Transformer rwb thaiv tsev yog dab tsi?
Thaum nws los txog rau lub zog hluav taws xob, peb xav txog cov txiaj ntsig kev tsim khoom loj thiab kev yooj yim ntawm lub neej nws coj, tab sis kuj tsis tuaj yeem pab tab sis ua tib zoo saib xyuas nws lub hwj chim thiab kev nyab xeeb, tom qab tag nrho, nws muaj lub npe ntawm "hluav taws xob tiger". Hauv kev siv hluav taws xob niaj hnub hloov pauv, "kev rwb thaiv tsev" muaj feem xyuam rau nws txoj kev nyab xeeb.
Basic tswvyim
Rwb thaiv tsev, yog ib lo lus ntawm lub cev, hais txog kev siv cov khoom siv tsis zoo rau kev sib cais lossis qhwv lub cev them nyiaj, txhawm rau tiv thaiv kev tiv thaiv hluav taws xob tiv thaiv kev nyab xeeb. Lub rwb thaiv tsev ntawm lub hwj chim transformer yog los tiv thaiv qhov tshwm sim ntawm tam sim no to thiab tawg, thiab kom ntseeg tau cov hluav taws xob kev nyab xeeb thiab kev ntseeg siab ntawm lub transformer. Nws muaj feem xyuam rau cov rwb thaiv tsev ntawm transformer windings, hlau cores thiab lwm yam khoom siv nrog hauv av, nruab nrab ntawm cov theem sib txawv windings, thiab ntawm qhov sib txawv voltage.
Hom rwb thaiv tsev
Lub rwb thaiv tsev ntawm lub zog transformer muab faib ua tiav rwb thaiv tsev thiab qib rwb thaiv tsev. Ua kom tiav rwb thaiv tsev yog qhov twg tag nrho cov winding yog insulated rau tib theem thiab yog haum rau me me transformers thiab tsis muaj peev xwm siv. Lub npe hu ua graded rwb thaiv tsev (tseem hu ua semi- rwb thaiv tsev), uas yog, lub ntsiab rwb thaiv tsev ntawm lub transformer winding nyob ze ntawm lub hauv paus ntsiab lus yog qis dua lub ntsiab rwb thaiv tsev ntawm lub input sab. Transformers rau 35KV thiab qis dua cov chav kawm voltage yog tag nrho cov rwb thaiv tsev. Cov qib insulated transformer yog tsuas yog siv nyob rau hauv high tam sim no grounding system ntawm 110kv thiab sab sauv voltage theem fais fab. Piv nrog rau tag nrho cov rwb thaiv tsev, graded rwb thaiv tsev tuaj yeem txo qhov luaj li cas ntawm cov rwb thaiv tsev sab hauv, kom qhov loj ntawm tag nrho cov transformer raug txo, tus nqi yog txo, thiab nws yog ntau yig. Txawm li cas los xij, nws kuj muaj qee qhov tsis zoo, xws li hais txog kev nyab xeeb, nws tsis zoo li kev rwb thaiv tsev tag nrho.
Insulating qauv
Transformer rwb thaiv tsev los ntawm sab hauv thiab sab nraud ntawm qhov pom, tuaj yeem muab faib ua cov rwb thaiv tsev sab nraud thiab sab hauv.
Internal rwb thaiv tsev hais txog cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob sib txawv hauv lub tank transformer, feem ntau suav nrog cov rwb thaiv tsev winding, txhuas thiab kais-changer rwb thaiv tsev. Cov rwb thaiv tsev no yeej tsis cuam tshuam los ntawm cov xwm txheej sab nraud xws li huab cua, muaj kuab paug, ya raws, cov khoom txawv teb chaws, thiab lwm yam. Cov rwb thaiv tsev sab hauv tau muab faib ua cov rwb thaiv tsev tseem ceeb thiab cov rwb thaiv tsev ntev. Kev rwb thaiv tsev tseem ceeb yog hais txog kev rwb thaiv tsev ntawm windings rau hauv av, nruab nrab ntawm theem thiab nruab nrab ntawm windings ntawm tib theem thiab txawv voltage theem. Qhov no yog qhov tseem ceeb tshaj plaws ntawm cov rwb thaiv tsev nyob rau hauv lub transformer, uas ncaj qha cuam tshuam rau kev ua hauj lwm kev ntseeg siab thiab cov khoom nqi ntawm lub transformer.
Sab nrauv rwb thaiv tsev hais txog lub tsho rwb thaiv tsev thiab cua rwb thaiv tsev sab nraum lub transformer roj tank, nrog rau lub tes tsho rwb thaiv tsev nws tus kheej thiab lub rwb thaiv tsev ntawm lub tes tsho rwb thaiv tsev thiab cov huab cua sib txawv ntawm lub rwb thaiv tsev raj thiab hauv av. Kev ruaj ntseg ntawm cov rwb thaiv tsev sab nraud yog cuam tshuam zoo heev los ntawm ib puag ncig, tab sis nws muaj peev xwm rov ua tau zoo.
