矿用隔爆型智能负载跟踪变频调速装置的设计

Design of Flameproof Frequency Conversion Equipment of Intelligent Load Tracking for Coal Mine

针对矿用变频器在恒速运行工况下,所拖动的负载实时发生变化时无法实现节能的问题,设计了一种矿用隔爆型智能负载跟踪变频调速装置,该装置除具有通用变频器的功能外还具有负载跟踪功能,在线检测电动机负载率的变化,智能调节电动机的输入功率,使电动机始终在最佳状态下运行,实现节能的目的。

This paper designed a kind of flameproof frequency conversion equipment of intelligent load tracking for coal mine. The frequency converter for coal mine can not realize energy conservation in time of load changing when frequency converter running under the condition of constant speed. The e- quipment has function of load tracking on the basis of frequency converter. The equipment can monitor the change of load ratio for motor in line and regulating input power intelligently. The equipment real- izes energy conservation by means of making motor run under the best condition.
