摘要
在全球气候变化日益加剧的背景下,极端气候事件的频繁发生给220 kV以上架空输电线路稳定运行带来严重威胁。就强风、暴雨、暴雪及冰冻等极端天气对输电线路稳定运行的影响进行分析,并讨论相关的加固方法。加固措施主要有杆塔基础加固、导线的防舞和防风偏措施、绝缘子的防污和憎水改性。通过上述方法有效地提高了极端气候下输电线路的稳定性与可靠性,确保了电力系统安全平稳运行。
Against the backdrop of increasingly severe global climate change,the frequent occurrence of extreme weather events poses a serious threat to the stable operation of overhead transmission lines above 220 kV.This paper analyzes the influence of extreme weather such as strong wind,rainstorm,snowstorm and freezing on the stable operation of transmission lines,and discusses relevant reinforcement methods on this basis.The reinforcement measures mainly include tower foundation reinforcement,anti dancing and anti wind deviation measures for wires,and anti fouling and hydrophobic modification of insulators.The above methods can effectively improve the stability and reliability of transmission lines under extreme weather conditions,ensuring the safe and stable operation of the power system.
