Taw qhia:
Moulded Case Circuit Breakers (MCCB) yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, muab kev tiv thaiv overload thiab tiv thaiv luv luv.Feem ntau, MCCBs tau nruab rau hauv lub rooj tsav xwm loj ntawm lub chaw faib hluav taws xob, tso cai rau lub kaw lus yooj yim kaw thaum tsim nyog.MCCBs muaj nyob rau hauv ntau qhov ntau thiab tsawg, nyob ntawm qhov loj ntawm cov hluav taws xob.
Hauv phau ntawv qhia no, peb yuav hais txog cov khoom thiab cov yam ntxwv ntawm MCCB, lawv ua haujlwm li cas, thiab hom twg muaj.Peb kuj tseem yuav tham txog cov txiaj ntsig ntawm kev siv hom breaker hauv koj lub tshuab hluav taws xob.
lts rated rwb thaiv tsev voltage yog 1000V, uas yog tsim rau infrequent conversion thiab lub cev muaj zog pib nyob rau hauv circuits nrog AC 50 Hz, rated ua hauj lwm voltage mus txog 690V thiab rated tam sim no mus txog 800ACSDM1-800 tsis muaj kev tiv thaiv lub cev muaj zog).

Cov yam ntxwv tseem ceeb tshaj plaws
● Lub Circuit Court breaker muaj overload, luv Circuit Court thiab undervoltage tiv thaiv kev ua haujlwm, uas tuaj yeem tiv thaiv kab thiab cov khoom siv hluav taws xob los ntawm kev puas tsuaj.Nyob rau tib lub sijhawm, nws tuaj yeem muab kev tiv thaiv kev tiv thaiv tsis ncaj rau tib neeg, thiab tseem tuaj yeem muab kev tiv thaiv kev ua txhaum hauv av mus ntev uas tsis tuaj yeem tshawb pom los ntawm kev tiv thaiv dhau tam sim no, uas yuav ua rau muaj kev phom sij rau hluav taws.
● Lub Circuit Court breaker muaj cov yam ntxwv ntawm lub ntim me me, siab tawg qhov siab, luv arcing thiab tiv thaiv kev co
● Lub Circuit Court breaker tuaj yeem ntsia tau ntsug thiab kab rov tav
● Lub Circuit Court breaker tsis tuaj yeem hloov mus rau hauv, uas yog, tsuas yog 1, 3 thiab 5 tau tso cai raws li lub zog hluav taws xob, thiab 2, 4 thiab 6 yog cov khoom thauj khoom.
● Lub Circuit Court breaker tuaj yeem muab faib ua cov xaim pem hauv ntej, rov qab xaim thiab txuas txuas txuas

MCCB yog dab tsi?
MCCB yog ib daim ntawv luv luv rau Moulded Case Circuit Breaker.Nws yog ib qho piv txwv ntawm cov cuab yeej hluav taws xob kev nyab xeeb uas feem ntau tsis siv thaum lub sijhawm thauj khoom tam sim no ntau dua li qhov kev txwv ntawm lub tshuab hluav taws xob me me.
MCCB muaj kev tiv thaiv luv luv Circuit Court txhaum thiab txawm siv los hloov cov circuits.Nws tuaj yeem ua haujlwm rau kev ntsuas tam sim no siab dua nrog rau qib kev ua txhaum, nyob rau hauv rooj plaub ntawm ob peb lub hom phiaj hauv tsev.Kev ntsuas tam sim no dav thiab muaj peev xwm tawg siab hauv Moulded Case Circuit Breaker txhais tau tias lawv txawm tsim nyog rau kev lag luam.
MCCB ua haujlwm li cas?
MCCB siv lub ntsuas kub rhiab heev (cov khoom siv thermal) nrog cov khoom siv hluav taws xob tam sim no (cov khoom sib nqus) los muab cov txheej txheem mus txawv tebchaws rau kev tiv thaiv thiab kev sib cais.Qhov no ua rau MCCB muab:
Kev tiv thaiv overload,
Hluav taws xob tiv thaiv tiv thaiv luv luv tam sim no, thiab
Hluav taws xob hloov rau disconnection.
Qhov txawv ntawm MCB thiab MCCB yog dab tsi?
MCB thiab MCCB feem ntau siv cov khoom siv tiv thaiv hluav taws xob.Cov cuab yeej no muab kev tiv thaiv dhau tam sim no thiab luv luv circuits.Muaj ob peb qhov sib txawv ntawm ob lub cuab yeej no ntxiv rau qhov ntsuas tam sim no.Tam sim no rated peev ntawm MCB feem ntau nyob rau hauv 125A, thiab MCCB muaj nyob rau ntawm qhov ntsuas ntawm 2500A.
