Dab tsi yog Cov Lus Qhia Tseem Ceeb rau 150 kVA Roj -Immered Fais Fab Transformer?

Yog koj150 kVA roj- raus fais fab transformerlub pob txha txhim khu kev qha ntawm koj txoj haujlwm?Zoo li txhua yam tseem ceeb ntawm cov cuab yeej siv, nws cov lus dab neeg25-40 xyoo kev pab cuam lub neejtsis siv neeg - nws tau txais los ntawm kev mob siab rau, kev saib xyuas zoo.

 

Raws li tus thawj cojfais fab transformer manufacturers, GNEE tau pom tias yuav ua li cas cov txheej txheem kev saib xyuas yog ib qho tseem ceeb tshaj plaws hauv kev tiv thaiv kev ua tsis tau zoo thiab tsis tau npaj tseg.

 

Phau ntawv qhia tswv yim no qhia txog cov lus qhia tseem ceeb ntawm kev saib xyuas rau koj150 kVA roj-immersed transformer, txav los ntawm cov kev kuaj pom yooj yim mus rau qhov kev kuaj pom zoo tshaj plaws, txhawb nqa koj los tiv thaiv koj lub zog thiab ua kom zoo dua koj cov nqi tag nrho ntawm cov tswv cuab.

 

Lub Philosophy ntawm Transformer Maintenance: Predictive Over Reactive

 

Reactive txij nkawm- kho tej yam tom qab lawv tawg- yog ib lub tswv yim kim thiab pheej hmoo rau cov cuab tam fais fab. Rau ib150kVA transformer muaj, lub hom phiaj yogkev kwv yees thiab kev tiv thaiv kev saib xyuas.

• Kev Tiv Thaiv Kev Tiv Thaiv (Lub Sijhawm -raws li):Teem sijhawm ua haujlwm (xws li kev tshuaj xyuas txhua xyoo, kev sim roj 5 xyoos) txhawm rau tiv thaiv kev ua tsis tiav.
• Predictive Maintenance (Txoj Cai-Raws li):Siv cov ntaub ntawv (xws li kev tshuaj ntsuam roj, qhov kub thiab txias) los kwv yees thiab daws teeb meemua ntejlawv ua rau muaj kev puas tsuaj.

Ib qho kev sib xyaw ntawm ob qho tib si, tsom rau cov ntsuas kev noj qab haus huv hauv qab no, yuav ua kom muaj kev ntseeg siab tshaj plaws.

 

Core Maintenance Area 1: Insulating Oil - Txoj Kev Ntsuas Ntshav Qab Zib

Cov roj insulating yog ob qho tib si txias nruab nrab thiab dielectric insulator. Nws tus mob yog qhov qhia txog kev noj qab haus huv tseem ceeb tshaj plaws.

 

A. Kev kuaj thiab kuaj roj tsis tu ncua

 

Ntau zaus: Txhua xyoorau cov ntsuas tseem ceeb; txhua2-3 xyoosrau standard faib units. Tom qab ua txhaum loj heev los yog xob laim, ua ib qho qauv tam sim ntawd.

 

Cov Kev Ntsuas Tseem Ceeb & Yam Lawv Qhia:

• Dielectric Breakdown Voltage (BDV):Ntsuas insulating lub zog. Ib qho poob qhia tias muaj dej noo los yog cov kab mob sib kis.Action Limit:<30 kV(tus qauv rau 150 kVA units).
• Cov ntsiab lus dej (ppm):Moisture accelerates rwb thaiv tsev laus.Action Limit:<25 ppmrau cov chav kaw kaw.
• Acidity (Neutralization Number):Nce raws li roj thiab ntawv rwb thaiv tsev hnub nyoog vim oxidation.Action Limit: >0.5 mg KOH/gqhia txog kev laus.
• Dissolved Gas Analysis (DGA):Cov cuab yeej twv ua ntej muaj zog tshaj plaws. Txheeb xyuas cov pa roj (H₂, CH₄, C₂H₂, thiab lwm yam) tsim los ntawm kev ua txhaum sab hauv (arcing, overheating, ib nrab tawm).
• Ntsiab Gas Saib: Acetylene (C₂H₂).Kev tshwm sim feem ntau qhiasab hauv arcing- mob hnyav yuav tsum tau tshawb xyuas tam sim.

