摘要
1992年1月马头发电厂4号机6号轴承发生异常振动,高负荷时轴向振动最大曾超过300μm。经过一系列试验分析,确认引起振动的原因是发电机转子出现匝间短路。经处理后恢复正常。本文介绍了这次诊断工作,并绘出了主要试验数据。
The NO. 6 beating of the NO. 4 turbine generator unit of Matou Power Plant experienced an abnormal vibration inJannuary 1992, the maximum axial level of which at higher load once exceeded 300nm.It was confirmed through a seriesof testing and analysis that the vibration was caued by the interturn short circuit of generator rotor. Presented in this paperare some of the main testing data and diagnosing work.
