摘 要:根據(jù)污耐壓法提出了±1 100 kV 直流棒形懸式復(fù)合絕緣子外絕緣設(shè)計(jì)的一種方案,并基于有限元法建立了棒形懸式復(fù)合絕緣子的仿真模型,確定了復(fù)合絕緣子均壓環(huán)的結(jié)構(gòu)參數(shù)。仿真結(jié)果表明,該均壓環(huán)設(shè)計(jì)滿足各部分電場(chǎng)強(qiáng)度均低于電暈起始電場(chǎng)強(qiáng)度的要求,有效地改善了復(fù)合絕緣子電位、電場(chǎng)分布,且均壓環(huán)表面不會(huì)產(chǎn)生電暈。

Abstract: According to the pollution withstand voltage algorithm, this paper proposed a kind of plan for ?11 00 kV DC rod suspension composite insulator external insulation design. The simulation model based on finite element method was built for rod suspension composite insulator to determine structural parameters of composite insulator grading ring. Simulation result shows that the grading ring design meets the requirements of every part electrical field strength all bellow electric halo starting electric field strength, which effectively improves composite insulator electric potential, electric field distribution, without electric halo generated in grading ring surface.
           Key words: composite insulator; finite element method; pollution withstand voltage algorithm; grading ring optimization
