Vim li cas qhov corrosion kuj theem ntawm transformer tso tsheb hlau luam yog li tseem ceeb?

Hauv cov tshuab hluav taws xob, transformers yog cov cuab yeej tseem ceeb rau kev hloov hluav taws xob. Raws li lub plhaub sab nraud uas ncaj qha mus rau ib puag ncig ib puag ncig, lub tank transformer muaj thiab tiv thaiv cov roj thiab cov khoom siv sab hauv, yog li cuam tshuam ncaj qha rau transformer lub neej kev pab cuam thiab kev nyab xeeb ntawm kev ua haujlwm. Yog li ntawd, xaiv qhov tsim nyog tiv thaiv corrosion yog ib qho tseem ceeb ntawm kev tsim transformer.

Kev faib tawm ntawm Transformer Tank Corrosion Resistance Levels

Raws li kev teeb tsa ib puag ncig, kev lag luam feem ntau faib cov qib tiv thaiv corrosion raws li hauv qab no:

Ordinary (C3 Ib puag ncig)

C3 ib puag ncig yog tsim rau qhuav, huv si sab hauv tsev lossis cov chaw nyob deb nroog me me. Tag nrho cov yeeb yaj kiab qhuav tuab rau qib no yog kwv yees li 120-160μm, uas ua tau raws li cov kev cai tiv thaiv corrosion.

Intermediate (C4 Ib puag ncig)

C4 ib puag ncig yog tsim rau cov cheeb tsam kev lag luam hauv nroog, thaj chaw ntug dej hiav txwv uas tsis tshua muaj ntsev tsuag, lossis thaj chaw ntub dej. Nws yuav tsum muaj cov txheej txheem ntau- txheej txheej uas muaj cov epoxy zinc- nplua nuj primer, epoxy micaceous hlau oxide nruab nrab lub tsho, thiab polyurethane topcoat, nrog rau tag nrho cov zaj duab xis qhuav thickness ntawm 160-200μm.

Advanced / Hnyav -Lub Luag Haujlwm (C5 Ib puag ncig)

C5 ib puag ncig yog tsim rau cov cheeb tsam ntug dej hiav txwv uas muaj cov av noo siab thiab cov tshuaj ntsev ntau, cov chaw ua haujlwm tshuaj lom neeg, lossis cov chaw muaj corrosive heev. Cov txheej txheem txheej txheej yuav tsum ua tau raws li cov qauv nruj dua, feem ntau yog siv cov epoxy zinc- nplua nuj primer (zinc cov ntsiab lus Ntau dua lossis sib npaug li 80%), tuab - zaj duab xis epoxy intermediate coat, thiab aliphatic polyurethane lossis fluorocarbon topcoat, nrog rau tag nrho cov yeeb yaj kiab qhuav thickness ntawm 240μm-3.

Qhov tseem ceeb ntawm Transformer Tank Corrosion Protection

1. Tiv thaiv kom tsis txhob tawg thiab ua kom muaj kev nyab xeeb

Yog hais tias lub tank transformer raug corrosion perforation thiab cov roj xau, qhov tshwm sim loj tuaj yeem ua raws li: rwb thaiv tsev degradation vim roj qib poob, hluav taws kub nyhiab los ntawm cov roj sib cuag nrog kub lossis hluav taws xob arcs, thiab ib puag ncig muaj kuab paug ua rau raug nplua.

2. Extending Transformer Service Life

Lub neej tsim ntawm lub tshuab hloov pauv feem ntau yog 20-30 xyoo, thiab lub tank corrosion yog qhov ua rau ua tsis tiav ntxov. High-kev tiv thaiv corrosion zoo tswj lub tank cov txheej txheem kev ncaj ncees thoob plaws hauv nws lub neej, tiv thaiv qhov xav tau kev hloov pauv hloov pauv tag nrho.

Txo cov nqi tag nrho lub neej voj voog

Los ntawm lub neej- voj voog txoj kev xav, tsim nyog nce qib tiv thaiv corrosion tuaj yeem txo tag nrho cov nqi ntawm cov tswv cuab.

4. Ua raws li qhov yuav tsum tau muaj kev ntseeg siab hauv ib puag ncig tshwj xeeb

Nyob rau hauv cov xwm txheej xws li offshore cua zog (siab ntsev tsuag / av noo), tshuaj nroj tsuag (acidic gases), los yog cov cheeb tsam kub thiab av noo, qib tiv thaiv corrosion ncaj qha txiav txim siab qhov ua tau.

5. Ua raws li daim phiaj xwm txheej txheem thiab ib puag ncig yuav tsum tau ua

Ob Lub Xeev Grid thiab Southern Power Grid muaj cov kev qhia meej meej rau kev tiv thaiv kev tiv thaiv kev hloov pauv. Ntxiv mus, ntev - kev tiv thaiv kav ntev yuav txo qis kev ua haujlwm rov ua dua tshiab, txo qis VOC emissions thiab tsim khoom pov tseg, ua raws li cov qauv tsim ntsuab.

Common Corrosion Protection Failures hauv kev ua haujlwm

Xaus

Kev tiv thaiv corrosion theem ntawm transformer tso tsheb hlau luam tsis yog tsuas yog qhov teeb meem kev kho mob saum npoo xwb tab sis ib qho kev txiav txim siab rau kev nyab xeeb, kev pab cuam lub neej, kev lag luam, thiab kev ua raws li ib puag ncig. Kev xaiv tsim nyog ntawm qib kev tiv thaiv thiab kev ua raws li cov txheej txheem txheej txheej yog qhov tseem ceeb uas yuav tsum tau hais txog hauv kev tsim khoom thiab kev ua haujlwm ntawm transformer. Rau cov neeg siv, qhov chaw khiav hauj lwm yuav tsum tau txhais kom meej thaum lub sij hawm yuav khoom, thiab kev soj ntsuam kev lees paub yuav tsum tau ua raws li cov kev cai sib thooj. Txuag kev tiv thaiv corrosion zoo los txo cov nqi pib yog qhov tsis tsim nyog.
