摘要
在分析煤矿带式输送系统控制要求的基础上,提出采用高压变频器的自动控制方案。该方案可以完成带式输送机控制系统的软启动,操作者可根据煤仓煤量的多少来调节变频器输出频率,从而调节了电动机的转速,达到了节能的效果。
Based on the analysis of control requirements of belt conveyance system in collieries, an automatic control scheme that adopted the high voltage inverter was proposed. The scheme could accomplish the soft start of control system for belt conveyance system. The operator could regulate the output frequency of inverter according to amount of coal in bunker, thus the rotary speed of motor could be adjusted to achieve energy saving.
