Kev txiav txim siab qhov zoo ntawm transformer porcelain bushings yuav tsum muaj kev ntsuam xyuas los ntawm plaub qhov ntev: kev tshuaj xyuas qhov muag, kev ntsuas hluav taws xob, kev sib khi pov thawj, thiab kev hloov pauv mus rau qhov chaw ua haujlwm. Kev kuaj pom pom yog qhov tseem ceeb, thaum kuaj hluav taws xob yog qhov tseem ceeb. Cov hauv qab no yog cov qauv txiav txim tshwj xeeb thiab cov ntsiab lus ua haujlwm:
Kev tshuaj xyuas qhov muag: xyuas kom tsis muaj lub cev tsis xws luag lossis muaj kab mob
Qhov tsos yog thawj qhov teeb meem hauv kev txiav txim siab siv tau ntawm cov plooj (porcelain bushing). Cov khoom hauv qab no yuav tsum tau kuaj xyuas:
Qhov chaw ntawm lub Bushing: Nws yuav tsum du thiab zoo, tsis muaj kab nrib pleb, puas, paug tawm, los yog enamel tev. Yog hais tias lub enamel peeling cheeb tsam tshaj 300mm², lub bushing yuav tsum tau hloov.
Kev huv huv thiab huv huv: Qhov saum npoo yuav tsum tsis muaj roj, plua plav, lossis cov khoom siv hluav taws xob tiv thaiv kom tsis txhob muaj hluav taws xob ntau.
Kev ncaj ncees ntawm Sheath Structure: Cov sheaths ntawm cov rwb thaiv tsev sib xyaw yuav tsum tsis txhob muaj cov kab nrib pleb, kev laus, los yog deformation los tiv thaiv flashover nyob rau hauv ib puag ncig ntub los yog pos huab.
Flange thiab Sealing Area: Qhov sib koom ua ke ntawm lub tes tsho plooj (porcelain) thiab cov hlau flange yuav tsum ruaj thiab nruj, coated nrog waterproof sealant, thiab tsis muaj cov cim ntawm loosening los yog roj to.
Roj Level Indicator (tseem siv tau rau roj-Sleeves Filled): Cov roj qib yuav tsum nyob rau hauv qhov kev teev tseg, tsis qis dua 1/3 ntawm cov cim qis qis thiab tsis pub tshaj 1/2 ntawm cov cim saum toj kawg nkaus, tsis muaj roj to.
