    Abstract:

    Sulfur corrosion is widespread in transformer oil.The generation of corrosive sulfide can affect the performance of insulation winding and cause equipment failure.In this paper,the influence of corrosive sulfide in transformer oil on the partial discharge characteristics of insulation winding is studied.Through partial discharge test of insulation winding samples with different corrosion conditions,the influence of the corrosive sulfide deposition on the partial discharge characteristics of winding is obtained.The results show that the deposition of corrosive sulfide reduces the initial discharge voltage of the insulation winding,which makes the insulation winding easy to discharge,and the discharge density and discharge repetition rate are proportional to the deposition of corrosive sulfide.
