摘要
雷电风险是在雷暴天气中出现的一种电力系统故障,可能对电力系统运行造成严重的损害。为了有效减少或消除雷电风险,必须对配电线路中布局材料等可能引发雷电事故的因素进行深入研究和分析。设计了一种高压配电线路防雷方法,采取两项措施来降低防雷的成本,并确保防雷功能实现。使用典型的配电配置以提高在省略中间相电弧角的高压输电线路情况下的防雷性能,拆除地线时,将支架与接地线一起留下可降低雷击风险。
Lightning risk is a type of power system failure that occurs during thunderstorm weather,which may cause serious damage to the operation of the power system.In order to effectively reduce or eliminate lightning risks,it is necessary to conduct in-depth research and analysis on factors such as layout materials in distribution lines that may cause lightning accidents.This article proposes a reasonable lightning protection design for high-voltage distribution lines to reduce capital investment costs and ensure lightning protection functions.Two measures are taken to reduce the capital investment costs of lightning protection.In this study,a typical distribution configuration is used to improve the lightning protection performance of high-voltage distribution lines that omit intermediate arc angles.When removing the ground wire,the support and ground wire are left together to reduce the risk of lightning strikes.
