Fault Analysis ntawm Primary Winding ntawm Tam sim no Transformer
Aug 05, 2022| Internal txhaum ntawm tam sim no transformer khoom
Txhawm rau txheeb xyuas qhov laj thawj ntawm qhov yuam kev ntawm tam sim no transformer, ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog yuav tau xav txog seb tam sim no transformer nws tus kheej yog faulty. Tom qab tus thawj tam sim no transformer, yog hais tias lub rwb thaiv tsev puas thaum lub sij hawm thauj los yog installation, ib feem ntawm lub peev xwm yuav sib txuas lus nrog cov roj conservator, thiab tam sim no cov kev taw qhia ntawm lub tam sim no transformer kuj yuav hloov raws li. Cov thawj tam sim no yog thim rov qab raws li cov roj conservator ntawm tam sim no transformer, thiab qee qhov tam sim no tsis yog raws li qhov thib ob winding ntawm cov roj tank nyob rau hauv lub tam sim no transformer, thiaj li hais tias lub excitation ntawm lub hauv paus tam sim no ntawm lub transformer tam sim no. theem nrab tam sim no hloov. Ua rau muaj qhov sib txawv loj ntawm qhov yuam kev. Thaum qhov kev ua txhaum no tshwm sim, tib neeg ua qhov kev ntsuam xyuas ntawm qhov tam sim no transformer ntawm qhov chaw, thiab nws pom tias qhov yuam kev tsim los ntawm txhua qhov kev sib tw thib ob tsis ua raws li cov kev cai ntawm cov khoom siv tshwj xeeb, thiab qhov yuam kev muaj teeb meem loj. Raws li kev txheeb cais ntawm cov kws tshawb fawb, cov xwm txheej zoo li no kuj tsis tshua muaj, yog li nws yooj yim los txheeb xyuas qhov ua txhaum thaum kuaj xyuas qhov txhaum.
Lub tsheb npav tseem ceeb txuas tsis ua hauj lwm thaum lub sij hawm sim teb
Thaum qhov kev ntsuam xyuas ntawm qhov tam sim no transformer yog nqa tawm, lub busbar txuas nrog lub davhlau ya nyob twg ntawm lub tam sim no transformer, qhov kev ncua deb ntawm lub sab busbar thiab cov roj conservator yog me me, los yog ob tug overlapped, los yog txawm lub bolts nyob rau hauv lub sab busbar thiab roj conservator txuas nrog. Lap ua ke yuav ua rau cov thawj tam sim no sib cais thaum nws txuas nrog cov roj conservator. Qhov teeb meem no tam sim ntawd hloov qhov excitation ntawm thawj tam sim no mus rau theem nrab tam sim no, thiab qhov ua yuam kev tshwm sim kuj yuav loj me ntsis. Piv txwv li, tam sim no transformer khoom tsim los ntawm ib tug tej chaw tsim tshuaj paus, tus maub los yuav raug ntsuas qhov ntau zaus: los ntawm 0.7Hz mus rau 350MHz, tam sim no ntau yam ntawm: 20mA mus rau 500kA random tam sim no cov ntaub ntawv teeb liab, nrog rau qhov tseeb ntsuas ntawm Cov ntaub ntawv hloov pauv hloov pauv, mem tes tam sim no, ib leeg mem tes, sinusoidal, xov tooj cua zaus thiab ntau yam kev sib tw hauv Circuit Court cov ntaub ntawv, thiab xyuas kom meej tias qhov kev kuaj pom tseeb tsis tsawg dua 1 feem pua. Tom qab tau txais cov khoom, tus neeg siv thawj zaug ua ib qho kev sim ntawm lub tam sim no transformer, thiab pom tias sab busbar thiab lub qaum ntsia liaj qhov rooj ntawm cov roj conservator tau overlapped, thiab tam sim no yuam kev yog tshwm sim los ntawm qhov no. Tom qab ntawd, nyob rau hauv cov kev taw qhia tshwj xeeb ntawm cov chaw tsim khoom tam sim no transformer, cov neeg siv khoom tau kho lub puab tsaig ntawm sab busbar thiab ntsia liaj qhov rooj. Tom qab lwm qhov kev sim, qhov yuam kev ntawm tam sim no transformer mus txog tus qauv. Tom qab kwv yees, vim li cas qhov kev ua yuam kev loj ntawm cov neeg siv khoom yuav tsum yog qhov teeb meem ntawm qhov tam sim no transformer nyob rau hauv ib puag ncig kev thauj mus los.
