BPJ series mine flameproof and intrinsically safe AC frequency converter

Suitable for the power grid of AC 50HZ and rated voltage 660 / 1140V in coal mine. It is specially used for the drive of permanent magnet synchronous electric roller. The power range is: 55-250KW inverter of 660V, BPJ series mine flameproof and intrinsically safe AC frequency converter55-630KW inverter of 1140V (two quadrant, four quadrant ), the product has the following characteristics :

International advanced vector control technology is adopted, so it is characterized by high speed regulation accuracy, fast dynamic response, and can output no less than 2.2 times of the rated torque,suitable for heavy load starting occasions. 

 Imported components, ABB, Siemens, Infineon and other well- known brands are used for the main circuit and control circuit of the inverter. 

 Input and output harmonics are effectively reduced to meet EMC standard requirements by using non-inductive laminated busbar, Long life thin film capacitor and the design of excellent electromagnetic. Output cable length can be 0 - 1500 meters. 

 10.4 inch display is equipped and man-machine dialogue is simple and display information is rich. 

  A sixteen-key matrix keyboard is equipped on the front door, which makes it convenient to debug. Modular and reasonable layout makes it easy to maintenance ; 

 Protection functions including: Overload, under voltage, phase loss, overheating, power imbalance,short circuit, leakage blocking, over temperature, and power failure recording functions are provided; 

Multi-device of master-slave operation, dynamic power balance and remote data transmission and monitoring are achieved by Optical fiber communication.
