Rwb thaiv tsev Resistance Test: Core Barrier Against Industrial Heater Leakage Hazards
Cov hluav taws xob xau yog ib qho ntawm feem ntau zais thiab txaus ntshai ua txhaum ntawm kev lag luam hluav taws xob cua sov, hem rhiav hluav taws xob kev nyab xeeb thiab cov khoom siv ruaj khov rau lub sijhawm ntev yam tsis muaj kev ceeb toom ntxov. Muaj ntau lub tshuab hluav taws xob xau hluav taws xob tshwm sim ntawm cov khoom siv nrog cov cua sov ua haujlwm thiab cov tsos zoo li qub, ua rau pom kev soj ntsuam pom tsis muaj zog tiv thaiv latent rwb thaiv tsev faults. Rwb thaiv tsev tiv thaiv kev ntsuas lub hom phiaj ntawm kev sib cais kev ua tau zoo ntawm cov cua sov sab hauv qhov chaw nyob thiab lub plhaub hlau, ua haujlwm zoo tshaj plaws kev tshawb nrhiav txhais tau tias txhawm rau tshuaj xyuas cov dej xau zais zais. Nrog rau 1MΩ tsim nyog qhov pib raws li tus qauv tseem ceeb, qhov kev tshawb pom no raug txiav txim siab txog kev noj qab haus huv ntawm rwb thaiv tsev, thiab kev ntsuas kub ntawm thermocouple pab txhawm rau txheeb xyuas cov rwb thaiv tsev laus inducements.
Rwb thaiv tsev tiv thaiv saum toj no 1MΩ sawv cev rau tag nrho cov tsim nyog lub rhaub kev nyab xeeb kev ua tau zoo. Standard industrial cua sov raj txais siab - purity magnesium oxide hmoov raws li cov khoom siv insulating, uas tuav cov rwb thaiv tsev zoo thiab siab ua haujlwm nyob rau hauv qhuav thiab kub kub. Tsim nyog rwb thaiv tsev kev ua tau zoo kiag li cais tawm tam sim no hauv cov cua sov raj ntawm lub plhaub hlau sab nraud, tsis txhob siv lub plhaub hluav taws xob thiab hluav taws xob tam sim no. Lub tshuab ua kom sov ua tau raws li tus qauv no tuaj yeem hloov kho mus ntev - lub sijhawm ua haujlwm tas mus li hauv cov qauv kev lag luam ib puag ncig nrog ultra- hluav taws xob muaj kev nyab xeeb tsawg.
Rwb thaiv tsev tsis kam qis dua 1MΩ cim kev ua haujlwm tsis zoo ntawm rwb thaiv tsev thiab muaj peev xwm to. Ntau yam kev lag luam ib puag ncig ua rau rwb thaiv tsev txo qis, suav nrog huab cua ntxeem tau, ntev - lub sij hawm siab - kub carbonization, nto conductive av tsub zuj zuj thiab foob kev puas tsuaj. Cov ntaub ntawv rwb thaiv tsev tsis muaj peev xwm cais tawm thiab tsim cov kab me me ntawm cov xov hlau sab hauv thiab lub plhaub. Txawm hais tias cov dej xau tam sim no tsis muaj zog nyob rau theem pib thiab tsis tuaj yeem ua rau tus neeg tiv thaiv tsis tuaj yeem, nws tsis tu ncua erodes rwb thaiv tsev qauv thiab ua kom muaj qhov tsis zoo.
Kev rwb thaiv tsev hnyav ua rau muaj kev cuam tshuam tsis zoo thiab cuam tshuam luv luv. Ntev -Lub sij hawm tsis ua tiav qhov kev tiv thaiv qis qis ua rau muaj kev cuam tshuam tsis tu ncua tam sim no, nthuav tawm cov rwb thaiv tsev puas tsuaj thiab thaum kawg tsim kev puas tsuaj mus tas li. Cov txheej txheem no induces intermittent plhaub electrification, nquag tiv thaiv tripping thiab txawm lub davhlau ya nyob twg luv Circuit Court burnout. Feem ntau ntawm lub caij sov lub caij ntuj sov faults nyob rau hauv cov chaw ua haujlwm ntub dej yog ncaj qha los ntawm kev ua haujlwm tsis zoo ntawm rwb thaiv tsev.
Thermocouple kub cov ntaub ntawv piav qhia lub hauv paus ua rau ntawm rwb thaiv tsev kev ua tau zoo degradation. Feem ntau cov rwb thaiv kev laus ua txhaum yog los ntawm qhov ntev - lub sij hawm overheating hauv zos thiab qhov kub tsis sib xws uas tau sau tseg los ntawm cov tshuab thermocouple. Kev ua haujlwm kub ntau dhau ua rau cov khoom siv rwb thaiv tsev carbonization, thaum kub hloov pauv ua rau cov txheej txheem loosening ntawm insulating txheej. Kev txheeb xyuas qhov ntsuas kub ntawm keeb kwm yav dhau los pab txhim kho kev ua haujlwm tsis zoo thiab tsis txhob rov ua haujlwm rwb thaiv tsev.
Kev ntsuas hluav taws xob tsis tu ncua ua cov txheej txheem kev tswj xyuas hluav taws xob kev nyab xeeb. Ua ntej- kev ua haujlwm rwb thaiv tsev tiv thaiv tshem tawm cov kev phom sij zais ntawm cov khoom siv tshiab thiab cov khoom siv tu. Kev ntsuam xyuas tsis tu ncua taug qab kev tiv thaiv kev tiv thaiv kev tiv thaiv kev laus ntawm cov khoom siv laus. Cov cua sov uas tsis tsim nyog yuav tsum tau nres thiab hloov tam sim ntawd kom tsis txhob muaj kev sib tsoo ntawm kev nyab xeeb. Kev soj ntsuam kev rwb thaiv tsev ua ke nrog cov thermocouple kub optimization schemes tswj kav ntev -lub sij hawm hluav taws xob kev nyab xeeb kev ruaj ntseg ntawm cov tshuab cua sov.
