency control and improve running accuracy and implement over current , overvoltage, overload protection.
Compare last mechanical speed control, frequency control of wide range, up to 100% to 5%; high-control precision can reach ± ​​0.5%; because it is stepless speed control, soft start the motor can be realized and the entire production system automatic control, thereby reducing the impact on power.
Experts compared the effect of electrical equipment in several major energy-saving products, which drive efficiency up to 30% to 60%, just install the motor when used in front-end, small changes to existing equipment.
Thus, in the "five" plan proposed upgrade manufacturing equipment and industrial energy saving projects, we established the future development of the industry will take the "speed control simultaneously," path. Down to products, is expected to automate the transformation of low-voltage inverter and the main line of import substitution, domestic enterprises will focus on developing control and drive technology; high-voltage inverter rely on national energy saving policy, the downstream is still electricity, metallurgy, cement and other large industrial equipment transform-based, high-performance products will stimulate competition domestically speed. For more information, please visit http://www.rendapower.com.
