摘　　要：伴随着我国电力系统的蓬勃发展,电网系统也在不断发展和完善。电能在社会的发展与建设中起着非常重要的作用。随之在发展中出现的问题也慢慢浮出水面,可以看到电网在带来便利的同时也出现了其他问题,尤其是电力配送网络中出现的线路故障问题。近年来,城乡10 kV配电线路因为雷击问题而出现跳闸故障的事件屡见不鲜,雷击问题已成为造成10 kV配电线路出现故障的重要原因之一。该问题出现的频率越来越高,不仅影响整个电力系统的正常运行,而且给人民群众的生命和财产带来巨大的安全隐患,据此探讨解决10 kV配网线路防雷技术措施对人们的生活和工作有着必要联系。在此主要分析雷击10 kV配网线路的防雷难点问题,同时提出相对的措施,希望能够在一定意义上有效降低10 kV配电线路的故障率,为保障人们生产和生活的正常运行提供参考性意见。With the vigorous development of my country’s power system,the power grid system is also constantly developing and improving.Electricity plays a very important role in the development and construction of society.Following the development,the problems gradually surfaced.It can be seen that while the power grid has brought convenience,other problems have also appeared,especially the problem of line failures in the power distribution network.In recent years,it is not uncommon for 10 kV distribution lines in urban and rural areas to trip due to lightning strikes.To a certain extent,lightning strikes have been one of the important reasons for the failure of 10 kV distribution lines.It is worth noting that the frequency of this problem is also getting higher and higher.The emergence of this problem not only affects the normal operation of the entire power system,but also brings huge safety hazards to the lives and properties of the people,so we will discuss and solve them accordingly.The proposition of 10 kV distribution network line lightning protection technical measures has a necessary connection to our life and work.This article mainly analyzes the reasons for the difficult problems of lightning protection of 10 kV distribution network lines from lightning,and proposes relative measures for the lightning protection problems of 10 kV distribution network.It is hoped that the failure rate of 10 kV distribution lines can be effectively reduced in a certain sense,and it can provide reference opinions for ensuring the normal operation of people's production and life.
