Research and Application of Comprehensive Treatment of 10 kV System Capacitance Current in Xiegou Mining Area

通过对斜沟矿区开采多年来10 kV供电系统电容电流的增长情况研究,分析了导致斜沟矿区10kV系统单相接地电容电流过大原因,并根据斜沟矿区生产供电现状,采取了定制安装最大补偿能力为200 A的大容量成套消弧装置对10 kV系统单相接地电容电流进行补偿灭弧,并满足矿井未来采掘延伸后电容电流的增长需求,同时制定矿区电缆使用规定措施来进一步抑制矿区电容电流的增长。

Through the research on the increase of the capacitance current of 10kV power supply system in the mining of Xiegou mining area for many years,this paper analyzes the causes of the excessive single-phase grounding capacitance current of the 10kV system in Xiegou mining area,and according to the current situation of production and power supply in the Xiegou mining area,a large-capacity complete arc-extinguishing device with a maximum compensation capacity of 200A is used to compensate and extinguish the single-phase grounding capacitor current of the 10kV system,which meets the requirements in the future,the demand for the increase of the capacitance current after the extension of mining will be increased.At the same time,the regulation measures for the use of cables in the mining area will be formulated to further restrain the increase of the capacitance current in the mining area.
