ABBBAILEYINIIT13INTKM01N***01变压器的短路阻抗，是指在额定频率和参考温度下，一对绕组中、某一绕组的端子之间的等效串联阻抗Zk＝Rk+jXk。由于它的值除计算之外，还要通过负载试验来确定，所以习惯上又把它称为阻抗电压。变压器的短路阻抗值百分比是变压器的一个重要参数,它表明变压器内阻抗的大小，即变压器在额定负荷运行时变压器本身的阻抗压降大小。变压器短路阻抗怎么计算？用试验求取的方法为：将变压器二次侧短路，在一次侧逐渐施加电压，当二次绕阻通过额定电流时，一次绕阻施加的电压Uz与额定电压Un之比的百分数,即：Uz%=Uz/Un×100%。变压器短路阻抗的大小有什么影响？变压器短路阻抗也称阻抗电压，在变压器行业是这样定义的：当变压器二次绕组短路（稳态），一次绕组流通额定电流而施加的电压称阻抗电压Uz。通常Uz以额定电压的百分数表示，即uz=(Uz/U1n)*100%。变压器的短路阻抗在运行中有什么作用？当变压器满载运行时，短路阻抗的高低对二次侧输出电压的高低有一定的影响，短路阻抗小，电压降小，短路阻抗大，电压降大。当变压器负载出现短路时，短路阻抗小，短路电流大，变压器承受的电动力大。短路阻抗大，短路电流小，变压器承受的电动力小。阻抗电压是涉及变压器成本、效率及运行的重要经济技术指标。同容量变压器，阻抗电压小的成本低，效率高，价格便宜，另外运行时的***及电压变动率也小，电压质量容量得到控制和保证，所以在制造变压器时，必须根据满足设备运行条件来设计阻抗电压，且应尽量小一些。LENZEBFK458-08E*USED*ALLENBRADLEY871P-E13GRTSERIESA*USED*LOTOF2SQUARED9080-FB3211R*USED*LOTOF3SQUARED9080-FB1211R*USED*LOTOF2NUMATICS139-136120/60COIL*USED*LOTOF2NUMATICS139-132P120/60COIL*USED*LOTOF2GENUINESTEARNS6-3-45756-09COIL*USED*LOTOF3DECCO11-148230/60COIL*USED*LOTOF2DECCO9-11115/60COIL*USED*LOTOF2DECC139-187P230/60*USED*ALLENBRADLEY872C-D2NP8-E2SER.C*USED*LOTOF2DECCO9-2464M-056COIL*USED*LOTOF2N109C220/240/60COIL*USED*LOTOF2NAMCOEB201-72163220/60COIL*USED*LOTOF4BELLOWSK593-025COIL120/60*USED*VICKERSSV3-16-0-0-115A?PVALVE115V*USED*LOTOF2BOURNS3590S-A63-102L*USED*LOTOF2KLOCKNERMOELLERFAZNC2*USED*KOINOKH-3011SELECTORSWITCH*USED*INTERMATICMODELET715CELECTRONICS7DAYTIMERSWITCH...TELEMECANIQUEXS1M30PA370D*USED*NUMATICS152JJ4000*USED*SONACMODEL11LPROXIMITYSENSOR*USED*WIE***NN12-60368*NEWINABOX*SQUARED9001-B-35CONTROLSTATION*USED*REMKEINDUSTRIES107A0120A1CABLETRERICETEMPERATURECONTROLLER52-1925*NICE*GASTAH103F*USED*LENZE2002*USED*EAGLESIGNALHP510A601*USED*GECIRCUITBOARD44B398262-001/4?4A397857-G01*USED*GECIRCUITBOARD44B398285-001/4?4A397879-G01*USED*ALLENBRADLEY871C-E4B12SERIESB*USED*TRELECTRONICCE100SENCODER*USED*WINTERSP9270-300PSI/KPAGAUGE*NEWINABOX*SPRECHER+SCHUHCA7-9-10*NEWINTHEBOX*POTTER&BRUMFIELDKRPA-14AG-120*NEWINBOX*EDWA***CONTACTOR46E*NEWINBOX*TELEMECANIQUELC1D09