煤矿综采工作面远距离供电的研究与实践

Research and practice of long-distance power supply in fully mechanized coal mining face

随着煤矿综采工作面朝着纵深方向发展,供电距离变长,对供电系统提出了更高的要求。以神农煤业供电系统为案例,详细介绍了综采工作面供电方式的选择,从变压器容量和型号的确定、移动变电站进线高压电缆与各机电设备供电电缆的型号选择、低压组合开关选择等方面详细阐述了远距离供电系统的设计方案。

With the development of the fully mechanized coal mining face in the depth direction,the power supply distance has become longer,and higher requirements have been placed on the power supply system.The selection of the power supply method of the fully mechanized mining face in Shennong Mine was introduced in detail from the determination of the capacity and model of the transformer,the selection of the high-voltage cable of the mobile substation and the power supply cables of various electromechanical equipment,and the selection of the low-voltage combination switch.The design scheme of long-distance power supply system was expounded.
