The physical model of dry type transformer was established by the professional mechanical designing program SOLIDWORKS, and the calculation of iron core and windings' temperature rises were based on heat conduction theory. The physical model that had been established in SOLIDWORKS was imported into COMSOL to conduct the simulation of temperature field analysis. In comparison with the experimental...
The operating conditions of dry-type transformers depend largely on the winding insulation properties, and the winding insulation properties is closely related to its internal temperature distribution. In order to more accurately obtain the transformer thermal field distribution characteristics, this paper used the method of theoretical deduction combining with multi-physics finite element analysis...
