摘　　要：文章针对环氧浇注干式变压器发生突发短路故障后线圈、出线排等各部分短路力进行分析,结合短路试验的失败经验,找出变压器三相对称短路情况下易发生变形的位置,给出变压器这些薄弱点的加强措施,并提出变压器整体在抗短路能力方面的设计注意事项。This article analyzes the short-circuit force of each part of the coil and the outlet bar after the sudden short-circuit failure of the epoxy cast dry-type transformer,and combines the experience of the failure of the short-circuit test to find out the positions that are prone to deformation in the case of a three-phase symmetrical short-circuit of the transformer.The strengthening measures for these weak points of the transformer are given,and the design precautions for the overall short-circuit resistance capability of the transformer are put forward.
