| 摘 要： | 为研究支柱绝缘子表面电场分布特性,经理论分析建立其有限元计算模型,获得了工程设计中所关心部位的电场强度分布。计算了3种典型支柱绝缘子理想情况下表面电场强度分布,并与增爬裙计算结果进行比较分析,结果表明,绝缘子两端电场强度较大,中间部位较低;增爬裙对其电场强度分布的改善没有明显的作用,电力线走向发生一定改变。 |

| Abstract: | To study the external electric field distribution of post insulator,a finite element method calculation model was established by theoretical analysis to obtain the external electric field intensity relevant to engineering design.Finally the electric field distributions in three typical types of post insulators were calculated and compared to those with creepage extender.The results indicated that the higher electric field intensity was distributed on both sides of post insulators and the lower in the middle part.Creepage extender didn't obviously improve the electric field distribution and electric fluxlines have altered to a certain extent. |
| Keywords: | post insulator finite element method creepage extender electric field intensity |
