    摘 要:以 40.5 kV 充氣柜雙氣箱結(jié)構(gòu)為例,以板材厚度和最薄弱的右側(cè)板為研究對(duì)象,在掌握結(jié)構(gòu)的設(shè)計(jì)、制造和生產(chǎn)工藝的基礎(chǔ)上,通過強(qiáng)度理論和有限元分析,得到雙氣箱結(jié)構(gòu)的計(jì)算和校核采用第一強(qiáng)度理論,以及應(yīng)力分布和變形量的分析云圖。理論分析確定了雙氣箱結(jié)構(gòu)宜選用 3 mm 不銹鋼材料,右側(cè)板經(jīng)過橫縱向加強(qiáng)布置后,比原結(jié)構(gòu)的變形量縮小了 70%,大幅度增加了氣箱結(jié)構(gòu)的強(qiáng)度,使其足以承受內(nèi)部燃弧中的高能量沖擊力。所采用的理論和輔助軟件分析方法,給 40.5 kV 充氣柜雙氣箱的實(shí)體設(shè)計(jì)提供了依據(jù)。
    關(guān)鍵詞:雙氣箱結(jié)構(gòu);內(nèi)部燃??;強(qiáng)度理論;應(yīng)力分析;變形量

    Abstract: This paper took a 40.5 kV inflatable cabinet with the double-tank box structure as an example and studied the thickness of the plate and the weakest right side plate. This study used the strength theory and the finite element analysis based on mastering the design,manufacturing, and production technology. The result showed that the first strength theory could be used in the calculation and verification process of the double-tank construction structure. This research obtained the cloud diagram of stress distribution and deformation. Theoretical analysis has determined that 3 mm stainless steel could be an appropriate material for making the double-tank box structure. After rearranging the right side plate horizontally and vertically, the deformation of the original structure shrank by 70%, which increased the strength of the air box structure to make it sufficient to withstand the internal arc. This paper provides a designed basis for the physical design of the double-tank air box of the 40.5 kV inflatable cabinet.
    Key words: double-tank construction; internal arc; strength theory; stress analysis; amount of deformation
