武钢炼钢总厂三分厂1号转炉高压给水泵电机自投产以来,只能全压起动,高速运行,造成电能浪费大,电机更换频繁。为降低能耗,保障转炉生产顺行,对其进行了变频改造,节约了电能,有效延长了电机在线运行时间,取得了较好的效果。 Since the high-voltage feed pump motor of No. 1 converter of No.1 plant of WISCO Steelmaking Plant has been put into operation, it can only start at full pressure and run at high speed, resulting in large power waste and frequent motor replacement. In order to reduce energy consumption, to ensure the smooth progress of converter production, frequency conversion of its transformation, saving energy, effectively extending the online operation of the motor, and achieved good results.
