摘要
作用于线路绝缘上的雷电过电压波远非标准雷电波。用先导发展模型方法作为绝缘闪络判据，用于三峡５００ ｋＶ 双回同杆并架出线方案防雷性能的研究，并与其它闪络判据及其计算结果作了比较。
The lightning surges experienced on the line insulation are far from standard lightning impulse waveform. The leader development model has been adapted for the insulation flashover criterion for the study of the lightning performance of the outgoing double circuit lines of the Three Gorges Power Station. The criterion and other criteria usually used and the calculated results are compared and discussed in the paper.
