摘　　要：架空绝缘导线比普通架空裸导线的绝缘和防腐性能好,而与埋地电缆相比在投资、施工及维护方面都有明显的优越性,因此在我国城市电网现代化建设的过程中得到越来越多的应用。但随着城市架空线路绝缘化程度的提高,绝缘导线的雷击问题也趋于严重。首先探讨了绝缘导线遭雷击断线的机理,并结合鄂尔多斯市东胜区配电线路的具体情况、配电线路可靠性的要求、雷电活动的特点及经济能力,综合比较国内外常用的几种10 kV架空绝缘导线雷击断线防护技术措施的特点,提出了采用穿刺型防弧金具防护雷击断线这一技术手段是比较经济、有效的,可以满足当地供电可靠性的要求。The insulation and corrosion resistance of overhead insulated conductor is better than that of regular overhead bare wire.As compared with the underground cables in the investment,construction and maintenance,overhead insulated conductor have clear advantages,so there are increasing applications of the conductor during the process of the modernization of China＇s urban power grid.However,with the improvement of overhead line insulation degree of the city,the lightning-induced breakage problems become serious.In allusion to the problems,this paper discusses the lightning-induced breakage mechanism of 10kV overhead insulated conductors.On the basis of analyzing the specific circumstances and requirements of distribution lines,the characteristics of lightning activity and economic capabilities of Dongsheng District,Eerduosi City,foreign and Chinese techniques of preventing overhead insulated conductors from breaking are compared,and the use of stab-type arc-protection fitting for the said purpose is presented.This technological tool is more economical,efficient and reliable electricity supply to meet the local sexual demands.
