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.
