配电变压器容量选择与经济运行问题分析

在确定配电变压器的经济容量时,可借助于配电变压器能效分析评价的方法,并按照Se>Sjs的容量选择条件,对多种待选方案的经济性作出初步的分析判断。同时按照年电能损耗最小的原则,可在待选方案中,筛选出节能性最好的变压器容量来。在此基础上,对所选方案作出进一步的综合分析比较,可使所选配电变压器容量在综合效益的层面上,较好地实现经济性与节能性的相对统一。

Analysis on Distribution Transformer Capacity Selection and Economic Running

When determining the economy capacity of distribution transformer, it can be helped with the evaluation method of distribution transformer energy efficiency analysis and according to the capacity selection condition of Se 〉 Sjs to make preliminary analysis and judgement on the economy of multiple standby schemes. At the same time, the best energy efficiency distribution transformer ca- pacity can be screened out from standby schemes in accordance with the principle of minimum power loss. On this basis, further analysis and comparison to the selected schemes will make the selected distribution transformer to achieve better relative uniform between economy and energy saving on the side of comprehensive benefits.
