The Temperature Distribution Analysis and Temperature Rise Test of Pole Mold Transformer

초고압 현수애자의 Pin 형상에 따른 응력해석

Various types suspension insulators made of toughness glass or porcelain are used in the power transmission. And, Insulators are continually subject to mechanical and electrical stresses which depend on the characteristics of the line. The main factor that influence the increase in reliability of insulators. In operation is the capacity of the design to withstand the certain load over a long time, the mechanical strength of the insulators. This paper describes the results of a study on the stress analysis of suspension insulator based on the finite element analysis using NASTRAN. And, the mechanical strength was evaluated through such as kinds of pin type.
