变压器的设计及检测研究.doc

摘要 变压器是输电系统中重要的设备。电从发电机出来以后，通过升压变压器送到电网，在经过几次降压后才至用户，其间共通过变压器4~5次，甚至8~9次，损耗很多。这些年来，随着能源的日益紧张，对变压器这一重要的输电设备进行节能设计也越来越受到人们的关注和重视。S10-TM-500/10变压器 对变压器进行节能设计的原则就是满足性能指标条件下，降低变压器的损耗及材料成本。在具体设计过程中，往往需要反复调整和计算，因为降低损耗和降低材料成本在某种条件下又是相互矛盾的，反复调整和计算就是使得全局优化的过程节能变压器与普通变压器设计的相同，但参数选择偏重点不同 关键词: 变压器节能损耗 Abstract The transformer is the main equipment in the transmission system. The electricity which comes from the generator ,through the step-up transformer to the grid,after several times decompression to the users,though the transformer 4~5times in total,even 8~9 times,losssing so much. In recent years, with the energy tensing increasingly, people paid more and more attention to this important power transmission equipment. The S10-TM-500/10 transfomer is an energy-conservation transformer. The energy-conservation designing principle of three-phase transformer required that the loss of the transformer and the cost of the effective material were reduced with the performance indexes met. In the course of the concrete design, adjusting and calculating are needed repeatly,because it is contradictory for each other to reduce various loss and the material costs under a certain condition.so, the course of adjusting and calculating repeatly is the course of making the overall situation optimization ,so as to achieve the purpose. The design procedure of energy-conservation transformer and ordinary transformer is the same,and they are different in the choose of parameter, all of these need careful analysis and consideration.These will make detailed introduction in the course of design concretely.
