Thaum koj tab tom xav txog kev txhim kho lub tshuab cua sov tshiab, HVAC chav tsev, ntsuas kub, lossis ib qho khoom siv hluav taws xob rau qhov teeb meem, nws tseem ceeb heev kom paub tseeb tias koj cov hluav taws xob ntau npaum li cas.Circuit Court breakerstuaj yeem tuav ua ntej lub voj voog ncig.
Circuit Court breakers nyob rau hauv koj lub vaj huam sib luag hluav taws xob raug suav hais tias yog "Safety buffers." Lawv txoj hauj lwm yog txiav tawm ntawm lub hwj chim thaum lawv pom qhov dhau tam sim no tshaj nws qhov amperage. Thaum koj tsis ntsuas koj lub Circuit Court breaker lub peev xwm thauj khoom, koj khiav qhov kev pheej hmoo ntawm kev puas tsuaj rau koj cov khoom siv, lossis phem dua ... teeb tsa koj lub tsev rau hluav taws! Hauv qhov blog no, peb yuav dhau los ua qhov tseem ceeb hauv kev nkag siab ntau npaum li cas amperage koj lub voj voog tuaj yeem tuav tau.
Txhua yam khoom siv hluav taws xob uas koj siv yuav tsum muaj ib theem tshwj xeeb ntawm lub zog hluav taws xob kom nws ua haujlwm zoo. Feem ntau hu ua "Power Rating," qib kev thauj khoom no pab txiav txim siab npaum li cas koj lub cuab yeej tuaj yeem ua haujlwm yam tsis muaj cua sov.
Koj puas tau mus kav khw rau roj teeb, qhov muag teeb, lossis txawm tias lub tshuab nqus tsev thiab pom tej yam xws li '9-volt roj teeb' lossis '12-watt teeb qhov muag teev' lossis '20 amps ntawm lub zog?' Koj puas tau saib cov lej no thiab pom koj tus kheej nug…
WATT nws txhais li cas?
Zoo, ua ntej peb dhia mus rau hauv lub peev xwm thauj khoom thiab tag nrho lwm cov lus qhia, cia peb kawm me ntsis txog amps, watts, thiab volts.
Dab tsi yog amp?
Amp luv luv rau Ampere. Amps ntsuas tus nqi hluav taws xob ntws dhau los ntawm qhov muab rau hauv ib thib ob. Nyob rau hauv laymen cov ntsiab lus, tus naj npawb ntawm amps qhia ntau npaum li cas ntawm ib tug hluav taws xob tam sim no yog kos los ntawm lub hwj chim cables
volt yog dab tsi?
Voltage (volts, V) ntsuas qhov hluav taws xob muaj zog raug thawb los ntawm lub voj voog. Hauv lwm lo lus, tus naj npawb ntawm cov volts qhia koj tus nqi ntawm lub siab raug thawb
watt yog dab tsi?
Wattage ntsuas tus nqi hluav taws xob hluav taws xob uas lub cuab yeej siv. Watts yog chav ntsuas ntsuas uas qhia tias tag nrho cov hluav taws xob tam sim no ntws los ntawm cov khoom siv hluav taws xob(1).Los ntawm kev ntsuas tus nqi hluav taws xob hauv lub tsev siv, lub tuam txhab hluav taws xob tuaj yeem txiav txim siab koj daim nqi hluav taws xob.
Cia peb siv lub hose dej ua piv txwv!
ike hluav taws xob khiav los ntawm ib tug tam sim no, dej ntws los ntawm ib tug hose. Amps yuav yog qhov ntim ntawm cov dej uas ntws los ntawm lub hose, thaum qhov tseeb dej siab yuav yog qhov voltage(1). Watts ntawm qhov tod tes yog ncaj qha ntsig txog lub zog uas dej tuaj yeem muab tau. Piv txwv li, nws tuaj yeem ua lub zog lub log dej.
Koj yuav txiav txim siab li cas koj lub tsev qhov hluav taws xob?
Ampere tuav txwv rau Circuit Breakers
Circuit Court breakers yog tsim los 'tawg' los yog txiav tawm lub Circuit Court thaum lub hluav taws xob load tshaj nws ampere tuav txwv. Qhov no yog ib qho kev nyab xeeb feature tiv thaiv overheating thiab tej zaum yuav muaj hluav taws kub. Lub breaker lub peev xwm feem ntau yog qhia rau nws, piv txwv li, '20' ntawm qhov hloov pauv yog hais txog 20-amp Circuit Court breaker.
