GE现货销售IS200VAICH1CIS215UCVFH2A.IS215UCVFH2A1、电流信号检测电路1）模拟信号放大电路U12、U13（TL084C四运放IC）内部部分电路，对电流互感器输出的电流信号进行初步（反相）放大后，经过电平位移，处理为MCU可以接受的电压信号，送入MCU的79、80、81引脚。这是三路模拟电压信号。2）电流信号基准电路由MCU的86脚（或为+5V供电引脚）的+5V，经U14反相处理为-9.7V的电流准电压，再送入U12、U13组成的反相器（与输入信号构成加法器）电路，经衰减形成2.4V的电流基准（表征为零电流水平）信号，输入MCU。3）过载/接地故障信号形成电路电流互感器输出的采样电流信号，经***级放大后，同时输入由D5~D7组成三相全波整流电路，得到IUVW全电流信号，经U14进一步处理为“单向电流信号”，送入后级窗口电压比较器电路，过载发生时，据运行状态的不同，报出过载或接地故障。2、直流电压信号检测电路1）从开关变压器的-15V工作绕组，反向整流取出开关管饱和期间（相关于一次高压绕组接入DC530V）产生的感生电压（象征着DC530V的高低），由R46、R45分压衰减为3.9V采样信号，经U13电压跟随器处理后，输入至MCU的83脚。此为一路模拟电压信号，用于直流回路电压显示。2）D19整流输出的电压检测信号，同时与ZD3构成的基准电压信号相比较，当大于基准电压时，光耦PC8导通，将过电压信号故障信号输入MCU的55脚。3、模拟温度检测信号模块温度变化由2k热敏电阻取出，与R27、R61分压后，由U13电压跟随后，输入至MCU的83脚。4、熔断器状态检测电路在熔断器完好时，光耦PC6的输入端电压为0V，不能形成输入侧发光二极管的电流通路。当熔断器熔断后，FUSE1两端出现巨大的电压差，经R30限流，光耦PC6输出端4脚由+5V变为0V，将熔断器的故障信号，输入至MCU的75脚。同时，以上各路故障信号（熔断器故障信号除外），同时还输入F21（全称为SN74F21）与门电路，处理后，送入MCU的52脚。该机型的故障检测电路，在一图中已经全了。也作了***简要的原理分析，希望对大家有用。DAI01DAO01CIMR-E7U47P5PMES-09A24140DDI84100A06B-6087-H130EVR1166FC5210-0DF20-0AA0***6FC5210-0DF20-0AA0现货ATV71HC11N4ATV71HC13N4ATV71HC16N4ATV71HD75N4ZMVI56-MCM6GK7343-1EX11-0XE06GK7443-1EX11-0XE0DAI01DAO01E4809-045-152AHA-655-4-200P0916FHIC697BEM731E5515CSGM-02A3NT12SGM-04A3NT121394-SJT10-C-RL140ACI03000140CRP93200140DAI75300140DRA84000DIS-248/10140CPU43412IC693PW***1S6RA7018-6DS22-0MDX60A0075-5A3-4-00214-1BD23-0XB86ES7216-2BD23-0XB86ES7235-0KD22-0XA8JAPMC-CM2300JAPMC-CM2302-EECPP60-01CS513DSAO120ADSDI110DSDO115DSDP170DSSR122DSTD150APM511VTC52031C030-503-4-00O-56921-6061C31194G01（配1C31197G01）1756-IF6I1746-P21756-BA1电池1756-L61SST-PFB-CLX-RLLCM311768-L439101-1303DIN3380400BIC693BEM331IC693CPU364IC693CPU374IC693PWR331A06B-6079-H101A06B-6079-H104A06B-6079-H206GP10E9ST34040B1PC10E1ST34001A16SN1227-2ED10-0HA01756-IT6IIC697BEM731IC697CMM742IC697CPX935IC697MDL241IC697MDL341IC697PWR711VACIII-D6SPINDLEDRIVEUNITCPS-150FGJR5251400***0207DC91M10-MFGIC200MDL640IC200MDL640CAGP3500-T1-AF6ES7953-8LP20-0AA0F1-130DR6FC5103-0AD20-0AA0F1-130DRFCW504-02-X101-C6DL3100-8AC6SC9811-4BF53C200H-PS221RM5G-42003HAC023195-001/031756-A131756-CNB/E1756-ENBT/A1756-IB16I1756-IF161756-IM16I1756-IR6I1756-L611756-OF81756-OW16IA03B-0807-C011A03B-0807-C104#DA03B-0807-C152#DA03B-0807-C154A03B-0807-C161#DA06B-6077-H106A06B-6077-H111A06B-6079-H101A06B-6079-H104A06B-6079-H206A06B-6102-H211#H520A06B-6114-H207A06B-6130-H002BR***00PHCBR***000000PC-E984-685PTQ-PDPMV11768-L43622A11