ABBEI812F3BDH000021R1变压器是变换交流电压、电流和阻抗的器件，当初级线圈中通有交流电变压器原理图流时，铁芯（或磁芯）中便产生交流磁通，使次级线圈中感应出电压（或电流）。变压器由铁芯（或磁芯）和线圈组成，线圈有两个或两个以上的绕组，其中接电源的绕组叫初级线圈，其余的绕组叫次级线圈。在发电机中，不管是线圈运动通过磁场或磁场运动通过固定线圈，均能在线圈中感应电势，此两种情况，磁通的值均不变，但与线圈相交链的磁通数量却有变动，这是互感应的原理。变压器就是一种利用电磁互感应，变换电压，电流和阻抗的器件。在额定功率时，变压器的输出功率和输入功率的比值，叫做变压器的效率，即：η=(P2÷P1)x100%式中，η为变压器的效率；P1为输入功率，P2为输出功率。大功率高压配电变压器当变压器的输出功率P2等于输入功率P1时，效率η等于100%，变压器将不产生任何损耗。但实际上这种变压器是没有的。变压器传输电能时总要产生损耗，这种损耗主要有铜损和铁损。铜损是指变压器线圈电阻所引起的损耗.当电流通过线圈电阻发热时，一部分电能就转变为热能而损耗。由于线圈一般都由带绝缘的铜线缠绕而成，因此称为铜损。变压器的铁损包括两个方面：一是磁滞损耗，当交流电流通过变压器时，通过变压器硅钢片的磁力线其方向和大小随之变化，使得硅钢片内部分子相互摩擦，放出热能，从而损耗了一部分电能，这便是磁滞损耗。另一是涡流损耗，当变压器工作时，铁芯中有磁力线穿过，在与磁力线垂直的平面上就会产生感应电流，由于此电流自成闭合回路形成环流，且成旋涡状，故称为涡流。涡流的存在使铁芯发热，消耗能量，这种损耗称为涡流损耗。变压器的效率与变压器的功率等级有密切关系，通常功率越大，损耗与输出功率就越小，效率也就越高。反之，功率越小，效率也就越低。140NOE77101140XBP01000140XTS00200DKCXX.3-040-7GPIB-USB-HSUSB-6251MAS51A030-503-02DSQC352APCI-6289PCI-67041756-IF16IC200MDL640CIIMCL01IIMCP01IIMKM01IIMLM01IMASI23DSQC6433HAC024488-001/01XRNP-12/2-50-1;12KV,IN=2A,IA=50KA,E=194MM,D=25MMJAMSC-B2743VJAMSC-B2914JRMSP-PS60ADV-1711P/N:AD525AAZX63MWM-25-02XSERVOVML25PCI-6289PCI-6703PCI-670424VBG5925BSH1002P01A2A1C31224G011C31233G041C31234G015X00119G011756-L1M2FHT116SE7090-0XX84-0FJ06XV1821-0AH10MDV60A0220-503-4-00NY24W-KUSB-XW2Z-200S-VACS800-01-0006-3+E205+P901ACS800-07-0205-3ACS800-07-0260-3M-2348-1036SE7090-0XX84-0FJ0ATV12H075M26DD1600-0BA16DD1610-0AH66DD1661-0AD0VT2-7SBDM-48006RA2432-6DV62-0XCS-E7333SPARC-5/64-32-1102711E-T10C156SC6612-4AA008520-OPS16ES7972-OCB20-0XAOM062-LE-511EENRZ-AU40-20CHC-443FSP235-60GTRU-32-8RDC1-23504E37063708E9566-8109766-2109766-610DFV180M4/TFADC5423-3VMIVME-5565-010000VMIVME-5565-110000SDCS-CON-4-COAT-ROHSSDCS-PIN-48-COATSDCS-PIN-51-COATSDCS-POW-4-COAT20BD052A0AYNAEC02711P-RW1MVME162PA-252SE2150LVT-HNC100-1-23W-08-0-0185615-013101330133513401IPC5000/5600/5000V/5600CSX-16CPU-40B/16CPU-40B/4GT1275-VNBA1746-OB16DT100L4KR120P1746-P4ABE7CPA03CR2L-30140M-D8E-C161756-CNBR/E1756-CP31756-IB321756-L55M131756-L611756-PB751784-PCIC1786-RPA1786-RPF1786-RPFM1794-PS1380190-220-01R6DD1601-0AE01746-P4JPDC-C035KINETIX600015A2094-BM02-MKINETIX600016A2094-BM01-MKINETIX60009A2094-BC01-MO1-MMPL-B310P-SJ22AAMPL-B430P-SJ22AAMPL-B4530F-SJ24AAFBM202FBM203FBM212FBM217FBM223FBM232T-1401PM803FTDS320CP60BUG622-28-54-B-006SL3040-0MA00-0AA13HAB8101-16/10AMADSQC6043HAC129281-1FBM242140ACI03000140ACI04000140CPS21400140CPU65150140DDI35300140DDO35300140DDO84300140ERT85410Z140NOE77101140XBP01000140XTS00200CIMR-HB4A0024代CIMR-G7A4P5SGMG-20A2AB1785-LT/BIC697BEM731140***O02