摘要
为改善SF6 气体绝缘电流互感器外电场的分布 ,采用了电容锥结构。本文提出了电容锥的计算方法并对 330kVSF6 气体绝缘电流互感器放置电容锥前后的外电场建立计算模型进行数值计算 ,分析了电容锥对互感器外电场的改善情况。
To improve the distribution of external electric field of SF 6 gas insulation current transformer, cone capacitor is used. The calculation method of cone capacitor is presented in this paper. The calculation model of the external electric field after and before setting cone capacitor in 330kV SF 6 gas insulation current transformer are established and the numerical calculation is taken. The improvement of cone capacitor on the distribution of external electric field of the current transformer is analysed.
