Effect of Magnetic Shunts on the Eddy Losses of a Transformer Tank

Abstract:

This paper presents a 3D FEM computation model for a power transformer structure, where several conductor disks in series are used to constitute each winding, this is different from the normal cylindrical shape models. Base on such model the simulated ohmic losses in windings can be the same as that of measured. Then the stray magnetic fields in the transformer, the eddy losses in tank, the effect of magnetic shunts on tank losses are all studied, the calculated decrease of eddy losses in tank when magnetic shunts are properly used is compared with that of measured, they are coincide in some degree, which imply this model is reasonable for the simulation
