【摘要】 通过模拟试验和理论分析，确认户外干式空心并联电抗器局部表面放电系典型的污湿放电，生成的漏电痕迹，除憎水性涂层为一有效措施之外，顶戴防雨帽、外加防雨假层以及加装均流电极均可显著提高污湿放电电压。更多还原

【Abstract】 Through theoretical analysis and experiment, the paper confirms that the partial discharge on dry type air core shunt reactor’s surface is of typical wet contaminated discharge.In addition to hydrophobic coating which is effective against wet discharge, the rain cap together with damp proof layer and current equalizing electrode are proved effective to increase wet contaminated discharge voltage.更多还原
