| 2 | Reviews on sulphur corrosion phenomenon of the oil-paper insulating system in mineral oil transformer显示文摘The active sulphur compounds in transformer oil would react with copper wires and produce cuprous sulphides,which then attach themselves to the surface of copper wires and insulating paper,thus reducing the electrical performance of oil-paper insulation and causing insulation failure.This article aims to make a comprehensive summary on the field of sulphur corrosion of oil-paper insulation in the mineral oil transformer,including the corrosion mechanism of sulphide on copper sheets,the deterioration mechanism of sul-phide on oil-paper,the factors influencing sulphur corrosion reaction,the method of characterising the degree of sulphur corrosion,the protection technology of sulphur corrosion and the field operation measures for sulphur corrosion.Moreover,four key problems that need to be further solved were sorted out:the synergistic deterioration mechanism of sulphide and its transformation mechanism,the micro-process and forming path of sulphur corrosion reaction,the characteristic parameters and quantitative charac-terisation methods of sulphur corrosion degree,and the effective protection technology of sulphide corrosion.To solve these problems,efforts will be made for deeper understanding of the sulphur corrosion phenomenon and its deterioration mechanism based on theo-retical background,the assessment methods and protection technology,endeavouring to put forward solid theoretical basis and feasible technical means for preventing sulphur corrosion insulation failure. | Haoxi Cong Hao Pan Danyang Qian Haiyu Zhao Qingmin Li | 2021 | High Voltage2021，6，2： | 1 |
| 3 | Micro‐mechanism study on synergistic degradation of the oil‐paper insulation with dibenzyl disulfide,hexadecyl mercaptan and benzothiophene显示文摘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 of different sulfides on the properties of insulating paper and insulating oil was discussed.Results show that the coexistence of the three sulfides has the most severe weakening on the mechanical properties of cellulose,and it also causes great damage to hydrogen bonds.Hexadecyl mercaptan has a weaker effect on hydrogen bond destruction,but it will greatly aggravate the cellulose chain movement.The viscosity of insulating oil is generally increased by the influence of sulfide.Hexadecyl mercaptan is the main factor affecting the viscosity.Thiophene has little effect on the viscosity,ctive protection technology on sulphur corrosion. | Haoxi Cong Hao Pan Xuefeng Hu Minhao Zhang Qingmin Li | 2021 | High Voltage2021，6，3： | 0 |
