电力架空输电线路运维管理模式的分析与研究
摘要:长葛市电力架空输电线路,电压等级为:35kV、110kV、220kV,随着运行时间的增加,其线路通过各种不同复杂地形及一年四季不同气候条件,导线表层受空气中的氧化作用,环境温度的不同,其载流能力也有所不同;在各种环境条件、环境温度的实时性运行过程中线路故障性的缺陷,就会呈随机性出现;当这种缺陷性的故障刚开始出现时,对线路的安全运行及整个电网的安全运行,不会构成很大的威胁。但随着故障向贯穿性的延伸,就会造成线路故障性的停运。因此,以分析和研究电力架空输电线路各种运行故障的原因,并提出针对性运行维护措施,增强电网安全、稳定、可靠运行,具有十分重要的意义。

Abstract: Changge City overhead power transmission line, voltage rating: 35kV, 110kV, 220kV, with the running time increased, the line through a variety plex topography and different climatic conditions throughout the year, the wire surface oxidation in the air, the environment temperature, the current carrying capacity is also different in the defect; circuit real-time operation process of various environmental conditions ,the ambient temperature fault, there will be a random occurrence; when the failure of this defect appears first, safe operation for the safe operation of the lines and the entire power grid, will not pose a great threat. But with the fault to pierce through the extension of the out age, will cause the fault of. Therefore, in order to cause operation failure analysis and Research on power transmission line, and proposes safeguard measures, enhance the grid security, stability, reliable operation, has the very vital significance.
