超细碎高压辊磨机跳车故障原因分析及处理预防

Analysis, Treatment and Prevention of Tripping Failure of Ultra-fine High-pressure Roller Pulverizer

马钢集团南山矿业公司超细碎工程高压辊磨机驱动系统选用了西门子公司生产的中压变频驱动,该系统在运行过程中经常出现跳车故障。叙述了中压变频器系统的基本原理、实际故障处理过程及预防措施。

The driving system of the high-pressure roller mill at the ultra-fine pulverizing project of Ma Steel Nanshan Mining adopted Siemens medium-voltage frequency-changing drive, which often suffered tripping accidents during operation. The basic principle of medium-voltage frequency inverter, actual treatment process of the tripping problem and preventive measures are described.
