Research on the Remaining Life of Insulators in High Speed Train under Simulated Operating Environment
This paper presents a method for analyzing the service life and residual life of high temperature vulcanized silicone rubber for composite insulators under comprehensive aging.By analyzing the degeneration trend of tensile strength and the initial tensile strength of the five-stage repaired silicone rubber,the service life of the new insulator silicone rubber and the remaining life of the five-stage repaired silicone rubber were evaluated.The experiment proved that,under the condition of comprehensive aging,the acceleration factor of new silicone rubber degenerative to the fifth grade repair is 18.64;It is further evaluated that the service life of the new umbrella skirt is 14.8 years,and the remaining life of the fifth class insulator repair umbrella skirt is 6.8 years.The follow-up can provide data support for insulator maintenance strategy optimization.
