资料介绍

变频器对电机转速的控制既可以满足生产工艺的需求,也可以减少设备不必要的机械磨损和起到节能降耗的作用,因此变频器在我中心11个洗煤厂有着广泛的应用,如对泵的液位的自动控制,清扫水的恒压控制,皮带的调试运行等,应用品牌也较多,主要涉及ABB低压,施耐德高低压,西门子高低压变频器。变频器在使用中也会出现各种各样的故障,文章主要从变频器的主电路着手,重点分析变频器的故障现象、检修思路和检修方法。

The control of motor speed by frequency converter can not only meet the requirements of production process, but alsoreduce the unnecessary mechanical wear of equipment and play the role of saving energy and reducing consumption. Therefore, thefrequency converter has been widely used in 11 coal preparation plants in our center, such as the automatic control of the pump level, the constant pressure control of cleaning water, the commissioning of belt, and so on. There are many application brands, mainlyinvolving ABB low voltage, Schneider high and low voltage, and Siemens high and low voltage frequency converter. Frequency converter in use will also appear a variety of faults. This paper, from the main circuit of the frequency converter, mainly f...
