Miniature Circuit Breakers (MCBs) thiab molded case circuit breakers (MCCBs) yog ob qho tib si tseem ceeb hauv cov tshuab hluav taws xob siv los tiv thaiv overloads, luv Circuit Court, thiab lwm yam txhaum. Txawm hais tias lub hom phiaj zoo sib xws, tseem muaj qee qhov sib txawv ntawm ob qho tib si ntawm kev muaj peev xwm, cov yam ntxwv ntawm kev sib tw, thiab kev tawg lub peev xwm.

Miniature Circuit Breaker (MCB)

A Miniature Circuit Breaker (MCB)yog ib qho khoom siv hluav taws xob compact siv los tiv thaiv circuits ntawm luv luv circuits thiab overloads. Nws yog feem ntau siv rau hauv kev teeb tsa hluav taws xob hauv cov tsev nyob thiab kev lag luam thiab yog tsim los tiv thaiv ib tus neeg circuits es tsis yog tag nrho cov tshuab hluav taws xob.

Moulded case Circuit Breaker (MCCB)

A Moulded Case Circuit Breaker (MCCB)yog qhov loj dua, muaj zog dua Circuit Court breaker uas tseem siv los tiv thaiv circuits los ntawm luv luv circuits, overloads, thiab lwm yam txhaum. MCCBs yog tsim los rau siab dua voltage thiab tam sim no kev ntaus nqi rau kev lag luam, kev lag luam thiab kev siv vaj tse loj.

Qhov txawv ntawm MCCB thiab MCB

Qauv:MCBs yog me me dua li MCCBs. Lub MCB muaj ib tug bimetallic strip uas khoov thaum lub sij hawm tam sim no tshaj ib tug tej yam pib, ua rau lub MCB thiab qhib lub Circuit Court. Tab sis cov qauv ntawm MCCB yog qhov nyuaj dua. Lub tshuab electromagnetic yog siv los ua rau lub voj voog thaum lub sijhawm tam sim no dhau ntawm qhov chaw pib. Tsis tas li ntawd, MCCB muaj thermal magnetic tiv thaiv los tiv thaiv overload thiab luv circuits.

Muaj peev xwm:MCBs feem ntau yog siv rau qis tam sim no thiab qhov ntsuas hluav taws xob hauv cov tsev nyob thiab kev lag luam. Feem ntau mus txog 1000V thiab nrog kev ntsuas ntawm 0.5A thiab 125A. MCCBs yog tsim los rau kev lag luam thiab kev lag luam loj thiab muaj peev xwm tswj tau tam sim no ntawm 10 amps txog 2,500 amps.

Breaking Peev Xwm:Lub peev xwm tawg yog qhov siab tshaj plaws ntawm qhov txhaum tam sim no lub Circuit Court breaker tuaj yeem mus yam tsis muaj kev puas tsuaj. Piv nrog rau MCB, MCCB muaj peev xwm tawg ntau dua. MCCBs tuaj yeem cuam tshuam txog 100 kA, thaum MCBs muaj peev xwm cuam tshuam 10 kA lossis tsawg dua. Yog li, MCCB yog qhov tsim nyog rau cov ntawv thov uas muaj peev xwm tawg siab.

Tripping yam ntxwv:Qhov kom zoo dua ntawm MCCB thiab MCB yog qhov kev hloov pauv mus txawv tebchaws. MCCB tso cai rau tus kheej hloov pauv ntawm qhov kev mus ncig tam sim no thiab lub sijhawm ncua sijhawm rau kev tiv thaiv hluav taws xob ntau dua thiab cov khoom siv. Hauv qhov sib piv, MCBs tau kho qhov chaw mus txawv tebchaws thiab feem ntau yog tsim los mus ncig ntawm tus nqi tam sim no.

Tus nqi:MCCBs feem ntau yuav kim dua li MCBs vim lawv qhov loj me, kev ua haujlwm zoo, thiab lwm yam. MCCBs feem ntau muaj peev xwm ntau dua thiab hloov tau mus txawv tebchaws. MCBs feem ntau yog qhov kev xaiv qis dua rau kev tiv thaiv cov tshuab hluav taws xob me thiab khoom siv.

Xaus

Hauv cov ntsiab lus, MCCBs thiab MCBs ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv circuits los ntawm luv luv circuits, overloads, thiab lwm yam tsis zoo hauv cov tshuab hluav taws xob. Txawm hais tias lub luag haujlwm lossis lub hom phiaj ntawm ob qhov zoo sib xws, tseem muaj qhov sib txawv ntawm daim ntawv thov. MCCBs zoo dua rau cov tshuab hluav taws xob loj nrog cov kev xav tau siab tam sim no, thaum MCBs tau txais txiaj ntsig zoo dua thiab zoo dua rau kev tiv thaiv cov tshuab hluav taws xob me thiab khoom siv. Paub txog cov kev sib txawv no yuav pab koj xaiv lub Circuit Court breaker rau koj cov kev xav tau tshwj xeeb thiab xyuas kom koj cov hluav taws xob muaj kev nyab xeeb thiab siv tau zoo.
