摘要
利用通用变频器对风机、泵类负载进行控制,能有效地节约能源,但在为现场电动机选配变频器时,要根据实际情况合理地选用变频器类型,准确地计算出所需变频器额定容量和额定电流,以实现最佳性能价格比。
In variable-speed AC drives of air-blower and pump, the power can be used more effectively. When the general-purpose inverter is prepared for the existing motor,it is necessary to select the types of inverter according to the actual situation firstly,then it is important to calculate the rated value of converter accurately, to achieve the best cost performance.
