【摘要】 结合按电度表计费的电度电价、按投运变压器容量计费的基本电价、变压器市场价格、银行利率等因素,以S9系列10KV/0.4KV变压器为例,推导出变压器的经济负荷率。并注意到,对同一设计系列变压器而言,随着其容量的增长,铜损、铁损和价格都在增加,而这些数据又都是离散的,为便于分析,文中分别把铜损、铁损和价格表示成变压器容量的函数,给变压器的运行成本分析带来了方便。更多还原

【Abstract】 With the analysis of S9 Series 10KV/0.4KV transformer,the transformer’s economical load rate is deduced.And electrovalence in accordance with ammeter,basic electrovalence in accordance with transformer’s capacity,the market price of transformer,and the bank’s interest rate are considered.To the same series of transformer,with the growth of the capacity,the copper loss,iron loss and the price of the transformer are all in corresponding increasing.These dates are discrete.To predigest the analysis,the paper denotes the copper loss,iron loss and the price of the capacity’s function,which brings convenience to the transformer running cost analysis.更多还原
