大型进口特种龙门铣床的电气系统改造

Transformation of large imported plano milling machine's electrical system

通过对进口大型特种龙门铣床电气系统的成功升级改造,阐述了改造过程中如何确定改造方案,如何选择国产电器元件以及通电试车中问题的分析解决,为其他大型机床的电气改造提供了较好的借鉴和参考。

Through successfully upgrading imported large special plano milling machine electrical system,expatiates how to determine the reconstruction scheme of the transformation process,how to choose domestic electric elements and gives solutions about electric test problem analysis,which provides a good reference for other large- scale machine tool electrical transformation.
