Speech Title:Synergistic Deterioration Mechanism and Protection Technology of Multiple Sulfur Corrosion Phenomenon in Power Transformer

Abstract:Multiple active sulfides in the transformer oil could react with the copper conductor to form cuprous sulfide, which adheres to the surface of the copper wire and the insulating paper, reducing the oil-paper electrical properties and cause insulation failure. At present, most scholars mainly focused on the corrosiveness of the single sulfide DBDS, while few on other sulfides and their synergistic deterioration effects. Based on the macroscopic experiment and microscopic molecular simulation, the project intends to analyze the change rule of aging characteristic parameters under different sulfide, voltage and temperature, to clarify the reaction process and their mutual conversion of multiple sulfur corrosion. Also, the synergistic deterioration mechanism of the oil-paper insulation by different sulfurs would be revealed. By extracting the decoupling characteristic parameters which can quantitatively characterize the multiple sulfur corrosion degree, the mathematic correlation model of the sulfur compositions, the aging characteristic parameters and the sulfur corrosion severity can be established, also with the quantitative characterization method of the sulfur corrosion severity degree. The protection effectiveness of passivator under multiple sulfur corrosion would be studied and the optimal passivator concentration for different corrosive sulfurs will be proposed. This project has certain scientific significance and application value for further revealing the sulfur corrosion phenomenon and its synergistic degradation mechanism, as well providing theoretical basis and technical means for preventing the sulfur corrosion insulation fault.
