    摘 要:針對輸電線路實(shí)際雷電參數(shù)的差異性,提出了差異化防雷概念。選取某一典型220kV輸電線路的雷電參數(shù),基于實(shí)際雷電活動參數(shù)對輸電線路雷擊跳閘率進(jìn)行分段計(jì)算,確定雷擊薄弱點(diǎn),并針對性采取桿塔降阻、加裝線路避雷器、加裝可控放電避雷針等措施,該線路的雷擊事故明顯減少,防雷效果良好。

    Abstract: Aiming at differentiation of transmission line actual lightning parameters, this paper raised the differentiation lightning protection concept. Certain typical 220 kV transmission line’s lightning parameters were selected. This paper carried out section calculation based on actual lightning activity parameters on transmission line lightning trip ratio, determining lightning weak point, and taking pole and tower resistance reduction, adding line arresters, adding controllable discharge lightning rods etc measures. The lightning accident on the line is obviously reduced and lightning protection effect is good.
                 Key words: transmission line; lightning parameter; trip ratio; differentiation lightning protection
