Speech Title: Vegetable oil transformer transition metal degradation mechanism and protection technology
Abstract: Vegetable oil   transformer has the advantages of strong overload capacity, green environment   protection, low loss, small local discharge, etc. It is an ideal green   transformer with wide application prospect in the future. Vegetable oil   transformers will gradually deteriorate under the action of electrical and   thermal stress during operation, and are also affected by many environmental   factors, and the degree of deterioration of their oil-paper insulation is   closely related to their operating life. Research shows that the transformer   core and winding of iron, copper and other transition metals have redox   activity, long-term operation process will accelerate the deterioration of   vegetable oil paper, a serious threat to the safe and stable operation of   vegetable oil transformers. The core and copper windings are immersed in   vegetable insulating oil for a long time, and high temperature and local   overheating may occur in transformer operation, coupled with the influence of   external factors such as electric field, oxygen, moisture, acid, etc.   Therefore, the deterioration reaction mechanism of iron, copper and other   transition metals on vegetable oil paper under the above circumstances will   be more complex. In order to break through the above bottlenecks, the organic   combination of macroscopic experimental research and microscopic molecular   simulation is used to reveal the process and mechanism of the degradation   reaction of coke transition metals on vegetable oil paper, and on this basis,   a quantitative characterization method for the severity of the degradation   reaction of transition metals on vegetable oil paper is established, and an   effective protection method for vegetable oil paper insulation in the presence   of transition metals is proposed. It has important scientific exploration   significance and broad engineering application prospect for ensuring the safe   and stable operation of future vegetable oil transformers, building strong   and green power grid, and strengthening environmental protection and   sustainable development.
