摘要
为了提高煤矿井下尤其高瓦斯矿井局部通风机的供电质量,提出了对井下局部通风机的专用电源采用专用线路从地面变电所供电。该方法消除了井下掘进工作面瓦斯超限的安全隐患,在矿井供电系统中得到了广泛的应用。
For improving the quality of power supply to local fan in mine especially in high gassy mine, this paper proposed some concrete measures. Practice shows that the method to supply power to local fan by a private line from the substation on the ground is effective. The method can eliminate the hazard of gas to limit, and can be applied widely.
