摘 要:針對(duì)40.5 kV 固封極柱在生產(chǎn)過(guò)程中因出現(xiàn)絕緣擊穿或澆鑄過(guò)程中環(huán)氧樹(shù)脂漏料造成生產(chǎn)成品率下降的情況,建立真空斷路器模型,對(duì)固封極柱內(nèi)部結(jié)構(gòu)進(jìn)行有限元電場(chǎng)優(yōu)化設(shè)計(jì),并采取在真空滅弧室硅膠層均勻涂抹底涂劑,固封極柱下出線(xiàn)座與真空滅弧室硅膠層之間采用雙重密封結(jié)構(gòu)等方法對(duì)工藝進(jìn)行優(yōu)化。試驗(yàn)結(jié)果表明,優(yōu)化設(shè)計(jì)后的固封極柱提高了產(chǎn)品的合格率及整體性能。

Abstract: The yield of 40.5 kV solid-insulation-embedded poles declined when they had insulation breakdown in the process of production or the leakage of epoxy in the process of casting production. This paper established the vacuum circuit breaker model to carry out finite element optimization design for the interior structure of solid-insulation-embedded poles, with silica gel layer painted over silane coupling agent in vacuum arc-extinguishing chamber, with double seal structure adopted between the outgoing line seat of solid-insulation-embedded poles and the silica gel layer in vacuum arc-extinguishing chamber to optimize technology. The test results show that the solid-insulation-embedded poles optimal designed raises the yield of products and the whole performance.
Key words: insulation breakdown; solid-insulation-embedded poles; electric field; finite element; double seal
