The transformer is a device based on the principle of electromagnetic induction,realizing conversion of voltage and current,isolation and voltage stabilization,which is an important component in power conversion.In order to deal with the deformation and bending of transformer iron core steel sheet in production and transportation,an automatic straightening machine is proposed,realizing the automatic straightening of steel sheet and effectively improving the operation of transformer.In order to solve the heat dissipation problem of transformer,an automatic welding device of heat sink is proposed to realize the automatic installation and welding of heat sink,and can automatically detect and classify through ultrasonic flaw detection after welding,which greatly improves the production efficiency.On this basis,a transformer applied to power electronic conversion is designed,and the production and installation are completed.The correctness of the transformer parameter design and the proposed automatic steel sheet straightener and heat sink welding device are verified by experiments.
