| 摘 要： | 建立数学模型计算了复合绝缘子的沿面电场分布,利用有限元法计算了220kV线路复合绝缘子不安装均压环及安装不同形状尺寸均压环时沿面场强分布和电位分布。分析了均压环各因素变化对电场分布改善效果的影响,指出环径和罩深对端部电压分布改善效果明显,管径对电场分布改善效果好,根据各因素的综合影响,推荐了220kV复合绝缘子均压环的结构参数。 |
| 关 键 词： | 复合绝缘子 电场强度 电位分布 均压环 |

| Abstract: | Mathematical model of composite insulator is set up,and electric field distribution along the surface is calculated.Based on finite element method,electric field distribution of 220 kV composite insulators,without shielding ring or with different size shielding rings,is analyzed.Then the effects of different structural parameters and shape on electric field intensity and potential distribution of composite insulator are analyzed.At last,some advices on the structural parameters of shielding ring are given. |
| Keywords: | composite insulator electric-field intensity potential distribution shielding ring |
