Application of High Voltage Frequency Converter in Dust Removal Fan

According to flue gas temperature of arc furnace,the motor speed is set to different stages on the basis of not affecting the furnace dedusting effect.Motor speed control uses the high voltage frequency converter with vector control and energy feedback technology.This frequency converter has the advantages of a constant torque,high speed regulation precision,wide speed regulation range.Frequency conversion reconstruction of the dust removal fan makes power consumption of the system decrease significantly.Power saving rate is over 35%.
