LUB HAUJ LWM NTAWM COV INSULATERS

Muaj ntau cov insulators zoo li disc-puab dai rau ntawm ib kawg ntawm lub pej thuam txuas hlau high-voltage. Nws yog los ua kom qhov deb ntawm creepage nce ntxiv. Nws feem ntau yog ua los ntawm iav lossis ceramics, uas hu ua insulator. Yuav kom tiv thaiv cov hmoov av thiab lwm yam khoom tsis huv los ntawm kev lo rau ntawm qhov chaw ntawm insulator, tsim ib txoj kev uas raug tawg los ntawm lub zog hluav taws xob hla lub insulator, uas yog, creepage, yog li ua kom qhov deb ntawm qhov chaw, uas yog, creeping deb. Qhov deb ntawm kev tso tawm raws qhov chaw insulating, uas yog, qhov deb ntawm qhov xau, hu ua creeping deb. Qhov deb ntawm qhov chaw / qhov hluav taws xob siab tshaj plaws ntawm lub cev, raws li qib ntawm kev ua qias tuaj, qhov deb ntawm creepage feem ntau yog 31 mm / kV hauv thaj chaw muaj kuab paug ntau.

Ib qho insulator uas tsis muaj nqi yog hais txog ib qho insulator uas nws qhov kev faib tawm thoob plaws lub insulator ze li lossis sib npaug rau xoom thaum lub sijhawm ua haujlwm.

Kev cuam tshuam ntawm cov insulators xoom lossis qis tus nqi: Kev rwb thaiv tsev ntawm cov xov hlau nyob ntawm txoj hlua insulator. Vim yog qhov tsis zoo ntawm kev tsim khoom lossis cov teebmeem sab nraud, kev ua haujlwm rwb thaiv tsev ntawm cov insulators yuav txuas ntxiv mus tsis zoo. Thaum cov rwb thaiv tsev thiab kev tiv thaiv rwb thaiv tsev raug txo qis lossis xoom, nws hu ua qis lossis xoom. Cov insulators xoom, peb tau sim cov kab, thiab qhov sib piv ntawm cov insulators xoom lossis qis tus nqi yog siab txog li 9%, uas yog lwm qhov laj thawj tseem ceeb rau qhov ceev ceev ntawm cov kab ntawm lub tuam txhab. Qhov kev cuam tshuam capacitive ntawm lawv tuaj yeem txo qhov poob ntawm tam sim no.
