目前,国内火电厂中大量的6kV风机和水泵需要进行节能改造,节能改造最有效的技术手段就是采用高压变频器(电压为3~10kV,功率为250~4000kW)。
At present, a large number of 6kV fans and pumps in domestic thermal power plants need energy-saving retrofit. The most effective technical means of energy-saving retrofit is to use high-voltage frequency converters (voltage of 3 to 10kV and power of 250 to 4000kW).
