7 Cov ntsiab lus koj yuav tsum paub txog Transformer Roj

Transformer roj yog ib hom roj ntxhia. Nws yog tau los ntawm natural petroleum los ntawm distillation thiab refining. Nws muaj cov yam ntxwv ntawm purity thiab stability, tsawg viscosity, zoo rwb thaiv tsev thiab zoo txias. Feem ntau transformer roj yog lub teeb daj pob tshab kua.

1-Lub luag haujlwm ntawm Transformer Roj

Lub luag haujlwm ntawm cov roj transformer tsis yog lubrication, tab sis cov hauv qab no.

• Rwb thaiv tsev

Transformer roj muaj lub zog rwb thaiv tsev ntau dua li huab cua. Cov ntaub ntawv rwb thaiv tsev rau hauv cov roj, tsis tsuas yog tuaj yeem txhim kho lub zog rwb thaiv tsev, tab sis kuj los ntawm kev yaig ntawm noo noo.

• Thaum tshav kub kub dissipation luag hauj lwm

Transformer roj muaj cov cua kub tshwj xeeb, feem ntau yog siv los ua cov dej txias. Lub tshav kub tsim los ntawm kev ua haujlwm transformer ua rau cov roj nyob ze ntawm lub hauv paus thiab winding nthuav dav thiab nce los ntawm tshav kub. Los ntawm cov roj convection nce thiab nqis, cua sov los ntawm lub dab dej kub kom ntseeg tau tias kev ua haujlwm ntawm lub tshuab hloov pauv.

• Arc Extinguishing nyhuv:

Nyob rau hauv cov roj Circuit Court breaker thiab transformer on-load regulator hloov, hu rau switching yuav tsim ib tug arc. Vim qhov zoo thermal conductivity ntawm transformer roj, thiab nyob rau hauv lub kub kub ntawm lub arc yuav sub-hu rau ib tug loj npaum li cas ntawm cov roj, uas ua rau lub siab ntau dua. Qhov no txhim kho qhov cuam tshuam kev ua haujlwm ntawm qhov nruab nrab, kom lub arc yog sai sai extinguished.

2-Cov Hom Cov Roj Hloov Hloov

Transformer roj feem ntau yog ua los ntawm cov roj ntxhia thiab muab faib ua ob pawg.

• Paraffin puag roj

• Naphthenic hauv paus roj

Paraffin raws li thiab naphthenic puag transformer roj muaj lawv tus kheej zoo thiab qhov tsis zoo. Cov ntsiab lus tseem ceeb yog raws li nram no:

(1) Paraffin-based roj muaj oxidation zoo dua li cov roj naphthenic. Txawm li cas los xij, cov khoom oxidation ua los ntawm cov roj paraffin yog qhov nyuaj rau yaj. Yog li ntawd, oxidation ntawm paraffin-raws li roj yuav tsim precipitates nyob rau hauv qab ntawm lub transformer. Qhov no cuam tshuam rau convection thiab kub dissipation ntawm transformer roj.

(2) Qhov ntsuas kub tsis tshua muaj qhov ua tau zoo ntawm cov roj naphthenic zoo dua li cov roj paraffin.

(3) Lub tshav kub dissipation ntawm cycloalkyl roj yog me ntsis zoo dua li cov roj paraffin. Nyob rau hauv tib lub viscosity, lub tshav kub hloov coefficient ntawm cycloalkyl roj yog 8 feem pua ​​~ 11 feem pua ​​siab dua li cov roj paraffin raws li 40 degree.

3-Qhov Performance index ntawm Transformer Roj

Thaum yuav thiab siv cov roj transformer, thov xav txog nws qhov kev ua tau zoo. Transformer roj tseem ceeb heev rau kev ua haujlwm ntev thiab nyab xeeb ntawm transformers. Nws muaj ntau yam kev ua tau zoo uas poob rau hauv peb pawg.

• Cov ntsuas hluav taws xob ua tau zoo: suav nrog hluav taws xob rwb thaiv tsev lub zog, tiv taus, dielectric poob yam, thiab lwm yam.

