Summary:The Pad mounted Transformer is an important equipment for energy transfer in wind farm. Aiming at three cases of pad mounted transformer core heating faults occurring continuously in a wind farm, oil analysis and disintegration of the fault transformer are carried out, and the fault points causing the heating are found. In order to analyse the mechanism of the fault, the eddy current field analysis model is established by using finite element analysis software ANSYS MAXWELL to analyse the change. Quantitative calculation is carried out for the heating condition of the winding and core of the press. Through analysis, it is determined that there are defects in the manufacturing process of pad mounted transformer, and the reason of heating failure is that the low-voltage winding at the head contacts too closely with the iron core.
