摘要
以发电机局部放电在线监测技术应用于小浪底水电厂为例,分析了影响发电机局部放电在线监测系统现场应用效果的因素。结果表明,发电机局部放电在线监测传感器的安装是影响系统现场应用效果的重要因素,基于发电机运行电压分布和结构特点,在发电机出口定子分支汇合点安装传感器,可更准确地定位放电点,从而提高监测效果。
Based on application of generator partial-discharge on-line monitoring in Xiaolangdi H ydropower Plant, factors influencing effect of generator partial-discharge on-line monitoring site application are analyzed. According to structure and operation voltage distribution of generator, sensors installing at converging points of stator can locate position of partial-discharge more accurately, which improves effect of monitoring. The results show that sensors installing is the im portant factor influencing site application effect of generator partial-discharge online monitoring system.
