摘要本文提出了一种三相三柱式变压器铁心夹件结构,通过采用有限元（FEM）分析软件ANSOFT对该种结构进行3D漏磁场建模分析,对比其他两种常规夹件结构,对变压器漏磁场及结构件热点温升进行仿真研究,通过对比分析,得出该种结构可以有效避免三相三柱变压器铁心外侧漏磁通引起的结构件过热的问题,也有效降低了三相三柱式铁心变压器的结构耗,为大型三相三柱式变压器的安全可靠运行提供了强有力的保障和支持。

Abstract：This paper presents one type structure for three-phase three-limbs transformer core clamping plate by using finite element analysis software ANSOFT (FEM) on the structure analysis of leakage magnetic field model of 3D, compared with the other two conventional clamping structure,made simulation research from transformer leakage magnetic field and the structure of hot spot temperature rise, through comparative analysis, draw this kind of structure which can effectively avoid three-phase three-limbs transformer core outer leakage flux caused structural overheating, but also effectively reduces the structure loss of three-phase three-limbs transformer,and provide a strong guarantee and support for large three-phase three-limbs transformer safe and reliable operation.

Key words： three-phase three-limbs transformer FEM structure of clamping plate leakage magnetic field hot spot temperature rise structure loss
