两部制电价与变压器容量选择

DUAL PRICING OF ELECTRICITY AND TRANSFORMER CAPACITY SELECTION

实行两部制电价的矿山企业，变压器容量选择与经济性之间存在一定的关系，按变压器最经济运行来选择容量，将导致企业承担基本电费过重，然而这种方式选择变压器容量在不少国有矿山一直沿用，就这方面本文作些分析，宜在选择变压器时作参考。

There is relationship between transformer capacity and economy when dual pricing system is employed at a mine. If economic operation of transformer is used to select capacity, an enterprise will bear more basic electricity cost, which is the most case at mines. This paper tries to analyze this aspect, which is just for reference when selecting transformers.
