Abstract:
As the cooling medium of transformer, natural ester insulating oil has better advantages than traditional mineral insulating oil. This paper compares the advantages and disadvantages of two kinds of insulating oil media from the electrical characteristics and non-electrical characteristics respectively. Natural ester insulating oil transformer has a large investment but long service life; Mineral insulating oil has less investment, but its service life is shorter than that of insulating oil transformer. Therefore, the economic comparative analysis of transformers made of two different insulating oil media from the manufacturing and operation stages is studied, which shows that natural ester insulating oil has good application value in transformer manufacturing.
