摘要
某220 kV输电线路导线在运行过程中发生了断裂故障,严重影响了电网运行的安全稳定性。文章通过对220 kV输电线路导线的外观检查、力学性能试验分析其抗拉强度和伸长率指标、X射线探伤检测,分析得出了本次导线断裂的原因。针对本次故障暴露出的问题,提出了防范思路和应对措施,为电网安全稳定运行提供保障。
A breakage fault occurred in the conductor of a 220 kV transmission line during operation,which seriously affected the safety and stability of the power grid.In this paper,the tensile strength and elongation rate indicators of the 220 kV transmission line conductor are analyzed through visual inspection and mechanical performance test,and X-ray flaw detection is conducted.Based on the above results,the cause of the wire breakage is identified.In response to the problems exposed by this fault,preventive ideas and countermeasures are proposed to ensure the safe and stable operation of the power grid.
