Discussion On The Aging Mechanism Of Pre-insulated Bushing Under Daily Working Conditions

Specifically for different experimental conditions, the views held by domestic and foreign researchers are as follows:
The research team represented by a professor at the University of Arizona in the United States used a single-needle-one-plate electrode to generate corona. By observing the surface state, weight loss, FTIR spectrum, etc. of the synthetic insulator after different corona times, the electrical aging mechanism of pre insulated sleeve in a humid environment was studied. The results verified the hypothesis that chemical reactions are the dominant factor in the corona aging of silicone rubber materials.
The professor and others simulated the end corona discharge of pre insulated junction sleeve and the sheath water droplet corona discharge, and conducted experimental research on the aging of insulated joint sleeve under these two corona discharge forms. .
