    摘 要:盆式絕緣子的可靠性對整套氣體絕緣金屬封閉開關(guān)設(shè)備 (GIS) 以及電網(wǎng)的安全運行至關(guān)重要。以 800 kV GIS 用盆式絕緣子為例,從盆式絕緣子的外形、屏蔽環(huán)、中心嵌件等方面綜合考慮進(jìn)行結(jié)構(gòu)設(shè)計,應(yīng)用有限元分析軟件對關(guān)鍵部位的絕緣性能和機(jī)械性能進(jìn)行仿真計算,計算結(jié)果滿足判據(jù)要求,并通過型式試驗驗證了設(shè)計的可行性。
    關(guān)鍵詞: 氣體絕緣金屬封閉開關(guān)設(shè)備;盆式絕緣子;結(jié)構(gòu)設(shè)計;絕緣性能;機(jī)械性能

    Abstract: The reliability of basin insulator is critical to the safe operation of complete Gas-Iinsulated Metal-Enclosed Switchgear(GIS) as well as the power grid. In this paper, taking the basin insulator used in 800 kV GIS as an example, the structural design of the basin insulator was comprehensively considered from the aspects of shape, shielding ring and center inset, etc, the insulation and mechanical properties of key parts were simulated calculated by finite element analysis software, the calculation results meet the criterion requirements, also the feasibility of the design was verified by type test.
    Key words: gas-insulated metal-enclosed switchgear; basin insulator; mechanical design; insulation property; mechanical property
