MCCB Vs MCB Vs RCBO: Lawv Txhais Li Cas?

Ib qho MCCB yog ib qho molded case Circuit Court breaker, thiab MCB yog ib qho me me Circuit Court breaker. Lawv ob leeg siv nyob rau hauv hluav taws xob circuits los muab kev tiv thaiv overcurrent. MCCBs feem ntau yog siv nyob rau hauv lub tshuab loj, thaum MCBs yog siv nyob rau hauv me me circuits.

Ib qho RCBO yog kev sib txuas ntawm MCCB thiab MCB. Nws yog siv nyob rau hauv circuits qhov twg ob qho tib si overcurrent thiab luv-circuit tiv thaiv yuav tsum tau. RCBOs tsis tshua muaj ntau dua li MCCBs lossis MCBs, tab sis lawv loj hlob hauv cov koob npe vim lawv muaj peev xwm muab ob hom kev tiv thaiv hauv ib lub cuab yeej.

MCCBs, MCBs, thiab RCBOs txhua tus ua haujlwm zoo ib yam: los tiv thaiv hluav taws xob hluav taws xob los ntawm kev puas tsuaj vim yog cov xwm txheej tam sim no ntau dhau. Txawm li cas los xij, lawv txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. MCCBs yog qhov loj tshaj plaws thiab kim tshaj plaws ntawm peb txoj kev xaiv, tab sis lawv tuaj yeem tswj cov dej ntws siab dua thiab muaj lub neej ntev dua.

MCBs yog me dua thiab tsis tshua kim, tab sis lawv muaj lub neej luv dua thiab tuaj yeem tswj tau qis qis dua.RCBOs yog qhov zoo tshaj plawskev xaiv, thiab lawv muab cov txiaj ntsig ntawm MCCBs thiab MCBs hauv ib lub cuab yeej.

Thaum muaj qhov txawv txav hauv Circuit Court, MCB lossis me me Circuit Court breaker cia li hloov lub Circuit Court tawm. MCBs yog tsim los kom nkag siab yooj yim thaum muaj qhov tam sim no ntau dhau, uas feem ntau tshwm sim thaum muaj qhov luv luv.

MCB ua haujlwm li cas? Muaj ob hom kev sib cuag hauv MCB - ib qho ruaj khov thiab lwm yam txav tau. Thaum qhov tam sim no ntws los ntawm lub voj voog nce, nws ua rau cov neeg txav tau txav mus los ntawm kev sib txuas ntawm cov neeg sib txuas ruaj khov. Qhov no ua tau zoo "qhib" Circuit Court thiab nres qhov ntws ntawm hluav taws xob los ntawm cov khoom siv loj. Hauv lwm lo lus, MCB ua raws li kev ntsuas kev nyab xeeb los tiv thaiv circuits ntawm overloads thiab puas.

MCCB (Molded Case Circuit Breaker)

MCCBs yog tsim los tiv thaiv koj Circuit Court los ntawm overloading. Lawv muaj ob txoj kev npaj: ib qho rau overcurrent thiab ib qho rau over-temperature. MCCBs kuj tseem muaj qhov hloov pauv hloov pauv rau lub voj voog, nrog rau cov kev sib cuag bimetallic uas nthuav lossis cog lus thaum MCCB qhov kub hloov pauv.

Tag nrho cov ntsiab lus no los ua ke los tsim cov khoom siv ruaj khov, ruaj khov uas tuaj yeem pab ua kom koj lub voj voog muaj kev nyab xeeb. Ua tsaug rau nws tus qauv tsim, MCCB tuaj yeem yog qhov kev xaiv zoo rau ntau yam kev siv.

Ib qho MCCB yog lub tshuab hluav taws xob hluav taws xob uas pab tiv thaiv cov khoom siv los ntawm kev puas tsuaj los ntawm kev cuam tshuam cov khoom tseem ceeb thaum tam sim no tshaj li tus nqi preset. Thaum qhov tam sim no nce, cov kev sib cuag hauv MCCB nthuav dav thiab sov kom txog thaum lawv qhib, yog li rhuav tshem lub voj voog. Qhov no tiv thaiv kev puas tsuaj ntxiv los ntawm kev ruaj ntseg cov khoom siv los ntawm cov khoom tseem ceeb.

Dab tsi ua rau MCCB & MCB Zoo sib xws?

MCCBs thiab MCBs yog ob qho tib si Circuit Court breakers uas muab cov khoom tiv thaiv rau lub zog hluav taws xob. Lawv feem ntau yog siv nyob rau hauv qis voltage circuits thiab yog tsim los rau kev nkag siab thiab tiv thaiv Circuit Court los ntawm luv luv circuits los yog overcurrent xwm txheej.

Thaum lawv sib koom ntau qhov sib xws, MCCBs feem ntau yog siv rau cov kab hluav taws xob loj dua lossis cov uas muaj hluav taws xob ntau dua, thaum MCBs zoo dua rau cov circuits me. Ob hom Circuit Court breaker ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm cov tshuab hluav taws xob.

Dab tsi txawv MCCB Los ntawm MCB?

Qhov sib txawv tseem ceeb ntawm MCB thiab MCCB yog lawv lub peev xwm. MCB muaj qhov ntsuas qis dua 100 amps nrog qis dua 18,000 amps cuam tshuam kev ntsuas, thaum MCCB muab amps qis li 10 thiab siab li 2,500. Tsis tas li ntawd, MCCB nta ib qho kev hloov pauv mus txawv tebchaws rau cov qauv siab dua. Yog li ntawd, MCCB yog qhov tsim nyog rau cov khoom siv hluav taws xob uas xav tau lub peev xwm ntau dua.

Hauv qab no yog ob peb qhov tseem ceeb qhov sib txawv ntawm ob hom Circuit Court breakers:

Ib qho MCCB yog ib hom kev tiv thaiv hluav taws xob uas siv los tswj thiab tiv thaiv hluav taws xob. MCBs kuj yog cov hluav taws xob hluav taws xob tab sis lawv txawv ntawm qhov uas lawv tau siv rau cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob tsawg.

MCCBs tuaj yeem siv rau thaj tsam xav tau lub zog siab, xws li kev lag luam loj.

MCBsmuaj ib lub voj voog ruaj khov thaum nyob ntawm MCCBs, lub voj voog tripping yog txav tau.

Hais txog amps, MCBs muaj tsawg dua 100 amps thaum MCCBs tuaj yeem muaj siab li 2500 amps.

Nws tsis tuaj yeem qhib thiab tawm ntawm MCB thaum nws tuaj yeem ua tau nrog MCCB los ntawm kev siv lub xov hlau shunt.

MCCBs feem ntau yog siv rau hauv cov xwm txheej uas muaj qhov hnyav tam sim no thaum MCBs tuaj yeem siv rau hauv ib qho hluav taws xob qis tam sim no.

Yog li, yog tias koj xav tau lub tshuab hluav taws xob rau koj lub tsev, koj yuav siv MCB tab sis yog tias koj xav tau ib qho chaw rau kev lag luam, koj yuav siv MCCB.
