Aiming at the problem of safe power supply for high-voltage electrical equipment in coal mine underground environments containing explosive gases such as methane and coal dust,based on multi-level technology theory and explosion-proof theory,an explosion-proof high-voltage frequency converter was designed and successfully applied to belt conveyors.In addition,a solution using high-voltage frequency conversion speed regulation technology for belt conveyors was also provided.
