公稱電壓高於1000 v的系統用室內和室外瓷料或玻璃支柱絕緣子的試驗The main work and conclusion for this paper is as following : according to the flashover test results of several kinds of iced insulators under positive voltage and negative voltage, this paper obtained : for the single porcelain insulator, the single glass insulator and the composite insulator bridged completely by icicle, the metal cathode ' s strong ability of emission electron is the primary reason that results in the lower negative flashover voltage ; the position difference of the high resistance district in method anode side results in that porcelain insulator cluster and glass insulator cluster have an evident effect of polarity ; when less ice and no icicle at the brim of the sheds, due to numerous non - polar arcs on the composite surface, the effects of polarity of composite insulator was lost using the test method of the average flashover voltage in the freezing period, dc flashover performances were investigated of several insulators with some typical structures and different material
本文的主要工作和結論如下：在人工氣候室內，根據不同覆冰絕緣子正、負極性下的閃絡試驗結果，得出負極性電弧金屬陰極的強電子發射能力造成了單片瓷、玻璃絕緣子及被冰凌橋接的合成絕緣子有較低負極性冰閃電壓；正極性電弧金屬陽極側產生高電阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的極性效應；覆冰較少時，合成絕緣子表面出現數量較多的非極性電弧使合成絕緣子無極性效應。利用覆冰期內平均閃絡電壓的試驗方法，對不同材質和結構的絕緣子在覆冰、低氣壓和污穢共存環境中的直流閃絡特性進行了研究。試驗結果表明，直流平均閃絡電壓隨著海拔的升高、覆冰量的增加以及污穢度的增加而降低，且其特徵指數與絕緣子結構、覆冰量、覆冰狀態、污穢度等有關。
