摘要
提出在采掘工作面负荷大的千万吨特大型矿井采用三回路双联络高压专用供电系统,其中一回路作为局部通风机高压专用线路,兼顾备用电源的功能。既提高了矿井局部通风机供电可靠性,又避免了大负荷采掘工作面负荷波动影响局部通风机的情况,从而保证了大负荷采掘工作面生产的连续性。
The paper puts forward three-loop double-contact of mine special power supply system with high voltage used by mining working face with large load of ten million tons of oversize mine, a primary circuit is employed as high voltage auxiliary fan dedicated line and the standby power. It can not only improve the power supply reliability of mine local ventilator, but also avoid the situation that load fluctuation affects local ventilator in mining working face with large load, and ensure the continuity of production in mining working face with large load.
