为了能够快速有效地利用门式起重机在起重工作机构下降及减速制动时产生的能量,研制出了一种基于超级电容储能的势能再回收系统。该系统充分利用超级电容大功率快速充放电的特性,通过双向DC/DC功率单元快速回收起重机构的下降势能,并作为起重机构上升时所需的能量补给,可降低起重机工作能耗,提高能量利用率,达到节能降耗的目的。
In order to quickly and effectively utilize the energy generated by the gantry crane when the crane working mechanism descends and decelerates, a potential energy recovery system based on supercapacitor energy storage is developed. The system makes full use of the characteristics of supercapacitor fast charging and discharging at high power, quickly recovering the descending potential of the lifting mechanism through the bidirectional DC / DC power unit and reducing the energy consumption of the working of the crane as the energy supply required for lifting the lifting mechanism, Improve energy efficiency, to achieve the purpose of saving energy and reducing consumption.
