【摘要】 通过测量复合绝缘子电压分布及冲击电压试验 ,研究了不同结构、尺寸的均压装置在不同安装方式下对复合绝缘子电气性能的影响 ,认为圆形均压装置、较深的罩入深度、较大外径可明显改善复合绝缘子电压分布 ,但设计时应保证必要的干弧距离。更多还原

【Abstract】 The influence of different field grading fittings with different installation on composite insulator electrical performance is investigated. The voltage distribution is measured and lightning impulse tests are performed. It is put forward that the voltage distribution of composite insulator is obviously improved by rotundity fittings, larger shielding depth and diameter with enough arc distance.更多还原
