| 摘 要： | 推导了含悬浮电极时的轴对称结构的有限元方程,并利用该方法计算了550kV六氟化硫终端中有无悬浮电位屏蔽罩时的电场分布。计算表明,终端中采用悬浮电位的屏蔽罩后能有效地降低终端外表面的最大场强,避免了此处空气中局部放电的发生,提高了终端运行的可靠性。

| Abstract: | FE equation of the electric field in axial symmetrical structure employing the suspending electrode was derived and the FEM for analyzing the electric field distribution in the sulfur hexafluoride (SF6) terminations was employed in this paper. A comparison of the electric field in terminations with and without the suspending electrode was presented. The results reveal that a uniform electric field distribution is achievable, partial discharge is avoided in exterior of the terminations, and the reliability of the terminations is improved by employing suspending electrode in terminations. |
