针对油-膜绝缘设备可能出现的3种放电类型，通过搭建脉冲电压下局部放电检测平台，采用局部放电测量方法，研究其局部放电量及放电图谱的变化情况及两种不同老化程度的油-膜绝缘样品局部放电特性。结果表明：油-膜绝缘系统的放电图谱与油绝缘系统放电图谱放电脉冲脉宽明显不同，随着油-膜设备绝缘的老化，会导致局部放电更容易发生，放电量更大。

Aiming at the three type of discharge of power equipment by oil-film insulation,through establishing a partial discharge test platform for pulse voltage,using partial discharge measure method,researches situation changes of the partial discharge value and waveform contraposing the three type of discharge,moreover researches the partial discharge characteristics of two oil-film insulation samples with different aging condition. The result shows that the discharge waveform of oil-film insulation system and oil insulation system are obviously different,with the aging of oil-film insulation equipment,can bring on partial discharge more likely to occur and discharge capacity increase.
