ABBBAILEYIMDSI14、NFTP01一、静态测试1、测试整流电路找到变频器内部直流电源的P端和N端，将万用表调到电阻X10档，红表棒接到P，黑表棒分别依到R、S、T，应该有大约几十欧的阻值，且基本平衡。相反将黑表棒接到P端，红表棒依次接到R、S、T，有一个接近于无穷大的阻值。将红表棒接到N端，重复以上步骤，都应得到相同结果。如果有以下结果，可以判定电路已出现异常，A.阻值三相不平衡，可以说明整流桥故障。B.红表棒接P端时，电阻无穷大，可以断定整流桥故障或起动电阻出现故障。2、测试逆变电路将红表棒接到P端,黑表棒分别接U、V、W上，应该有几十欧的阻值，且各相阻值基本相同，反相应该为无穷大。将黑表棒接到N端，重复以上步骤应得到相同结果，否则可确定逆变模块故障二、动态测试在静态测试结果正常以后，才可进行动态测试，即上电试机。在上电前后必须注意以下几点:1、上电之前，须确认输入电压是否有误，将380V电源接入220V级变频器之中会出现炸机（炸电容、压敏电阻、模块等）。2、检查变频器各接播口是否已正确连接,连接是否有松动,连接异常有时可能导致变频器出现故障,严重时会出现炸机等情况。3、上电后检测故障显示内容,并初步断定故障及原因。4、如未显示故障,首先检查参数是否有异常,并将参数复归后,进行空载(不接电机)情况下启动变频器,并测试U、V、W三相输出电压值。如出现缺相、三相不平衡等情况，则模块或驱动板等有故障5、在输出电压正常（无缺相、三相平衡）的情况下，带载测试。测试时，***好是满负载测试。EFECTORIM0055*USED*JOHNSONCONTROLSWHA27A-606R*USED*E&EENGINEERINGEAC-437-F*USED*BANNER***A91L*USED****CNCME125-0100*USED*71255-254P*USED*TELEMECANIQUEXVAC361*USED*LOTOF2MICRO6AS214*USED*ASCO8317A14*USED*ASCO10600075*USED*GEFANUC1C610MDL171B*USED*MICROSWITCHBZE6-RQX2*USED*PARKER850102024VDC*USED*MSCR50480*USED*TELEMECANIQUEXS1N30PA340*USED*COIL15D1G357*USED*EFECTOROF5012*USED*LOTOF2EFECTORIG5841*USED*EFECTORIF5767*USED*TELEMECANIQUEGB2-CB07*USED*ASCOCOIL27-463-11D*USED*EFECTORIM0041*USED*KLOCKNERMOELLERA-PKZ0*USED*TELEMECANIQUEGV2-AU385*USED*LOTOF2MICROSWITCHLS1C*USED*BANNER2LM5-14*USED*LOTOF4GOULD62132*USED*P016074924VDC*USED*BOSCH1837001183115V*USED*EFECTORIF0295*USED*BIMBAMRX*USED*EFECTORE20987*USED*MICROSWITCHFEMLS10*NICE*CLARK7303TYPECPRELAY*USED*COIL1386115V*USED*TELEMECANIQUEXGS-K6204321*USED*ALLENBRADLEY21A244120V*USED*ALLENBRALDLEY160-AA12NSF1*NICE*MAC82A-EA-000-TM-D?AAP-1DASOLENOIDVALVE*USED*ALLENBRADLEY1492-CB2H030SERIESC*USED*POTTER&BRUMFIELDCDB-38-70004*USED*MICROSWITCHPWKBM1241SELECTORSWITCH2POSITIONKEYED...EFECTOROG5125*NEWINABOX*MICROSWITCHFLANGEMOUNTENCLOSURE3PA2*ASIS*77022-002*USED*ROSEMOUNTANALYTICALDIVISION0230A*USED*585-3*USED*306089-01*USED*SUGNODE14002PCBOARD*USED*QUARTECH1KB-1041MTL3041*USED*ACTIONPAK4380-0000*USED*77016161*USED*WACO5460037412*USED*WACO54600374.2*USED*PHD7960-03-1101*USED*FLUOROCABRONMS2-144NCD2*USED*S23DGF6B0*USED*KLOCKNERMOELLERTO-4-6502-65/I*NEW*C0440PB*USED*827759*USED*GOULDNF351H