Kev Tiv Thaiv Kev Tiv Thaiv rau Roj -Filled Transformers
Roj- cov roj hloov pauv yog nyob ntawm cov roj insulating rau lub zog dielectric, cua sov dissipation, thiab kev tiv thaiv kev tiv thaiv sab hauv, tab sis kev laus, noo noo, oxidation, thiab hluav taws xob kev ntxhov siab maj mam txo qis roj kev ua haujlwm thiab txo qis kev ntseeg siab ntawm transformer.
Huazheng's Transformer Oil Test Equipment Solution muab cov cuab yeej ua tiav thiab ua tau zoo rau kev saib xyuas mob, kuaj xyuas qhov tsis raug, thiab kev tswj xyuas lub neej, ua kom cov khoom siv hluav taws xob, cov neeg siv khoom lag luam, EPC cov neeg cog lus, thiab cov chaw muab kev pab tu kom raug, cov ntaub ntawv - tsav kev txiav txim siab tu.
Kev lag luam keeb kwm
Roj- puv transformers ua haujlwm tsis tu ncua nyob rau hauv high voltage, siab kub, thiab ntev kev pab cuam mus txog. Insulating roj tsis tsuas yog ua hauj lwm raws li ib tug dielectric nruab nrab tab sis kuj ua raws li ib tug rhiab qhov taw qhia ntawm internal transformer tej yam kev mob.
Cov kev lag luam tseem ceeb muaj xws li:
- Hloov los ntawm kev kho kom raug mus rau kev tiv thaiv thiab kev kwv yees txij nkawm
- Ua kom pom tseeb ntawm cov cuab yeej cuab tam lub neej optimization
- Kev nruj dua raws li IEC, IEEE, thiab cov qauv kev saib xyuas hluav taws xob
- Kev thov loj zuj zus rau ntawm -site, kev tshawb nrhiav roj sai kom txo qis sijhawm
Kev kuaj roj tau dhau los ua cov cuab yeej kuaj xyuas tseem ceeb los ntsuas qhov kev laus ntawm rwb thaiv tsev, thermal kev nyuaj siab, dej paug paug, thiab kev txhim kho hluav taws xob.
Cov yam ntxwv ntawm kev sim roj hauv kev lag luam Transformer
Roj raws li Diagnostic Medium
Transformer roj qhia txog cov xwm txheej sab hauv kom raug ntau dua li kev ntsuas sab nraud. Cov kev hloov me me hauv cov roj chemistry lossis cov ntsiab lus roj feem ntau qhia thaum ntxov- theem ua ntej ntev ua ntej hluav taws xob tsis ua haujlwm.
Multi-Parameter Dependence
Tsis muaj ib qho roj parameter tuaj yeem sawv cev rau kev noj qab haus huv transformer. Kev tiv thaiv zoo yuav tsum muaj kev ntsuam xyuas ua ke ntawm cov txiaj ntsig ntawm dielectric, tshuaj lom neeg, thiab roj.
rhiab heev rau Environmental Factors
Moisture ingress, oxygen exposure, thiab kub variations ncaj qha cuam tshuam cov roj zog, yuav tsum tau siab -precision thiab rov ntsuas dua.
Ntev -Tshaj Tawm Txog Lub Sij Hawm
Kev ntsuam xyuas roj yog qhov zoo tshaj plaws thaum cov txiaj ntsig tau taug qab lub sijhawm, ua cov ntaub ntawv sib xws, rov ua dua, thiab khaws cov digital tseem ceeb.
Risks & Challenges thiab Mitigation Strategies
Kev tso tawm ib nrab, qis -zog arcing, thiab overheating hauv cheeb tsam tuaj yeem txhim kho nyob rau hauv transformer windings lossis ntawv rwb thaiv tsev. Cov kev ua txhaum no feem ntau nyob twj ywm zais thiab tsis tuaj yeem tshawb pom los ntawm kev tshuaj xyuas qhov muag lossis kev ntsuas sab nraud.
- Dissolved Gas Analysis (DGA):Nthuav cov pa phem (H₂, CO, C₂H₂, CH₄) tsim thaum lub sij hawm hluav taws xob lossis thermal stress.
- Trend-Raws li kev soj ntsuam:Tsis tu ncua sampling thiab automated qauv tsom xam tso cai rau thaum ntxov qhia txog cov pa txawv txav ua ntej ib tug txhaum escalates.
- Integrated Oil Testing:Kev sib xyaw ua ke BDV, noo noo, acidity, thiab IFT ntsuas ua kom muaj kev pom zoo ntawm kev hloov pauv kev noj qab haus huv.
Thermal stress, oxidation, thiab ya raws cov kab mob maj mam degrade roj thiab rwb thaiv tsev ntawv. Kev laus txo cov dielectric zog thiab ua rau muaj kev pheej hmoo ntawm kev tawg thaum lub sijhawm ua haujlwm.
Periodic Dielectric Strength Test (BDV): Ua kom cov roj muaj peev xwm ua kom muaj rwb thaiv tsev txaus.
Acidity (TAN) & Interfacial Tension (IFT) Kev Saib Xyuas: Tracks roj oxidation thiab sludge tsim.
Kev Tiv Thaiv Roj Regeneration: Thaum kuaj tau tshaj qhov pib, ua kom pom, degassing, los yog hloov roj kom muaj kev ruaj ntseg ntawm rwb thaiv tsev.
Cov dej nkag los ntawm cov ntsaws ruaj ruaj, nqus pa, los yog condensation tuaj yeem txo qhov muaj zog dielectric, txhawb kev tso tawm ib nrab, thiab ua kom lub rwb thaiv tsev laus.
- Siab -Kev ntsuas qhov ntsuas dej noo:Cov cuab yeej muaj peev xwm ntawm ppm- qib raug (tsawg dua lossis sib npaug li 1 ppm) rau ob qho tib si yaj thiab dej dawb.
- Sealed Sampling txheej txheem: Txo cov dej noo ib puag ncig thaum lub sij hawm sau roj.
- Trend Analysis thiab Alarming:Txheeb xyuas qhov nce noo noo thiab ua kom muaj kev saib xyuas thaum ntxov lossis roj kom qhuav.
Tsawg- cov cuab yeej siv tau zoo, cov txheej txheem tsis sib xws, lossis cov neeg ua haujlwm yuam kev tuaj yeem tsim qhov tsis ruaj khov lossis tsis yog - rov nyeem dua, ua rau kev txiav txim siab saib xyuas tsis raug.
- High-Cov cuab yeej muaj tseeb: BDV testers, ntsuas dej noo, thiab DGA cov cuab yeej nrog cov zis ruaj khov thiab rov ua kom raug.
- Automated Test Sequences: Txo kev ua haujlwm ntawm phau ntawv thiab ua cov txheej txheem txheem.
- Calibration thiab Verification:Tsis tu ncua calibration tiv thaiv thoob ntiaj teb cov qauv (IEC 60156, IEC 60567, IEEE C57) kom ntseeg tau cov ntaub ntawv.
