Yuav ua li cas yog ib co hom ntawm post insulators?

Lub ntsiab zoo ntawm disc ncua kev kawm ntawv porcelain insulators muaj xws li: superior hluav taws xob rwb thaiv tsev kev ua tau zoo, muaj zog txhua yam kev pab txhawb nqa, muaj kuab paug tsis kam, thiab zoo tus kheej - ntxuav cov khoom.

Ua ntej, disc ncua kev kawm ntawv porcelain insulators muaj cov hluav taws xob rwb thaiv tsev zoo heev. Lawv tiv thaiv tam sim no los ntawm kev ntws los ntawm lub rwb thaiv tsev mus rau qhov tsis yog -cov khoom siv hluav taws xob, yog li tiv thaiv tus kheej thiab khoom siv kev nyab xeeb. Hauv siab -voltage kis tau tus mob, yog tias tam sim no xau mus rau cov pej thuam lossis lwm yam tsis yog- cov khoom siv hluav taws xob, nws tuaj yeem ua rau muaj kev nyab xeeb loj heev. Disc ncua kev kawm ntawv insulators, nrog lawv superior rwb thaiv tsev kev ua tau zoo, zoo tiv thaiv tej xwm txheej.

Thib ob, disc ncua kev kawm ntawv porcelain insulators muaj zog txhua yam kev txhawb nqa muaj peev xwm. Lawv tuaj yeem tiv taus qhov hnyav ntawm tus neeg xyuas pib thiab lawv tus kheej, nrog rau sab nraud quab yuam xws li cua siab thiab dej khov loads, ua kom tus neeg xyuas pib tuav txoj haujlwm ruaj khov hauv nws lub xeev ncua. Qhov kev ua haujlwm no yog qhov tseem ceeb rau kev tswj cov geometry ntawm cov kab sib kis thiab txo qis zog.

Tsis tas li ntawd, disc ncua kev kawm ntawv cov plooj (porcelain insulators) muaj cov pa phem zoo heev. Nrog rau kev ua qias tuaj ib puag ncig, qhov teeb meem ntawm cov av nkos ntawm cov khoom siv hluav taws xob tau dhau los ua qhov tseem ceeb. Disc suspension insulators, los ntawm kev siv lub kaus tshwj xeeb - zoo li tus qauv thiab cov khoom tsim, txhim kho lawv cov pa phem. Piv txwv li, ob npaug - txheej lub kaus- hom kev ua qias tuaj - cov kab hluav taws xob tiv thaiv muaj cov yam ntxwv xws li qhov deb ntawm qhov tob tob, qhib lub kaus, thiab du, tsis muaj ntug sab hauv daim tiab, uas tuaj yeem txo cov plua plav pov tseg thiab txhim kho cua thiab nag tus kheej- kev ua haujlwm huv.
