【摘要】 本文详细分析了100t高阻抗电弧炉短网系统各部分的电阻和电抗,发现电极电阻为短网系统电阻的主要组成部分,中相和边相电极电阻分别占各相总电阻的52.72%和54.32%;导电横臂、水冷电缆、导电铜管的电抗为短网系统电抗的主要组成部分,中相和边相的三部分电抗分别占各相总电抗的82.49%和82.24%。电弧炉的三相阻抗不平衡度为1.50%,满足设计要求。本文的计算结果和某厂100t高阻抗电弧炉的实际测量结果吻合,表明该计算方法在工程中应用是可行的,为炼钢电弧炉短网系统的优化设计提供了参考。更多还原

【Abstract】 Resistance and reactance of large current system in 100 t high-impedance EAF were analysed in this paper, which found that the electrode was the main part of system resistance, and electrode resistance in medium phase and lateral phase were respectively 52.72% and 54.32% of the total resistance. The reactance of current conducting arm, water-cooled cable, conductive copper tube were major components of large current system, and their reactance in medium phase and lateral phase were respectively 82.49% and 82.24% of the total reactance. The three-phase unbalance degree of impedance was 1.50%, which meets the design requirement. The calculation results agreed well with actual measured results in 100 t high-impedance EAF. The calculation method is feasible in engineering application, in favor of optimization design of large current system.更多还原