000FX1N-40MRFXIS-30MR1326AB-B430E-S2L1326AB-B515G-S2K5L1326AB-B530E-S2L140CPS214003BSC760015R1C500-PS222E1X00024H013A99132G025X00105G01VT8000SPAJ140CPS24457***09FBM41CP0902XA带接线端子3BSE001037R13BSE007836R1A20B-1006-0472/05BA20B-2901-076557***09METEOR2/MC-1CFN351-16-295KH36MNA445X830100372DAI01DAO01HD22010-3HD22020-36EW1861-3AB6EW1861-3ABLXD63***0PRM3PA17KN32TMP2203LM1X00024H013A99132G025X00105G011784-KTXKRC1LXD63***0RL-3200S1756-A101756-DNB1756-ENBT1756-IB321756-L611756-OB321756-PA751756-TBCH01984-2518-00021734-IB81734-IE8C1734-OB8EEP3640-1436-7-56BCBUG622-28-54-B-009C500PS222EDSQC6043HAC12928-1E-Z32Z326EP1436-2BA00IC693ACC310IC693CBL300IC693CHS393IC693PWR330IC694TBB032XVME-674TAUACC-24E2A16903A140ACI04000140CPS21400140CPU65150140DDI35300140DDO35300140ERT85410Z140NOE77101140XBP01000140XCP51000140XTS00200E4410-601701756-A171756-A71756-CNBR1756-ENBT1756-IB321756-IF81756-L611756-N21756-OB321756-PA721756-TBCH1757-SRC11757-SRM1784-CF641786-TPS1786-XTXBTF024110XBTMEN08MC-41771-P2APA2800VA24H1500UDX51051756-L616ES7214-2BD23-0XB8M100DC1786-RPA1756-BA11756-PA721794-OW850SCCM140CPS11420140CPU11303140CPU65150140CRP93100CPS-420FJZNC-NIF01B-1JZRCR-NPP01B-1JZRCR-NTU01D-1SGDR-AXA01ATSX3708001TSXDMZ28DRPC832-001-T6***6671-1CB00-0AX26ES7315-2EH14-0AB06ES7321-1BL00-0AA06ES7322-1BL00-0AA06ES7332-5HF00-0AB06ES7355-2SH00-0AE06ES7390-1AJ30-0AA06ES7392-1AJ00-0AA06ES7392-1AM00-0AA06ES7953-8LL11-0AA06ES7972-0CB20-0XA0升级6***6642-0BA01-1AX16NH9720-3AA00IC693CPU311IC693MDL645IC693MDL9401756-IB161769-L35EEDS-305IC693CPU374-GVSGDM-20ADASGMGH-20ACA61PC832-001-T6ES7216-2AD23-OXB86ES7231-OHC22-OXA86ES7307-1EA01-OAAO6ES7315-2AH14-OABO6ES7331-7KF02-OABO6ES7365-0BA01-OAAO6ES7392-1AJ00-0AA06ES7953-8LJ30-0AA0EM140AF4-053HNE00442-1/06220316IN/16A06B-0826-B100VE4001S2T2B4VE4002S1T2B5VE4003S2B1VE4003S5B1VE4003S6B1MHD093C-058-NP1-BN140ACI03000140CPS11420140CPU43412A140DAI75300140DAO84210140NOE771011769-IQ161769-IR61769-L311769-OW81769-PB46ES7331-1KF02-0AB0MHF-D100LRER-JG-7200DSC14PT6SE6440-2UD32-2DB1S263-D16PTQ-PDPMV1P0973HA5X00105G14ACS800-01-0006-3+P901ACS800-01-0120-3+P901+D150KPS-600/20-ESC600/20-ESC1756-DNBAK-BX56M6SE7031-8TF601336F-B125-AN-ENPS-DA0125-043(S)PS-M06D12S5-NJ1L(S6SE7037-OEK60IC3645LXCD1GPD515C-B0341757-SRMAM-SA85-000AM-SA85-002OKYM6W22N-2302-1-F04AA3503E3604E3700A6EP13363BA003540E37063708E9566-8109765-6109766-2101606-XLE240EA06B-6087-H115A06B-6089-H203A06B-6102-H222#H520A860-2020-T301YB560103-CDDSQC236G140ACI03000140ARI03010140CPS12420140DAI75300140DAO85300SX6-DRIVECI830)
