1. Tag nrho cov ncej insulators ua raws li gb8287 1 cov txheej txheem rau high voltage Post Porcelain Insulators thiab gb12744, muaj kuab paug resistant teb pas nrig ncej porcelain insulators, kuj ua raws li cov kev cai ntawm thoob ntiaj teb tus qauv iec168 "kuaj ntawm sab hauv thiab sab nraum zoov plooj (porcelain) los yog iav ncej insulators nyob rau hauv lub nruab nrog nominal voltage siab tshaj 1000 V" thiab IEC luam tawm 815 "qhia rau kev xaiv ntawm insulators nyob rau hauv tej yam kev mob phem".
2. Lub insulator muaj lub zog txhua yam, tsis tshua muaj kev tawg thiab kev ua haujlwm zoo thiab txhim khu kev qha.
3. Tsawg kub txhua yam muaj nuj nqi ntawm insulator yog zoo.
Txhawm rau txhawm rau txheeb xyuas qhov ntsuas kub tsis tshua muaj kev ua haujlwm ntawm cov khoom, qhov kev sim khov ntawm zsw1-110 / 4 insulator tau ua nyob rau hauv qhov ntsuas kub qis ntawm lub koom haum ntawm dej science ntawm Songliao dej kev txuag commission, ua raws li cov kev cai ntawm cov khoom siv hluav taws xob. hloov qhov kub ntawm sab nraum zoov thaum lub caij ntuj no. Tom qab ob peb lub voj voog kub, qhov ntsuas siv lead ua tau raug zigzag kev puas tsuaj sim ntawm qhov kub qis. Cov txiaj ntsig kev sim qhia tau hais tias lub zigzag puas lub zog ntawm cov insulator ntawm - 40 degree tsis muaj qhov pom tseeb hloov pauv piv nrog chav sov.
4. Zoo heev stain kuj.
Kev tiv thaiv kev ua qias tuaj ntawm insulator tsuas yog nyob ntawm cov khoom tsim thiab cov duab ntawm lub kaus tiab. Ntau txoj haujlwm tau ua tiav hauv qhov no. Los ntawm kev tsim kho kom zoo, kev sim ua kom muaj kuab lom thiab ua kom zoo dua qub thiab kev ua kom muaj kuab paug zoo, lub tsho insulator lub kaus nrog kev hloov cov kaus loj thiab me thiab cov tav hauv qab lub kaus yog txiav txim siab. Cov insulators nrog ntxiv voltage ntawm 126kV thiab 252kV, tortuous kev puas tsuaj load tsis tsawg tshaj li 12kV thiab creepage tshwj xeeb deb ntawm 25mm / kV tsim nrog lub kaus tiab tuaj yeem tiv taus siab ua haujlwm voltage ntev ntev nyob rau hauv qhov sib npaug ntsev ntom ntawm {{4 }}.12mg/cm2, uas yog, qhov kev ncua deb ntawm insulator qib III thiab qhov sib npaug ntsev ntom ntom ntawm qib IV. Insulators nrog ntxiv voltage ntawm 550kV thiab creepage qhov nrug ntawm 25mm / kV tuaj yeem ua haujlwm tau ntev hauv qab ntsev ntom ntawm 0.06mg / cm2. Cov pa phem tiv thaiv qib ntawm insulator yog thawj zaug hauv Suav teb. Nws qhov sib npaug ntsev qhov sib npaug yog ib feem peb siab dua li ntawm cov khoom zoo sib xws nrog tib lub nce toj qhov deb thiab sib npaug ntawm txoj kab uas hla lub kaus.
5. Kev tiv thaiv av qeeg siab.
Qhov ntxiv hluav taws xob ntawm 252kV thiab 550kV insulators tau sim rau kev tiv thaiv av qeeg nrog kev siv zog ntawm 9 hauv Beijing Institute of water resources and Hydropower Research, thiab cov khoom kuaj tau zoo lawm.
6. Tsawg xov tooj cua cuam tshuam.
Lub xov tooj cua cuam tshuam ntawm insulator nrog ntxiv voltage ntawm 550kV nyob rau hauv 1.1 lub sij hawm ntawm kev khiav hauj lwm theem siab voltage yuav tsum tsis txhob ntau tshaj 500 μ 5. Yog tsis pom corona hmo ntuj nyob rau hnub tshav ntuj, thiab pom corona voltage yog mus txog 450kv.
