| Abstract: | in the power transmission equipment,insulator is an important outer insulator part.It is used in electric insulator and machine fixedness.Composite insulator owns some advantages,such as: lighter weight,easy maintenance,etc.It is widely used in high voltage power transmission.In order to understand the insulator characters,this paper uses finite element method to analysis its electric field distribution,based on acquaint the insulator structure characteristic of 220kV composite insulator.First mathematics model of composite insulator is constituted.Then the ANSYS soft is used to calculate it.In the end,some calculated results are analyzed.Some conclusions are got.In this kind of insulator,the most uneven electric strengthen lies in two sharp ends of insulator,as same as it is easiest to appear part-discharge.This conclusion has practical instructional meaning to the usage of this insulator.The analysis method using in this paper can be widely applied in more complicated condition of various insulator’s electric field analysis. |
