摘要
文章分析了雷击输电线杆塔时产生的感应过电压通过场线耦合机制对输电线路耐雷水平的影响。分析和仿真计算结果都表明,感应过电压对耐雷水平的影响不可忽略。比较了计算感应过电压的几种典型方法的优缺点后,推荐其中一种简化的方法,并将该方法应用到实际防雷计算中进行了验证。
The influence of induced voltage of lightning stroke to the transmission line tower on the lightning withstand level of transmission line through the field-line coupling mechanism are analyzed. Both the results of analysis and simulation reveal that the effect of lightning induced voltage on the lightning withstand level cannot be negligible. After reviewing several classical methods to calculate the induced overvoltage, one of these methods is recommended for its simplicity and good accuracy, and is integrated with existing EMTP program.
