1. Function

BPJ-400(250,110)/1140(660) mine flame-proof and intrinsically safe AC frequency converter is used in underground mines with explosive gas (methane) and coal dust. Main spare parts such as IGB T, filter capacitor, control core adopt imported brands to ensure reliable longtime operation. This series adopt vector control technique with perfect motor protection and good speed adjusting to realize soft start and soft stop of the motor . According to the load circumstances, it can automatically adjust the motor speed and reduce the reactive impact of the motor starting on the grid. Meanwhile, through peripheral sensor , it can realize variable dynamic control to achieve the purpose of energy saving. Applicable to explosion-proof mine hoists, belt conveyor , scraper conveyor , pump station, fan etc. in the underground mines
