Low-Voltage Inverter Speed Control System
This system is a newly developed frequency control system specially for hoisting equipment with Swiss ABB ACS800 (or Wicken/Siemens) series frequency converter as the main control equipment. The system has constant torque, low-speed start 100% torque, smooth and reliable acceleration in the whole cycle can effectively limit or eliminate the elastic vibration of the hoisting wire rope, to ensure the accuracy of the stop in place, the error does not exceed ± 3cm. 6 pulsation control mode for the main circuit, can run in four quadrants in accordance with the predetermined speed map and hoisting requirements, to complete the hoist acceleration, equal speed, deceleration operation of automatic regulation, with Over-current, over-voltage, under-voltage and over-speed protection functions. It also has the advantages of suppressing surge voltage, energy saving and noise reduction, simple operation and convenient maintenance. It is versatile for different hoists and can be connected to different hydraulic stations. It can be widely used in metal and non-metal mines to lift the slant shaft or shaft, lower the material and transport the personnel.
