摘　　要：大庆油田电网中35kV级变压器有485台,其中大部分都是S7型高耗能变压器,累计容量达22.59×104kVA,属淘汰落后产品。电能通过变压器和输电线路要损失10%左右,而变压器损耗约占7%,有很大的节能潜力。针对目前在用的各种高耗能变压器现状,通过对S7型35kV级高耗能变压器优化设计,合理改造,使变压器整体技术水平达到国家低耗能变压器技术标准,并结合节能技术改造情况进行经济效益分析,为油田高耗能变压器产品节能技术改造提供参考。There are 485 35 kV transformers in Daqing Oilfield Power Grid. Most of them are S7-type high energy consumption transformer, the cumulative capacity is 225, 900 kVA. And they are regard as backward products.There is 10% loss when electric power going through transformers and transmission lines, and the transformer loss accounts for about 7%. So it has large energy saving potential in this area. According to the current status of high energy consumption transformers, the overall technical level of the transformer can achieve national lowvoltage consumption transformer technical standards by optimal design of S7 type 35 kV high energy consumption transformer. And also economic benefits analysis which combined with energy-saving technological transformation can provide reference for energy-saving technological transformation of oilfield high energy-consuming transformer products.
