ABBDO8103BSE008510R11、互感器的异常分析1）一、二次接头接触不良：一次接头不良引起接头处过热（安装质量差或螺丝松动），二次接头不良将易造成CT二次开路或PT二次失压（端子排螺丝不紧或者是在剥线头做小圈时铜线严重受伤）。2）互感器突然声音异常：正常声音类似于“嗡嗡”声但很细微。如发现正常声音特大或有放电声，就可能是绝缘局部击穿、螺丝松动或者CT二次开路。3）气味：正常时无气味，如有异味或焦糊味，则可能是内部铁芯或线圈过热。2、电压互感器的异常处理1）PT熔断器熔断或二次回路断线当中央信号屏发出“TV电压回路断线”的预告信号，同时光字牌亮，警铃响。检查电压表可发现：未熔断相电压指示不变，熔断相指示降低或指示为零，与该相有关的线电压指示为相电压值，与此电压无关的表记指示正常。处理：a、退出PT所带保护与自动装置，防止保护误动作。b、检查PT二次熔断器是否熔断。c、如PT二次回路正常，则应检查一次熔断器是否熔断。2）PT高压熔断器熔断原因分析a、电力系统发生单相间歇性电弧接地。b、电力系统产生铁磁谐振。c、PT本身内部出现单相接地或相间短路故障d、PT二次侧发生短路而二次侧熔断器未熔断，也可能造成高压熔断器熔断。3）PT其他事故处理当PT发生下列严重事故时，应立即停用，并向上级汇报。注意在停用PT时严禁用取高压熔断器的办法，应使用PT本身的隔离开关使PT退出运行。a、PT一次熔断器连续熔断。b、PT漏油、漏胶、瓷套管破碎、外部放电。c、PT着火、冒烟、有糊焦味。3、电流互感器的异常处理1)电流互感器二次开路的处理运行中的CT,当发出噪音或怪音,电流型仪表指示摆动或为零时,则说明此CT二次可能开路。开路后的CT,其二次侧会感应出危险的高电压，危及设备和人身的安全，此时运行人员应做如下处理：a、在靠近CT最近的端子排上将其二次回路短接，在短接时一定要穿绝缘靴，戴绝缘手套和带绝缘把手的工具，在监护人监护下开展工作。b、若短路后，开路现象仍未消除，则可能是互感器本身接线端子或内部开路，此时应立即报告调度，将该CT退出运行后方可进行修理。其它事故处理：当CT发现下列故障时，应立即汇报上级，并切断电源进行处理。a、内部发出异味或冒烟、着火；b、内部有放电现象，声音异常或引线与外壳间有火花放电现象；c、主绝缘发生击穿，造成单相接地故障，d、充油式CT漏油、漏胶。ParkerSERVAX-M0200-MParkerSV-MDriveP100-MParkerCOMPAX-M0200-MParkerNMD20BParkerNMD10BParkerNMD10FestoDGPL32350PPV​ABKFGKSVFestoDGPL25530PPV​AKFBFestoCPXAB8KLFestoSLTE-16-80-G04NetterPKL1705NBeckerDT4.40KMontalvoRP-3000-ceFestoDGPL25400PPV​AKFBSMCSS5Y3-45S0-16B-​M-QSMCMVV5Q11-12C4FUO​-X689-QSMCVQ1-LOF15SMCVQ1-LOK014SMCSV1-LOK012SMCMVV5Q11-10C4FUO​-X689-QParkerSMHA826003814S2​ID65A7ParkerSMHA826003814S2​ID65A74ParkerSMHA826003814S2​ID65-400SMCVQ1-LOF14ParkerSMH826003814S2I​D65-400ParkerSMH827503814S2I​D65-400SMCSY3-LOJ004SMCSV1-LOK013EckardtPC451-6CN11C51A​-17SMCSY3-LOJ003SMCMRHQ10D-180S-NFestoDGE-25-500-SP-K​F-GK-SVFestoDNCKE-40-500-PP​V-AFestoDNC-50-730-PPV-​A-KPSMCAC30-LOK007FestoSLT-25-100-PA170580FestoFENG-80-50-KF34251SMCMVV5Q11-10C4FUOSMCMXS16-100RFestoSLG-12-400-YSR-​A187855FestoDGPL-32-360-PPV​-A-KF-BSCHUNKPHE1004030007898SMCEMGQM40-125Bilz032-200-1000-1FSMCAC50-LNP106DE-STA-CO-Pneum​atik-Kraftzylin​derK400-70-6-1BEKOSORBOEWAMAT20SCHUNKPZN100-2FestoSLT-16-50-A-CC-​BFestoFENG-50-100-KFSMCMHW2-20DSMCVQ1-LOK013FESTOHE-D-MidiHerion24750020800FestoCPV-10-GE-CO-8FestoDFO-25-330-PPV-​ASMCMXS16-20RFestoDGPL-8-200-PAKF​BFestoDRQD-16-180-PPV​J-A-AL-FWSMCAC30-LOK007FestoFEC-FC34-DOSFestoDGP-40-600-PPVARoemheld1545-519FestoMPAL-VI569926FestoDGP-18-650-PPV-​A-BSMCEZM103HF-K5LO-E​55CL-QFestoDRQD-12-90-J60-​A-FW-SD32FestoSLT-25-100-PAFestoDRQD-20-180-PPV​J-A-AL-FW-Z1FestoDGPL-8-200-PAKF​B161975FestoCPV10-GE-MP-8FestoCPX-FB13195740FestoDSR-40-180-P13467FestoDSM-40-270-P-FW157661SMCZX100-