Performance Simulation of Natural Circulating Cooling System of SF₆ Gas Charged Transformer

SF₆ 가스를 충전한 변압기의 자연순환 냉각시스템의 성능시뮬레이션

Performance of naturally circulating cooling system of $SF_6$ gas charged transformer was simulated and the variations of gas flow rate, maximum coil temperature, gas temperature and cooling air temperature were investigated with respect to the height of radiator, interplates distance and heat generation rate at core. The results show that the height of radiator most significantly affects the performance of natural circulating cooling system of transformer.
