The BPJV1 Series Flame-proof and Intrinsically-safe High-voltage VFD for Mining Applications features three-level ANPC inverting technology, with high power, high voltage, low loss IGBT , high reliability, high efficiency and high-performance vector control technology is achieved. A 12-pulse low-harmonic rectifier technology is used, with a standard dv/dt filter at the output. A three-level topology is adopted for the primary circuit, with fiber optic isolation used for the IGBT triggering signals. Power electronic modules are cooled by water cooling technology. The maximum starting torque and maximum current are up to 2.5 times the rated values, making the product suitable for heavy loads and high torque equipment. The distance from the inverter to the motor can be up to 3-5 kilometers. The product features master-slave dynamic load-sharing control, and fast load dynamic power (torque) balancing. Copper cable connectors are used for input and output cables to enter and exit the cabinet, making it convenient for on-site installation and commissioning.

The 3.3kV Flame-proof VFD series covers the following power ratings: 855kW, 1000kW, 1250kW, 1400kW and 1600kW. Different ratings are available in single circuit configuration, with two or three-module combined configuration available. This flexible configuration makes the products suitable for coal mine armored face conveyors, belt conveyors, emulsion pumping stations and other applications.
