20kV变压器技术手册

20kV级配电变压器技术手册120kV级配电变压器产品介绍随着电力负荷的增长,10kV配电系统已不能很好地满足要求。1996年在中国苏州-新加坡工业园区率先采用了20kV配电电压，2007年在江苏省开始试点推广20kV配电。我国中压配电网如能将10kV升压到20kV，线路能量损耗可减少四分之三，而且可以解决10kV电压等级存在的其它许多问题，如，能节约变电站数量和土地，减少线路走廊资源等。在此情况下我公司自主开发研制了20kV级配电变压器。S11-M系列油浸配电变压器，电压等级20kV，容量50～2500kVA，已通过国家变压器质量监督检验中心的全部试验。在10kV系统向20kV系统转变的过程中，存在现在只有10kV供电系统，但不久又要改为20kV系统供电的情况。为了用户不必作二次投入，节约开资，我公司又专门研发了10kV与20kV双电压转换变压器。S11-M系列油浸双电压配电变压器，电压等级20kV（10kV），容量50～2500kVA，产品已通过国家变压器质量监督检验中心的全部试验。产品的主要特点有：1.10kV与20kV转换后联接组别不变，分接电压不变，不同于以前Dyn11转换为Yyn0(在6kV与10kV之间的转换)。2.变压器绕组安匝排列合理，抗短路能力强。3.两种电压运行状态下无闲置匝数，变压器负载损耗低。4.用户使用方便，只需转换设置在箱盖上的两位置开关就能完成。SDC（B）10系列20（10）低噪声低损耗树脂浇注线圈双电压干式变压器，电压等级20kV（10kV），容量400～3150kVA。其中高压绕组为结构完全相同的两部分，进、出电端子引到高压线圈外部，串联时作为20kV级、并联时作为10kV级配电变压器使用。20kV级油浸式配电变压20kV级干式配电变压器20kV（10kV）双电压干式变压器20kV（10kV）双电压油浸式变压器2SDCB10-630/20（10）SDCB10-1600/20（10）S11-M-1600/20S11-M-630/20-10320kV级S11型无励磁调压配电变压器技术数据表TechnicalDataforS11TypeOff-circuitDistributionTransformerswith20kV额定电压（kV）RatedVoltage型号Type额定容量RatedCapacity（KVA）高压H.V.(kV)高压分接范围TappingRangeofH.V低压L.V.(kV)联结组标号ConnectionSymbol空载损耗No-loadLoss(kW)负载损耗LoadLoss(kW)空载电流No-loadCurrent(%)短路阻抗Short-circuitImpedance(%)S11-M-50/20500.131.011.0S11-M-80/20800.181.370.9S11-M-100/201000.21.650.8S11-M-125/201250.241.980.8S11-M-160/201600.292.420.7S11-M-200/202000.332.860.7S11-M-250/202500.43.350.7S11-M-315/203150.484.010.6S11-M-400/204000.574.730.6S11-M-500/205000.685.660.65S11-M-630/206300.816.820.6S11-M-800/208000.988.250.5S11-M-1000/2010001.1511.330.5S11-M-1250/2012501.3613.20.5S11-M-1600/2016001.6415.950.5S11-M-2000/2020001.9419.140.4S11-M-2500/20250020±5%±2×2.5%0.4Dyn11Yyn02.322.220.46注：1250kVA及以上的变压器采用散热片带油枕结构。样本数据仅供参考，公司保留数据变动的权力，并接受特殊订货。重量Weight（t）外型尺寸（mm）OverallDimension号型Type额定容量RatedCapacity（KVA）油重Oil总重Total长L宽W高H轨距TrackSpacing(mm)S11-M-50/205011045011307001180400×400S11-M-80/208013050011407101190400×450S11-M-100/2010015060011507201200400×450S11-M-125/2012517575011707301220400×550S11-M-160/2016019090012407401240550×550S11-M-200/20200200100013507801260550×550S11-M-250/20250220110014008001280550×650S11-M-315/20315260130014608201300550×650S11-M-400/20400320150015108301380550×750S11-M-500/20500350170015508501400660×750S11-M-630/20630400210017309501500660×850S11-M-800/208004502550180010001600660×850S11-M-1000/2010005002900190011001700820×850S11-M-1250/2012506003400220017502300820×850S11-M-1600/2016008004700225019502410820×900S11-M-2000/20200090049502350210024501070×1070S11-M-2500/202500100057502400215025001070×1070420kV级配电变压器外形尺寸图ABCcba0520kV级S11型无励磁调压双电压配电变压器技术数据表TechnicalDataforS11TypeOff-circuitDual-ratioDistributionTransformerswith20kV额定电压（kV）RatedVoltage型号Type额定容量RatedCapacity（KVA）高压H.V.