Lub luag hauj lwm ntawm Insulators nyob rau hauv Overhead Lines

Insulators yog ib yam khoom siv hluav taws xob cais tawm thiab yog cov khoom siv insulating zoo heev. Lawv ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob thiab tuaj yeem tiv thaiv cov khoom siv hluav taws xob zoo los ntawm kev puas tsuaj. Insulators tuaj yeem muab faib ua ntau hom, thiab ntau hom muaj qhov sib txawv ntawm daim ntawv thov kev siv, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv hluav taws xob. Insulators tuaj yeem raug cais los ntawm cov qauv rau hauv siab thiab qis voltage insulators, anti-fouling insulators, suspension insulators thiab bushing insulators. Cov hom insulators no tau siv nyob rau hauv ntau qhov chaw thiab kev lag luam thiab tau ua kom pom kev ua tau zoo hauv ntau yam lag luam. Cov insulators feem ntau siv nyob rau hauv cov nyiaj siv ua haujlwm xws li rab koob insulators, npauj npaim insulators, tshem tawm cov porcelain lub raj mis insulators, porcelain cross caj npab, pas nrig insulators thiab tensioning insulators, thiab lwm yam. Cov hluav taws xob tsis raug ntawm cov insulators feem ntau suav nrog flashover thiab tawg. Flashover tshwm sim nyob rau saum npoo ntawm insulators, thiab hlawv cov cim tuaj yeem pom. Feem ntau, kev ua haujlwm rwb thaiv tsev tsis ploj. Kev puas tsuaj tshwm sim hauv cov insulator, tawm los ntawm lub cev plooj (porcelain) nruab nrab ntawm lub hau hlau thiab cov hlau ko taw. Tej zaum yuav tsis muaj kab nyob rau ntawm qhov chaw, tab sis kev ua haujlwm rwb thaiv tsev tau ploj lawm. Nws kuj tseem tuaj yeem ua rau lub rwb thaiv tsev puas tag vim yog qhov tsim ntawm hluav taws xob arc. Rau kev tawg, kev saib xyuas yuav tsum tau them nyiaj rau kev kuaj xyuas cov cim tawm thiab hlawv cov xwm txheej ntawm cov taw hlau.
