Research Direction of Oil-immersed Transformer

Abstract

With the continuous development of the electric power industry in the world, the application of oil-immersed transformer in all walks of life has become more and more extensive. But the safety problem of oil-immersed transformer, environmental protection problem, heat energy recovery and utilization problem are always the three mountains in front of the power system researchers. Therefore, it is particularly important to develop a new type of transformer that can adapt to the green, innovative and sustainable development of the power system. This paper will discuss the new ideas and new directions of oil-immersed transformer research in the future from three aspects: the study of transformer oil, the recovery and utilization of transformer heat energy, and the noise reduction of transformer.
