27.5kV Composite Substation Post Insulators Rau Railway
Composite ncejInsulator nyob rau hauv ntau hom muaj kev ua haujlwm sib txawv, cov qauv qhov siab thiab qhov kev ncua deb kuj yog ib qho tsis zoo ib yam, pillar composite insulator feem ntau yog siv hauv transformer substation, thiab muaj qhov zoo hydrophobic nrhiav tsis kam, aging kuj, thiab hluav taws xob yaig kuj, siab tensile zog thiab dabtsi yog khoov. lub zog, nws lub zog ua haujlwm siab, kev poob siab, kev poob siab thiab kev ua haujlwm tawg tawg yog qhov zoo, Lub teeb yuag, yooj yim installation thiab txij nkawm, sab sauv thiab qis kawg ntawm qhov loj me thiab cov khoom siv porcelain post insulator installation loj yog tib yam, tuaj yeem ua tau. siv interchangeably.
Dab tsi yog cov yam ntxwv ntawm kev sib xyawncejinsulators?
ib. Cov khoom siv hluav taws xob tom qab tuaj yeem siv tau zoo siv txoj hauv kev nqaim kom qhib qhov hluav taws xob sib kis, thiab tsim nyog rau kev hloov pauv hauv nroog network. Nws tuaj yeem txo qhov siab ntawm tus ncej thiab ntauwd, thiab txuag tau ntau tus neeg ua haujlwm, khoom siv thiab nyiaj txiag. Vim nws lub zog khoov siab, nws tuaj yeem tiv thaiv qhov kev sib tsoo cascade tau yooj yim tshwm sim los ntawm porcelain hla caj npab, thiab nws yog cov khoom lag luam uas porcelain hla caj npab hloov tsis tau. Qhov loj me, lub teeb yuag, muaj zog poob siab thiab cuam tshuam, tsis xav tau kev ntxuav ntawm phau ntawv, muab kev lees paub rau kev ua haujlwm nyab xeeb. Cov khoom no siv INTEGRAL bar tsim, compact qauv, zoo, hnyav yog tib qib porcelain thiab iav insulator 1/10, kev thauj mus los thiab kev teeb tsa yooj yim heev.
Haum rau qhov chaw qias neeg, siab mechanical tensile load, ntev ncua sij hawm thiab compact kab. Cov pa phem hluav taws xob hluav taws xob yog 30 feem pua -50 feem pua siab dua li cov plooj (porcelain) thiab iav insulators ntawm tib qib. Kev ua haujlwm ruaj khov ntawm -60 degrees -- ntxiv rau 200 degrees ambient kub; Cov qauv tsim tsis tawg tau txais yuav, tsis tas yuav ntsuas tus nqi xoom hauv kev ua haujlwm. Kev ua tau zoo ntawm hluav taws xob, lub zog ua haujlwm siab, lub zog tensile thiab khoov lub zog ntawm epoxy iav kos duab pas nrig nrog cov khoom siv sab hauv yog 2 npaug siab dua li cov hlau zoo tib yam, thiab 8 ~ 10 npaug siab dua li cov khoom siv porcelain muaj zog, uas txhim kho tau zoo. kev ntseeg siab ntawm kev ua haujlwm nyab xeeb.
b. Kev ua haujlwm zoo los tiv thaiv fouling, tiv thaiv flashover muaj zog, nws qhov kev tiv thaiv ntub dej thiab kev ua pa phem rau qhov hluav taws xob ntawm tib qhov nce mus deb ntawm cov plooj (porcelain insulator) 2 ~ 2.5 zaug. Thiab tsis tas yuav tsum tau ntxuav, tuaj yeem ua rau muaj kuab paug hnyav kom khiav nyab xeeb.
c. Qhov loj me, lub teeb yuag (tsuas yog 1/6 ~ 1/9 ntawm tib qib voltage porcelain insulator), lub teeb qauv, yooj yim rau kev thauj thiab teeb tsa.
