Abstract：Taking the mine owned by Jinneng Holdings Equipment Manufacturing Group as the research object,the compatibility issues of the power fast switching device and variable frequency speed regulation device for the main ventilation fan were analyzed,focusing on their application.The study found that the variable frequency speed regulation device for coal mine main ventilation fans achieves ener-gy-saving and intelligent speed regulation through frequency conversion,which is based on sacrificing the function of the power fast switching device to a certain extent.There is a certain degree of incompatibility between the two functions.For main ventilation fans in-stalled with power fast switching devices,it is necessary to carefully choose the variable frequency speed regulation device from the per-spective of reliability first,economy and intelligence second.