480V*USED*LOTOF2MICROSWITCHBZ-2***5551-A2LIMITSWITCH*USED...CUTLERHAMMERE50DN1SER.A1OPERATINGHEAD*USED*GEV-LINED32CIRCUITBREAKER2POLE*USED*MAC45A-SA1-DFBJ-4J?DVALVE*USED*F&TFKG27UF125V*USED*TELEMACANIQUEXS1N18NA340*USED*PHOENIXCONTACTFLKM-D25-SUB/S*USED*GEMULIMITSWITCHTYP.1251240986*NEWOUTOFABOX*AEGDEP210/AS-BDEP-?210*USED*AEGDEP210*USED*WESTINGHOUSEFB3020(CRACK)*USED*PDIPDCA-ADJ*USED*I***9952-0500/T12-A?110*USED*MODUTECT2S-DMA-001-NL*USED*TURN-ACTD-32ACTUATOR*USED*NUMATROLPE4-0001*USED*MERLINGERINC60N-6A*USED*GOYENRCA20T000*USED*BAUMERELECTRICIFR122420*USED****CMGQL50-100PNEUMATICCYLINDER*NEWINABOX*AERO-MOTIVECO.SR902*NEWOUTOFABOX*POTTERELECTRICVSR-F8INCH*NEWINABOX*HONEYWELLDC200E-1-00R-10?0000-0*USED*TURCKBI5-G18-AZ3X-B1?33150MM*USED*JOSLYNCLARK5U4*USED*APOLLOCF8M1500WOG2INCHES*USED*STI44513-0070*USED*DWYER1823-0-1-S*USED*GENERALELECTRICCR120C04002AA*USED*TDKRAX5-10K*USED*FAELS.A.3-32720*USED*LOTOF2DAYTONPLUG-INRELAY5X824*USED*LOTOF2OPTO22DA5I/OMODULE*USED*MACVALVE92B-ACH-000-DU-?DDAP-1DM*USED*CUTLER-HAMMERCONTACTSTARTERKIT3POLESERIESA1CE15...MICROSWITCHLSC1ELIMITSWITCH*USED*KEYENCEEM-005*USED*FENWALL120F*USED*PPOE0-3461-012-010*USED*ELESTAOLS120*USED*ELTROMATCS500-POB-FBBOARD*USED*ELTROMATCX-CS500BOARD*USED*ELTROMATCS-02.2-AUTO-INBOARD(ASPICTURED)*USED*HEIDENHAINLS513LINEARSCALE*USED*THESINGERCOMPANY05088-CU9109550?5*USED*PECOMODULARCONTROLMODELMMC3006-6695*USED*ITWRANSBURG74735*NICE*ADAPTECTRANTORT160SCSI*USED*HALDEXBARNES8498*USED*DAIICHIKEIKITHERMOMETER0-100DEGREESC*USED*EUCHNERTZ1LE024BHA*USED*C1903ABBS283K63A*USED*TRANSAMERICADEL***ALSWITCHFLOW44718*USED*DAYTONRELAY1A488N24VDC*USED*SOLA/HEVI-DUTYGLQ-01-200*NEWOUTOFABOX*IFMEFECTORE18026*USED*NSDCORP.SYSTEMCARDSW-VS2-04E-03*USED*ALLENBRADLEY42MTB-5000SERIESB*NEWINABOX*LIQUIDCONTROLSM7-41800-3*USED*A&DELECTRONICBALANCEER-182A*USED*POSTGLOVERCZ353179RESISTOR*USED*RIDGEWOODUSA45CP012THERMATOOLTRIGGER*USED*WORCESTERCONTROLS2039SNPNEUMATICACTUATOR(ASPICTUR...)
