阐述了发电厂锅炉送风机、引风机采用变频调速可获得的技术优势及经济效益。为了解决大型风机在低负荷时产生的巨大浪费及启动电流对风机的冲击 ,尝试采用无谐波高压变频器 ,不仅解决了安全、节能问题 ,而且减少了由此造成的谐波 ;同时又进一步分析了锅炉送风机采用变频调速后产生的经济效益。充分说明了采用完美无谐波交流马达变频器是解决发电厂锅炉风机现阶段存在问题的一种有效的方法。
Describes the power plant boiler blower, induced draft fan frequency control technology available and economic benefits. In order to solve the huge waste generated by large fan at low load and the impact of starting current on the fan, trying to adopt the non-harmonic high-voltage frequency converter not only solves the problems of safety and energy saving, but also reduces the resulting harmonics; meanwhile, further Analyzed the economic benefits of boiler blower adopting frequency conversion speed regulation. Fully illustrates the use of a perfect non-harmonic AC motor inverter is to solve the power plant boiler fan at present stage of an effective method.
