摘　　要：计算分析和具体比较了安装氧化锌避雷器 (MOA)前后 110 k V输电线路易击段与易击杆塔的耐雷水平 ,分析了接地电阻、线路档距等对线路耐雷水平的影响 。This paper analyzes the improvement of lightning withstand level of vulnerable towers and lines at 110 kV transmission lines with MOA through evaluation. The lightning withstand level of tower or transmission line with MOA is compared with the withstand level of those without MOA. Then the effect of grounding resistance and line distance etc on withstand level is analyzed. At the end the problems of shield failure of line are discussed with geometric model.
