    摘 要:因氮氣物理化學性能穩(wěn)定,作為環(huán)保型氣體絕緣介質在氣體絕緣開關柜領域受到了重點關注。在目前氣體絕緣開關柜常用的非圓柱形電極下對純氮氣分別進行了工頻耐壓和雷電沖擊耐壓試驗,并對試驗結果進行多角度分析,通過曲線擬合得到了較低壓力下氮氣擊穿電壓(Ub)與氣壓和放電距離的乘積(p×d)關系經(jīng)驗公式,研究結果對氮氣絕緣開關設備研發(fā)具有一定的指導意義。

    Abstract: As an environmentally friendly gas, Nitrogen gas has received close attention recently in the field of gas insulated switchgear due to its stable physical and chemical properties. The power frequency voltage withstand test and lighting impulse voltage withstand test were conducted in lower pressure for the pure N2 gas in non-columniforn electrodes which was commonly used in gas insulated switchgear, and the test result underwent a multi-angled analysis.The curve-fitting method was used to obtain the experiential formula of the relationship between breakdown voltage Ub and p×d in lower pressure. The research result is significant in guiding the research and development of nitrogen
insulated switchgear.
    Key words: gas insulated switchgear; environmentally friendly gase; N2; insulation performance
