TusTus Nqi Acid(lossis cov acid) ntawm cov roj hloov roj hloov pauv yog atseem ceeb parameterQhia txog qib ntawm cov kuab paug acidic tsim vim cov roj degradation (oxidation). Ntawm no yog cov ncauj lus kom ntxaws:
Nws ntsuas dab tsi:
Tusconcentration ntawm acidic Cheebtsam(feem ntau cov organic acids, tab sis kuj inorganic acids lossis oxidation los ntawm - cov khoom) hauv cov roj.
Qhia nyob rau hauvMilligrams ntawm cov poov tshuaj hydrocide (koh) yuav tsum tau neutralize cov kua qaub hauv ib gram roj (mg koh / g).
Vim li cas nws tseem ceeb:
Kev Nyab Xeeb:Acids tawm tsam cellulose rwb thaiv tsev cellulose cellulose rulfulation rwb thaiv tsev (ntawv, nias) thiab cov hlau, tank), nrawm nrawm thiab ua rau ua tsis tiav.
Sludge tsim:Acids txhawb kev tsim ntawm insoluble sludge, uas txo kev hloov kho tshav kub (ua kom muaj kev kub ntxhov.
Dielectric lub zog:Thaum tsis yog ib qho kev sib raug zoo 1-rau-1, cov kua qaub tsis sib haum tau txuas rau cov roj ntau zaus, uas thaum kawg kev hloov kho cov khoom.
Qhov taw qhia ntawm oxidation:Nws yog qhov taw qhia tseem ceeb ntawm cov roj oxidation xeev thiab tag nrho kev laus.
Cov theem tau lees paub:
Cov Roj Tshiab:Feem ntau tsawg, feem ntau< 0.01 mg KOH/g(ib tus qauv zoo li IEC 60296 lossis ASTM D3487).
Hauv -}} Cov Roj Pab:Qhov kev txwv siab tshaj plaws yog txhais los ntawm cov qauv thiab kev coj ua hluav taws xob:
Cov kev txiav txim ua ntau yam: 0.1 txog 0.3 mg koh / gyog siv dav ua qhov pib rau kev kho kom haum (xws li reclamation lossis hloov).Kev sab laj ntawm tus neeg tsim khoom lag luam cov lus pom zoo thiab cov qauv tsim nyog (zoo li IEEE C57.106, iec 60422) yog qhov tseem ceeb heev.
Cov lus qhia dav dav:
Hauv qab no 0.1 mg Koh / g: feem ntau lees txais.
{{00.1 - 0.3 mg koh / g: qhia tias ua rau muaj kev ua kom nquag ua haujlwm. Kev tshawb nrhiav thiab kev npaj rau kev kho cov kev kho (roj kev hloov pauv / hloov pauv) yog xav tau.
Saum toj no 0.3 mg koh / g:Ntseeg tau tias muaj kev cuam tshuam tseem ceeb.Roj reclamation lossis hloov feem ntau yuav tsum tau nrawm los tiv thaiv kev puas tsuaj thiab tsis ua haujlwm. Sludge tsim los ua yuav heev.
Cov Qauv Kuaj:
ASTM D974:Txoj kev ntsuas qauv rau cov kua qaub thiab lub hauv paus los ntawm cov xim - Qhov taw qhia lub kaum (feem ntau, tab sis tsawg dua rau cov roj dub).
ASTM D664:Txoj kev ntsuas ntsuas rau cov khoom siv acid los ntawm cov khoom siv acid los ntawm cov khoom siv roj carration (ntau dua, tshwj xeeb tshaj yog rau cov roj tsaus dua / siv, kuaj pom cov kua qaub dawb).
IEC 62021-1:Insulating kua - kev txiav txim siab ntawm acidity - Tshooj 1: Tsis siv neeg potentiometric ib lub kaum.
Kev sib raug zoo rau lwm qhov kev ntsuam xyuas:
Acid nqi feem ntau correlates nrogInterfacial nro (IFt)Cov. Raws li cov kua qaub nce (cov acid acid), iFt txo qis. Ob qho tib si yog cov ntsuas muaj zog ntawm oxidation thiab sludge muaj peev xwm.
Dielectric dissipation Factor (DDF lossis ziab delta)Kuj tseem tuaj yeem nce nrog acid tsim.
Hauv cov ntsiab lus:Cov txiaj ntsig acid yog qhov ntsuas tseem ceeb ntawm transformer roj kev noj qab haus huv. Ib qho kev xaiv cov cim acid nquag ua haujlwm oxidation thiab tsim kev ua kom muaj xeb, sludge {{1} m ywm forming acids.Tswj cov acid muaj txiaj ntsig zoo hauv qab 0.1 mg koh / g yog qhov tseem ceeb rau kev txhim khu kev qha ua haujlwm thiab kev ua haujlwm ntev. Kev sim ua ntu zus thiab kev nqis tes ua thaum nws mus txog cov txheej txheem lossis ntau dua 0.1-0.3 mg koh / g yog qhov tseem ceeb ntawm kev coj ua.Nco ntsoov hais txog cov qauv tsim qauv qhia tshwj xeeb thiab cov qauv kev lag luam cuam tshuam rau kev txwv zoo thiab kev ua.
