    摘 要:以提高盆式絕緣子絕緣能力為出發(fā)點,對盆式絕緣子放電現(xiàn)象及電場強度進行仿真,研究了沿面爬距對盆式絕緣子絕緣能力的影響,并對盆式絕緣子進行了優(yōu)化改進。新設(shè)計的盆式絕緣子可以改善凹面?zhèn)冉^緣能力弱于凸面?zhèn)惹闆r,提出將沿面合成場強納入絕緣能力考核范圍,經(jīng)對優(yōu)化后盆式絕緣子進行絕緣試驗驗證,結(jié)果表明絕緣性能優(yōu)異。

    Abstract: This study practiced a simulation experiment for discharge phenomenon and electric field intensity of basin insulators to improve their insulating ability. It also researched the influence of creep-age distance on the basin-type insulator and optimized its quality. The new basin-type insulator can balance the insulation ability of both sides. This paper proposed to include the ability of creep-age synthesized electric-field strength into the insulation to assessment. The result of the experiment shows that the improved product has better insulation ability.
    Key words: basin insulator; insulation design; lightning impulse voltage
