Abstract

The service life of the transformer is determined by its solid insulation performance. However, it is a rather difficult job to quantitatively evaluate the aging conditions of cellulose insulation materials of the transformer by traditional methods. The existing researches show that the cellulose aging kinetics model of cellulose can establish the functional relationship between the degree of polymerization (DP) and moisture content, aging temperature and aging duration. Therefore, based on the simultaneous considering Arrhenius equation and Ekenstam equation, the purpose of this work is to report an approach that can quantitatively evaluate the aging condition of cellulose insulation of transformer. Furthermore, the present finding of this paper can provide a novel idea for evaluating the aging state of transformer solid insulation.
