摘　　要：220 kV输电线路的安全稳定运行关系到人们正常生产生活秩序,因此需做好维护检修工作,快速判定故障点,从而采取合理的抢修技术。故障点定位效率主要取决于故障测距的精准度,需结合不同故障类型采取不同的测距技术。分析220 kV输电线路故障,采用阻抗测距分析技术和行波测距分析技术计算故障区段,在达到现场后快速确认故障点,提高故障点定位效率。The safe and stable operation of 220 kV transmission lines is related to the order of production and life,so it is necessary to do a good job of maintenance and repair,quickly determine the fault point,and thus adopt reasonable emergency repair technology.The efficiency of fault location mainly depends on the accuracy of fault location,and different location techniques should be adopted in combination with different fault types.The fault of 220 kV transmission line is analyzed,and the fault section is calculated by using impedance ranging analysis technology and traveling wave ranging analysis technology.After arriving at the site,the fault point is quickly confirmed and the efficiency of fault point location is improved.
