비등온 TGA을 이용한 절연재료의 활성화에너지 신뢰도 향상

다국어 초록 (Multilingual Abstract)

Measuring the accurate activation energy of the insulating materials used in the HVDC environment is an essential condition for reliable prediction of the accelerated life of the insulating materials, so it is important to select various measurement models and analyze them. The activation energy of PE and PP was measured through five measurement methods through TGA, and the reliability was improved by comparing the results of each condition of the heating rate, the degree of conversion and the reaction order. Excluding the conditions that cause errors, the measured activation energy was measured to be 2% lower than the existing measurement methods, and it is thought that it will be used as a useful basic data in the field of reliability.
