A Study on the Estimation of ACSR's Life using Tensile Characteristics |
Abstract |
The considerations for reminder life of transmission line is gradually higher. It is requisite for investigation of ACSR"s life to test tensile load of ACSR as a fundamental data. It is vary important to analysis correlations between results of tensile load testing and elasped years. Estimation of ACSR"s life can be obtained by statistics processing using mechanical experimental results. It is a general method to use regression analysis as a statistics processing technique. In this paper, we did experiment on tensile strength of ACSR by using a new and old ACSR as sample experimental materials. The limit of life estimation is decided by basic line using twenty percentage reduction of rate tensile strength. This basic line is like to results of Canada Ontario Hydro-research. There are 95[㎟], 97[㎟], 120[㎟], 240[㎟] ACSRs which are experimented on this study. The life estimation of these ACSR is presented by table 1 to be obtained through the linear regression and nonlinear regression analysis. SPSS and statistics toolbox of matlab is used for analysis. |
