变频器综合实践第6讲 变频节能工程的综合实践

应用变频调速,可以大大提高电机转速的控制精度,使电机在最节能的转速下运行。在实际使用中,风机泵类等通用设备年消耗能源占全国总能耗的50％以上,总体能源利用效率比国外先进水平低10％～15％。因此,使用变频器调速节能的潜力非常大。

The Comprehensive Practice of AC inveter

Using inverter control technogly, the motor can running under the high speed precision. AC motor can save energy with the specd cutdown.In fact, the energy consumring of fans and pumps will be above 50% among the total energy consumption. The ratio of the energy utilization is 10%-15% lower than other countries. So the potential of energy saving is great with using AC inverter.
