【摘要】我公司220KV天靖Ⅱ线于1998年10月投运,由于该线路的直线杆塔全部采用合成绝缘子,这在我公司尚属首次,合成绝缘子也因此为我公司从事输电线路的各类人员所熟识。通过对合成绝缘子工业的发展及其自身特点的了解,我们加深了对合成绝缘子的认识并基本掌握了它的各种特性,为了使它能更好地运行在线路上,提高线路的绝缘水平和供电可靠性,以服务于靖江地方经济的发展,通过近四年的线路运行管理工作,我们总结出了一些运行经验,明确了合成绝缘子运行维护的工作重点,同时还讨论了有关合成绝缘子的检测和评定方法。在确保现有线路合成绝缘子正常运行的同时,也为今后其他线路合成绝缘子的运行提供宝贵的经验。目前该线路的402支合成绝缘子运行状况良好。
Abstract 220kV Tianjing line Ⅱ of our company was used on October,1998. It’s unprecedented that all the straight poles and towers of this line have adopted composite insulators. Accordingly,composite insulators are familiar to all the persons who are engaged in power-transitting lines. We have further knew and basically mastered all their own characteristics since we got to know the development of composite insulator industry and all its characters. To make them run on the lines better and improve the insulated levels of the lines and credibility of power-supplying, thus serving the Jingjiang regional economical development, we have concluded and well-defined some experiences and stresses of service and maintenance over 4 years’ line management. And we have also talked about some ways which can be used to test and eva luate composite insulators. We do so to not only ensure composite insulators of recent lines to run normally, but also provide treasured experiences for those of all the other lines afterwards. At present 402 composite insulators of this line have been running well.
