摘要
通过在矿井提升主电动机冷却风机电气控制系统中采用变频调速和可编程控制,将原来以工频固定转速系统的风机改造成根据提升主电动机内部温度控制的变频调速系统,以实现节能和增加冷却系统的使用寿命。
The paper introduces the application of frequency transformer and programmable controller in the cooling system of winding motor. It makes the air machine of cooling system from fixed rotational speed in power frequency to speed control in frequency conversion, and gets to power economy and increases the life of the cooling system.
