基于DTC的大倾角带式输送机控制系统设计

Design on Control System of High Inclined Belt Conveyor Based on DTC

针对28°以上倾角的带式输送机启动加速度过大易引起物料下滑,较大的动张力易使输送带撕裂的问题,提出将直接转矩控制(DTC)技术的变频调速应用于大倾角带式输送机控制系统中,介绍了直接转矩控制原理,并成功地将其应用于阜新海州立井煤矿。实践检验证明,大倾角带式输送机控制系统启动转矩大,且运行平滑,将带式输送机的最大倾角拓展为35°。

According to the material downward sliding occurred by the start speeding too higher of the belt conveyor over 28°and the conveyor belt tearing easy occurred by the higher tension,the frequency converted speed control of the direct torque control technology was proposed and applied to the control system of the high inclined belt conveyor.The paper introduced the work principle of the direct torque control（DTC） technology,which was successfully applied to the underground mine of the Fuxin Haizhou Mine.The practice inspection showed that the control system of the high inclined belt conveyor could have high start torque and smooth operation and could ensure the belt conveyor to have the max transportation inclination of 35°.
