摘　　要：莱钢集团矿山建设有限公司60万t球团厂的窑尾小车电气传动系统采用电磁抱闸进行机械制动,摩擦片磨损快,停车时,窑尾小车时常出现振动和打滑等不稳定问题。文章分析了窑尾小车电气传动系统不稳定的原因,采用变频调速的直流制动功能新方法,选用施耐德电气公司的ATV71系列变频器,构建了新的电气传动系统,有效地克服了摩擦片磨损和电磁抱闸制动延时问题。实际应用表明,该系统运行可靠稳定、稳定,解决了窑尾小车振动和打滑问题。Lai Wu Steel Group Mining Construction Company 600000 tons of pellet plant of kiln car electric transmission system using electromagnetic brake mechanical brake,friction wear quickly,parking,kiln car often vibration and slip instability problem.This paper analyzes the kiln car electric drive system causes of instability,using variable frequency speed regulation of the DC braking function of the new method,selection of Schneider electric company ATV71 series inverter,to build a new electric transmission system,effectively overcome the friction plate abrasion and electromagnetic brake brake problems.Practical application shows that the system is reliable and stable,solve the kiln car vibration and slippage problem.
