摘　　要：针对江苏省内多种塔型多种挂点结构,研制出一种带电更换500kV直线转角塔绝缘子通用工具,并对其力学特性进行了分析。再利用有限单元法建立工具的精确受力模型,计算了其各部件的应力分布,计算结果表明整套承力工具能够满足机械强度的要求。This paper introduces a kind of general tool for live work insulator replacement for 500 kV suspension angle tower considering the character of multiple hanging points of towers in Jiangsu province. Also, the analysis on the mechanical property of this general tool is provided. Then using the finite element method the precise force model of the general tool is build, and the stress distribution of its each part is investigated. Calculation results show that the general tool meets mechanical strength requirement.
