Vim li cas hloov kev hloov ua? To taub cov suab nrov hloov pauv
Jun 20, 2025
Tso lus
Thaum lub sijhawm ua haujlwm ib txwm, pauv hloov pauv ib lub suab uas lom zem heev, feem ntau tshwm sim los ntawm cov hlau leakintrostrict - Qhov kev co hauv kev sib nqus flux. Ib qho uas niaj hnub ua yog suav tias yog ib txwm muaj. Txawm li cas los xij, yog tias lub suab transformer ua tsis xwm yeem lossis txawv txawv, nws yuav qhia qhov txhaum. Los ntawm kev txheeb xyuas hom thiab cov yam ntxwv ntawm cov suab no, cov neeg ua haujlwm tuaj yeem txheeb xyuas cov teeb meem muaj peev xwm thiab teb kom sai. Qhov no ua rau lub suab txawv txav hauv Transformer system muaj cov khoom siv kuaj mob uas muaj nqis.

Suav hais tias ib txwm yog hais tias luv - nyob thiab tsis muaj lwm yam txawv txav
Cov ntsiab cai tseem ceeb
Cov ntsiab cai tseem ceeb ntawm kev kho lub suab tshuaj Transformer
1. Kev ntsuam xyuas theem pib
Lub Suab Ua Haujlwm: Thaum lub sijhawm ua haujlwm ib txwm, tus hloov pauv hluav taws xob tau tshwm sim khov kho, tsis zoo siab lub suab.
LUS CEEB TOOM: Ib qho kev hloov pauv ntawm cov qauv suab, xws li thaum buzzing, nyem, popping, lossis sib tsoo, yuav tsum tau kho raws li lub cim ceeb toom. Cov khoom siv hloov no feem ntau qhia txog cov teeb meem xws li cov teeb meem tseem ceeb, rwb thaiv tsev ib feem tawm, lossis kev ntxhov siab ib nrab. Kev qhia thaum ntxov ntawm cov suab thaum ntxov tuaj yeem tiv thaiv kev ua tsis tiav ntau.
2. Hla -} siv tau
Kev kuaj mob Transformer transformer kom raug kom muaj kev ntsuas sib xyaw los ntawm ntau qhov chaw:
Cov yam ntxwv suab:
Hom: Puas yog nws yog ib qho, hiss, buzz, crackle, lossis bang?
Ntev: Nruam, sib quas ntus, lossis offset sai?
Cov lus sib dhos: cov qauv sib txawv lossis kev coj ua tshwj xeeb?
Ntsuas Kev Nyeem:
Cia li spikes lossis dauv hauv voltage thiab tam sim no yuav sib haum nrog arcing sab hauv lossis luv luv.
Kev kub siab nyeem ntawv kub tuaj yeem piav cov cim kev nkag siab lossis txias ua tsis tiav.
Kev kuaj xyuas roj (rau roj {-}}} Cov chav nyob):
Xim: Roj tsaus nti tuaj yeem qhia kev laus lossis paug.
Theem: Ib qib roj nce tuaj yeem qhia tau ib qho xau.
Qhov kub thiab txias: kev kub siab ntau feem ntau cuam tshuam nrog kev ua txhaum sab hauv.
Ib puag ncig qhov tseeb:
Sab nraud qhov chaw zoo li cov av noo, hmoov av, lossis pom corona tso zis tuaj yeem ua rau nrov nrov lossis ua rau muaj lub tswb cuav.
Los nag hnyav, cua, lossis xob laim yuav ua rau lub suab nrov thauj mus los tsis cuam tshuam rau sab hauv.
Cov xwm txheej txheej txheem:
Kev hloov pauv ntawm kev siv thauj khoom, voltage hloov, lossis daim phiaj xwm phiaj xwm yuav ua rau muaj kev ntxhov siab lossis hluav taws xob kev kos npe.
Txiav txim siab seb tus hloov pauv tsis ntev los no tau ntsib ib qho kev hloov pauv, kev ua yuam kev, lossis load kauj ruam - nce / down.
Kev tiv thaiv kev ua haujlwm relay:
Txhua txoj haujlwm ntawm kev tiv thaiv sib txawv, Buchholz Relay, lossis qhov kub thiab txias nyob rau hauv suab nrov nrog lub suab tsis txaus ntseeg yog qhov ntsuas tau loj ntawm kev ua txhaum sab hauv.
3. Liab chij - Thaum twg yuav tau ua tam sim ntawd
Cov suab nrov txawv txav nrog cov tsos mob hauv qab no qhia tau tias muaj kev txhaum loj sab hauv thiab lav ntawv tam sim ntawd thiab kev tshuaj xyuas:
Cov tawg tawg, npau npau, lossis suab nrov:
Tuaj yeem qhia sab hauv arcing, rwb thaiv tsev tawg, lossis roj ntau dua vim yog overheating lossis luv luv.
Sawv siab ceev ceev hauv cov roj kub lossis qib o tuaj txog:
Qhia txog cov cua sov sab nraud lossis siab tsim -}}} Up, tejzaum teb tsis tau muaj arcing lossis winding ua tsis tau.
Kev ua kom muaj kev pab tiv thaiv kev sib txuas lossis lub tswb foob:
Xws li Buchholz relay tripping, roj kev rov ua kom zoo, lossis cov kev sib cav sib txawv ntawm kev ua tsis tiav xws li interning- Tig luv luv, Tub Ntxhais Hluas Hluav Taws Xob, lossis roj zuj zus.
Yog tias ib qho ntawm cov mob no tau pom, tus hloov pauv yuav tsum tau coj tawm ntawm kev pabcuam tam sim ntawd kom tiv thaiv kev puas tsuaj lossis hluav taws.
