同時利用規程法、行波法、擊距法對輸電線路中不同桿塔型號的耐雷性能分別進行了研究和比較，對影響輸電線路雷擊跳閘率的各種因素進行了分析。Choice of sliding or rocker gear all models are equipped with complex instructions functional spaces
可選擇滑動或搖桿式傳動裝置所有型號均配備復位跳閘指示功能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。Obtained by emtp program and the egm, this paper studies on lightning protection performance on 500kv double circuit transmission line the distributed parameter model of tower is built when analyzing the back stroking lightning protection performance for double circuit line, it can truly reflect the spreading course of lightning current on the tower, furthermore, considering the randomness of working voltage ' s phase when lightning strokes the top tower and supposing the probability of lightning appearing arbitrary phase in a cycle of ac is equal, this paper brings forward the statistical method to calculate the rate of back stroking on double circuit line
本文利用emtp程序、擊距法對500kv同桿雙回線路的耐雷性能進行了研究。在分析同桿雙回線路的反擊耐雷性能時，建立了桿塔的分佈參數計算模型，此模型可以真實地反映雷電流在桿塔上的傳播過程。並針對雷擊塔頂時，導線運行電壓相位角的隨機性，本文假定雷擊出現于交流一周期的任一角度區間內的概率相等，提出了利用統計法計算同桿雙回線路的反擊跳閘率。The investigation reveals that, the adoption of moa on segments of 35kv weiyu lines apt to lighting strike would improve the lightning withstand level to 2 - 4 times, and would heavily reduce the stripping outrage
研究表明僅在35kv魏玉線路易擊段桿塔上加裝線路型避雷器后可提高各種情況下的線路耐雷水平2至4倍，並可大大降低線路雷擊跳閘率。For the great amplitude, oscillation and long time lasted, galloping tends towards evoking the nasty accident of inter - phase shortcutting, damage to fitting and supporting structures, causing short - circuiting, conductor burned, hold down towers, and conductor broken, which engender serious economy damage
因為舞動的幅度大，有擺動，一次持續很長時間，因此容易引起相間閃絡、金具損壞，造成線路跳閘停電或引起燒傷導線、拉倒桿塔、導線折斷等嚴重事故，從而造成重大經濟損失。It is importance to accurately conform the wave impedance of tower, when the wave impedance of tower change sign 10 percent independently, the back stroking rate of transmission line will change sign 20 percent accordingly
正確確定桿塔的波阻抗是很重要的，當桿塔的波阻抗獨立地變化10 %時，輸電線路的反擊跳閘率將相應地變化約20 % 。分享友人
