Kev Nkag SiabMCCBthiabMCBCov Kev Txawv Tseem Ceeb thiab Cov Ntawv Thov

Hauv kev ua haujlwm ntawm kev tsim hluav taws xob thiab kev tiv thaiv hluav taws xob, ob lo lus feem ntau siv: MCB (miniature circuit breaker) thiab MCCB (molded case circuit breaker). Ob lub cuab yeej ua lub luag haujlwm tseem ceeb ntawm kev tiv thaiv cov circuits los ntawm kev overloads thiab luv circuits, tab sis lawv txawv ntau hauv lawv txoj kev tsim, kev siv, thiab kev ua haujlwm. Tsab xov xwm no lub hom phiaj yog los piav qhia qhov txawv ntawm MCBs thiab MCCBs, pab koj nkag siab thaum twg thiab vim li cas siv txhua yam.

MCB yog dab tsi?

Lub tshuab hluav taws xob me me (MCB) yog ib lub cuab yeej me me uas siv los tiv thaiv cov hluav taws xob los ntawm kev thauj khoom ntau dhau thiab luv luv. MCB feem ntau siv rau hauv cov ntawv thov hauv tsev thiab kev lag luam nrog cov ntsuas tam sim no qis, feem ntau yog txij li 0.5A txog 125A. Thaum tam sim no tshaj qhov tau teem tseg, MCB yuav txiav tawm, tiv thaiv kev puas tsuaj rau lub voj voog thiab cov khoom siv txuas nrog.

Cov cuab yeej hluav taws xob me me (MCBs) teb sai sai, uas yog qhov tseem ceeb rau kev txo qhov kev puas tsuaj los ntawm qhov ua yuam kev. Lawv kuj tseem tuaj yeem rov teeb tsa dua, txhais tau tias thaum qhov ua yuam kev tau daws lawm, MCB tuaj yeem rov teeb tsa dua tau yooj yim yam tsis tas hloov. Qhov no ua rau MCBs yog qhov kev xaiv nrov rau kev tiv thaiv cov teeb pom kev zoo, cov qhov hluav taws xob, thiab cov khoom siv me me.

MCCB yog dab tsi?

Cov Moulded case circuit breakers (MCCBs), ntawm qhov tod tes, muaj zog dua thiab tsim los rau kev siv tam sim no siab dua, feem ntau yog txij li 100A txog 2500A. MCCBs feem ntau siv rau hauv kev lag luam thiab kev lag luam uas muaj cov khoom siv hluav taws xob hnyav. Lawv muab kev tiv thaiv overload, short-circuit, thiab ground-fault, ua rau lawv haum rau ntau yam kev siv.

Cov khoom siv hluav taws xob uas muaj pwm (MCCBs) muaj cov chaw teeb tsa uas hloov kho tau, uas tso cai rau cov neeg siv kho qib kev tiv thaiv rau cov kev xav tau tshwj xeeb ntawm lub tshuab hluav taws xob. Qhov no muaj txiaj ntsig zoo rau cov chaw ua haujlwm uas cov khoom siv tam sim no xav tau yuav txawv. MCCBs feem ntau kuj muaj cov yam ntxwv siab heev xws li kev saib xyuas deb thiab kev sib txuas lus, txhim kho lawv cov haujlwm hauv cov tshuab hluav taws xob nyuaj.

Qhov sib txawv tseem ceeb ntawm MCB thiab MCCB

1. Qhov Ntsuas Tam Sim No**: Qhov sib txawv tseem ceeb tshaj plaws ntawm MCB thiab MCCB yog lawv qhov ntsuas tam sim no. MCB tsim nyog rau cov ntawv thov tam sim no qis dua (txog li 125A), thaum MCCB tsim nyog rau cov kev xav tau tam sim no siab dua (100A txog 2500A).

2. Kev Kho Tau: MCBs muaj qhov chaw teeb tsa ruaj khov, thaum MCCBs muab cov chaw teeb tsa kho tau, ua rau muaj kev ywj pheej ntau dua hauv kev tiv thaiv lub voj voog.

3. Daim Ntawv Thov: MCBs feem ntau yog siv rau hauv kev siv hauv tsev thiab kev lag luam me, thaum MCCBs yog tsim los rau kev siv hauv kev lag luam thiab kev lag luam hnyav, uas cuam tshuam nrog cov khoom loj dua thiab cov txheej txheem nyuaj dua.

4. Qhov Loj thiab Tsim: Cov khoom siv hluav taws xob me me (MCBs) feem ntau me dua thiab me dua li cov khoom siv hluav taws xob molded case (MCCBs), ua rau lawv yooj yim dua rau kev teeb tsa hauv qhov chaw tsawg. Cov khoom siv hluav taws xob molded case (MCCBs) loj dua, xav tau chaw ntau dua, thiab feem ntau yog teeb tsa hauv cov khoom sib dhos switchgear.

5. Tus nqi: Cov khoom siv hluav taws xob me me (MCBs) feem ntau pheej yig dua li cov khoom siv hluav taws xob molded case circuit breakers (MCCBs), ua rau lawv yog cov kev daws teeb meem pheej yig rau cov ntawv thov me me. Txawm li cas los xij, lawv cov kev ua haujlwm thiab kev ua tau zoo dua ua rau lawv tsim nyog rau kev nqis peev hauv cov chaw loj dua thiab xav tau ntau dua.

Hauv kev xaus lus

Hauv kev xaus lus, cov khoom siv hluav taws xob me me (MCBs) thiab cov khoom siv hluav taws xob molded case (MCCBs) ob leeg ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws xob, tab sis lawv cov ntawv thov thiab peev xwm sib txawv heev. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv cov cuab yeej zoo rau koj cov kev xav tau tshwj xeeb. Txawm hais tias koj tab tom tiv thaiv lub voj voog me me hauv tsev lossis lub kaw lus lag luam loj, kev xaiv lub tshuab hluav taws xob zoo ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm zoo ntawm koj cov khoom siv hluav taws xob. Ib txwm sab laj nrog tus kws hluav taws xob lossis tus kws ua hluav taws xob kom txiav txim siab qhov kev daws teeb meem zoo tshaj plaws rau koj qhov xwm txheej tshwj xeeb.
