盆式绝缘子内导体及绝缘子表面形状对电场的影响

Influences of electrode and surface structure of disc insulator on distribution of electric field in GIS

用有限元法对SF_6全封闭组合电器（GIS）中的盒式绝缘子处的电场进行了计算．分析了内外屏蔽电极及绝缘子表面形状对电场分布的影响．同时获得了不同情况下的等位线图．进而为GIS中盒式绝缘子的优化设计提供了必要的数据和理论支持．

In this paper the electric field of the disc insulator inside GIS was calculated through thefinite element method. The influence of internal and external shielding electrodes and the shape of theinsulator on the elatric field was analyzed, and at the same time the equal potential line distribution onthe surface were also acquired. It has provided some necessary data and theory support for theoptimism design of the plate insulator in engineeing practice.
