发电机气隙距离、磁场强度和轴电压的在线监测

On-line Monitoring of Generator Gap Distance, Magnetic Field Strength and Shaft Voltage

本文结合一台实际的水电机组多参数状态在线监测与诊断系统,对发电机的轴电压、气隙距离和气隙磁场的实测情况进行了详细论述。该系统已在福建省某水电厂投入运行。

This paper discusses in detail the test results of generator shaft voltage,gap distance and gap magnetic field,using a multiparameter online condition monitoring and diagnosis system on practicalhydroelectric units. This system is already in service for a water power plant. 
