Simulation Research on the Partial Discharge Characteristics of Converter Transformer
2021 IEEE 4th International Electrical and Energy Conference (CIEEC)(2021)
Abstract
The converter transformer sustained the combined voltage of AC and DC at the same time, so the operation condition is quite complex. The oil paper insulation defects of converter transformer will directly affect the operation safety of converter transformer. In the course of long-term operation of converter transformer, the working temperature of converter transformer oil will change due to its internal insulation fault, load change, heat dissipation device fault and environmental temperature. Therefore, this paper analyzes the distribution of electric field and temperature when partial discharge occurs in the operation of converter transformer based on fluid dynamics theory and heat transfer theory. It is of great significance to ensure the normal operation of the transmission system
