摘要：為提高金屬封閉式氣體絕緣組合電器 (GIS) 中支柱絕緣子的耐電性與機(jī)械強(qiáng)度，基于有限元仿真，通過(guò)拓?fù)鋬?yōu)化的方法設(shè)計(jì)了支柱絕緣子內(nèi)部的材料分布，研究了材料相對(duì)介電常數(shù)與楊氏模量梯度分布后絕緣子的電場(chǎng)分布與機(jī)械應(yīng)力場(chǎng)分布特性。仿真結(jié)果表明：經(jīng)過(guò)拓?fù)鋬?yōu)化后，合理的材料參數(shù)選擇可顯著降低絕緣子本體與金屬嵌件所形成的界面處的最大電場(chǎng)強(qiáng)度和機(jī)械應(yīng)力，相較于初始的勻質(zhì)支柱絕緣子，最大電場(chǎng)和機(jī)械應(yīng)力可分別降低 40% 和 20% 以上，為增強(qiáng)支柱絕緣子綜合性能，提高絕緣子運(yùn)行可靠性提供了技術(shù)參考。

Abstract: In order to improve the electrical resistance and mechanical srtength of the post insulator in the metal-enclosed Gas-Insulated Metal-Enclosed Switchgear (GIS), the material distribution inside the pillar insulator was designed by topology optimization method based on finite element simulation,and the electric field distribution and mechanical stress field distribution characteristics of the insulator after the gradient distribution of the relative permittivity and Young's modulus of the material were studied. The simulation results show that: after topological optimization, reasonable material parameter selection can significantly reduce the maximum electric field strength and mechanical stress at the interface formed by the insulator body and the metal insert.Compared with the initial uniform pillar insulator, the maximum electric field and mechanical stress can be reduced by more than 40% and 20% respectively,it provides a technical reference for enhancing the comprehensive performance of pillar insulators and improving the operational reliability of insulators.

Key words: gas-insulated metal-enclosed switchgear; finite element simulation; pillar insulator; electric field distribution; mechanical stress
