Low-voltage Frequency Conversion Speed Regulation System

The system uses ABB ACS800 series transducer as main control equipment, specially designed for frequency conversion system of the hoisting equipment. The system has constant torque and low-speed starting 100% torque, speeding up stably and reliably. In the whole circulation, the system can effectively stop or remove the elastic vibration of the wire rope, guaranteeing accuracy of positioning and stopping, with error less than ±3cm. Main loop is 6-pulsation control mode, which can work according to set speed and hoisting requirements within four quadrants, regulate speed acceleration, constant speed and speed reduction of the hoist automatically, and has some protection functions of over-current, over-voltage, under-voltage, over-speed, etc. Besides, the system has some advantages of surge voltage control, energy saving, easy operation and maintenance. The system is universal to various hoists, which can be connected with various hydraulic stations. The system is widely used in lifting materials and staff in inclined shaft or silo of coal mine, metal mine and non-metal mine.

SDTDK Series Hoist Electric Control System

SDTDK series AC hoist electric control system consists of a main control console, a power cabinet (high-voltage, low voltage), a reversing cabinet (high-voltage, low voltage, frequency conversion, DC speed regulation), a relay cabinet, a power braking cabinet, a silicon-controlled speed-regulating cabinet, and a low-frequency power cabinet. The main control unit uses two high-reliability imported industrial computer, solving the problems of double wire system of safety loop perfectly. The main control functions are designed according to redundancy principle. The electromagnetic compatibility is designed and tested according to GB/T17626 (IEC801). The panel display uses touch-type color LCD to display all kinds of working curves of static/dynamic hoisting parameters, speed, force, etc. The system is matched with our technical results, such as cL-1 current testing module, KD-03 adjustable brake power braking module, etc., featured by programmable logic circuit, double wire system of safety loop, executive element modularization, color screen display of parameters, all-digital low-frequency power supply, visualized warning, programmable set speed, electronic executive elements, etc. The system is used in various hoists driven by winding rotor AC motor in silo and inclined hole. In such situations as multi-rope, multi-level, double machines, inclined shaft, multi-location, etc., the system works well.
