摘要
对采用ＺｎＯ避雷器提高１１０ｋＶ线路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，并采用电气几何模型分析了线路雷电绕击，最后给出了工程应用及现场运行情况。
Study on adopting ZnO arrestors to increase lightning withstand level of 110 kV transmission line is introduced in this paper. The some factors, such as the number of arrestors, tower groun ding resistance and length of span affecting lightning withstand level are analyzed, and the electrogeo metrical model of shielding failure of transmission line is proposed. Finally, the situations of practical application and field experience are presented.
