矿用通风机的变频改造

The inverter reconstyunction of mine ventilator

介绍了煤矿通风机在生产中的作用 ,对传统的运行方式进行了分析 ,着重介绍了矿用通风机变频改造的意义、效果 ,并结合具体应用实例 ,阐述了低压三电平大功率变频器的特点及改造中应注意的问题 。

The effect of ventilator for production of coal mine is produced and the traditional function is analyzed.It emphasize the meaning and effect of the alteration to frequency conversion for ventilator of coal mine. Integrate the material applying expatiats, the character of low voltage and high power inverter along with the matter that it should pay attention to in rebuilding. Thus it can offer the experience to alterate the ventilator of coal mine.
