基于富士变频器带式输煤机变频调速控制

Belt Type Conveyer Variable Frequency Speed Regulation Control Based on Fuji Inverter

带式输煤机的阻转矩属于恒转矩负载,这类负载采用通用变频器控制的目的是实现设备自动化、提高劳动生产率、提高产品质量。分析了恒转矩性能的通用变频器的选型,同时充分考虑低速、大转矩情况下为提高转矩提升能力而使电压补偿提的过高及过电流保护动作,必要时应将通用变频器的容量提高一档,或者采用具有矢量控制或直接转矩控制的通用变频器。

The resistance belt drive turn coal are constant torque load, such load frequency control using a common objective is to achieve equipment, automation, improve labor productivity, improve product quality. The performance of general-purpose constant torque converter selection was analyzed, taking full account of low-speed, high torque situations to enhance the ability to increase torque to mention leaving the high voltage compensation and over-current protection action, if necessary, should be selected with GM should increase the capacity of a file converter, or the use of the vector control or direct torque control of general purpose inverter.
