【摘要】 对采用金属氧化物避雷器提高110 kV输电线路易击段与易击杆塔的耐雷水平进行了计算分析。比较了安装金属氧化物避雷器前后雷击杆塔与雷击输电线路的耐雷水平;分析了接地电阻、线路挡距等对线路耐雷水平的影响,并用电气几何模型分析了导线雷电绕击。更多还原

【Abstract】 For the sake of increasing the lightning impulse withstand level of 110 kV transmission line, MOA is adopted. The lightning impulse withstand level is thus eal-eulated and compared with and without MOA installation. The influence of grounding resistance ete. on the lightning impulse withstand level is also analysed.更多还原
