The high-voltage transformer panel receives high voltage from KEPCO, steps it down to distribution voltage, and then distributes the power to the low-voltage panel. Due to the recent increase in heating and cooling facilities due to abnormal temperatures and the increase in heat load due to the government’s carbon reduction policy, there has been a sharp increase in electricity demand, requiring measures to prevent overheating in the high-voltage transformer panel. In this study, a three-dimensional thermal–fluid analysis of the high-voltage transformer panel under actual operating conditions was performed using COMSOL Multiphysics, and the resulting simulations were used to derive heat transfer conditions that lower the transformer temperature by relying only on natural energy. These results indicate that, when applied to enclosed electrical equipment, the proposed passive cooling strategy can suppress temperature rise using only natural energy without any external cooling devices, thereby contributing to the construction of sustainable, circular-economy-oriented energy infrastructure by reducing energy consumption, minimizing resource use, and extending equipment lifespan.
