摘要
为了研究直流电压下气体绝缘金属封闭开关设备GIS(Gas Insulated Switchgear)在金属球微粒缺陷时检测局部放电的情况,建立了一个采用同轴平板电极为模型的直流脉冲电流检测系统。采用该系统观察金属微粒在电场中静止与跳动时脉冲电流的变化,提出一种金属微粒缺陷的脉冲电流特殊检测法。
In order to study metallic particles defects＇ s partial discharge detection on the DC voltage in the gas-insulated switchgear, DC pulse current detection system of coaxial plate electrodes model is established. Using this system the change of pulse current on metallic particles still and beating in an electric field, and it is proposed a metallic particles defects＇ s the pulse current special detection method.
