BPBJV-□/10 Mining Explosion-proof & Intrinsically Safe VFD Transforme adopts an integrated design of phase-shifting transformer and frequency converter, featuring a compact structure and high power density. In underground coal mine environments with explosion hazards such as coal dust and gas, it drives motors for speed regulation operation, realizing functions including heavy-load soft start and soft stop, and stepless speed regulation for electric motors. It offers advantages such as low starting current, high output torque, smooth speed adjustment, small impact on the power grid, and easy centralized control. It is widely applicable to constant-torque loads such as scraper conveyors, belt conveyors, winches and vertical shaft hoists, and can also be used for constant-power loads including underground coal mine fans and water pumps.
