BPJ1-□/□K
Mine-used flameproof and intrinsically safe AC frequency converter
Purpose and scope of useApplication and range of application
BPJ1-□/□K mine-used flameproof and intrinsically safe AC frequency converter is a four-quadrant frequency converter, which is used in conjunction with DKB2-□/□ mine-used flameproof filter reactor and DKB3-□/□mine-used flameproof reactor. It is a high-tech product integrating all-digital variable frequency speed regulation technology and relevant heat dissipation technology. This product is suitable for AC 50Hz,motorPower11KW~800KW,Rated voltage660Vor1140VIt is used for the heavy-load soft start, soft stop and operation process control of variable-frequency asynchronous motors. The start, stop and process control curvescan be set to"S"type curves, linear curves, function curves and other curve forms. These curves can be adjusted according to the actual on-site working conditions, thereby reducing the dynamic tension on the equipment during start-upand the starting impact. It is mainly used for the soft start, soft stop and operation process control of motors in harsh environments such as underground coal mines, other mines, petroleum and chemical industries, as well as energy-saving applications. It is used for the variable-frequency speed regulation control of equipment such as underground coal mine hoists, endless rope winches, monorail crane winches, monkey cars and belt conveyors.
Product features Product features
Small starting current, little impact on the power grid, smooth starting speed, large starting torque and reliable operation;
Simple control operation, modular structure and convenient maintenance;
Heat pipe cooling or water cooling, users can choose according to their needs;
Equipped with communication interfaces such as RS485 and network ports, convenient for process control adjustment and optimization;
Obvious energy-saving effect, enabling economic operation;
It can directly control and protect the permanent magnet synchronous motor;
It is equipped with a 7 or 10-inch display screen, and has a built-in "debugging navigation system" and "maintenance navigation system", enabling users to perform simple self-debugging and maintenance work. It also has a "life alarm system" for components. When a component is approaching the end of its service life, an alarm will be issued to prevent production from being affected when the component is damaged due to reaching the end of its life.
