主轧机同步电机定子铁芯齿压板松动处理技术

Treatment Technology for Loosening of Tooth Support on Stator Core in Synchronous Motor of Main Rolling Mill

针对攀钢集团攀枝花钢钒有限公司冷轧厂3#主轧机电机定子铁芯齿压板松动缺陷问题,根据现场故障现象进行技术分析,制定了专项检修方案,实施后取得了预期效果。结果表明,检修上线后,电机未再发生齿压板松动引发电机故障的情况,保证了电机正常稳定运行,保障了生产顺利进行。

In terms of the loosening of the tooth support on stator core in synchronous motor of 3# main rolling mill in Panzhihua Steel Vanadium Co.,Ltd., the technical analysis were carried out according to the on-site conditions of the failed support. And then the special maintenance scheme were determined. After maintenance the expected results were obtained. The results showed that the loosening of the tooth support which caused the motor failure never occurred after on-line maintenance. So the motor in normal and stable operation was guaranteed and the production was also in smooth condition.
