【摘要】我公司220KV天靖Ⅱ線于1998年10月投運,由于該線路的直線桿塔全部采用合成絕緣子,這在我公司尚屬首次,合成絕緣子也因此為我公司從事輸電線路的各類人員所熟識。通過對合成絕緣子工業(yè)的發(fā)展及其自身特點的了解,我們加深了對合成絕緣子的認(rèn)識并基本掌握了它的各種特性,為了使它能更好地運行在線路上,提高線路的絕緣水平和供電可靠性,以服務(wù)于靖江地方經(jīng)濟(jì)的發(fā)展,通過近四年的線路運行管理工作,我們總結(jié)出了一些運行經(jīng)驗,明確了合成絕緣子運行維護(hù)的工作重點,同時還討論了有關(guān)合成絕緣子的檢測和評定方法。在確保現(xiàn)有線路合成絕緣子正常運行的同時,也為今后其他線路合成絕緣子的運行提供寶貴的經(jīng)驗。目前該線路的402支合成絕緣子運行狀況良好。
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.
