节能和自动化,需采用变频电源控制感应电动机的逆变器,其性能指标被认为与其他电气或机械的调速装置一样,从而得到广泛应用。目前,迫切要求具有节能性能的泵、风机等设备调速运行。另一方面,由于电子技术的发展及生产效率的提高,引起成本下降等多方面的原因,进一步增强了上述这一必要性。逆变器,作为一种调速裝置,在本质上具有通用性,和电动机组合使用时,与其他调速装置比较,具有如下特点:
Energy-saving and automation, need to use inverter power inverter control induction motor, its performance is considered and other electrical or mechanical speed governor, which has been widely used. Currently, there is an urgent need for energy-saving pumps, fans and other equipment speed operation. On the other hand, the above-mentioned necessity is further enhanced due to various reasons such as the development of electronic technology and the improvement of production efficiency and cost reduction. Inverter, as a kind of speed control device, has the inherent versatility. When it is combined with the motor, it has the following characteristics compared with other speed control devices:
