牛山污水厂变压器减容

Volume Reduction of Power Transformer in Niushan Sewage Factory

指出了日处理3万t污水的牛山污水厂安装了一台1000kVA干式电力变压器,但实际运行最大的总功率是410kW,存在严重的浪费。基于此,运用清洁生产原理,提出了相应方案,通过把一台1000kVA干式电力变压器减容为500kVA,每月可节省11500元基本电费,而且能提供足够的电能满足污水厂一期运行需要。

There is a dry--type power transformer of 1000 kVA which treats 30,000 tons of sewageper dayin Niushan Sewage Factory. However,the maximal total power is 410 kw in operation, so thatthere is serious power waste.According tothe principle of cleaning production, a dry--type 500.kVA power transformer was installed instead of the 1000--kVA one.It could save Yl1500 ofhasic electricity a month as well as provide enough power to operate the sewage factory for one period.