*USED*CIITECHWUV-72DC-1X*USED*ROBINSONENGINEERINGRELAYDRIVER12-1238ELECTROBS1AADLT*USED*MTECORPORATIONRL-01203*USED*WESTINGHOUSEBFLF*USED*BAUMERES34AP5B*USED*PPCSCANNERINTERFACEPB052097*USED*GUARDIANELECTRICA421-064142-01*USED*PARKER01.38THC024.000*USED*REDLIONCONTROLS4610120ROTARYENCODER*NEWOUTOFA...FURNAS14BF32AA*USED*ALLENBRADLEY100-A09NJ3SER.BWITH193-BSB22B24V*USE...HUMPHREYAIRVALVE062E1-3-10-21-3?6*NEWINABOX*GENERALELECTRICGE420P7480VACRECEPT***E&PLUG*...ALLENBRADLEY802M-XJ9NFSERIESB*USED*ALLENBRADLEY802T-HPSER.FLIMITSWITCH*USED****CCH***32-130-K59?WLPNEUMATICCYLINDER*USED****CVQ***401-5DOUBLESOLENOIDVALVEPLUGIN*USED*MACVALVEINC.6321D-211-PM-11?1DASOLENOIDVALVE*USED*DWYER1950P-2-2FEXPLOSIONPROOFPRESSURESWITCH*USED*LOTOF2N109C220/240/60COIL*USED*VICKERSSV3-16-0-0-115A?PVALVE115V*USED*LENZEEMB9341-E*USED*FANUCA20B-0009-0531*USED*BBC05-MA-22SPEEDREGULAT*USED*TRI-TRONICSUCD-AT2PROXIMITYONE-SHOTTIMERDWYER1950-0-2F*FACTORYSEALED*M-SYSTEMSBVS-660VSIGNALTRAN***ITTER*NEWINABOX*LOTOF4PROVISUR19785010000TENSIONSPRINGSET*NEWO...SQUAREDSY/MAX8005-DN-116*USED*LOTOF16HOFFMANF44GUCU-CONNECTOR*NEWINABOX*ALLENAIREA-5-120/60COIL*USED*SQUARED8501-L0-20(CRACK)120V*USED*WOODHEAD5PINCONNECTOR105000A03F060*USED*GE9TF6140*USED*HERRMANNI2DB40/50040*USED*SICK2009317*USED*I***1286-1-A*USED*M1346*USED*ATHENA1000*USED*LOWELL*USED*91380031424V*USED*ALLENBRADLEY595-BLSERIESB*USED*ALLENBRADLEY595-BLSERIESB*USED*FLUIDPRODUCTSCO.12-24-7*USED*EFECTORIF5721*USED*GEC60C*USED*LOTOF3SPECTROLMOD830*USED*CTG27378*USED*STOCKHAM11/2"1258200WP*USED*ALLENBRADLEY709-AODSERIESK*USED*CA-101110V*USED*PNEUMATICPRODUCTS1209748*USED*DAYTON1A331*USED*P&PINDUSTRIES,INC.S4-100A-24*USED*WESTINGHOUSECIRCUITBREAKERFB3020*USED*LOTOF4V8935X*USED*LFE40*USED*PC10-30*USED37646236*USED*CAT6V-6129*USED*PHD10688-2-12*USED*COOPER5000110-5*USED*ACEMCS-1401-0*USED*ARROWF553FIP*USED*CHROMALOX59T/66T3M*USED*920920*USED*DAYTON5X823*USED*CRAMER10078*USED*CRAMER10055*USED*LOTOF2SERIALMCV-220*USED*LOTOF2503013600*USED*RJPM11140A*USED*3001107*USED*GENUINESTERNS634460609COIL460VAC60HZ*USED*HONEYWELL30362481-001*USED*IDECMCM23D-A20*USED*)
