摘　　要：随着电弧炉技术发展,对于电弧炉短网阻抗计算的精度有了更高的要求。电弧炉短网结构多样,传统的电抗解析计算方法的准确度无法满足日益提高的短网设计要求,本文采用有限元法进行短网电抗计算,对短网复杂结构建模并进行电磁场分析,提高短网计算的准确度。As the development of EAF technology,there is higher accuracy requirement for EAF lead impedance computation.Considering that EAF lead has diverse structures,it is crucial to analyze the electromagnetic field precisely based on the structure of lead.In order to meet the requirement of the EAF engineering design,this paper calculates the lead impedance in FEM,analyses the electromagnetic field of the complex lead structure,thus,improves the accuracy of the calculation.
