Dab tsi ua rau MCCB & MCB Zoo sib xws?

Circuit Breakers yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob vim tias lawv muab kev tiv thaiv luv luv thiab overcurrent tej yam kev mob. Ob hom hluav taws xob Circuit Court breakers yog molded case circuit breakers (MCCB) thiab me me Circuit Court breakers(MCB). Txawm hais tias lawv tau tsim los rau qhov sib txawv ntawm qhov sib txawv thiab cov khoom siv tam sim no, ob qho tib si MCCBs thiab MCBs ua lub hom phiaj tseem ceeb ntawm kev tiv thaiv hluav taws xob. Hauv qhov blog no, peb yuav tshawb txog qhov zoo sib xws thiab qhov tseem ceeb ntawm ob hom hluav taws xob hluav taws xob.

Kev ua haujlwm zoo sib xws:

MCCB thiabMCBmuaj ntau yam zoo sib xws hauv cov haujlwm tseem ceeb. Lawv ua raws li cov keyboards, cuam tshuam cov dej ntws ntawm hluav taws xob thaum muaj hluav taws xob txhaum cai. Ob hom Circuit Court breaker yog tsim los tiv thaiv hluav taws xob los ntawm overloads thiab luv circuits.

Kev tiv thaiv luv luv:

Short circuits ua rau muaj kev pheej hmoo loj rau cov tshuab hluav taws xob. Qhov no tshwm sim thaum qhov kev sib txuas tsis xav tau tshwm sim ntawm ob lub conductors, ua rau muaj hluav taws xob tam sim ntawd. MCCBs thiab MCBs tau nruab nrog ib qho kev mus ncig ua si uas hnov ​​​​qhov tam sim no ntau dhau, tawg lub voj voog thiab tiv thaiv kev puas tsuaj lossis hluav taws kub.

Kev tiv thaiv overcurrent:

Hauv cov tshuab hluav taws xob, overcurrent tej yam kev mob tuaj yeem tshwm sim vim muaj hluav taws xob ntau dhau los yog overloading. MCCB thiab MCB ua tau zoo nrog cov xwm txheej zoo li no los ntawm kev txiav tawm ntawm lub voj voog. Qhov no tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob thiab pab tswj kev ruaj ntseg ntawm lub zog hluav taws xob.

Kev ntsuas voltage thiab tam sim no:

MCCB thiab MCB sib txawv ntawm qhov loj me thiab qhov ntsuas tam sim no. MCCBs feem ntau yog siv nyob rau hauv loj circuits los yog circuits nrog ntau dua tam sim no, feem ntau yog li ntawm 10 mus rau txhiab amps. MCBs, ntawm qhov tod tes, yog qhov tsim nyog rau cov hluav taws xob me me, muab kev tiv thaiv hauv thaj tsam li 0.5 txog 125 amps. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom tsim nyog ntawm Circuit Court breaker raws li cov khoom siv hluav taws xob kom ntseeg tau tias muaj kev tiv thaiv zoo.

Trip mechanism:

Ob leeg MCCB thiab MCB ntiav cov txheej txheem tripping los teb rau cov xwm txheej tam sim no txawv txav. Lub tripping mechanism nyob rau hauv MCCB feem ntau yog ib tug thermal-magnetic tripping mechanism uas combines thermal thiab magnetic tripping ntsiab. Qhov no ua rau lawv teb rau overload thiab luv luv Circuit Court tej yam kev mob. MCBs, ntawm qhov tod tes, feem ntau muaj cov txheej txheem thermal tripping uas feem ntau cuam tshuam rau cov xwm txheej dhau. Qee cov qauv MCB qib siab kuj tseem suav nrog cov khoom siv hluav taws xob tawm mus rau qhov tseeb thiab xaiv kev taug kev.

Muaj kev nyab xeeb thiab txhim khu kev qha:

MCCB thiab MCB ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuab hluav taws xob. Yog tias tsis muaj cov kab hluav taws xob no, kev pheej hmoo ntawm hluav taws xob hluav taws xob, khoom siv puas tsuaj, thiab kev raug mob rau tib neeg tau nce ntau ntxiv. MCCBs thiab MCBs ua rau muaj kev nyab xeeb ntawm kev teeb tsa hluav taws xob los ntawm kev qhib lub voj voog tam sim ntawd thaum kuaj pom qhov txhaum.
