特高压GIS断路器用管型绝缘拉杆动态受力真型试验与材料压缩特性分析
Gaoya dianqi作为特高压GIS断路器中连接触头与操作机构的关键部件，绝缘拉杆在操作过程中需要承受外载荷作用。为掌握绝缘拉杆动态受力特性、材料力学性能，文中通过在特高压GIS断路器中布置力传感器测得其主绝缘拉杆操作过程中动态受力情况，根据测试结果进行了拉杆材料管型试样的压缩试验，并利用仿真分析了不同长径比拉杆的压缩屈曲特性。试验结果表明，操作过程中主绝缘拉杆受交变冲击载荷作用，操作机构对绝缘拉杆所施加压力峰值与拉力峰值相差不大，且二者均达到110 kN以上，绝缘拉杆材料的压缩特性应得到关注。压缩试验结果表明长度和内 ...
