  1. Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice

    空氣隙的存在使覆冰絕緣子表面的場分佈發生了明顯畸變,隙上承受了非常高的壓,這使得冰凌尖端的場變得相當強,一旦場達到了暈的起始場,局部放就在這一區域發生,進而產生局部弧並逐發展成整串的閃絡,泄漏迅速大,同伴隨著冰的融化。
  2. The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law, and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles, both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators, and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m. the special exponent n, which show the effects of altitude on the flashover voltage, is various with the type of insulator, icing - states and the surface status of iced insulator etc., and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric

    研究結果表明:在不同海拔高度和等值鹽密esdd下,絕緣子的最低交冰閃壓均隨覆冰量的加而呈指數規律降低;當覆冰量加到一定程度后,最低交冰閃壓隨覆冰量加而降低的趨勢趨于飽和;不同絕緣子串的平均飽和覆冰量及閃絡壓的覆冰量影響特徵指數m均與絕緣子的盤徑和傘距等因素有關;在海拔4000 5500m之,不同等值鹽密esdd和覆冰狀態下,絕緣子的交冰閃壓隨海拔高度的加(氣壓的降低)與p / p0呈乘冪關系降低,氣壓影響特徵指數n與絕緣子類型、覆冰類型、覆冰表面狀況等因素有關;當覆冰量和氣壓一定,絕緣子的最低冰閃壓均隨著等值鹽密( esdd )或覆冰水導率的加而呈乘冪關系降低,並逐趨于飽和。
