摘　　要：随着10 kV配电线路绝缘化改造的推进,线路雷击断线率不断增加。传统的配电线路防雷保护装置主要分为“疏导式”和“阻塞式”,近年来也出现了气体灭弧式防雷装置在架空线上的广泛应用,在线路防雷保护上都取得了不错的效果。本文分析了绝缘导线雷击断线的原因,阐述了防雷保护装置的发展历程,总结不同类别防雷装置的保护原理及特点,探讨了10 kV架空线路防雷保护装置未来研究发展方向:抗老化性、串联外空气间隙、多灭弧室、瞬时高速气流和高使用寿命。With the advancement of insulation transformation of 10 kV distribution lines,the rate of lightning-caused breakage for distribution lines is increasing.The traditional lightning protection devices for distribution lines are mainly divided into dredging type and blocking type.In recent years,gas arc-extinguishing lightning protection devices have also been widely used in overhead lines,and have achieved good results in lightning protection for 10 kV overhead line.This paper analyzes the causes of lightningcaused breakage for distribution lines,expounds the development history of lightning protection devices,summarizes the protection principles and characteristics of different types of lightning protection devices,and discusses the future research and development direction of lightning protection devices for 10 kV overhead lines:aging resistance,series external air gap,multiple arcextinguishing chambers,instantaneous high-speed airflow,long service life.
