Description
Summary:The ventilation system design of dry-type air-core reactor is a complex task that must determine the thermal loads to achieve the maximum insulation material exploitation. In this paper, the temperature rise in reactor is due to Joule's losses and heat dissipation by air convection, convection and radiation. The Joule's losses calculated by coupled magnetic field-circuit analysis are used as the input for the thermal field by finite-element analysis, which is directly coupled with fluid analysis. Finally, the temperature distributions of reactor can be calculated. Therefore, the thermal performance analysis of air-core reactor could be conducted in the early design stage to guarantee the insulation material requirements.
