Yuav ua li cas rau nruab thiab tswj 150 kVA Roj-immersed Fais fab Transformer?

Lub sijhawm ntev - kev ntseeg siab thiab kev nyab xeeb ntawm a150 kVA roj- raus fais fab transformerraug txiav txim ncaj qha los ntawm qhov zoo ntawm nws cov installation thiab kev nruj ntawm nws cov kev tu tsis tu ncua. Ib qho yooj yim, kauj ruam-los ntawm- kauj ruam mus kom ze tsis yog pom zoo xwb- nws yog qhov tseem ceeb.

 

Cov lus qhia dav dav no qhia txog cov txheej txheem ua haujlwm tiav raukev txhim khokoj transformer kom raug los ntawm ib hnub thiab qhia txog qhov tseem ceebkev saib xyuascov kev coj ua uas yuav tiv thaiv koj cov peev txheej, ua kom lub sijhawm ua haujlwm ntev tshaj plaws, thiab ua kom muaj kev ntseeg siab tau ntau xyoo hauv kev lag luam, kev lag luam, lossis kev siv hluav taws xob.

 

Peb Yog Leej Twg: Koj Tus Tswv Cuab hauv Transformer Lifecycle Management

 

GNEE yog lub chaw tsim khoom tshwj xeeb los xyuas kom meej tias peb cov khoom ua tau zoo nyob hauv thaj chaw. Peb muab ntau tshaj li hardware xwb; peb muab tag nrho lifecycle kev txhawb nqa. Rau txhua tus150 kVA roj- raus fais fab transformerpeb muab, peb xa cov ncauj lus kom ntxaws installation phau ntawv, kab kos duab, thiab siv tau kev pab tswv yim. Peb lub hom phiaj yog los koom tes nrog koj kom ua tiav kev teeb tsa zoo meej thiab tsim kom muaj kev saib xyuas zoo.

 

Theem 1: Ua ntej-Txoj Kev Npaj thiab Kev Npaj Qhov Chaw

 

Kev vam meej pib nrog kev npaj txhij txhua ua ntej lub transformer tuaj txog.

• Xaiv qhov chaw:Xaiv qhov chaw ruaj khov, theem, zoo-drained sab nraum qhov chaw uas muaj kev nyab xeeb tsawg kawg nkaus. Xyuas kom nws ua raws li cov kev cai hauv zos hais txog kev nyob deb ntawm lub tsev, kab vaj tse, thiab cov khoom siv hluav taws xob.
• Foundation & Plinth:Tsim kom muaj lub pob zeb ua kom muaj zog txaus kom dais lub transformer tag nrho qhov hnyav (unit + roj). Lub plinth yuav tsum yog theem thiab suav nrog qhov raug muab tso rau hauv cov ntsia hlau ntsia hlau. Iboil container bund phab ntsa(muaj peev xwm Ntau dua lossis sib npaug li 110% ntawm tag nrho cov roj ntim) yog qhov yuav tsum tau ua nyob rau hauv feem ntau cov cheeb tsam los tiv thaiv ib puag ncig.
• Clearances:Ua kom muaj kev nyab xeeb yam tsawg kawg nkaus rau qhov cua, kev nyab xeeb hluav taws, thiab kev saib xyuas kev nkag tau raws li qhov xav tauIEC 61936: Uathiab cov lej hluav taws xob hauv zos.

 

Theem 2: Kev Txais, Kev Ua Haujlwm, thiab Kev Ua Haujlwm

 

Kev tuav kom zoo tiv thaiv kev puas tsuaj sab hauv uas tuaj yeem ua rau ua tsis tiav ntxov.

 

• Kev tshuaj xyuas thawj zaug:Thaum xa khoom, xyuas seb puas pom kev puas tsuaj rau shipping. Txheeb xyuas qhov tseeb ntawm bushings, gauges, thiab tank welds. Sau cov roj qib pib thiab kev nyeem ntawv siab.
• Safe Lifting: Tsuas yog siv cov lifting lugsntawm lub tank transformer. Siv lub crane uas muaj ntawv pov thawj nrog cov kab sib kis kom tsis txhob muaj kev ntxhov siab ntawm cov radiators lossis bushings. Tsis txhob nqa los ntawm lwm yam khoom.
• Thaum kawg Positioning & Anchoring:Maj mam txo lub transformer mus rau lub plinth. Teem lub hauv paus nrog lub thauj tog rau nkoj bolts thiab ruaj khov siv siab - tensile bolts, xauv lub tshuab ntxhua khaub ncaws, thiab txiv ntseej. Qhov no tiv thaiv kev txav mus los thaum muaj xwm txheej seismic lossis kev ua txhaum cai.

