摘　　要：基于感应电荷准静法开发了用于特高杆塔雷电过电压分析的计算软件。用该软件计算了两种典型雷电 流波形下江阴特高杆塔绝缘子串两端的电压,并分析了组成过电压的两个分量的影响。计算结果与工程算法基本吻合,证明该软件可用于评价特高杆塔绝缘系统的雷电特性。On the basis of the quasi-steady induced charge method, a software for analysis of lightning over-voltage on ultra-height transmission towers is developed and applied to the Jiangyin ultra-high transmission tower. By this software, the voltages on the two terminals of insulator string on Jiangyin ultra-height transmission tower are calculated under two typical lightning current wave. The influence of two components of over voltage is analyzed. The voltages calculated by the software agree with that obtained by engineering method. It is proved that the software can be used to evaluate the lightning performance of insulation system of ultra-height transmission towers.
