摘要
通过比较转子串电阻与变频器在矿井提升机系统中电能的损耗,得到了变频技术在节能方面比转子串电阻具有很大的优势。在大型煤矿中,对原有转子串电阻系统进行变频改造,会有很好的经济效益。
By comparing the power lose of series-wound resistance and frequency conversion in mine hoist, it＇s obviously that frequency conversion has a great advantage in energy-saving than series- wound resistance. In large mines, it will be a very good economic benefits by transforming the series-wound resistance to frequency conversion.
