本文介绍了合康HIVERT-Y06/173高压变频器在除尘风机中的应用。阐述变频调速节能原理和节能效果。通过改造,实现除尘风机的高效运行,达到节能降耗的目的。高压变频调速系统采用直接“高一高”变换形式,变频器包括1台内置的PLC,用于柜体内开关信号的逻辑处理,以及与现场各种操作信号和状态信号的协调,根据需要扩展控制开关量,增强了系统的灵活性。由变频器直接控制电机,可以任意设定时间来调速驱动除尘风机,风门可以全部打开,完全由转速调节流量,提高了传动效率。电机的电压、电流明显下降,电机输入功率明显减少,其使整个系统避免了全负荷启动时的大电流冲击,节电率在20%~70%之间。

This paper introduces the application of HIVERT-Y06/173 high voltage inverter in dust removal fan. The energy saving principle and effect of variable frequency speed regulation is expounded in this paper. Through the transformation, it achieved the efficient operation of dust fan, and achieved the purpose of saving energy and reducing consumption. High voltage variable frequency speed regulation system using direct ＂high high＂ transform, frequency converter includes a built-in PLC for cabinet switch signal of the logic processing, and with all kinds of field signal and operation state signal coordination, according to the need for expansion volume control switch, enhance the flexibility of the system. By direct control of the inverter motor can be arbitrarily set the time to control and drive the dust removal fan, air damper can be fully open, completely by adjusting the rotating speed of the flow and improve the transmission efficiency. The voltage and the current of the motor are obviously decreased, and the input power of the motor is obviously reduced, so that the whole system can avoid the large current impact during the whole load starting, and the power saving rate is between 20% and 70%.
