摘　　要：对35kV单进线的终端变电站,当雷电绕击到进线段导线而侵入变电站时,现有的避雷器保护方式不能满足要求。采用EMTP程序计算得出,应再增加一组避雷器,并在实际中得到应用。In the light of 35kV terminal substation with single incoming line, the current lightning protection mode can not satisfy the requirement when lightning make detour struck on the line and invade in substation. The calculation by using EMTP program shows that it is necessary to add a group of lighting arrestor. And this has been applied in substatioa
