Abstract:It is the most important thing to ensure the integrity and safety of transformer when shipped.A transformer winding and an equipment for pre-compression were simulated by using the nonlinear finite element method. The loss coefficient for this way of pre-compression was analyzed,and the variation of the safety factor of the block was presented.The relations between the changes of pre-compression and safety factor on the shipped transformer were investigated.The results show that the way and the effect of pre-compression on large transformer windings can be simulated distinctly by virtue of the life-death element technique,and the impact of transport can be reflected reasonably by dynamic analysis when the large transformer is shipped.
