摘　　要：通过选取避雷器本体参数和串联间隙设计,对电缆线路的冲击特性长度l0和绝缘配合进行计算研究,研制出66 k V带串联间隙金属氧化物避雷器,可与66 k V电缆过电压绝缘保护相配合,正常运行状况下该避雷器是免维护的,并对电缆加以保护。The paper calculated and researched the length of cable lines l0 and insulation properties by selecting arrester body parameters and designing series gap,developed 66 kV MOA with series gap,which can be compatible over-voltage protection with 66 kV cable. The arrester is maintenance-free under normal operating conditions,and could protect cables.
