Ua ntej, cia peb txheeb xyuas cov haujlwm ntawmTsawg voltage Circuit Court breakerthiab fuse nyob rau hauv qis voltage hluav taws xob Circuit Court:
1. Tsawg Voltage Circuit Breakers
Nws yog siv rau kev tiv thaiv tam sim no ntawm tag nrho cov khoom siv hluav taws xob kawg, rau kev tiv thaiv kev thauj khoom tam sim no ntawm lub cev thiab ceg xaus ntawm cov kab xa tawm, thiab rau kev tiv thaiv tam sim no ntawm qhov kawg ntawm cov kab xa tawm.
Thaum overload, luv luv Circuit Court, los yog voltage poob tshwm sim nyob rau hauv txoj kab, lub instantaneous mus txawv tebchaws ntawm tsawg-voltage Circuit Court breaker txiav tawm lub hwj chim mov los tiv thaiv kev ruaj ntseg ntawm txoj kab.
Residual Current Circuit BreakerSiv rau Kev Tiv Thaiv Tus Kheej
2. Fuses
Nws yog siv rau kev tiv thaiv overload ntawm load tam sim no nyob rau hauv kab thiab luv luv Circuit Court tiv thaiv ntawm theem thiab theem thiab txheeb ze av.
Lub fuse yog ib qho khoom siv tiv thaiv.Thaum qhov tam sim no dhau ntawm tus nqi ruaj khov thiab dhau los ntawm lub sijhawm txaus, lub melts melts, thiab lub voj voog txuas nrog nws raug txiav, uas muab kev tiv thaiv overload los yog luv luv tiv thaiv Circuit Court thiab khoom siv.
Los ntawm kev txheeb xyuas yooj yim, nws tuaj yeem paub tias cov hluav taws xob hluav taws xob thiab cov fuses yuav tsum tau muab tso rau hauv cov khoom siv hluav taws xob tsawg, txawm tias siv rau kev lag luam lossis kev siv hauv tsev.
Ua cov kws tshaj lij hluav taws xob txhua tus paub: Kev ua haujlwm hluav taws xob yuav tsum ua raws li "Low Voltage Electrical Device Regulations".Muaj ob tshooj nyob rau hauv "Low Voltage Electrical Device Regulations" uas qhia tshwj xeeb uas tsim cov installation specifications ntawm lub ntsiab hloov (circuit breaker) thiab fuse.
Kev sib piv ntawm Circuit Court breaker thiab fuse thiab kev sib piv ntawm cov hlau yuav tsum tau them nyiaj mloog rau hauv cov khoom siv hluav taws xob tiag tiag.
Qhov ntsuas fuse tam sim no ntawm lub cuab yeej fuse hauv Circuit Court yuav tsum siab dua lossis sib npaug ntawm 1.2 txog 1.3 npaug ntawm qhov ntsuas tam sim no ntawm lub Circuit Court breaker.
Lub yaj tam sim no ntawm lub fuse yog tsawg dua 0.8 npaug ntawm qhov kev nyab xeeb tam sim no ntawm tus neeg xyuas pib.
Feem ntau hais lus, cov yaj tam sim no ntawm fuse yuav tsum loj dua li qhov ntsuas tam sim no ntawm Circuit Court breaker thiab tsawg dua qhov muaj peev xwm nqa tau zoo ntawm tus neeg xyuas pib.
Qhov ntsuas tam sim no ntawm Circuit Court breaker yuav tsum siab dua lossis sib npaug ntawm cov kab tam sim no, thiab cov kab hluav taws xob tam sim no yuav tsum yog 1.2 npaug ntau npaum li cov kab tam sim no.Nws kuj tuaj yeem kho cov kab thauj khoom kom zoo raws li qhov xwm txheej ntawm cov kab thauj khoom, xws li hluav taws xob cua sov.Tab sis qhov ntsuas tam sim no ntawm Circuit Court breaker yuav tsum tsawg dua li lub fuse yaj tam sim no.
Tsis tas li ntawd, muaj ntau yam khoom siv hluav taws xob uas tsis muaj fuses, uas tsis muaj kev nyab xeeb thiab tsis raug.Thaum muaj kev txhaum ntawm txoj kab, nws yooj yim heev ua rau hluav taws.Hauv kev sib tsoo hluav taws yav dhau los, fuses tsis tau teeb tsa lossis tsis raug.Muaj ntau yam uas yuav tsum tau kawm.Yog li ntawd, fuses thiab Circuit Court breakers yuav tsum tau nruab rau hauv lub tsev kho kom zoo nkauj.Tsis txhob txhawj xeeb thiab nyab xeeb ua ntej.
