Hauv kev ua haujlwm txhua hnub, yog tias peb tau ceev faj, peb yuav pom tias tus lej ntawm cov insulators thiab tus lej ntawm cov insulators ntawm kab ntawm cov qib sib txawv voltage sib txawv. Tom qab ntawd, peb puas tuaj yeem txiav txim siab qhov theem hluav taws xob ntawm kab los ntawm kev saib tus lej ntawm cov insulators hauv kev ua haujlwm?
Raws li qhov xwm txheej ib txwm, 1 insulator yog 6-10kV, 3 insulators yog 35kV, 7 insulators yog 110kV, thiab 11 insulators yog 220kV. Txawm li cas los xij, hauv qee thaj chaw uas muaj ib puag ncig muaj kuab paug loj heev, xws li nyob ib puag ncig cov chaw tsim tshuaj lom neeg thiab cov chaw tsim hluav taws xob, cov xov tooj ntawm cov insulators tau teeb tsa yuav nce ntxiv rau tib theem hluav taws xob.
Ib qho ntxiv, raws li DL/T741-2001 tus qauv, tus naj npawb ntawm cov hlua raug tshem tawm nrog cov txheej txheem txheej txheem ntawm 20kV yog 2, tus lej ntawm 35kV ncua kev tiv thaiv cov hlua yog 3, tus lej ntawm 66kV ncua kev tiv thaiv cov hlua yog 5, thiab tus naj npawb ntawm 110kV ncua kev tiv thaiv cov hlua yog Nws yog 7, tus naj npawb ntawm 220kV ncua kev tiv thaiv insulators yog 13, tus lej ntawm 330kV ncua kev tiv thaiv cov hlua hlua yog 17, thiab tus naj npawb ntawm 550kV ncua kev tiv thaiv cov hlua yog 25.
Tom qab cov insulator tau teeb tsa thiab ua haujlwm rau ib ntus, peb tuaj yeem siv txoj kev ntsuas qhov ntsuas hluav taws xob txhawm rau txhawm rau txheeb xyuas qhov faib hluav taws xob tus nqi ntawm cov insulator txhawm rau txiav txim siab nws lub xeev kev ua haujlwm los ntawm cov insulator faib cov khoom ntsuas hluav taws xob, thiab tiv thaiv insulator tsis zoo, tus nqi qis , thiab xoom tus nqi ua ntej.