• Chemical Performance index: noo noo, acid nqi, sludge ntsiab lus, thiab lwm yam.

• Lub cev kev ua tau zoo ntawm lub cev: interfacial nro, viscosity, flash point, ncuav point, thiab lwm yam.

4-Kev Ua Haujlwm Ib puag ncig ntawm Transformer Roj

Kev khiav hauj lwm ib puag ncig ntawm transformer roj tsis muaj kev sib raug zoo nrog transformer muaj peev xwm. Nws feem ntau tsuas yog cuam tshuam nrog kev siv lub tshuab hloov pauv thiab qhov kub thiab txias ntawm qhov chaw teeb tsa.

Hauv Suav teb, piv txwv li, cov roj hloov pauv tau muab faib ua peb qhov ntau thiab tsawg: 10 #, 25 #, thiab 45 #. Qhov sib txawv ntawm cov lej qhia tias cov roj transformer muaj qhov sib txawv ntawm qhov khov. Piv txwv li, 25 # transformer roj muaj qhov chaw khov ntawm -25 degree Celsius.

5-Frequency Of Transformer Oil Hloov

Raws li lub zog ua haujlwm siab, cov roj transformer feem ntau yog hloov hauv li 3 xyoos. Thaum lub sij hawm siv lub transformer, cov roj theem yuav tsum tau soj ntsuam ntau zaus, thiab cov roj tshiab ntxiv yog tias cov roj qib zoo li qis dua.

6-Transformer Oil Failure

Transformer roj tsis ua haujlwm yog cuam tshuam nrog kub, noo noo, thiab oxidation.

Ua ntej, noo noo yog qhov tseem ceeb cuam tshuam. Nws txo cov rwb thaiv tsev kev ua haujlwm ntawm cov ntawv roj thiab ua kom cov rwb thaiv kev laus. Thiab micro dej yuav hloov mus rau hauv npuas thaum rhuab, uas yuav yooj yim ua rau lub cim ntawm ib nrab paug.

Cov nyhuv ntawm qhov kub ntawm cov roj feem ntau yog indirect. Piv txwv li, qhov kub tsis kam ntawm cov ntawv insulating yog qis dua cov roj. Thaum cov ntawv insulating muaj hnub nyoog, ntau qhov degraded furfural yuav nkag mus rau cov roj thiab ua rau lub neej ntawm lub transformer luv.

Thaum kawg peb tuaj rau qhov cuam tshuam ntawm huab cua ntawm cov roj. Cov pa oxygen hauv huab cua yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom tsis zoo ntawm cov roj. Piv txwv li, oxidation ntawm unsaturated ob daim ntawv cog lus nyob rau hauv cov roj tsim insoluble aldehydes thiab ketones. Cov no yog cov khoom tseem ceeb ntawm cov roj sludge. Thiab cov roj sludge muaj ntau yam kev mob tshwm sim, xws li cuam tshuam rau cov cua sov dissipation, adsorbing coj hais, thiab lwm yam.

7-Xaiv Transformer Roj

Thaum xaiv cov roj transformer, nws yuav pab tau koj pib los ntawm 7 lub ntsiab lus tseem ceeb hauv qab no:

• Qhov ntom me me li sai tau kom yooj yim nag lossis daus ntawm dej thiab impurities hauv cov roj.

• Viscosity yuav tsum yog nruab nrab, loj heev yuav cuam tshuam rau convection tshav kub dissipation, me me heev yuav txo qhov flash point.

• Flash point yuav tsum siab npaum li qhov ua tau, feem ntau yuav tsum tsis txhob qis dua 135 degree.

• Lub freezing point yuav tsum tsawg li tsawg tau.

• Qhov qis dua cov ntsiab lus ntawm impurities xws li acid, alkali, sulfur thiab tshauv, qhov zoo dua. Txhawm rau kom tsis txhob muaj lawv cov corrosion ntawm cov ntaub ntawv rwb thaiv tsev, cov xov hlau, cov roj tank, thiab lwm yam.

• Qhov degree ntawm oxidation yuav tsum tsis txhob siab dhau.

• Lub degree ntawm stability yuav tsum tsis txhob qis heev.
