煤矿地面主通风机是矿井生产的生命线,素有“矿井之肺”的称号,担负着煤矿安全生产的重任。在矿井主通风机改造过程中,针对控制技术的研究分析与应用,对提高主通风机自动化控制水平具有实际意义。1老系统的运行状况1.1主通风机供电系统老主通风机系统包括高压供电部分、软启动部分、高压变频器部分、切换部分,系统结构庞大、复杂,给主通风机正常运行、每月倒机及故障情况下的处理造成了极大的不便。主要缺点有以下4方面
The main ventilator on the ground of coal mine is the lifeline of mine production. It has the title of “lung of mine shaft” and shoulders the heavy responsibility of coal mine safety production. In the process of mine main ventilator reformation, research and analysis and application of control technology have practical significance to improve the level of automation of main ventilator. The operation of the old system 1.1 The main fan power supply system The main fan system includes high-voltage power supply section, soft-start section, high-voltage inverter section, switching section, the system structure is large and complex, to the main fan normal operation, monthly down Machine and fault handling caused great inconvenience. The main drawbacks are the following 4 aspects
