| Abstract: | In view of the problem that the distribution transformers selected for subway stations were usually oversized,authors of the paper investigated the working conditions of all equipment commissioned in subway stations and analyzed main factors affecting the selection of economic capacity of transformers in detail.Based on the calculated results of general loads for a typical station,the present value method was adopted to calculate the overall cost of different capacity distribution transformers in the subway... |
