Khoom Qhia Qhia

Taw qhia:

Moulded Cov Txheej Txheem Circuit Court (MCCB) yog ib qho uas yuav tsum muaj ntawm cov hluav taws xob, muab kev tiv thaiv hluav taws xob ntau dhau los thiab cov luv luv. Feem ntau, mccbs tau muab ntsia rau hauv lub chaw faib hluav taws xob tseem ceeb ntawm lub tsev laus, tso cai rau lub kaw lus kom kaw thaum tsim nyog. McCBLs muaj ntau qhov ntau thiab tsawg thiab kev ntsuas, nyob ntawm seb qhov loj ntawm cov hluav taws xob.

Hauv phau ntawv qhia no, peb yuav them rau cov cheebtsam thiab cov yam ntxwv ntawm ib txwm McCB, lawv ua haujlwm li cas, thiab hom twg. Peb kuj yuav sib tham txog cov txiaj ntsig ntawm kev siv hom kev ua txhaum no hauv koj lub tshuab hluav taws xob.

LTS RATION RUAJ RWB THAWJ VEDFILLage yog 1000V, uas yog qhov tsim nyog hloov dua siab tshiab thiab muaj kev siv nyiaj voltage nrog 800acsdm1-800 yam tsis muaj kev tiv thaiv muaj zog).

Cov yam ntxwv tseem ceeb tshaj plaws

● Cov Circuit Court breaker muaj ntau dhau ntawm Circuit Court thiab UndervolSage tiv thaiv kev ua haujlwm, uas tuaj yeem tiv thaiv kab thiab fais fab ntawm kev puas tsuaj. Nyob rau tib lub sijhawm, nws tuaj yeem muab kev tiv thaiv indirect indirect rau tib neeg, thiab tseem tuaj yeem muab kev tiv thaiv rau kev tiv thaiv ntev los no, uas yuav ua rau hluav taws kub
● Cov Circuit Court breaker muaj cov yam ntxwv ntawm cov ntim me me, siab tawg qhov siab, kev co thiab anti luv
Circuit Court breaker tuaj yeem muab tau kaw kab ntsug thiab kab rov tav
Tus neeg ua txhaum Circuit Court tsis tuaj yeem hloov pauv hauv, uas yog, tsuas yog 1, 3 thiab 5 tau tso cai ua lub zog sib tw, thiab 6 thiab 6
Racler Breaker tuaj yeem muab faib ua ntej xaim, rov qab wiring thiab ntsaws cov hlau

MCCB yog dab tsi?

McCB yog daim foos luv luv rau cov khoom siv hluav taws xob ua ke. Nws yog ib qho piv txwv ntawm cov khoom siv hluav taws xob hluav taws xob uas muaj ntau dua li tsis siv thaum lub nra tam sim no tau ntau dua li qhov kev txwv ntawm cov me me Circuit Court breaker.

MCCB muaj kev tiv thaiv tawm tsam cov kev ua txhaum luv luv thiab tseem siv rau kev hloov cov voj voog. Nws tuaj yeem ua haujlwm rau cov kev ntsuas tam sim no ntxiv nrog rau qib kev ua txhaum, nyob rau hauv cov xwm txheej ntawm ob peb lub hom phiaj hauv tsev. Qhov kev ntsuas dav dav thiab kev kub siab ntau hauv pwm hluav taws xob Circuit Court breaker txhais tau tias lawv txawm haum rau kev lag luam.

McCB ua haujlwm li cas?

MCCB siv ib lub cuab yeej kub rhiab (lub thermal caij) nrog cov khoom siv hluav taws xob tam sim no (lub caij sib nqus) los muab cov phiaj xwm kev mus ncig ua si rau kev tiv thaiv thiab rho tawm. Qhov no ua rau MCCB los muab:

Kev tiv thaiv ntau dhau,

Hluav taws xob ua txhaum tiv thaiv kab mob luv luv, thiab

Hluav taws xob mus rau kev sib txuas.

Qhov sib txawv ntawm MCB thiab McCB yog dab tsi?

MCB thiab McCB feem ntau siv cov khoom siv sib cog lus Circuit Txwv. Cov cuab yeej siv no muab kev tiv thaiv tawm tsam tam sim no thiab luv luv. Muaj qee qhov sib txawv ntawm ob cov khoom siv no ntxiv rau lub peev xwm uas muaj peev xwm tam sim no. Lub peev xwm tam sim no muaj peev xwm ntawm MCB feem ntau yog 125A, thiab MCCB muaj nyob ntawm kev ntaus nqi ntawm2500a.
