摘要
根据具体的线路杆塔结构 ,采用线路金属氧化物避雷器对 3 3 0 k V线路的耐雷水平进行了计算分析 ;具体比较了安装线路避雷器和未安装避雷器时雷击塔顶及雷击相线的耐雷水平 ;分析了雷电流的波形、接地电阻、档距。
According to the specific structure of towers,the lightning withstanding level of 330kV transmission lines with line metal-oxide arrester(MOA)is analyzed.The lightning withsanding levels under the conditions of lightning strick to the towers or the phase conductors are compared in detail.The effects of waveform of lightning current,grounding resistance,tower span and the technical performance of MOA on the lightning withstanding level are also analyzed.
