摘　　要：通过分析10kV架空绝缘导线雷击断线的机理,比较国内外架空绝缘导线雷击断线防护技术措施的特点,提出采用穿刺型防弧金具防护雷击断线这一技术手段。阐述了穿刺型防弧金具防止雷击断线的原理,并以广东电网公司中山供电局为应用实例,介绍了该局创新设计的穿刺型防弧金具的结构特点和性能,2年的运行情况表明,穿刺型防弧金具能解决架空绝缘导线雷击断线的问题。On the basis of analyzing the lightning-induced breakage mechanism of 10 kV overhead insulated conductors, 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 with corresponding mechanism expounded. Taking Zhongshan Power Supply Bureau of Guangdong Power Grid Corporation as an example, this paper describes the structural feature and performance of the stab-type arc-protection fitting newly designed by the bureau. The two-year operation result shows the favorable effect of stab-type arc-protection fitting in solving the problem.