K15LOZ-E5​5CN-QFesto8025355Festo542268FESTOMFH52D3FR​C151711FestoDNU10040PPVAS2SMCMHR2-10RSMCMGPL12-50SMCECDRQBW20-180CFestoFENG-63-100-KFSMCZM101HF-K5LZ-QSMCMHR2-10RFestoCPV-10-GE-CO2-8FestoCPV-10-GE-FB-8-​CPIFestoDNC-40-202-PPV-​A-KPMankenberg6231130TA-EFestoVADMI-70SMCMDSUB20-90SFestoDPZ-25-10P-A-KF162096FestoDZH-50-200-PPV-​A14070FestoDGC-8-250-KF-YS​RW-A530906Fischer4195BRiegler350612FestoDFM-32-40-P-A-G​F170857Rexroth5218106240SMCCDY1S10H-100SCHMALZSCPM10NOARexrothRTC-BVRTC-DA-025-0650​-BVParkerPN475265WFestoJMFH51210166SCHMALZ10060200049FestoFENG3250KF34493SMCZX100K15LOZF​QFestoFENG-50-125-KF34489FESTOMFH-5/3G-3/8-B19707FESTOMFH-5/3G-D-3-S-​C151034SMCSYJ3-LQQ048FESTOMFH53GD3C151873Bosch0822010689FestoHGPM-12-EZ-G9197570FestoHGPM-12-EZ-G6197568NUPRO6L-LD8-DDXXFestoCP-FB13-E174337FESTOMFH-5/2-D-3-FR-​C151711FestoADVUL-63-46-P-A156207FestoDNC-40-50-PPV-A163339FestoDNC-40-40-PPV-A163338FestoDFM-25-50-P-A-K​F170926Barksdale41-115941102FestoCPV10-GE-ASI-4E​4A-Z170537GEMÜ9415000ZF05NS11​1SMCZSE40-C6-62LSMCEZM103HF-K5LO-E​55CL-QFestoDNC-50-150-PPV163366FestoSLT-6-20-P-A170550FestoDNC-50-160-PPV-​A163375GEMÜ88039725-00NORGREN0883200SMCMGPL20TF-250bürkert00150825Festo33481FestoDSM-16-270-P-FW​-CCbürkert641-4104GEMÜ88039725-00bürkert641-4104SMCAC30-LOH003SMCCDRB1BW10-90SSMCMXPJ6-10SMCEAV3000-F03-5YO​-QFestoDSRL-12-180-P-F​W30654ParkerB103EFestoJMFH-5-1/4-B19789SCHMALZVS-V-A-PNP-S-M810060200070FestoDNC-40-220-PPV-​A163336ParkerXW68PLP-4-4FestoADN-32-250-A-P-​A536267Rexroth5285010640Rexroth0822010663FestoDSRL-10-180-P-F​WSMCCRB1BWU20-270SFestoVSVA-B-B52-ZD-A​1-1T1L539156FestoDNC-32-500-PPV-​AFestoDNC-32-60-PPV-AFestoDFP-32-50-PPV-AFestoDNC-32-50-P-A-S​11SMCKECDQ2WB50-40DMACESC300EUM-9NORGRENR73G-2AK-RMGSMCMS12-30bürkertZPDW0415100​300SMCGVVZS3000-21A-3SMCCRB1BW20-90SFestoDNC-50-200-PPV-​A163376FestoADVU-25-150-P-A156003ACESC300EUM-9FestoPEN-M58625FestoCPA10-M1H-2X3-G​LS173452FestoJMN1H-5/2-D-1-CFestoVSVA-B-M52-MH-A​1-1R5LSMCGVVZS3000-21A-3SMCVH430-F04FestoLF-D-MAXI159614Buschjost8240203.9101.02​400ACE745651ACE730111ACE757718ACE757001SCHUNK0309274Festo175250FestoMFH3187802Bosch0821303053FestoVIGZ-03-4FestoF-3-MS207988FestoCPV10-GE-MP4SAMSON24102211353FestoCPE10-M1CH-5LS-​M7SMCNVS4114-0009DFestoMS6EM112FESTOPEV14B10773EAED620432FestoHEEDMINI24172956ACEGS19200AAK9​276GEMÜ9415000ZF05NS11​1ParkerPB21649-010FestoGRA14B6509SMCSY7420-5LOU-C8F​-QSMCVQ1301N-5-QSMCVQ1201N-5-QSMCEARP3000-F02-X5​08FestoMFH-3-M54450FestoVAD-MZB-M535552SMCVQ1170N-5LO-C4-​QGEMÜ320-1ACEGS-19-200
