摘　　要：为了研究架设在输电线路周围的架空配电线路的感应雷跳闸概率受输电线路引雷范围的影响,通过结合雷击距的电气几何模型与雷电流幅值概率密度函数计算配电线路的感应雷跳闸率。在引雷范围的基础上,分析不同走向的输电线路与架空配电线路对架空配电线路感应雷跳闸率的影响,对比输电线路架设前后落雷密度的变化计算架空配电线路感应雷跳闸率。In order to study the influence of the adjacent transmission line＇s lightning induction range on the trip-out probability of the overhead distribution lines, this paper combines the geometric model for the lightning stroke dis- tance with the probability density function of the lightning current to calculate the lightning induced trip-out rate of the overhead distribution line. On the basis of the lightning induction range, the research analyzes the influence of the different routes of transmission lines and overhead distribution lines on the lightning induced trip-out rate of the over- head distribution lines. And the trip-out rate is calculated by comparing the lightning density change before and after the erect ion of the transmission lines.
