摘　　要：高压变频器具有十分明显的节能效果,但其可靠性还不能完全满足发电设备的要求。提出了变频器故障旁路的方法,经在670 t/h锅炉吸风机上实际应用,取得了满意的效果。The high - voltage Frequency converter has obvious energy- saving effect, but its reliability still can not completely satisfy the requirements of power generation equipments. Hence, a method of by- passing the trouble of frequency converter has been put forward, and being used in practice for induced draft fan of a 670 t/h boiler, obtaining satisfactory result.