 

Rau cov haujlwm nyuaj, GNEE muajsaib xyuas cov kev pab cuam installationkom ua raws li cov kev coj ua zoo tshaj plaws.

 

Theem 3: Kev sib txuas hluav taws xob, Earthing, thiab Pre-Energization Checks

 

Cov theem tseem ceeb no yuav tsum tau ua los ntawm cov kws tsim nyog siab -voltage electricians.

 

Muab cais nyob ib leeg:Paub meej tias cov khoom siv dej ntws HV yog de-energized, cais, kaw, thiab tagged tawm (LOTO).

 

Kev sib txuas:Ntxuav tag nrho HV thiab LV bushings. Siv cov kab hluav taws xob loj thiab txiav tawm kom zoo. Tighten tag nrho cov txiv ntseej txuas rau cov chaw tsim khoomqhia

 

tus nqi torquesiv lub calibrated torque wrench. torque tsis raug yog qhov ua rau kub kub thiab tsis ua haujlwm.

 

Earthing (Grounding):Txuas lub transformer lub ntsiab lub ntiaj teb terminals mus rau lub site lub grounding electrode system nrog ib tug neeg xyuas pib ntawm txaus cross-section. Qhov no yog qhov tseem ceeb rau kev nyab xeeb thiab kev tiv thaiv kev ua haujlwm.

 

Tswj Kev Ruaj Ntseg:Txuas cov xaim rau kev tiv thaiv cov cuab yeej (Buchholz relay, lub zog nyem, WTI/Oil Temperature Indicator) rau lub tswb / tswj vaj huam sib luag.

 

Ua ntej-Kev Xeem Ua Haujlwm:Ua cov kev xeem tseem ceeb:

• Rwb thaiv tsev Resistance (IR)thiabPolarization Index (PI)ntawm windings.
• Transformer Hloov Ratio (TTR)xeem.
• Winding Resistancentsuas.
• Roj Dielectric zog Test(los ntawm ib qho piv txwv).

 

Tsim kom muaj Kev Txhim Kho Kev Ua Haujlwm Zoo

 

Kev saib xyuas tsis tu ncua yog tus yuam sij rau kev kwv yees ua tau zoo thiab lub neej ntev.

• Kev Tshawb Fawb Txhua Hnub / Lub Limtiam:(Rau qhov chaw muaj neeg ua haujlwm) Kev soj ntsuam pom cov roj xau, suab nrov txawv txav, thiab txheeb xyuas cov roj qib / ntsuas ntsuas kub.
• Kev Tshawb Fawb Txhua Hli / Peb Hlis:Tshawb xyuas silica gel breathers (yog tias haum) rau kev hloov xim; tshawb xyuas thiab sau cov haujlwm ntawm cov khoom siv cua txias; tshawb xyuas corrosion.
• Kev tu txhua xyoo:Qhov no yog qhov tseem ceeb tshaj plaws uas tau teem sijhawm ua haujlwm.
• Oil Sampling thiab Testing:Laboratory tsom xam rauDielectric zog, Moisture Content, Acidity (Neutralization Number), thiab Dissolved Gas Analysis (DGA). DGA yog lub cuab yeej kuaj xyuas muaj zog rau kev kuaj pom qhov tsis raug sab hauv xws li arcing lossis overheating thaum ntxov.
• Kev ntxuav thiab tshuaj xyuas sab nraud:Ntxuav lub tank, radiators, thiab bushings ntawm av thiab khib nyiab. Xyuas tag nrho cov kev sib txuas, bushings, thiab gaskets.
• Kev Xeem Ua Haujlwm:Kev sim ua haujlwm ntawm txhua qhov kev tiv thaiv relays, tswb, thiab cov kiv cua txias (yog tias tsim nyog).
• 5-Xyoo/Ntev Kev Kho Mob:Raws li cov txiaj ntsig kev ntsuas roj thiab keeb kwm kev ua haujlwm, xav txog kev ua ntau yam zoo liroj pom los yog hloov, kev tshuaj xyuas sab hauv (yog tias qhia los ntawm DGA), thiab rov kho cov tub ntxhais / sib koom bolts los ntawm tus kws tshaj lij.

 

Peb phau ntawv qhia rautransformer roj kuaj thiab tsom xammuab kev nkag siab tob rau hauv txoj haujlwm tseem ceeb no.
