摘要
以金源煤矿矿井主通风机改造为例,论述了主通风机变频节能与在线监测系统的跟进,提出电容滤波可以消除变频对温度采集模块恒流源芯片的谐波污染。
According to the main fan transformation of Jinyuan Coal Mine, discusses main fan frequency- conversion, energy saving and advancement of online monitoring system, presents that capacitor filtering can eliminate harmonic pollution of temperature collection module constant current fountain chip causing by frequency - conversion.
