摘 要:作為氣體絕緣金屬封閉開關設備(GIS)中核心元件,盆式絕緣子絕緣設計關系到GIS整體的絕緣水平。闡述了盆式絕緣子設計思路,對其結構形式進行了分析,結合電場及制造工藝給出最優(yōu)形狀比,提出了盆式絕緣子設計過程中關鍵位置電場校驗判據(jù),并通過試驗驗證了所提出校驗判據(jù)的合理性。
關鍵詞:盆式絕緣子;絕緣設計;雷電沖擊電壓

Abstract: The basin-type insulator as the core component in gas-insulated switchgear (GIS), its insulation design affects insulation level of entire GIS.This paper expounded the design thought of basin-type insulator and analyzed its structural style. Combining with the electric field and manufacturing process, this paper gave the optimal shape proportion and proposed the electric field check criterion of the key location in the design process of basin-type insulator. The test verified the rationality of proposed check criterion.
Key words: basin-type insulator; insulation design; lightning impulse voltage
