关键词：矿井扩能升级改造、供电系统方案、设备选型设计
冀中能源张家口矿业集团怀来于洪寺煤矿经批准进行扩能升级改造，产量达到0.15Mt/a（15万吨/年），委托河北曲正工程设计有限公司设计，本人参与设计资料的收集和改造设计的部分工作。
本设计就是针对该矿扩能升级改造中，对其井上下供电系统设备进行选型设计，将一部分作为本人的毕业论文。
设计的内容
⑴矿井概论：矿井概况、地面和井下形成的生产系统、通风与运输系统及采掘工作面的布署，及其对供电系统的要求和矿井的供电电源。
⑵全矿用电设备负荷统计和计算：对改造后矿井上下用电设备和负荷分别进行统计和按类计算负荷的容量。
⑶井上下供电系统的方案拟定：按照矿井对供电的要求，根据《煤矿安全规程》和《煤炭工业矿井设计规范》确定该矿的供电方案。
⑷地面配电室设备的选型：按照矿井供电和配电的要求，对地面配电室的设备选型（包括进出线路、电力变压器、高压电器、无功补偿等）设计。
⑸对地面供电系统主要节点的短路电流进行计算。
⑹对地面供电系统主要节点供电设备校验和保护整定。
⑺绘制全矿井的供电系统总图和地面变电站设备布置图。

Please input here to translate the contents of Yu Temple coal mine power supply system equipment selection design Abstract
key words: mine expansion upgrading, power system scheme, selection of equipment design
Jizhong energy Zhangjiakou Mining Group Huailai Yuhong Temple Mine approved expansion and upgrade and alteration, production reached 0.15Mt/a (150000 tons / year), commissioned by the Hebei music is engineering design limited design, I participated in the design of data collection and transformation of part of the design work.
This is designed for the mine expansion and upgrading, for the well of power supply system equipment selection of design, will as a part of my graduation thesis.

design contentThe introduction of mine: mine, ground and underground formation production system, ventilation and transportation system and mining face the array, and its demand for power supply system and the mine power supply.
the mine electrical equipment load statistics and Computation: after the transformation of mine on the electrical equipment and load were performed according to the statistical and computational load capacity.
the Inoue and underground power supply system plan: according to the mine to the power supply requirement, according to "coal mine safety regulations" and "code for mine design of coal industry" to determine the mine power supply scheme.
the ground power distribution room equipment selection: in accordance with the requirements of mine power supply and distribution,On the ground the distribution room equipment selection (including import line, power transformer, high voltage, reactive power compensation design).
the ground power supply system the main node of the short-circuit current calculation.
. On the ground power supply system the main node power supply equipment check and protection setting.
, drawing mine power supply system layout and ground substation equipment layout.
