[毕业设计]6300KVA电力变压器设计(1)

6300KVA电力变压器设计学生姓名：学生学号：院（系）：年级专业：指导教师：助理指导教师：二〇〇八年五月摘要现代化的工业企业，广泛地采用了电力作为能源，电能都是由水电站和发电厂的发电机直接转化出来的。发电机发出来的电,根据输送距离将按照不同的电压等级输送出去，就需要一种专门改变电压的设备，这种设备叫做“变压器”。见于变压器的现状和发展趋势，一些新技术、新材料、新工艺的应用也层出不穷。目前变压器行业的新材料和新技术在不断发展，除低损耗变压器、非晶和金铁心变压器、干式变压器、全密封变压器、调容量变压器、防雷变压器、卷铁心变压器、R型变压器、单相变压器、有载调压变压器、组合式变压器、箱式变压器外还有硅油变压器、六氟化硫变压器、超导变压器等。电力变压器是发、输、变、配电系统中的重要设备之一，它的性能、质量直接关系到电力系统运行的可靠性和运营效益,所以电力变压设计是一个很值得我们去研究的课题。关键词变压器，铁心，线圈，损耗，油箱，温升，重量ABSTRACTModernizationofindustrialenterprises,thewideruseofelectricityasasourceofenergy,electricityfromhydropowerstationsandpowerplantsarethegeneratorsdirectlyintothem.Senttotheelectricgenerator,accordingtotransmissiondistanceinaccordancewiththedifferentvoltagetransmissionout,weneedachangeinvoltagespecializedequipment,suchequipmentiscalledTransformer.Transformerseenatthecurrentsituationanddevelopmenttrends,newtechnologies,newmaterials,newtechnologyapplicationsareendless.Thecurrenttransformerindustryofthenewmaterialsandnewtechnologiesindevelopment,withtheexceptionoflow-losstransformers,amorphousandthecoretransformers,dry-typetransformers,allsealedtransformers,fortransformercapacity,minetransformers,woundcoretransformer,R-typetransformers,single-Phasetransformer,OLTCtransformers,modulartransformers,box-typetransformers,therearesiliconeoiltransformers,SF6transformers,suchassuperconductingtransformer.Itisapowertransformer,lose,change,powerdistributionsysteminoneofthekeyequipment,anditsperformance,quality,directlyrelatedtothereliabilityofpowersystemoperationsandoperatingefficiency,transformerdesignisaveryworthyofourstudyofSubject.Keywordstransformers,core,coil,loss,thefueltank,temperature,weight目录摘要………………………………………………………………………………………ⅠABSTRACT……………………………………………………………………………………Ⅱ1课题背景.........................................错误!未指定书签。1.1研究意义.....................................................................................................................................错误!未指定书签。1.2国内外发展状况.........................................................................................................................错误!未指定书签。1.2.1国外发展状况················错误!未指定书签。1.2.2国内发展状况················错误!未指定书签。1.3变压器的发展方向···············错误!未指定书签。2变压器设计前的准备...............................错误!未指定书签。2.1做好变压器设计应注意的问题..................................................................................................错误!未指定书签。2.1.1．熟悉国家标准与-··············错误!未指定书签。2.1.2熟悉产品规格及技术用户的要求········错误!未指定书签。2.1.3变压器设计计算步骤·············错误!未指定书签。2.2主要材料、结构的确定..................................................................................................................错误!未指定书签。2.2.1主要材料··················错误!未指定书签。2.2.2变压器主要结构的确定············错误!未指定书签。3电磁计算.........................................错误!未指定书签。3.1额定电压和额定电流的计算......................................................................................................错误!未指定书签。3.2铁心直径的选择..........................................................................................................................错误!未指定书签。3.2.1影响铁芯直径选择主要因素··········错误!未指定书签。3.2.1截面的选择·················错误!未指定书签。3.2.2铁心截面的设计···············错误!未指定书签。3.3线圈匝数的计算..........................................................................................................................错误!未指定书签。3.3.1每匝电压te的确定··············错误!未指定书签。3.3.2初选每匝电压'et···············错误!未指定书签。3.3.3低压线圈匝数的确定·············错误!未指定书签。3.3.4高压线圈各分接匝数的确定和电压比校核对···错误!未指定书签。3.4、线圈型式的选择及线圈排列...................................................................................................错误!未指定书签。3.4.1线圈高度的估计···············错误!未指定书签。3.4.2线圈的确定·················错误!未指定书签。3.5导线的选择..................................................................................................................................错误!未指定书签。3.6线圈辐向尺寸的计算..................................................................................................................错误!未指定书签。3.7绝缘半径(见图3-4).....................................................................................................................错误!未指定书签。3.8阻抗电压计算..............................................................................................................................错误!未指定书签。3.9高压线圈数据计算......................................................................................................................错误!未指定书签。3.10低压线圈数据计算....................................................................................................................错误!未指定书签。3.11铁心计算(见图3-6)..............................错误!未指定书签。3.12空载损耗Po的计算.................................................................................................................错误!未指定书签。3.13空载电流%OI............................................................................................................................错误!未指定书签。3.14涡流百分数WK的计算............................................................................................................错误!未指定书签。3.14线圈对油温升的计算................................................................................................................错误!未指定
