Abstract


With the increase in the capacity of a single power transformer , the leakage magnetic field caused by the stray loss in the fuel tank and structural parts is significantly increased. The complexity of the structure of the transformer and irregularities lead to stray losses in each component distribution is very uneven , this uneven distribution can lead to local overheating transformer tank , clamps , which directly affect the operation of the transformer reliable sex . The study found that the the box eddy current loss is the main source of stray loss . Therefore, in-depth study the transformer leakage magnetic field and the box eddy current loss of engineering importance . Research in the subject belongs to the quasi-stable alternating electromagnetic field , Therefore, this paper first introduces the quasi-stable alternating electromagnetic field theory and finite element method analysis of the electromagnetic field used by the transformer leakage magnetic field generation mechanism of a certain degree the analysis . After the transformer reasonable simplification , the use of ANSYS electromagnetic finite element simulation software , established a two-dimensional simulation model is used to calculate the transformer tank leakage magnetic field of a model SFSZ11-1800000/220 power transformers , analysis of leakage flux the walls of the box and the winding distribution . On the basis of two-dimensional analysis of the leakage magnetic field , the magnetic shielding model of three-dimensional box eddy current loss model and the walls of the box . After simulation calculation shows that , in the walls of the box to take the magnetic shielding effect of eddy current losses , reducing the walls of the box is very significant. Compared through simulation and real data prove that the results of this study have a high practical value of future industry engineering and related technical personnel have certain practical significance and guiding significance .
