摘　　要：通过对湛江东海地区10 kV架空绝缘导线的调研,分析了架空绝缘导线雷击断线机理,阐述了绝缘导线断线理论计算方法,针对雷击断线问题,介绍国内外常用的5种防护措施及安装范围的说明,并结合东海地区配电线路的具体情况,提出了在架空绝缘线路上安装穿刺型防弧金具或过电压保护器,能够降低雷击断线事故,并且比较经济、有效、可靠。Through investigate and survey 10 kV overhead insulation wires in Donghai area of Zhanjiang city, the mechanism of lightning-caused breaking are analyzed in this paper. Elaborated the theoretical calculation method for broken insulation wires, for the problem of lightning-caused breakage, we introduced five I,：inds of overhead in- sulation wires lightning protection measures and the scope of installation instructions at home and abroad, combi- ning with Donghai area the special conditions of distribution circuit, overhead insulated conductors use of arc-protection hardware with stabs or over voltage protection for the said purpose is presented, can reduce the lightning caused breakage trouble and the lightning protection tool is more economical, efficient and reliable.
