摘　　要：目前,输电线路受到外力破坏的影响仍比较严重。输电线路往往具有距离远、暴露时间长等特点,很容易受到外力的破坏。在外力破坏下,输电线路极易出现掉闸事故,从而导致输电线路的运行受到影响,进而对电网供电的稳定性产生影响。选取了国家电网有限公司某变电站的220 kV回线路为案例,对其近几年遭受的外力进行了分析,并提出有效的防治措施。希望研究结果不仅能为其他电站带来更好的安全防护,还能为其他类似电路提供参考。At present,the transmission lines are still seriously affected by external force damages.Transmission lines often have the characteristics of long distance and long exposure time,which are easy to be damaged by external forces.Under the damage of external forces,the transmission lines are prone to tripping accidents,which affects the operation of the transmission lines,and then affects the stability of the power supply of the power grid.The article selects the 220 kV return line of a substation of State Grid Co.,Ltd.as a case,analyzes the external force suffered in recent years,and puts forward effective prevention measures.It is hoped that the results will not only provide better safety protection for other power stations,but also provide a reference for other similar circuits.
