摘要
研究了避雷器安装方式、杆塔冲击接地电阻和输电线路档距对500kV线路耐雷水平的影响,得出了不同情况下通过线路型避雷器的雷电放电电流和冲击吸收能量。
This paper deals with the influence of CMOA installation number,tower grounding resistance&line span distance on the lightning-withstand level of a500kV transmission line.Based upon this,the CMOA discharge cur -rent and impulse energy absorption are detailed for different applications.