 

B. Oil Preservation System Xyuas

 

Conservator & Breather:Tshawb xyuas covsilica gel breather. Yog hais tias qhov qhia tias silica gel yogntau tshaj 75% liab, nws yog saturated nrog noo noo thiab yuav tsum tau hloov tam sim ntawd. Xyuas kom meej tias cov roj theem nyob rau hauv lub conservator nyob rau hauv lub cim ntau yam (rau cov roj kub tam sim no).

 

Core Maintenance Area 2: Hluav taws xob & Mechanical Integrity Checks

 

A. Kev kuaj pom thiab ntsuas cua sov

Ntau zaus:Peb lub hlis twg los yog ob-ib xyoos.

 

Yuav kuaj li cas:

• Roj Leaks:Tshawb xyuas lub tank welds, gaskets (nyob ib ncig ntawm bushings, radiators), li qub, thiab lub conservator diaphragm rau tej yam tshwm sim ntawm seepage los yog stains.
• Bushings:Tshawb xyuas cov kab nrib pleb (porcelain), nrhiav cov cim, kev sib kis, lossis cov kaus mom tawg. Xyuas kom cov kev sib txuas yog nruj thiab tsis muaj corrosion.
• Radiators & Cooling Fins:Xyuas kom lawv huv si thiab tsis muaj kev cuam tshuam los ntawm cov nroj tsuag, av, lossis noog zes. Thaiv radiators drastic txo cov cua txias efficiency.
• Xim & Corrosion:Tshawb xyuas lub tank sab nrauv rau cov pob xeb lossis xim degradation, tshwj xeeb tshaj yog nyob rau hauv welds thiab lub hauv paus.
• Thermal duab:Siv lub koob yees duab infrared txhua xyoo los luam theej duabbushings, cable txuas, thiab tank nto. Hotspots qhia txog kev sib txuas xoob, cov theem dhau los, lossis cov khoom siv hluav taws xob sab hauv.

 

B. Kev Ntsuas Hluav Taws Xob (feem ntau thaum lub sijhawm teem sijhawm)

• Winding Resistance Test:Tshawb xyuas cov kev sib txuas xoob, cov hlua tawg, lossis cov teeb meem tiv tauj hauv cov kais hloov pauv.
• Rwb thaiv tsev Resistance (Megger) Test:Ntsuas qhov kev noj qab haus huv ntawm cov rwb thaiv tsev (roj + ntawv) ntawm windings thiab rau hauv av. Cov txiaj ntsig tau zoo nyob rau lub sijhawm muaj txiaj ntsig ntau dua li kev nyeem ib zaug.
• Turns Ratio Test:Txheeb xyuas qhov tseeb qhov hloov pauv hloov hluav taws xob thiab tuaj yeem pom qhov luv luv nyob rau hauv windings.

 

Core Maintenance Area 3: Protective Devices & Accessories

 

Cov cuab yeej no yog koj thawj kab ntawm kev tiv thaiv; lawv yuav tsum ua haujlwm.

 

• Cov cuab yeej siv siab:Visually soj ntsuam tus chij taw qhia. Xyuas kom lub qhov cua tsis thaiv.
• Buchholz Relay:Rau cov chav nyob li ntawd, txheeb xyuas lub tswb thiab lub voj voog ncig ua haujlwm tau ua haujlwm thaum kuaj. Tshawb xyuas lub iav qhov muag kom pom cov pa roj ntau ntxiv (qhov pom tseeb ntawm qhov ua txhaum sab hauv).
• Winding Temperature Indicator (WTI) & Oil Temperature Indicator (OTI):Tshawb xyuas calibration txhua xyoo los ntawm kev sib piv nrog ib tus pas ntsuas kub sib txawv. Xyuas kom lub tswb thiab cov neeg mus ncig ua si ua haujlwm kom raug.
• Tswj txee:Tshawb xyuas cov dej noo, corrosion, lossis kab tsuag kab tsuag. Xyuas kom cov cua sov (yog tias tam sim no) ua haujlwm kom tsis txhob muaj qhov hws.
