    摘 要:開關(guān)設(shè)備斷口的聯(lián)合電壓試驗是其重點絕緣型式試驗項目。在進行沖擊+工頻聯(lián)合電壓試驗中,由于兩個高壓電源回路間存在電容耦合,試驗時沖擊電壓會引起工頻側(cè)電壓跌落,需要采取適當(dāng)?shù)牡溲a償措施。討論了聯(lián)合電壓試驗中反向工頻電壓峰值系數(shù)的取值問題。以某1 100 kV GIS型隔離開關(guān)的雷電沖擊聯(lián)合電壓試驗(LIWV+AC)為例,通過實際試驗結(jié)合等效電路計算分析和ATP-EMTP仿真,重點研究了試品斷口電容、附加電容等參數(shù)對工頻側(cè)電壓跌落的影響,給出了合理的試驗方法,并對實際試驗中應(yīng)當(dāng)注意的問題進行了總結(jié)。

    Abstract: The combined voltage test is one of the most important dielectric type tests of switchgear breaker.During the impulse plus power frequency combined voltage test, due to the capacitance coupling between the two high-voltage power supply circuits, the impulse voltage will cause a voltage drop at power frequency side during the test, and appropriate voltage drop compensation measures should be taken. This paper briefly discusses the value of peak coefficient of reverse power frequency voltage in combined voltage test.Taking the lightning impulse combined voltage test (LIWV+AC) of a 1 100 kV GIS type disconnector as an example, through the actual test combined with the equivalent circuit calculation and ATP-EMTP simulation, the influence of capacitance across the open switching device and the additional capacitance on power transformer side voltage drop is mainly studied, and the reasonable test method is given.Finally, the problems that should be noted in the actual test are summarized.
    Key words: across the open switching device; voltage dorp; capacitance coupling; combined voltage test
