Study on the Thermal Analysis of Extra-High Voltage OF Cable Accessories using Finite Element Method

유한요소법에 의한 초고압 OF 케이블 접속재의 주도해석에 관한 연구

This paper presents the thermal analysis of EHV OF cable accessories using FEM. The governing equation about the temperature in the cable accessories is induced by the energy balance equation. Since the temperature distribution is a function of space and time, the weighted residual method is adopted for FEM formulation. The difference approximation is used to treat the time differential term in the element equation. Automatic mesh generation which save time and labor is introduced for the data input process. It will be expected that the following thermal analysis result will be very useful to cable accessories design.
