摘要
针对给粉机在运行过程中频繁跳闸的问题,通过对跳闸现象的记录、统计、分析,认为跳闸的根本原因是煤质差,直接原因是变频器加速时间设置偏短,采用加强配煤管理和通过延长变频器加速时间提高变频器适应性的方法,基本解决了给粉机频繁跳闸问题。
For the trip continually of pulverized coal feeder during operation,through noting,statistic;and analysis on trip phenomena,it is found that the main cause is bad coal,the efficient causes is short acceleration time setting of transducer.The problems are handled by strengthening coal distribution management and raising transducer adaptability through prolonging acceleration time of transducer.
