摘　　要：LVQBT-500W2型SF6电流互感器运输过程中难度较大,易受到应力作用而损坏,为避免此种现象的发生,对包装用减震弹簧进行了一系列设计计算。通过COSMOSWorks的静态分析模块分析、数学、物理模型的建立、受力分析及电算程序求解等一系列复杂的过程,最终得到了包装用(全部)弹簧的刚度系数,并且验证此时盆式绝缘子最大变形量小于模型的约束条件,表明设计合理。LVQBT-500W2-type SF6 current transformer is difficult to transport,susceptible to stress caused damage.In order to avoid the occurrence of this phenomenon,a series of design and calculation for damping spring used in the packaging are carried out.Through using COSMOSWorks static analysis module,the mathematical and physical model are established,packaged with（all） spring stiffness coefficient has been obtained.It is verified that at this time basin-type insulator maximum deformation is less than the model constraints,reasonable design is confirmed.