(kV)高压分接范围TappingRangeofH.V低压L.V.(kV)联结组标号ConnectionSymbol空载损耗No-loadLoss(kW)负载损耗LoadLoss(kW)空载电流No-loadCurrent(%)短路阻抗Short-circuitImpedance(%)S11-M-100/20-101000.21.650.8S11-M-125/20-101250.241.980.8S11-M-160/20-101600.292.420.7S11-M-200/20-102000.332.860.7S11-M-250/20-102500.43.350.7S11-M-315/20-103150.484.010.6S11-M-400/20-104000.574.730.6S11-M-500/20-105000.685.660.65S11-M-630/20-106300.816.820.6S11-M-800/20-108000.988.250.5S11-M-1000/20-1010001.1511.330.5S11-M-1250/20-1012501.3613.20.5S11-M-1600/20-1016001.6415.950.5S11-M-2000/20-1020001.9419.140.4S11-M-2500/20-10250020(10)±5%±2×2.5%0.4Dyn11Yyn02.322.220.46注：1250kVA及以上的变压器采用散热片带油枕结构。样本数据仅供参考，公司保留数据变动的权力，并接受特殊订货。重量Weight（t）外型尺寸（mm）OverallDimension号型Type额定容量RatedCapacity（KVA）油重Oil总重Total长L宽W高H轨距TrackSpacing(mm)S11-M-100/20-1010019072012207601270400×450S11-M-125/20-1012517575013008001290400×550S11-M-160/20-1016019090013508301310550×550S11-M-200/20-10200230105014308601330550×550S11-M-250/20-1025026123015008801380550×650S11-M-315/20-10315290135015309101420550×650S11-M-400/20-10400350155015109501450550×750S11-M-500/20-10500400175015509801480660×750S11-M-630/20-10630450215017309901500660×850S11-M-800/20-108005002600180010501580660×850S11-M-1000/20-1010005502950193011601640820×850S11-M-1250/20-1012506503450220018502300820×850S11-M-1600/20-1016008504750225020502410820×900S11-M-2000/20-10200090049502350220024501070×1070S11-M-2500/20-102500105058002400225025001070×1070620kV级双电压配电变压器外形尺寸图BCA串并联开关分接开关0abc720kV级315～3150kVA干式配电变压器1、型号标志SC(B)10–xxxx/**额定高压电压(kV)额定容量(kVA)性能水平代号低压箔式线圈三相环氧浇注2、产品标准GB/T10228，GB1094.11-2007，IEC600076:2004，DIN42523额定高压：20(22、24)联结阻别：Dyn11orYyn0额定低压：0.4kV绝缘水平：LI125AC50/AC3P0PkUkI0LPGt尺寸(mm)型号(kw)kw(75)℃%%dB(A)kgabcdefghK1D低压端子SC10-315/200.883.30060.7501420131075012786601339122526841045018aSC10-400/200.983.88060.6501560132075012886601349123528042145018aSC10-500/201.224.62060.6501790137075013256601386128028242547018aSCB10-630/201.355.61060.5502130145075014536601393135323238550018aSCB10-800/201.546.66060.5522450154091014308201370132830539453018bSCB10-1000/201.817.70060.5522880157094015638201493145131139853518bSCB10-1250/202.289.13060.5523310162094016838201613157131340455522bSCB10-1600/202.4011.6660.5524500185094017288201668161733237062022cSCB10-2000/203.1214.2260.5525200188094019658201801175233637564022dSCB10-2500/203.7116.0060.453610020101230198710701820
