| 摘 要： | 分析对比了电气几何理论和先导发展模型等各种雷电屏蔽理论的特点 ;介绍了雷击导线时过电压波阻抗分析计算模型以及雷击杆塔波阻抗计算模型和杆塔冲击接地电阻的参数计算公式。认为雷击档间避雷线的情形和线路电压在雷击跳闸率的计算中不能忽视 ,建议开展绝缘子类型和安装形式对雷电闪络特性的影响以及双回线路相关影响因素的研究。

| Abstract: | The factors which influence the lighting strike trip-out rate of transmission line are discussed in this paper. Lightning strike of power line corridor can be reflected by GDF of the influenced area of power line which is calculated with LLS system. The characteristics of different EGM and LPD models are analyzed and compared. The calculation model of conductor and tower surge impedance under overvoltage caused by lightning striking as well as calculation formula of tower surge grounding resistance are introduced. It is believed that the strike on the shielding line of mid-span and voltage level of line should not be omitted in the calculation of lightning strike trip-out rate, and some suggestions about research work are put forward. |