Cov txheej txheem rwb thaiv tsev thiab cov khoom siv
Lub rwb thaiv tsev ntawm lub hwj chim transformer feem ntau yog siv roj-immersed rwb thaiv tsev, rwb thaiv tsev qhuav, roj rwb thaiv tsev thiab lwm txoj kev. Roj-immersed rwb thaiv tsev yog tsuas yog siv rau roj-immersed transformers, uas muaj peev xwm xyuas kom meej tias lub transformer ua hauj lwm ib txwm nyob rau hauv high voltage tej yam kev mob, thiab muaj zoo noo noo-pov thawj, txias, poob siab thiab arc extinguishing kev ua tau zoo. Qhuav rwb thaiv tsev thiab roj rwb thaiv tsev yog tsuas yog siv nyob rau hauv qhuav transformers, qhuav rwb thaiv tsev muaj qhov zoo ntawm tsis yooj yim rau damp, tsis yooj yim rau hluav taws, yooj yim rau tu, tab sis tsis haum rau high voltage ib puag ncig. Gas rwb thaiv tsev muaj tsawg dielectric tas li thiab zoo arc extinguishing kev ua tau zoo, tab sis nws yog kim thiab nyuaj rau tshem tawm roj nyob rau hauv lub sij hawm.
Ntawm cov khoom siv insulating, muaj cov khoom siv thiab cov khoom ua kua. Cov khoom siv xws li cov ntawv insulating, corrugated insulating ntawv, Denison ntawv, Nomex ntawv, thiab lwm yam, cov ntaub ntawv no muaj thermal stability thiab ya raws. Cov ntaub ntawv ua kua, xws li cov roj insulating, yuav tsum tau kuaj thiab tu kom zoo.
Cov ntaub ntawv rwb thaiv tsev kuj tseem tuaj yeem muab faib raws li qib cua sov, cov qib sib xws yog A, E, B, F, H tsib, txhua qib muaj qhov sib piv txwv kev ua haujlwm kub. Qhov siab tshaj plaws qhov ntsuas kub rau Class A rwb thaiv tsev yog 105 degrees. Qhov siab tshaj plaws kub tso cai rau Class E rwb thaiv tsev yog 120 degrees. Qhov siab tshaj plaws kub tso cai rau Class B rwb thaiv tsev yog 130 degrees. Qhov siab tshaj plaws qhov ntsuas kub rau Class F rwb thaiv tsev yog 155 degrees. Qhov siab tshaj plaws qhov kub ntawm chav kawm H rwb thaiv tsev yog 180 degrees.
Rwb thaiv tsev teeb meem
Rwb thaiv tsev laus
Transformer rwb thaiv tsev aging yog ib tug complex thiab gradual txheej txheem, nws yog hais txog cov rwb thaiv tsev cov ntaub ntawv nyob rau hauv lub transformer, nyob rau hauv lub sij hawm ntev kev khiav hauj lwm txheej txheem, cuam tshuam los ntawm ntau yam, maj mam poob lub qub mechanical zog thiab hluav taws xob rwb thaiv tsev zog. Transformer rwb thaiv tsev laus feem ntau muaj cov hauv qab no yog vim li cas: tsis zoo noo noo rwb thaiv tsev, tshuaj corrosion, lub sij hawm ntev overloading, transformer sib koom tsis ua hauj lwm, hluav taws xob laus, siab laus thiab thiaj li nyob. Nyob rau hauv teb rau kev laus ntawm transformer rwb thaiv tsev, rwb thaiv tsev tiv thaiv kev ntsuam xyuas, dielectric poob qhov zoo tshaj plaws kuaj, huv si thiab qhuav, tsis tu ncua roj hloov tshuaj ntsuam xyuas, thiab txij nkawm ntawm cua txias system yuav tsum tau nqa tawm tsis tu ncua.
Rwb thaiv tsev damp
Cov rwb thaiv tsev ya raws ntawm lub hwj chim transformer yog ib qho yooj yim ua rau lub transformer inter-txheej los yog inter-tig luv luv Circuit Court, uas ua rau kev puas tsuaj rau lub hwj chim system. Lub rwb thaiv tsev ntawm lub zog hloov hluav taws xob cuam tshuam los ntawm cov dej noo feem ntau yog vim li cas hauv qab no: (1) Lub rwb thaiv tsev yog cuam tshuam los ntawm qhov tsis zoo ntawm lub transformer (2) Lub rwb thaiv tsev yog cuam tshuam los ntawm qhov teeb meem zoo ntawm lub transformer (3) rwb thaiv tsev. cuam tshuam los ntawm cov dej noo thaum lub sij hawm kev thauj mus los ntawm lub transformer (4) installation thiab txij nkawm ntawm lub transformer tshwm sim los ntawm lub rwb thaiv tsev yog cuam tshuam los ntawm kev laus ntawm lub hwj chim transformer. Yog li ntawd, nyob rau hauv qhov kev pom ntawm cov teeb meem ntawm cov rwb thaiv tsev ntawm cov hluav taws xob rwb thaiv tsev, cov khoom siv hluav taws xob hloov hluav taws xob yuav tsum tau kho tsis tu ncua, xws li cov dej noo nyob rau hauv lub sij hawm los hloov, thaum lub sij hawm kev thauj mus los, kev tu kom tsis txhob ya raws, roj stray, xyuam xim rau cov txheej txheem kev khiav hauj lwm thaum lub sij hawm. siv, kom tsis txhob rwb thaiv tsev ya raws los ntawm kev ua haujlwm tsis raug.
