The preparation and implementation of electrical technical scheme for variable-frequency renovation of sintering main exhaust fan electronic control system of Shougang Jingtang are introduced.The electric control equipment and production operation status of the existing sintering main exhaust fan motor is introduced,and under the background of full utilization of existing electric control equipment,the renovation design scheme of adoption the high-voltage frequency converter control is put forward.This technical scheme covers the four aspects of technical contents such as 10kV distribution system,synchronous motor excitation,high-voltage frequency converter and automation system,so as to realize the switch in the three following operation modes such as the frequency converter start+frequency converter operation,frequency converter start+power frequency operation and frequency converter soft start+power frequency operation.The practice shows that this technical scheme has obtained good social and economic benefits.
