IGBT直接高压变频器在高炉水冲渣系统的应用

Application of IGBT high-voltage converter to the slag-washing-out pump

通过韶钢炼铁厂4 高炉冲渣系统采用IGBT直接高压变频器对水泵机组进行调速控制的实例,介绍国产IGBT直接高压变频器的性能,同时对其使用中出现的问题作了分析、提出解决方案.

In describing the application of the home-made IGBT converter to the pump speed control for the slag-washing-out system at No.4 BF of SISG, the paper illustrates the performance of the IGBT converter, analyses problems encountered in the application, and put forward resolutions to them.
