The Study Of Green Intelligent High-inverter And The Application Of The Dust Blower In The Steel Iron Mill Of WISCO

Frequency Control Its high efficiency, high power factor, as well as the governor and the activated braking performance, and many other advantages at home and abroad and was recognized as the most promising way of speed. Moreover, China's current energy situation is becoming increasingly important, market competition after China's WTO entry enable enterprises to reduce costs increased the pressure, which is lowering energy consumption with a powerful internal driving force. High-voltage high-power electrical equipment and energy-saving requirements on the use of high-performance inverter so that the requirements of widely used high-pressure metallurgical industry VVVF technology.In this paper, high-pressure VVVF technology and the status quo in the application of the metallurgical industry; the second chapter of the three types of topology of the structure and high-voltage inverter principle; the third chapter of SVM and dual PWM modulation principle is analyzed; the fourth chapter of VVVF and vector control principle, and explains; the fifth chapter introduced a high voltage inverter Perfect Harmony in IRONWORKS WISCO dust blower application, after the calculation of the energy consumption that the high voltage inverter in energy conservation and environmental protection and has obtained good results.
