Abstract
This paper focuses on the study of the multi-stress coupled insulation failure mechanism of ±1100kV oil-impregnated paper capacitive wall bushings. By analyzing the combined effects of electrical, thermal, and mechanical stresses, the failure characteristics and development patterns of the insulation materials under complex operating conditions are revealed. The research results provide a theoretical basis for improving the insulation reliability and optimizing the design of bushings, contributing to the safe and stable operation of high-voltage power transmission equipment.
Key words： ±1100kV; Oil-impregnated paper; Wall bushing; Multi-stress coupling; Insulation failure mechanism
