Micro‐mechanism study on synergistic degradation of the oil‐paper insulation with dibenzyl disulfide, hexadecyl mercaptan and benzothiophene

Abstract: In recent years, there have been many cases of transformer failures caused by corrosive sulfides. At present, research mainly focuses on the single sulfide dibenzyl disulphide, but few research on multiple sulphur or the oil-paper hybrid insulation. In this study, three typical sulfides dibenzyl disulfide, hexadecyl mercaptan and benzothiophene were selected to form seven sulfide-oil-paper models. Then relaxation calculations were carried out, and through molecular dynamics simulation, the synergistic effect o… Show more

“…The study on their physical and chemical properties will contribute to the development of advanced corrosive resistant materials and the realization of corrosive state monitoring. Numerous efforts have been made to study properties of the DBDS, DBS, and BiBz, including chemical reactivity [7,8], synergistic effect [9,10], detection methods [6,11], etc. [12,13].…”
