    摘 要:以 40.5 kV 充气柜双气箱结构为例,以板材厚度和最薄弱的右侧板为研究对象,在掌握结构的设计、制造和生产工艺的基础上,通过强度理论和有限元分析,得到双气箱结构的计算和校核采用第一强度理论,以及应力分布和变形量的分析云图。理论分析确定了双气箱结构宜选用 3 mm 不锈钢材料,右侧板经过横纵向加强布置后,比原结构的变形量缩小了 70%,大幅度增加了气箱结构的强度,使其足以承受内部燃弧中的高能量冲击力。所采用的理论和辅助软件分析方法,给 40.5 kV 充气柜双气箱的实体设计提供了依据。

    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
