Tag nrho cov ncej insulators ua raws li gb8287 1 cov kev cai ntawm cov txheej txheem rau high voltage Post Porcelain Insulators thiab gb12744, muaj kuab paug resistant sab nraum zoov pas nrig ncej porcelain insulators, kuj ua raws li cov kev cai ntawm thoob ntiaj teb tus qauv iec168 xeem ntawm sab hauv tsev thiab sab nraum zoov plooj (porcelain) los yog iav post insulators rau cov tshuab nrog nominal voltage siab dua 1000 V thiab IEC luam tawm 815 phau ntawv qhia rau xaiv cov insulators nyob rau hauv cov pa phem.
Lub insulator muaj lub zog txhua yam, tsis tshua muaj dispersion thiab ua haujlwm zoo thiab txhim khu kev qha. Txhawm rau ntsuas qhov ntsuas kub tsis tshua muaj hluav taws xob ntawm cov khoom, qhov kev sim khov ntawm zsw1-110 / 4 insulator tau ua los ntawm kev simulating qhov kev hloov ntawm sab nraum zoov kub hauv lub caij ntuj no hauv qhov ntsuas kub qis ntawm lub koom haum dej. kev kawm. Tom qab ob peb lub voj voog kub, qhov kev sim siv lead ua yuav raug khoov tsis ua haujlwm ntawm qhov kub thiab txias. Cov txiaj ntsig kev sim qhia tau hais tias qhov khoov tsis ua haujlwm lub zog ntawm cov insulators ntawm - 40 degree tsis muaj qhov pom tseeb hloov pauv piv nrog chav sov.
Kev ua qias tuaj ntawm cov insulators feem ntau yog nyob ntawm cov qauv ntawm cov khoom thiab cov duab ntawm lub kaus tiab. Ntau txoj haujlwm tau ua tiav hauv qhov no. Los ntawm kev tsim kho kom zoo, kev kuaj kev ua qias tuaj yeem ua kom zoo dua qub thiab kev ua kom muaj kuab paug zoo, lub tsho insulator lub kaus nrog lub kaus loj thiab me thiab cov tav hauv qab lub kaus yog txiav txim siab. Lub insulator nrog ntsuas voltage ntawm 126kV thiab 252kV, dabtsi yog khoov tsis ua hauj lwm load tsis tsawg tshaj li 12kV thiab creepage tshwj xeeb deb ntawm 25mm / kV tsim nrog lub kaus tiab.
Raws li qhov sib npaug ntsev ntom ntom ntawm {{0}}.12mg / cm2, nws tuaj yeem tiv taus lub zog ua haujlwm siab rau lub sijhawm ntev, uas yog, qhov kev ncua deb ntawm insulator qib III, thiab tuaj yeem tiv taus cov pa phem ntawm sib npaug ntsev ntom ntawm qib IV. Insulators nrog ntsuas voltage ntawm 550kV thiab creepage tshwj xeeb nrug ntawm 25mm / kV tuaj yeem ua haujlwm tau ntev hauv qab qhov sib npaug ntsev ntom ntawm 0.06mg / cm2. Cov pa phem tiv thaiv qib ntawm insulator yog ua nyob rau hauv Suav teb. Nws qhov sib npaug ntsev ntom ntom yog ib feem peb siab dua li ntawm cov khoom zoo sib xws nrog tib lub nce toj nrug thiab sib npaug ntawm txoj kab uas hla lub kaus. Cov khoom ua qias tuaj yeem tiv taus qhov ntsuas hluav taws xob ntawm cov rwb thaiv tsev yog ua los ntawm sab qaum teb sab hnub tuaj hluav taws xob ntsuas hluav taws xob thiab lub koom haum tshawb fawb. Cov txiaj ntsig tau pom tias muaj kev tiv thaiv siab ntsev ntom ntom ntawm insulator nrog creepage tshwj xeeb nrug ntawm 31mm / kV yog 0.25mg / cm.
