Paub Qhov Txawv Ntawm Miniature Circuit Breakers thiab Molded Case Circuit Breakers

Lub Npe: Paub Qhov Txawv NtawmCov Hluav Taws Xob Me MethiabCov Khoom Siv Hluav Taws Xob Moulded Case

Cov cuab yeej hluav taws xob (circuit breakers) yog ib feem tseem ceeb ntawm lub tsev lub tshuab hluav taws xob. Lawv pab tiv thaiv koj lub tsev, chaw ua haujlwm lossis cov khoom lag luam los ntawm kev siv hluav taws xob ntau dhau thiab luv luv. Ob lub cuab yeej hluav taws xob feem ntau siv yog lub cuab yeej hluav taws xob me me (MCB) thiab lub tshuab hluav taws xob molded case (MCCB). Txawm hais tias lawv ob leeg ua haujlwm tib lub hom phiaj, muaj qee qhov sib txawv ntawm lawv. Hauv cov blog no, peb yuav tshawb nrhiav cov qhov sib txawv no.

1. Qhov loj thiab daim ntawv thov
Qhov txawv tseem ceeb ntawmMCBthiabMCCByog lawv qhov loj. Raws li lub npe qhia, MCBs me dua thiab siv rau hauv cov ntawv thov tam sim no qis txog li 125 amps. Lawv feem ntau siv rau hauv cov ntawv thov hauv tsev thiab cov lag luam me. MCCBs, ntawm qhov tod tes, loj dua thiab tuaj yeem tswj cov khoom thauj tam sim no siab dua txog li 5000 amps. Lawv feem ntau siv rau hauv kev lag luam thiab kev lag luam uas xav tau lub zog ntau dua.

2. Muaj zog thiab ruaj khov
MCCB muaj zog dua thiab ruaj dua li MCB. Lawv tuaj yeem tiv taus kev ntxhov siab ntawm hluav taws xob ntau dua thiab tau tsim los kom tiv taus qhov chaw ib puag ncig hnyav.Cov MCCBfeem ntau yog ua los ntawm cov khoom siv muaj zog dua li cov khoom siv ceramic lossis cov yas molded dua liCov MCB, uas feem ntau yog ua los ntawm cov yas. MCBs yog tsim los siv rau hauv qhov chaw tsis hnyav thiab yuav tsum tsis txhob raug rau cov khoom siv corrosive heev lossis qhov kub thiab txias heev.

3. Txoj kev mus ncig
Ob qho tib si MCBs thiabCov MCCBLawv tsim los kom mus ncig thaum qhov tam sim no tshaj qhov txwv. Txawm li cas los xij, cov txheej txheem uas lawv siv los mus ncig txawv. Lub MCB muaj lub tshuab thermal magnetic trip. Lub tshuab siv ib daim hlau bimetal uas kub thiab khoov thaum qhov tam sim no tshaj qhov txwv, ua rau lub circuit breaker mus ncig. Lub MCCB muaj lub tshuab hluav taws xob mus ncig uas siv lub microprocessor los tshuaj xyuas qhov ntws tam sim no. Thaum qhov tam sim no tshaj qhov txwv, lub microprocessor xa ib lub teeb liab mus rau lub circuit breaker kom mus ncig.

4. Tus nqi
Cov MCBfeem ntau pheej yig dua liCov MCCBQhov no yog vim lawv yooj yim dua hauv kev tsim thiab ua los ntawm cov khoom siv pheej yig dua. Lawv kuj tsis ruaj khov dua li MCCBs thiab muaj peev xwm nqa tam sim no qis dua. MCCBs kim dua vim lawv cov qauv tsim thiab cov ntaub ntawv siv nyuaj, tab sis lawv ruaj khov dua thiab tuaj yeem tswj tau cov khoom thauj tam sim no siab dua.

5. Kev Txij Nkawm
Kev saib xyuas uas xav tau rau MCBs thiabCov MCCBtxawv heev. Lub MCB yooj yim hauv kev tsim thiab tsis xav tau kev saib xyuas ntau. Lawv yuav tsum tau kuaj xyuas tsis tu ncua los ntawm tus kws hluav taws xob thiab hloov yog tias muaj teeb meem. MCCBs, ntawm qhov tod tes, xav tau kev saib xyuas ntau dua, xws li kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv hluav taws xob, uas yuav dhau los ua qub dhau sijhawm thiab yuav tsum tau hloov.

Hauv kev xaus, MCB thiabMCCBmuaj tib lub luag haujlwm, uas yog los tiv thaiv lub tshuab hluav taws xob los ntawm kev overload thiab luv luv circuit. Txawm li cas los xij, raws li peb tuaj yeem pom, muaj qee qhov sib txawv ntawm ob qho. MCBs yog me dua, ruaj khov dua thiab pheej yig dua, thaumCov MCCBmuaj zog dua, ruaj khov dua thiab kim dua. Daim ntawv thov thiab cov kev xav tau tam sim no yog cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv ob qho tib si.
