摘要
对２２０ｋＶ输电线路采用氧化锌避雷器提高耐雷水平进行了计算分析。具体比较了雷直击杆塔时安装不同支数避雷器时的防雷效果，分析了接地电阻、线路档距等对耐雷水平的影响，同时计算了线路避雷器吸收的雷电放电能量。
Study on adopting ZnO arrestor to increase lightning withstand level of 220kV transmission line is carried on. The influence of some factors, such as number of arrestor, ground resistance of tower and span length of line, on lightning withstand level is analyzed, at the same time, lightning discharge energy absorbed in ZnO arrestor is also considered.