Ib qho tseem ceeb uas yuav tsum nco ntsoov yog tias cov hluav taws xob hluav taws xob tuaj yeem ua tau li ntawm 80 feem pua ntawm lawv cov amperage tag nrho. Qhov ntawd txhais tau tias 15-amp Circuit Court breaker tuaj yeem ua haujlwm nyob ib puag ncig 12-amps thiab 20-amp Circuit Court breaker tuaj yeem tuav txog 16 amps.
Circuit Breaker Vaj Huam Sib Luag Comments
Txiav txim siab tus nqi ntawm cov khoom siv hluav taws xob uas tuaj yeem tswj tau los ntawm lub tshuab hluav taws xob
Lub peev xwm ntawm lub Circuit Court breaker kuj txiav txim siab tus nqi ntawm cov khoom siv hluav taws xob uas nws tuaj yeem ua tau. Piv txwv li, ib qho 20-amp breaker tuaj yeem ua tau txog 2400 watts ntawm 120-volt kab (20A * 120V=2400W). Overloading lub Circuit Court breaker yuav ua rau nws mus 'trip' thiab disconnect cov hluav taws xob.
Nws yog ib qho tseem ceeb heev kom nkag siab ntau npaum li cas amperage koj cov cuab yeej hluav taws xob kos ua ntej txhim kho rau hauv koj lub thawv tawg. Txawm hais tias koj tab tom nrhiav rau nruab lub rhaub, AC chav tsev, lub teeb hloov, lossis GFCI qhov hluav taws xob, muaj ob peb kauj ruam koj yuav tsum ua.
Txheeb xyuas wattage (max zog ntsuas) ntawm koj lub cuab yeej. Qhov no feem ntau yog sau rau qhov chaw nyob tom qab ntawm lub cuab yeej.
Ntsuas qhov hluav taws xob ntawm lub voj voog koj xav nruab koj cov khoom siv hluav taws xob. Feem ntau cov khoom siv hluav taws xob hauv tsev yog 120V thiab qhov chaw lag luam loj dua yog 240V(5). Yog tias koj tsis paub meej, siv lub multimeter los ntsuas qhov voltage ntawm koj lub breaker(5).
Txhawm rau xam amperage, siv qhov sib npaug Amps=Watts/Volts. Piv txwv li, lub teeb 200W ntawm 120V Circuit Court yuav kos li 1.67 amps.
Xam qhov TOTAL amperage ntsuam xyuas ntawm txhua yam khoom siv. Xyuas kom tseeb tias lawv TSIS TAU tshaj 80 feem pua ntawm cov breaker tag nrho cov amperage.
Lub peev xwm tawg ntawm Circuit Court breaker yog dab tsi?
Hauv kev teeb tsa tsim nyog, lub Circuit Court-breaker tsis tas yuav tsum ua haujlwm ntawm nws qhov siab tshaj plaws tawg tam sim no (Icu). Vim li no, tus yam ntxwv tshiab tau qhia uas yog qhov kev pabcuam luv luv-circuit breaking peev (Ics). IEC 60947-2 qhia (Ics) raws li feem pua (25, 50, 75, 100 feem pua) ntawm (Icu).
Qhov ntsuas qhov muaj peev xwm tawg (Icu) lossis (Icn) yog qhov ua txhaum siab tshaj plaws-tam sim no lub Circuit Court-breaker tuaj yeem cuam tshuam zoo yam tsis muaj kev puas tsuaj. Cov no yog cov tam sim no siab heev uas tsis tshua muaj tshwm sim. Hauv qhov xwm txheej ib txwm muaj, qhov txhaum-tam sim no muaj txiaj ntsig tsawg dua li (Icu) ntawm Circuit Court breaker.
Ntawm qhov tod tes, (Ics) tuaj yeem suav tias yog cov dej ntws siab ntawm qhov tsis tshua muaj tshwm sim. Nws yog ib qho tseem ceeb uas (Ics) raug cuam tshuam nyob rau hauv cov xwm txheej zoo los xyuas kom meej tias lub Circuit Court breaker yuav tsum tau npaj tam sim rau rov kaw tom qab lub faulty Circuit Court tau kho.
Cov qauv xeem raws li hauv qab no: O - CO - CO (ntawm Ics)
Cov kev ntsuam xyuas ua raws li cov kab ke no yog npaj los xyuas kom meej tias lub Circuit Court breaker yog nyob rau hauv lub xeev zoo thiab muaj rau cov kev pab cuam ib txwm.
Rau cov hluav taws xob hluav taws xob hauv tsev, Ics=k Icn qhov twg cov txiaj ntsig rau qhov "k" tau piav qhia ntawm lub rooj XIV hauv IEC 60898.
Hauv Tebchaws Europe, nws yog ib qho kev ua lag luam siv ak yam ntawm 100 feem pua kom Ics=Icu.
