目前 ,日产万吨的综采工作面已在大量涌现。美、澳等国高产综采面的生产能力均达到 2 0 0 0t/h。为满足这样大的生产能力和适应高产高效的需要 ,应加大工作面的长度 ,同时要求综采工作面的设备不断增大容量 ,这也相应增加了输电距离和供电负荷。就采区供电电压能否满足负荷要求 ,采用阻抗计算法进行了理论上的计算 ,就将来电压的选择提出了建议 ,并进行了验算。
At present, Nissan million tons of fully mechanized mining face has emerged in large numbers. The productive capacity of high-yield fully mechanized mining areas in the United States, Australia and other countries all reached 2 0 0 t / h. In order to meet such a large production capacity and to meet the needs of high-yield and high efficiency, the working face length should be increased while the capacity of the fully mechanized mining face equipment should be continuously increased, which in turn increases the transmission distance and the power supply load. The mining area power supply voltage can meet the load requirements, the use of impedance calculation method for the theoretical calculations, the future voltage options made recommendations, and checked.
