Discussion on the Transformer′s Economical Lode Rate

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.
