Tam sim no, kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv cov khoom siv hluav taws xob tau dhau los ua kev txhim kho, thiab cov khoom siv hluav taws xob hloov hluav taws xob tau maj mam nthuav dav, thiab tuaj yeem dais lub zog tso zis ntau dua. Nrog rau qhov nce ntawm lub davhlau ya nyob twg ntim, qhov tsim nyog ntawm lawv lub luag haujlwm hauv cov tshuab thiab cov cuab yeej ua kom pom tseeb dua, thiab lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom cov yam ntxwv ntawm cov khoom. Cov hauv qab no tau qhia txog cov ntsiab lus tseem ceeb ntawm kev xaiv cov kab hluav taws xob muaj kev phom sij.
Ua ntej, tso zis zog daws teeb meem
Ib qho ntawm thawj yam uas yuav tsum tau xav txog yog lub peev xwm ntawm cov khoom siv los ua haujlwm nrog cov khoom siv hluav taws xob. Tsis muaj ib qho kev qhia tshwj xeeb rau kev txhais cov khoom siv hluav taws xob thiab cov yam ntxwv ntawm cov khoom siv davhlau ya nyob twg. Cov kev qhia tshwj xeeb thiab cov qauv ntawm cov davhlau ya nyob twg tsim nyob hauv Europe yog cov qauv IEC, thaum cov khoom tsim hauv Tebchaws Meskas yog cov qauv UL.
Qhov sib txawv ntawm ob qhov tshwj xeeb yog qhov loj heev. Cov kws tshaj lij engineers uas tsis nkag siab txog cov khoom lag luam txoj kev ua haujlwm muaj kev pheej hmoo siab heev ntawm kev siv cov khoom siv uas tsis ncav cuag lub zog tso zis, lossis siv cov khoom siv uas nws qhov tshwj xeeb tshaj qhov tsim nyog. Hauv Tebchaws Europe, qhov ntsuas tam sim no ntawm ib feem yog txiav txim siab los ntawm qhov kub thiab txias ntawm cov hlau conductor ntawm qhov ntsuas tam sim no. Thaum qhov kub ntawm tus pin hlau yog siab dua 45 ℃ tshaj qhov kub ntawm kev khiav hauj lwm, cov neeg ua haujlwm ntsuas qhov tseeb yuav siv qhov tam sim no raws li tus nqi ntsuas hluav taws xob (lossis siab dua tam sim no) ntawm cov khoom siv. Lwm yam khoom hauv IEC specifications yog qhov tso cai tam sim no, uas yog 80% ntawm cov tam sim no loj dua. Nyob rau hauv sib piv, UL specification teev cov nyiaj tam sim no rau cov tivthaiv raws li 90% ntawm cov tam sim no thaum kub ntawm cov hlau conductor yog siab tshaj qhov kev khiav hauj lwm kub ntawm 30 ℃. Nws tsis yog qhov nyuaj kom pom tias qhov kub thiab txias ntawm ib feem ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hlau yog qhov tseem ceeb heev hauv txhua qhov kev siv. Qhov no yog qhov tseem ceeb rau cov khoom siv kho tshuab. Vim tias cov cuab yeej siv tshuab feem ntau yuav tsum nyob rau hauv qhov kub ntawm 80 ℃ ua haujlwm ib puag ncig. Yog tias qhov ntsuas kub ntawm lub davhlau ya nyob twg yog 30 ℃ lossis 45 ℃ siab dua qhov ntsuas kub no, qhov ntsuas kub ntawm lub davhlau ya nyob twg yuav siab tshaj 100 ℃. Nyob ntawm seb hom nyiaj pub dawb thiab cov khoom siv rwb thaiv tsev tau xaiv rau cov khoom xaiv, cov khoom yuav tsum tau ua haujlwm ntawm qhov tam sim no tsawg dua qhov ntsuas tam sim no kom lawv tuaj yeem ua haujlwm tau zoo nyob rau hauv qhov kev xav tau kub. Qee qhov xwm txheej, cov khoom siv raw uas tsim nyog rau cov khoom ntim ntim ntim yuav tsis tuaj yeem suav rau cov kev xav tau tshem tawm cua sov zoo heev, yog li tam sim no ntawm cov khoom siv davhlau ya nyob twg yuav tsum tsawg dua li qhov ntsuas tam sim no.
