Simulation of Dry-type Transformer Drying and DC Heating Temperature Field
In order to analyze the internal temperature of the DC heating device of the dry-type transformer,the corresponding three-dimensional model is built according to the actual DC heating device of the dry-type transform-er,and the temperature field simulation calculation of the device is carried out based on the multiphysics finite ele-ment software COMSOL Multiphysics,and the corresponding temperature field distribution cloud and the hottest temperature change when different currents are applied under different ambient temperatures and wire types are cal-culated The results show that the hottest temperature of the DC heating device will increase with the increase of the applied current and the ambient temperature,and the wire type has a certain influence on the temperature field dis-tribution of the device,which provides a certain reference value for the design and heat dissipation of the DC heating device of dry-type transformer.
