  5. This can fully consider the effect of the structure of transmission line and the selection of lighting parameter etc. by calculating and analyzing various of factor that affect the lightning tripping probability of 500kv double circuit transmission line, we can draw the conclusions : the result by intersecting method is more accord with the practicality circumstance than by existing standard methods, using unbalance high insulation and reverse sequence of wire can reduce the contemporary outage rate of double circuit line, reducing the footing resistance is one of the most efficiency method to reduce the back stroking rate of double circuit transmission line, the double back stroking rate and the single back stroking rate will fall by three ground wire, when the footing resistance is 10 ohm, the back stroking rate by three ground wire is 83 percent of by two ground wire

    在分析輸電線路繞擊耐雷性能時，對線路的雷電屏蔽問題進行了分析，提出對擊距法進行改進，充分考慮了風速的影響因素，編寫了具有工程實用價值的計算線路繞擊耐雷水平的程序，此方法可以充分考慮線路結構和雷電參數等對繞擊率的影響。通過對影響500kv同桿雙回線路雷擊跳閘率的各種因素進行了計算和分析，得到以下結論：採用相交法的計算結果比定義法更符合實際運行情況。採用不平衡高絕緣方式和導線逆相序排列可以大大降低雙回同時跳閘率。
