Lub luag haujlwm ntawm insulators yog dab tsi?

Lub luag haujlwm tseem ceeb ntawm cov insulators yog txhawm rau txhawb nqa thiab txhim kho cov neeg nqa khoom tam sim no, ua kom muaj kev rwb thaiv tsev zoo ntawm cov neeg nqa khoom tam sim no thiab hauv av. Insulators (feem ntau hu ua porcelain fwj) yog tsim los ntawm ob qhov chaw: ib feem ntawm cov plooj (porcelain) thiab cov hlau fittings, uas yog sib txuas nrog cov cement nplaum hauv nruab nrab. Cov plooj (porcelain) ua kom cov hluav taws xob zoo hluav taws xob muaj zog ntawm lub insulator, thiab cov hlau fittings yog siv los kho cov insulator.
Tempered iav insulators yog ib hom tshwj xeeb ntawm kev tiv thaiv rwb thaiv tsev uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob. Insulators ua si ob lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob siv hluav taws xob, uas yog kev txhawb nqa cov neeg siv khoom thiab tiv thaiv tam sim no los ntawm kev rov qab mus rau hauv av. Ob lub luag haujlwm tseem ceeb no yog cov insulators tuaj yeem ua tiav cov rwb thaiv tsev zoo.
Insulators tsis tsuas yog dais qhov hnyav ntawm cov khoom thauj khoom, xov hlau, thiab cov khoom siv hlau, tab sis kuj yuav tsum tiv taus cua loads, daus loads, hlau galloping, thiab cuam tshuam los ntawm kev ua haujlwm tsis zoo thaum lub sijhawm thauj mus los thiab kev teeb tsa nyob rau hauv huab cua tsis zoo, coj cov khoom tseem ceeb. Los ntawm cov kev xav ntawm hluav taws xob, cov insulators tsis tsuas yog yuav tsum tau insulate cov xov hlau los ntawm hauv av, tab sis kuj yuav tsum tiv thaiv overvoltage surges los ntawm xob laim thiab hloov ua haujlwm.
Thaum flashover tshwm sim vim qhov cuam tshuam ntawm qhov hluav taws xob, lub hauv paus overheating yuav tsis ua rau lub iav tempered ntawm lub insulator tawg. Txhua yam khoom sab nraud yuav muaj kev cuam tshuam rau kev ua haujlwm ntawm cov insulators, yog li ntawd, cov kev xav tau siab dua kuj tau muab tso rau pem hauv ntej rau kev tsim cov iav insulators. Cov qauv tsim ntawm iav insulators xav tau kev kho mob nruj, nrog rau kev tsim qauv nruj thiab lub hauv paus tsim nyog.
Cov ntaub ntawv txuas ntxiv;
Raws li cov qauv kev faib tawm sib txawv, cov insulators tuaj yeem muab faib ua cov hluav taws xob siab thiab tsis tshua muaj hluav taws xob, cov khoom siv hluav taws xob, cov hluav taws xob tiv thaiv hluav taws xob, thiab lub tes tsho insulators raws li lawv cov qauv. Cov plaub hom insulators no yog siv rau hauv ntau qhov chaw nrog kev txwv kev siv sib txawv thiab cov xwm txheej. Feem ntau siv insulators nyob rau hauv cov nyiaj siv ua haujlwm muaj xws li tus pin insulators, ncua kev kawm insulators, porcelain cross caj npab, npauj npaim insulators, qws insulators, thiab nro insulators.
Tsis tas li ntawd, cov qauv txheej txheem rau cov insulators tseem xav tau ntau yam kev ntsuas hluav taws xob, tshuab, lub cev, thiab ib puag ncig kev ntsuas yuav tsum tau ua ntawm cov insulators raws li lawv cov qauv thiab kev siv, txhawm rau txheeb xyuas lawv cov kev ua tau zoo thiab zoo. Insulator fittings yuav tsis tsim kom pom tseeb corona paug nyob rau hauv kev khiav hauj lwm voltage, vim hais tias insulators yog lug siv li, thiab lawv cov kev twb kev txuas fittings kuj yuav tsum tau interchangeable.
Muaj ob hom hluav taws xob ua haujlwm tsis raug ntawm cov insulators: flashover thiab tawg. Lub flashover thiab kev puas tsuaj hluav taws xob ua haujlwm tsis raug ua rau lub hom phiaj sib txawv thiab muaj ntau txoj hauv kev tshwm sim. Flashover tshwm sim nyob rau saum npoo ntawm lub insulator, qhov chaw hlawv cov cim tuaj yeem pom thiab kev ua haujlwm rwb thaiv tsev feem ntau tsis ploj. Kev puas tsuaj tshwm sim hauv cov insulator thiab raug tso tawm los ntawm lub cev ceramic ntawm lub hau hlau thiab cov hlau ko taw. Txawm hais tias tej zaum yuav tsis muaj qhov cim ntawm qhov chaw, kev ua haujlwm rwb thaiv tsev tau poob lawm.
