短路电流下间隔棒受力仿真研究

Research on the Stress of Spacer Rod under Short Circuit Current

间隔棒的应用越来越广泛,其受到损伤时将极大影响输电线路的安全运行。因此本文利用有限元仿真软件对某双框板间隔棒在线路发生短路时所承受的向心力进行了仿真研究,明确了间隔棒各部件在线路发生短路故障时的受力状况及薄弱点。结果表明:在这种工况下,间隔棒线夹端部、框架中部位移变化最大;间隔棒线夹本体与框架连接的根部、框架中部出现最大应力。

The application of spacer rods is more and more widespread,and when they are damaged,it will greatly affect the safe operation of transmission lines.Therefore,in this paper,the finite element simulation software was used to simulate the centripetal force that a double-frame spacer rod was subjected when a short circuit occurs.The results show that under this condition,the displacement of the end of the spacer clamp and the middle of the frame changes the most,and the maximum stress appears at the root of the connection between the spacer clamp and the frame and the middle of the frame.
