A study on the v-t characteristics of interfaces between Toughened Epoxy and Rubber with Inverse Power Law

역승법칙을 이용한 터픈드 Epoxy/Rubber 계면의 V-t 특성에 관한 연구

In this study, the interfacial dielectric breakdown phenomenon of interface between Epoxy and Rubber was discussed, which affects the stability of insulation system of power delivery devices. The breakdown strength of specimens are observed by applying high AC voltage at the room temperature. The breakdown times under the constant voltage below the breakdown voltage were gained. As constant voltage is applied, the breakdown time is proportion to the breakdown strength. The life exponent n is gained by inverse power law and the long time breakdown life time can be evaluated.
