摘要为探索冲击电压下气体绝缘开关设备（GIS）悬浮缺陷局部放电检测的有效性及灵敏性,搭建了冲击电压下局部放电试验平台,测量了悬浮缺陷在非振荡冲击波（标准雷电波、标准操作波）、振荡冲击波（振荡操作波）和工频电压下的局部放电信号,提取并分析了悬浮缺陷在不同类型冲击电压波下的局部放电特征谱图,比较了冲击电压波形和工频电压对悬浮缺陷检测的灵敏性。研究结果表明,在非振荡冲击波和振荡冲击波作用下,悬浮缺陷放电稳定、重复性好,冲击电压波对悬浮缺陷的局部放电检测较有效;在不同试验阶段内,振荡冲击电压下的q-φ散点图及N-φ柱状图以及非振荡冲击电压下的q-Δt/Δu散点图和N-Δt/Δu柱状图的形貌特征差别较大,可作为表征GIS悬浮缺陷放电类型及放电严重程度的特征谱图;在三种冲击电压波形中,振荡操作冲击电压波形对缺陷检测灵敏度最高,是工频电压下悬浮缺陷局部放电起始电压的1.3倍。

Abstract：In order to study the detection effectiveness of partial discharge provoked by suspension defect in gas insulated switchgear (GIS) under impulse voltage, the experimental platform of suspension defect under impulse voltage has been set up in the laboratory. The partial discharge signals provoked by suspension defect have been measured, under non-oscillating impulse voltage (standard lightning impulse, standard switching impulse) and oscillating impulse voltage (oscillating switching impulse). The partial discharge characteristics thereafter have been studied. The results indicate that, the partial discharge of suspension defect has high stability and repeatability under the non-oscillating impulse voltage and oscillating impulse voltage, and the impulse voltage waves are effective to detect the suspension defect. As partial discharge exacerbates, shape changes occur in the

Key words： scatter plot and N-φ histogram under oscillating impulse voltage as well as q-Δt/Δu scatter
