DC-BANK装置在煤化工生产中的运用

Application of DC-BANK into Coal Chemical Industry

电网电压的波动俗称晃电,对化工连续生产威胁极大。本文就电网闪络作了阐述,并提出了化工生产中抗电网波动的解决办法。重点介绍了煤气化工艺关健设备煤浆泵变频器的抗电网波动的解决办法。DC-BANK不间断电源系统,是解决电动机不间断供电的一种新的解决方案。采用变频器达到对电动机的无级调速方案,在煤炭化工工艺中被大量应用。但是,由于市电电压暂降引起变频器停机而造成生产中止、停工现象经常发生,由此造成的人身安全、设备安全、环境安全,已超越经济利益而成为企业重点考虑的头等大事。如果选用本系统作为变频器的后备保护电源,则能完全避免市电电压暂降带来的危害,防止上述情况的重复发生。

Voltage fluctuationing Grid,so-called electric dazzling,usually threats greatly continuous chemical production.The article explains grid flashing,and puts forward ways to solve the problem of grid fluctuation in chemical fluctuation.Coal slurry transducer,key equipment in coal gasification technology,is elaborated as a way for dealing with grid fluctuation.DC-BANK UPS system is a novel way to supply electromotor with electricity continuously.The application of transducer into electromotor to realize non-grade speed adjustment is widely used in coal chemical technology.But transducers may stop working due to voltage sag,which,in turn,leads to the production cease or stop. In addition,the phenomena not only may result in profits loss,but also may endanger workers,equipment and environment,thus making it a fundamental matter that enterprises may consider.Choosing this system as a backup protecting power supply to transducers may avoid the harm in case of voltage sag,so that the above-mentioned damages may be prevented.
