摘要
在离线的情况下模拟电机发生各种局部放电的状态 ,利用ICMmonitor局部放电在线监测系统得到其放电量峰值和平均放电电流的直线棒图以及局部放电的特征图等。结合吉林白山发电厂在已运行了近10年的 4号机组上安装ICMmonitor局部放电在线监测系统及试验 ,通过多次实验所测得的第一手数据对发电机的绝缘状态进行了评定。
Simulate offˉline the status of the various partial discharge activities in the insulation system of the generators,we can take advangtage of Partial Discharge Onˉline Monitoring System,known as ICM monitor,to obtain the measurement of peak discharge quantity and average discharge current,typical patˉtern and so on.The Partial Discharge Onˉline Monitoring system has been installed on the No.4unit which has been working for about ten years in Baishan power plant in Jilin province.Measurements were taken after several tests,and the firstˉhand data did help on evaluating the insulation status of the unit.
