摘要
在电厂、水泵站及钢铁工业中,风机、水泵类拖动系统每年要消耗大量电能。采用液力偶合器后,每年已为国家节电20亿kW·h以上。但从节能角度看,对交流电动机进行变频调速后产生的经济效益更为可观。随着国产高压大功率变频技术的日趋成熟及产品价格的不断降低,大力推广国产高压变频调速节能装置意义重大。最后通过具体数据说明推广使用高效率变频调速装置的重要性。
Drive systems for pumps and blowers consume huge amount of electric energy in power plant, pump station and steel industry as well. By using hydraulic fluid coupling technology more than two billion kW · h has been saved annually, however, from energy saving perspective, applying AC speed control for AC motor will bring even more savings in electric energy. With the proven development of domestic high voltage large capacity AC drive control technology and the cost advantage, it becomes more and more imperative to push forward for the technology in all applications. The imperative necessity of generalizing high efficiency variable frequency speed adjusting energy saving unit was explained by data analysis.
