Moulded case Circuit Breakers yog cov khoom siv tiv thaiv hluav taws xob uas tsim los tiv thaiv hluav taws xob hluav taws xob los ntawm cov hluav taws xob ntau dhau.Qhov hluav taws xob ntau dhau no tuaj yeem tshwm sim vim yog overload lossis luv luv Circuit Court.Cov ntaub ntawv molded Circuit Court breakers tuaj yeem siv dav hauv ntau qhov voltages thiab zaus nrog lub ntsiab lus qis thiab sab sauv ntawm kev hloov pauv mus txawv tebchaws.Ntxiv nrog rau cov txheej txheem tripping, MCCBs kuj tuaj yeem siv los ua kev sib txuas ntawm phau ntawv hloov thaum muaj xwm txheej ceev lossis kev saib xyuas haujlwm.MCCBs yog tus qauv tsim thiab kuaj rau overcurrent, voltage surge, thiab kev tiv thaiv txhaum cai kom muaj kev nyab xeeb hauv txhua qhov chaw thiab kev siv.Lawv ua haujlwm tau zoo raws li kev hloov pauv rau lub voj voog hluav taws xob kom tshem tawm cov hluav taws xob thiab txo qis kev puas tsuaj los ntawm Circuit Court overload, txhaum hauv av, luv circuits, lossis thaum tam sim no tshaj qhov txwv tam sim no.
MCCB los yog fuse yog ib qho hluav taws xob feem ntau siv hauv kev lag luam los tiv thaiv cov khoom siv hluav taws xob thiab tshuab.Hauv lub neej niaj hnub, MCCB tau siv dav.Qee daim ntawv thov MCCB feem ntau tau piav qhia hauv qab no.
1.Kev faib hluav taws xob: MCCB tuaj yeem pab cov neeg teeb tsa faib cov phiaj xwm rau cov khoom siv hluav taws xob sib txawv.Los ntawm MCCB, cov neeg siv tuaj yeem tswj hwm kev faib hluav taws xob thiab qhov tam sim no ntawm txhua lub cuab yeej.
2.Short circuit tiv thaiv: Lub luag haujlwm tseem ceeb ntawm MCCB yog txiav tawm ntawm Circuit Court thaum muaj kev cuam tshuam luv luv.Qhov no tiv thaiv cov cuab yeej puas tsuaj, tso tawm cov khoom txaus ntshai xws li hluav taws.
3.Overload tiv thaiv: Zoo ib yam li kev tiv thaiv luv luv, MCCB kuj tuaj yeem tiv thaiv cov khoom siv los ntawm overloaded.Qhov no tuaj yeem ua tiav los ntawm kev teeb tsa hluav taws xob hluav taws xob kom tsis txhob muaj hluav taws xob puas tsuaj los ntawm cov khoom siv ntau dhau.
4.Generator tiv thaiv: MCCB yog dav siv hauv kev tshawb nrhiav thiab kev tiv thaiv cov tshuab hluav taws xob loj.Nws tuaj yeem saib xyuas qhov kev ua haujlwm ib txwm muaj ntawm lub tshuab hluav taws xob, kuaj pom cov teeb meem thiab qhib lub tshuab hluav taws xob tiv thaiv hluav taws xob.
5.Power transformer tiv thaiv: MCCB tuaj yeem tiv thaiv lub transformer los ntawm overloading thiab saib xyuas lub transformer over-temperature nyob rau tib lub sij hawm.
6.Movable lub tog raj kheej tiv thaiv: MCCB yog dav siv hauv pob zeb, cement thiab ntxhia crushers.Nws pom cov luv luv Circuit Court thiab overloads ntawm cov cuab yeej, yog li tiv thaiv cov cuab yeej los ntawm kev puas tsuaj.
Hauv kev xaus, MCCBs tau siv dav thiab ua lub luag haujlwm tseem ceeb hauv ntau yam hluav taws xob thiab tshuab.Thaum xaiv MCCB, ntau yam tshwj xeeb yuav tsum tau ua tib zoo txiav txim siab txhawm rau ua kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm lub kaw lus, suav nrog lub peev xwm nqa tam sim no, kev ua haujlwm zoo, thaj chaw siv tau, thiab lwm yam tseem ceeb.
