摘要
针对电力设备在操作冲击电压下产生局部放电现象,构建了油纸绝缘气隙模型,基于局部放电发展过程特征变化,分析了放电重复率和放电量。
The gap mode in oil-paper insulation model and partial discharge measurement system under impulse voltage is established. Based on the partial discharge process characteristics, the discharge quantities and repeatability are researched.
