摘要
本文简要介绍了大型铸造起重机工艺特点以及变频器在大型铸造起重机中应用的特殊环境,结合国际几家主要的IGBT供应商以及文献[3]对于IGBT电压电流的选择,分析了某大型钢厂铸造起重机380t在用变频系统大容量IGBT的电压电流选择存在的问题。
This paper introduces the technique of large Ladle crane and the special environment of inverter's using.Joining international main supplier and the literature[3]about the choice of IGBT's voltage and current,it introduces the question being in option of high power IGBT which using in frequency converter of 380t Ladle crane in large steel found.
