摘　　要：阐述配电网架空绝缘导线雷击断线机理和理论计算方法,将防止雷击断线的措施分为堵塞式和疏导式两大类,通过分析现有各种防雷产品的结构、特点、优缺点以及适用范围,对各种防雷措施进行比较,指出应结合实际情况选择合适的防范措施,最后总结配电网架空绝缘线路防雷击断线措施的研究趋势。This paper expounds breakage mechanism of overhead insulated wires of distribution networks and theoretical cal- culation method. Countermeasures against line breakage due to lightning protection are divided into dredging method and the blocking up method. By analyzing structure, characteristics, advantages and disadvantages as well as application scope of all lightning products at present, the paper compares all lightning protection measures and indicates that appropriate counter- measures should be adopted in accordance with practical situation. In the end, research trend of countermeasures against line breakage of insulated wires of distribution networks due to lightning strike is summarized.
