摘　　要：随着用电需求的增大,电网工程的建设规模也逐渐扩大,架空输电线路更是呈现出大跨度的建设特点。输电线路作为电力系统的重要组成部分,一旦暴发安全隐患便会直接影响供电质量与供电安全,因此,相关人员对架空输电线路工作给予了较大的关注。雷击因素是输电线路运行中不可避免的影响因素,很大程度上威胁了供电安全。从应用和发展的层面来看,雷击问题已经成为限制电力事业健康发展的关键性问题之一。因此,对架空输电线路防雷与接地的设计要点进行梳理,以期提高输电线路的防雷接地水平,并以具体的输电线路工程为例,系统研究防雷接地设计方法。With the increasing demand for electricity,the construction scale of power grid projects is gradually increasing,and overhead transmission lines are showing the characteristics of large-span construction.As an important component of the power system,transmission lines can directly affect the quality and safety of power supply in case of safety hazards.Therefore,relevant personnel have paid great attention to the work of overhead transmission lines.At present,lightning strikes are an inevitable factor affecting the operation of transmission lines,posing a significant threat to power supply safety.From the perspective of application and development,lightning strikes have become one of the key issues limiting the healthy development of the power industry.Therefore,the following article summarizes the design points of lightning protection and grounding for overhead transmission lines,in order to improve the lightning protection and grounding level of transmission lines,and takes specific transmission line projects as examples to systematically study lightning protection and grounding design methods.
