Simulation Analysis on Core Air Gap of Energy-Taking Current Transformer Based on Ansys
In view of the existing problems of energy-taking current transformer,such as large starting current,easy saturation of core,and inability to adapt to wider transmission line current,this paper designed and improved the core part.The core material was determined according to the initial permeability,saturation flux density,core loss and cost,and the core material was pretreated.Ansys software was used to design and simulate the shape of the core air gap.Through the magnetic leakage of the core in different shape of the air gap,the rectangular half opening was the best effect.The control variable method was used to simulate the size of the air gap,quantitatively analyze the size of the core air gap,and compare and analyze the saturation characteristics of the core and the output power of the sec-ondary side.This provides a good engineering value for the structural design and actual parameter selection of the core of the current transformer energy source.
