Abstract :
In order to analyze the change law between the maximum electric filed intensity of power transformer the electric filed distribution of 110kV power transformer is simulated using FEM software in the thesis, analyzes the main influence factor of the electric filed intensity of power transformer, the variation of maximum electric filed during different factor changing is determined, obtained the capacity of different factors influence on the maximum electric field intensity, proposed reducing the maximum electric field intensity and method of production costs, the theory has been determined for reducing the maximum electric filed intensity and the manufacturing cost of power transformer.
