Qhov txawv ntawm MCB thiab MCCB

Thaum nws los txog rau cov circuit breakers, ob qho kev xaiv uas siv ntau yog MCB thiab MCCB. Txawm hais tias lawv ob leeg siv los tiv thaiv cov kab ke hluav taws xob los ntawm kev thauj khoom ntau dhau thiab luv luv circuits, muaj qee qhov sib txawv tseem ceeb ntawm ob yam khoom.

Lub tshuab hluav taws xob me me (MCB), raws li lub npe qhia, yog lub tshuab hluav taws xob me me uas muaj ntau yam haujlwm. Siv dav hauv ntau qhov chaw xws li kev lag luam, kev lag luam, cov tsev siab, thiab cov tsev nyob. MCBs yog tsim los muab kev tiv thaiv rau cov chaw faib hluav taws xob hauv cov tsev. Muaj ntau hom thiab ntau npaum li cas ntawm cov khoom siv hluav taws xob, tsim nyog rau ntau yam kev siv.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm MCB yog nws lub peev xwm los tswj ntau yam kev ntsuas hluav taws xob. Nws yog qhov tsim nyog rau kev tiv thaiv overload thiab luv luv ntawm cov kab nrog AC 50/60Hz rated voltage 230/400V thiab rated tam sim no txog li 63A. Tsis tas li ntawd, cov circuit breakers me me kuj tseem siv tau rau kev ua haujlwm tsis tshua muaj kev hloov pauv ntawm cov kab hauv qab qhov xwm txheej ib txwm muaj. Qhov kev hloov pauv no ua rau lawv zoo tagnrho rau ntau lub tshuab hluav taws xob.

Nyob rau sab tes tod,cov khoom siv hluav taws xob molded (MCCB) feem ntau yog siv rau hauv cov kab ke faib hluav taws xob qis thiab cov voj voog tiv thaiv lub cev muaj zog. Nws muab kev tiv thaiv overload thiab luv luv. Lub ntsiab lus tseem ceeb ntawm MCCB yog nws lub plhaub yas, uas ua haujlwm ua lub rwb thaiv tsev thiab cais cov neeg hlau thiab cov khoom hlau uas tau cog rau hauv av. Vim nws qhov kev ntseeg tau thiab kev ruaj khov, cov khoom siv hluav taws xob molded case tau siv dav hauv ntau yam lag luam.

Txawm hais tias MCB thiab MCCB yog cov khoom siv hluav taws xob sib txuas, muaj qee qhov sib txawv tseem ceeb ntawm lawv. Ua ntej, lawv muaj cov yam ntxwv hluav taws xob thiab tshuab sib txawv. MCB yog qhov tsim nyog rau cov xov hlau txog li 10 square meters, thaum MCCB tuaj yeem txuas cov xov hlau tuab dua, xws li cov xov hlau saum toj no 35 square meters. Qhov no ua rau MCCB tuaj yeem tswj tau cov peev xwm siab dua thiab cov hluav taws xob tam sim no.

Lwm qhov txawv yog lawv txuas li cas. Cov terminals ntawm lub molded case circuit breaker txuas nrog cov txiv ntoo, uas tuaj yeem nias tau yooj yim thiab xyuas kom meej tias muaj kev sib cuag zoo. Qhov sib piv, MCBs siv cov terminals me me uas tsuas yog tuaj yeem nruj nrog lub screwdriver. Qhov sib txawv ntawm cov txheej txheem txuas no cuam tshuam rau kev sib txuas thiab kev sib cuag zoo.

Ntxiv mus, MCB thiab MCCB muaj cov chaw ua haujlwm sib txawv. MCBs yog tsim los rau ntau yam kev siv, ua rau lawv haum rau kev siv hauv ntau qhov chaw sib txawv. MCCB, ntawm qhov tod tes, feem ntau yog siv rau hauv cov ntawv thov hloov pauv me me.

Hauv kev xaus, thaum cov khoom siv hluav taws xob me me thiab cov khoom siv hluav taws xob molded case circuit breakers ob leeg siv los tiv thaiv cov kab ke hluav taws xob, lawv muaj qee qhov sib txawv tseem ceeb. MCB siv dav thiab muaj ntau yam kev siv, thaum MCCB feem ntau siv rau hauv cov kab ke faib hluav taws xob qis thiab cov voj voog tiv thaiv lub cev muaj zog. Lawv sib txawv hauv cov yam ntxwv hluav taws xob thiab cov khoom siv kho tshuab, cov txheej txheem txuas thiab ib puag ncig ua haujlwm. Kev nkag siab txog qhov sib txawv no yuav pab txiav txim siab seb lub tshuab hluav taws xob twg zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb.
