This standard specifies the type, basic parameters and dimensions, technical requirements, test methods, inspection rules, markings, packaging and warranty period requirements of the YJVFG series mining explosion-proof and intrinsically safe high-voltage variable frequency speed regulating machine. This standard is applicable to the frequency conversion and speed regulation transmission system in which the mining motor and frequency converter are integrated, namely the YJVFG series mining explosion-proof and intrinsically safe high-voltage frequency conversion and speed regulation integrated machine (hereinafter referred to as the integrated machine), which is used for methane and explosive materials. Dusty coal mines drive scraper conveyors, transfer machines, crushers, belt conveyors and mechanical equipment with similar working conditions as prime movers.
