摘要
昊华宇航化工有限公司采用高压变频器进行循环水泵电动机调速,节电效果显著。用具体实例介绍了高压变频器的选择、电器控制回路的设计、压力控制仪表回路的设计,并对节能效益进行了评价。系统不仅能节约用电费用,还具有恒压供水、减少大启动电流对供电系统及配电设备的冲击等优点。
Haohua astronavigation chemical co.,hd, adopts high voltage frequency converter for motor speed adjustment of water circulating pump and achieves obvious effect. The article introduces the converter selection, electrical control circuit design,pressure control instrument circuit design and assesses the energy conservation benefits. The system can realize saving tariff, supplying water at the constant pressure and reducing the impact of large start current for power supply system and distribution system.
