摘要

介绍了作者绘制的伊朗等地地图。对伊朗国家电网400kv线路塔底电阻进行了统计分析。根据获得的keraunic水平和塔基电阻的概率结果，已经尝试评估伊朗400 kV绝缘子的闪电50%击穿电压(V/sub 50/)。文中还比较了伊朗输电系统中现有400 kV线路绝缘子的V/sub 50/计算值和V/sub 50/计算值。

The evaluation of fifty percent breakdown voltage across Iranian 400 kV transmission line insulators

The Iranian isokeraunic map developed by the authors is presented. A statistical analysis of tower footing resistances of 400 kV lines in the Iranian national grid is also presented. An attempt has been made to evaluate lightning fifty-percent breakdown voltage (V/sub 50/) across 400 kV insulators in Iran, according to obtained keraunic levels and probabilistic results of tower footing resistances. A comparison between calculated V/sub 50/ and V/sub 50/ of presently installed insulators of 400 kV lines in the Iranian transmission system is also presented.<>
