摘　　要：大红山铜矿竖井提升机系统设计于2007年,按当时传动装置的性价比,采用直流电动机传动系统。直流电动机传动系统交流变直流的整流过程中,产生谐波较大电流。系统采用了降低谐波电流的措施,并经实际运行的检验,满足了国标《电能质量公用电网谐波》要求。The vertical shaft winder system of Dahongshan Copper Mine was designed in 2007. According to the cost performance of the transmission device at that time,a DC motor drive system was adopted. In the rectification process of the AC-DC converter of the DC motor drive system,a large harmonic current is generated. The system adopts measures to reduce the harmonic current,and after actual operation inspection,it meets the requirements of the Chinese national standard "Quality of electric energy supply Harmonics in public supply network".
