Optimization of electric transmission line of power grid with carbon fiber composite core conductor.

摘要

With the rapid development of the society, electricity has become a vital part of people's life.However, due to the limitation of some natural conditions, a series of power accidents oftenoccur. Therefore, optimization and improvement of power transmission lines has become animportant research topic. In this study, electric transmission line was optimized by using carbonfiber composite core conductor, and a mathematical model of composite temperature field ofcarbon fiber conductor under heavy load environment was established. Compared to thetraditional steel core aluminium conductor, the carbon fiber composite core conductor had lowersurface temperature and better heat resistance and current carrying capacity. Moreover theexperiment of resistance to corrosion was carried out on the two kinds of conductor, and it wasfound that the corrosion rate of the carbon fiber composite core conductor was lower than thatof the steel core aluminium conductor under acid rain solution with 3.0 PH value. Inconclusion, the corrosion resistance and thermal properties of the carbon fiber composite coreconductor are good. This study provides a new mode for the optimization and improvement ofelectric transmission lines.
