摘 要:1 100 kV 氣體絕緣金屬封閉輸電線路(GIL) 設(shè)備為世界范圍內(nèi)較先應(yīng)用,目前尚無完善的現(xiàn)場交接試驗(yàn)方案,為解決這一現(xiàn)狀,對(duì)制約1 100 kV GIL 現(xiàn)場交接試驗(yàn)的項(xiàng)目進(jìn)行了分析研究。通過創(chuàng)新現(xiàn)場主電阻和氣體密度測量方法,將常規(guī)電阻測試中的正極或負(fù)極電流測試線用1 100 kV GIL 外殼代替,并設(shè)計(jì)專門的電阻測量結(jié)構(gòu),解決了現(xiàn)場測試線長度不足的難題;通過制作專門的硬質(zhì)檢漏工裝,解決了現(xiàn)場檢漏氣體定量不準(zhǔn)確的問題。該方案的實(shí)施,解決了困擾1 100 kV GIL 現(xiàn)場交接試驗(yàn)的困難。

    Abstract: The 1 100 kV GIL is the first application in the world. At present, there is no perfect on-site handover test scheme.In order to solve the problem, the project that restricts the 1 100 kV GIL field handover test was analyzed and researched.By innovating on-site main resistance and gas density measurement methods, replacing the positive or negative current test line in the conventional resistance test with a 1 100 kV GIL shell, and designing a special resistance measurement structure to solve the problem of insufficient field test line length.The problem of inaccurate gas quantification for on-site leak detection is solved though making special hard leak detection tooling.The implementation of this program solved the difficulties that plagued the 1 100 kV GIL field handover test.
    Key words: GIL; test scheme; field test; pipe corridor
