Yuav kuaj roj transformer ntau npaum li cas?

Qhov ntsuas zaus rau cov roj transformer nyob ntawmNtau ntau yam, tab sis cov qauv kev lag luam (zoo li IEEE C57 {{}} 106, thiab ASTM D923) muab cov lus qhia dav dav raws qib voltage, kev thuam, thiab muaj hnub nyoog, thiab thauj khoom. Ntawm no yog qhov tawg:

Qhov tseem ceeb cuam tshuam rau kev soj ntsuam zaus:

Kev Ntsuas Qib:

Highest voltage:Ntau dua voltage hloov yog qhov tseem ceeb dua thiab xav tau ntau tshaj sim .

Kev txaus siab:

Cov chav nyob tseem ceeb:Transformers Qhov tseem ceeb rau cov kev sib xyaw ruaj khov, cov txheej txheem muaj cov txheej txheem loj, lossis tsis muaj kev hloov dua tshiab yuav tsum tau kuaj ntau dua .

Cov koog tsawg dua:Faib cov kev hloov pauv lossis cov uas muaj kev rov ua dua tshiab yuav raug sim tsawg dua .

Lub hnub nyoog thiab mob:

Cov hloov pauv tshiab (1st xyoo):Ntau zaus kuaj (e {. g}}}}}}, tom qab 1 hlis) mus ntes cov teeb meem thaum pib.

Cov hloov pauv qub / keeb kwm ntawm cov teeb meem:Ntau zaus kuaj xyuas vim muaj kev pheej hmoo siab tshaj .

Keeb kwm ruaj khov:Chav nyob nrog cov txiaj ntsig tau zoo nyob tsis tu ncua yuav tsim nyog tau kuaj zaus tsawg .

Chaw thau khoom:

Cov khoom hnyav thauj / siv cov khoom siv ntau dhau:Tsim ntau cov cua sov thiab kev ntxhov siab, xav tau kev saib xyuas ntau dua .

Ib puag ncig:

Harsh qhov chaw:Cov av noo, kev ua qias tuaj, lossis qhov kawg kub tau ua rau muaj kev txwv tsis pub qeeb dua, yuav tsum tau kuaj xyuas ntau zaus.

Pom zoo zaus (raws li Ieee / iEC qhia):

High voltage kis hloov pauv (ntau dua los yog sib npaug rau 115 kV lossis cov khoom tseem ceeb):

Yam tsawg kawg:Ib xyoos ib zaug .

Raug / Zoo Tshaj Plaws:Txhua 6 lub hlis (ib nrab xyoo) .

Heev tseemceeb / ntxhov siab:Ib hlis twg los sis tseem ntau dua (e {. g {}}}}, tom qab paub ntau dua lossis ua txhaum).

Nruab nrab hluav taws xob faib / Hloov hloov pauv (hauv qab 115 kV):

Yam tsawg kawg:Txhua 2-4 {.

Raug / Zoo Tshaj Plaws:Txhua xyoo lossis txhua 2 xyoo .

Cov Kev Muaj Kev Lag Luam Tseem Ceeb:Feem ntau ib xyoos .

Tsawg dua cov hluav taws xob muab hluav taws xob qis:

Yam tsawg kawg:Txhua 4-8 {.

Raug:Txhua 4-6} xyoo, lossis raws li kev tshuaj xyuas cov kev pabcuam .

Feem ntau sim tsawg feem ntau tsuas yog muaj teeb meem uas xav tias .

Kev kuaj ntshav tseem ceeb ntxiv (sim tam sim ntawd):

Tom qab kev txhaum lossis loj tshaj plaws dhau los:Los ntsuas kev puas tsuaj thiab yaj roj av .

Ua ntej thiab tom qab kev saib xyuas loj / de-energization:Ua kom cov roj mob hnyav yog tsim nyog ua ntej rov ua kom .

Tam sim ntawd hloov hauv bushing / siab relay nyeem:Qhia tias cov teeb meem sab hauv .

Pom teeb meem:Cloabiness, txawv xim, lossis muaj zog tsw ntxhiab tsw lwj .

Qhov hloov pauv tseem ceeb hauv kev ua haujlwm:Kev txhawb nqa siab, kev hloov ib puag ncig .

Cov kev ntsuam xyuas uas nquag ua:

Kev kuaj ib txwm (feem ntau):

Dielectric puas voltage (DBV):Kev ntsuas insulating muaj zog .

Acidity (NeutRalization tus naj npawb):Qhia oxidation dectradation .

Interfacial nro (Ift):Pom Soluble Ncaws Pob Muaj Zog Polar Txhaum / Oxidation Khoom .

Xim:Qhov taw qhia yooj yim ntawm kev laus / kis .

Kev kuaj pom:Clarity, hais, dej dawb .

Cov ntsiab lus dej (feem ib lab - PPM):Tseem ceeb rau rwb thaiv tsev intwb muaj zog .

Deatolved roj tsom (DGA): Tseem ceebrau kev kuaj pom sab hauv (arcing, overheating, partial paug) {}}} Ntau yog tias cov teeb meem tshwm sim .

Ntxiv cov kev ntsuam xyuas (raws li xav tau):

Lub Hwjchim Muaj Zog / Dissipation Qhov

Kev Ntsuam Xyuas Furan (Cov Ntawv Laus)

Inhibitor cov ntsiab lus

Oxidation Ruaj

PCB Soj ntsuam

Corrosive Sulphur

Cov kev coj ua zoo tshaj plaws:

Tsim kom muaj ib lub hauv paus:Sim cov roj tshiab thiab tam sim ntawd tom qab txhaws cov tshiab / kho hloov pauv hloov tshiab .

Kev Tshawb Fawb:Sib piv cov txiaj ntsig dhau sijhawm - tiam sis feem ntau yog tshaj tawm tshaj li ib qho ntaub ntawv taw tes .

Ua raws cov lus qhia:Txheeb xyuas phau ntawv hloov pauv .

Ua raws li cov cai hauv zos:Cov khoom siv thiab kev lag luam feem ntau muaj cov qauv tshwj xeeb .

Siv cov ntaub ntawv labs:Xyuas kom ntsuas qhov tseeb thiab kev ntseeg tau .

Xav txog kev kuaj mob ntawm chaw:Yooj yim kev ntsuam xyuas zoo li DBV, noo noo, xim tuaj yeem ua tau ntawm-chaw rau cov tshev nyiaj ceev ntawm tag nrho cov kev ntsuas ntsuas ntsuas ntsuas ntsuas

Hauv cov ntsiab lus:

HV transformers tseem ceeb: Txhua xyoo mus rau ib nrab-ib xyoos(DGA feem ntau txhua xyoo, kev sim ua niaj hnub) .

MV Faib / Tseem Ceeb Industrial: Txhua xyoo rau txhua 2 xyoos.

LV faib: Txhua 4-6 xyoo.

Ib txwm sim sim sai tom qab kev ua txhaum, loj dua, lossis cov cim ntawm teeb meem .

Qhov tseem ceeb tshaj plaws yog los ntawm zaus zaus ntawm kev hloov pauv cov ntaub ntawv, thiab cov keeb kwm ntsuas kev ntsuas, thiab tsuas yog ib qho kev ntsuas keeb kwm kev sib tw.Kev ua kom muaj zog ntawm kev kho mob yog qhov zoo tagnrho .