TAE1510PC/AT5170CIMR-MTIII-7.5KPCI-MXI-2MDS60A-0015-5A3-4-00LC-EF-10GE-4P140ACI04000MA-0185-100XL20CHXL20CH6ES59517-LD21IC670MDL241M***7-12-300-RPTQ-PDPMV11784-PKTXLTE120.6KVA0608750040170AAI14000140DDI35300XC5010CXF502XF521AXF522AXF523AXF524A8250-596VAD-ME-I-3/8-35533BKDC-16IC698CHS009IC698CRE030IC698PSA100IC698RMX0161756-DNB1756-IB161756-IF6CIS1756-OB16D1756-OF46GK1151-2AA00SAC-M1450-400BKDR-161747-L5511756-L61140CPU671606FC5250-6DY30-5AH06GK1551-2AA00C79459-A1890-A106ES5390-0UA11140DDI85300140DDO35300CCD8D615103HAC6367-1CIMR-J7AA20P2DSX-***00-V2IC693ALG392IC694ALG392IC694ALG221IC694MDL660IC694MDL754IC695CPU310RSIC695PSD040F140DDI85300140DDO35300CM400YKP081000000GG含4个IPM02P0902XAP0972AJTSXCPP110140CPU671606GK7342-5DA03-0XE0CI541V13BSE014666R16ES7416-3FR05-0AB0FRN22F1S-4C140ACI03000140ARI03010140CRA93200140CRP93200140DDI85300140DDO35300140NOE77101AB7000-BMKD041B-144-KG1-KNRCGROUPMP2000NC1ETNC1L-RS2NC1S-1NC1X1604-WNC1Y16T05P5-13DM455.60-2E30004380A****************************************************************1756-CNBR/D1756-DNB1756-ENBT1756-TBCH1756-TBNHIC697CPX935IC697PWR711A06B-0267-B605MDX60A0075-5A3-4-003RT1015-1AB01ED63B050FXD63B150MTG0050J6SC6110-0EH03KPS-60/20-ESCKSD1-08KSD1-32KSD1-48CT-602-KX1756-CNB1756-ENBT1756-L611756-PA721784-CF641786-RPA1786-RPFM1794-ACN151794-PS32711P-T6C20DMVI46-MNET6DR1900-51756-A71756-BA11756-CNB1756-CNBR1756L55M131756-PA721757-SRM1786-TPY1794-ACNR151794-IB321794-IE81794-OB32P1794-OF4I1794-PS31794-TB31794-TB32ACS600I/O板NICO-01RAP10-MSW1I/F-3ROD270-18000MK9906N.82OSE-A57/2MVI69-MCM1606-XL240EA20B-3300-0281SKBD200150OPTIFLUX4100C1SBP260020R100107CR41MDV60A0300-503-4-00140DAI75300T1F-08AD-16DD1681-0CA2DSQC313恒睿电子科技有限公司2711P-RDT15CBZE6-2RN194IC693CPU323LE-30CTAT1F-08AD-13HAC025338-002INICT03ADDCP-921310JACP-317120JACP-317800JACP-921900JEPMC-10220JEPMC-EX200JEPMC-MB200JEPMC-MB210JEPMC-MC200JEPMC-MC2209602-0205SN39379DDCP-921310JACP-317120JACP-317800JACP-921900JEPMC-10220JEPMC-EX200型号BZE6-2RN194IC693CPU323LE-30CTAT1F-08AD-13HAC025338-002INICT03ADDCP-921310JACP-317120JACP-317800JACP-921900JEPMC-10220JEPMC-EX200JEPMC-MB200JEPMC-MB210JEPMC-MC200JEPMC-MC2209602-0205SN39379DDCP-921310JACP-317120JACP-317800JACP-921900JEPMC-10220JEPMC-EX200JEPMC-MB200JEPMC-MB210JEPMC-MC200JEPMC-MC220E8403AVXIMAINFRAME9905-792XVME-653GB-23/USBGD-773/ADB5331AE6C-AB4B6DD1601-0AH06DD1681-0EA16DD1681-0FG06DD1688-0AE26DL3100-8AC1769-0B32)
