Intshayelelo:

I-Molded Case Circuit Breakers (MCCB) yinxalenye efunekayo yeenkqubo zombane, ezibonelela ngokhuseleko lomthwalo ogqithisiweyo kunye nokhuseleko olufutshane.Kwiimeko ezininzi, ii-MCCBs zifakwe kwibhodi yokuhambisa amandla engundoqo kwiziko, ukuvumela inkqubo ukuba ivalwe ngokulula xa kuyimfuneko.Ii-MCCB zifumaneka ngokobukhulu obahlukeneyo kunye nokulinganisa, kuxhomekeke kubungakanani benkqubo yombane.

Kwesi sikhokelo, siza kugubungela amacandelo kunye neempawu ze-MCCB eqhelekileyo, indlela esebenza ngayo, kwaye zeziphi iintlobo ezikhoyo.Siza kuxoxa kwakhona ngeenzuzo zokusebenzisa olu hlobo lwesaphuli kwinkqubo yakho yombane.

I-lts ilinganiswe i-voltage ye-insulation yi-1000V, elungele ukuguqulwa okungaqhelekanga kunye ne-motor eqala kwiisekethe ezine-AC 50 Hz, i-voltage yokusebenza irethiwe ukuya kwi-690V kwaye ilinganiswe ngoku ukuya kuthi ga kwi-800ACSDM1-800 ngaphandle kokhuseleko lwemoto).

Ezona mpawu zibalulekileyo

● I-breaker circuit ine-overload, isiphaluka esifutshane kunye nemisebenzi yokukhusela i-undervoltage, enokukhusela umgca kunye nezixhobo zamandla kumonakalo.Kwangaxeshanye, inokubonelela ngokhuseleko lonxibelelwano olungathanga ngqo kubantu, kwaye inokubonelela ngokhuseleko lwempazamo yexesha elide elingenakubonwa ngokukhuselwa kwangoku, okunokubangela ingozi yomlilo.
● I-breaker circuit ineempawu zomthamo omncinci, ukuphakama okuphezulu kokuphuka, i-arcing emfutshane kunye ne-anti vibration
● I-breaker circuit inokufakwa ngokuthe tye kunye ne-horizontal
● I-circuit breaker ayikwazi ukutshintshelwa ngaphakathi, oko kukuthi, kuphela i-1, i-3 kunye ne-5 kuphela evumelekileyo njengeetheminali zamandla, kunye ne-2, 4 kunye ne-6 ziitheminali zokulayisha.
● I-breaker circuit inokwahlulwa ibe yi-wiring yangaphambili, i-wiring yangasemva kunye ne-plug-in wiring

Yintoni i-MCCB?

I-MCCB yifom emfutshane ye-Molded Case Circuit Breaker.Kungumzekelo oqhelekileyo wesixhobo sokhuseleko sombane esisoloko sisetyenziswa xa umthwalo wangoku uphezulu kakhulu kunomda we-miniature breaker circuit.

I-MCCB ibonelela ngokhuseleko kwiimpazamo zesekethe ezimfutshane kwaye isetyenziselwa ukutshintsha iisekethe.Ingasetyenziselwa ukulinganisa okuphezulu kwangoku kunye nenqanaba lesiphoso, kwimeko yeenjongo ezimbalwa zasekhaya.Ukulinganiswa okubanzi kwangoku kunye nomthamo ophezulu wokuqhawula kwi-Molded Case Circuit Breaker kuthetha ukuba zifanelekile ngenxa yezizathu zoshishino.

Isebenza njani i-MCCB?

I-MCCB isebenzisa isixhobo esibuthathaka kwiqondo lobushushu (isixhobo sobushushu) esinesixhobo sangoku esinovakalelo lwe-electromagnetic (isiqalelo sombane) ukunika indlela yohambo yokhuseleko neenjongo zokuzahlula.Oku kwenza ukuba i-MCCB ibonelele:

uKhuseleko lomthwalo ogqithisileyo,

Ukukhuselwa kweFault yoMbane ngokuchasene nemisinga yesekethe emfutshane, kunye

Ukutshintsha koMbane ukuze kuqhawulwe.

Yintoni umahluko phakathi kwe-MCB ne-MCCB?

I-MCB kunye ne-MCCB zisetyenziswa ngokuqhelekileyo izixhobo zokukhusela isiphaluka.Ezi zixhobo zibonelela ngokhuseleko kwiisekethe zangoku kunye nezifutshane.Kukho iiyantlukwano ezimbalwa phakathi kwezi zixhobo zibini ngaphandle komthamo wangoku othengisiweyo.Umthamo olinganisiweyo wangoku we-MCB uqhelekile ngaphantsi kwe-125A, kwaye i-MCCB iyafumaneka ukuya kuthi ga kwi-rating ye-2500A.
