摘要/Abstract

摘要：输电线路的击杆率不仅与地形、杆塔高度、结构有关，而且与雷电流的幅值和概率有关，直接影响到线路雷击跳闸率计算.比照规程推荐的击杆率，应用电气几何模型原理，探讨了线路平均击杆率.

Abstract: For transmission lines,the rate of lightning striking against poles directly affects the calculation of lightning trip-out rate.The former has not only relations to the topographic features,height and structure of poles but also to the amplitude and probability of lightning current.According to the rate recommended by “code”,the mean rate of lightning striking against poles of transmission lines is discussed with an electrogeometric model.

Key words: power transmission lines, lightning striking rate against poles, striking distance
