摘要
研究了矿井主通风机应用变频调速装置后的供电方案,为确保变频装置故障后通风机的自动切换运行,设计了工频供电控制自动切换方案,实现了矿井主通风机连续可靠运行。
In this paper,power supply scheme based upon the application of frequency converter speed regulating technology for main mine fan is studied. To ensure an automatic switchover operation of the main fan after a fault of the frequency converting device,an automatic switchover scheme is designed for the power supply control system hence a non-stop and reliable operation of main mine fan is realized.
