| 摘 要： | 局部放电造成绝缘劣化的机理是非常复杂的。为了研究局部放电各宏观参数与绝缘电老化寿命的关系,本文应用以微机为基础的局部放电多参数测试系统,测量绝缘体在电老化过程中三种不同类型的局部放电(人工气隙、电树枝、液—固复合体的放电)。试验结果表明:放电能量或功率与绝缘的劣化关系较为密切,它是评定局部放电对绝缘损害更为合理的参数。

| Abstract: | The degration mechanism of insulating material due to partial discharge is very complicated A microprocesser-based P.D.multi-parameters measuring system is us- ed to investigate the relation between the different partial discharge parameters and insulation damage in three different insulation systems(artifacial voids.XLPE electr- ical treeing propagation as well as liquid-solid composite system).The results suggest that partial disacharge energy or power(W_m,W.or P)be a reasonable parameter to evaluate partial discharge activities and closely relevant to insulation degradation. |
