摘　　要：在负荷增长快、集中性强的地区建设变电站时,探索使用了大容量主变压器,开展了大容量变压器参数选择工作。对变电站内主变压器容量选用360 MVA或240 MVA进行了技术经济比较,认为采用360 MVA容量主变压器后,变电站可节省设备投资5%,占地面积节省14%左右,同时减少了运行维护工作量等。实际运行结果表明,设备运行情况良好,各项性能参数指标均在设计范围内。When building substations in the areas with fast load growth and strong concentration,large capacity main transformers are explored and used,and the parameter selection of large capacity transformers is carried out.Based on the technical and economic comparison of 360 MVA or 240 MVA main transformer capacity in the substation,it is considered that after 360 MVA main transformer capacity is adopted,the substation can save 5%of equipment investment,about 14%of floor area,and reduce the workload of operation and maintenance.The actual operation results show that the equipment operates well and all performance parameters are within the design range.
