I-Molded Case Circuit Breakers
A i-mold case circuit breaker (MCCB)luhlobo lwesiphambano sesiphaluka esisetyenziselwa ukukhuselwa kombane kwiindawo zoshishino kunye nezorhwebo ngenxa yokukwazi ukubonelela ngokhuseleko oluthembekileyo nolukhuselekileyo ngokubhekiselele kwi-overcurrent, i-short circuits kunye nezinye iimpazamo zombane.Kweli nqaku, siza kujonga nzuluIi-MCCBskwaye baxoxe ngeempawu zabo, imigaqo yokusebenza, ukwakhiwa, kunye nokusetyenziswa.
Iimpawu zee-MCCBs
Ii-MCCBs ziyilwe zinemisebenzi emininzi enceda ukukhusela iinkqubo zombane ngendlela ekhuselekileyo nethembekileyo.Ezinye iimpawu eziphambili ze-MCCB ziquka:
- Umthamo omkhulu wokwaphuka:I-molded case circuit breakersziyakwazi ukwaphula imisinga ukuya kumawaka ee-ampere, zizenze zilungele usetyenziso lwamandla aphezulu.
- Indlela yohambo lwe-Thermal-magnetic:I-molded case circuit breakerssebenzisa indlela yohambo lwe-thermal-magnetic ukuze ukhangele kwaye uphendule kwi-overcurrent kunye neesekethe ezimfutshane.Izinto zohambo lwe-Thermal ziphendula kumthwalo ogqithisileyo, ngelixa izinto zohambo lwemagnethi ziphendula kwiisekethe ezimfutshane.
- Ukusetwa kohambo oluhlengahlengiswayo: I-MCCBs inesetingi yohambo oluhlengahlengiswayo, oluvumela ukuba lubekwe kwinqanaba elifanelekileyo lesicelo esifunwayo.
- Uluhlu olubanzi lweesayizi zesakhelo: Ii-MCCBs zifumaneka kwiintlobo ezahlukeneyo zobukhulu besakhelo, ezivumela ukuba zisetyenziswe kwizinto ezahlukeneyo. .Into yohambo lwe-thermal ibona ubushushu obuveliswa kukuhamba kwangoku kwisekethe kwaye ihambisa isaphuli sesekethe xa umsinga udlula umlinganiselo wohambo.Isiqalelo sohambo lwemagnethi siva umhlaba wemagnethi oveliswe yisekethe emfutshane kwisekethe, ikhubekisa isaphuli sesekethe ngokukhawuleza.
- I-MCCB iqulathe indlu yeplastiki ebunjiweyo egcina indlela yohambo, abafowunelwa kunye neendawo zokuthwala zangoku.
- Abafowunelwa benziwe ngezinto ezisebenza kakhulu ezifana nobhedu, ngelixa indlela yohambo ibandakanya umtya we-bimetallic kunye nekhoyili yamagnetic.
Ukusetyenziswa kwe-MCCB
Ii-MCCBs ziqhele ukusetyenziswa kwizicelo ezahlukeneyo ezinje:
- Inkqubo yokuhambisa amandla
- Iziko loLawulo lweeMoto
- Oomatshini bemizi-mveliso
- Iinguqu
- Iseti yejenereyitha
ukuququmbela
Ii-breakers zesekethe ezibunjiweyo zithembeke kakhulu kwaye zisebenza izixhobo zokukhusela umbane.Ukwakhiwa kunye neempawu zabo zibenza balungele ukusetyenziswa kwizicelo ezahlukeneyo ezifana neziguquli, iinkqubo zokuhambisa amandla, kunye namaziko okulawula iimoto.Indlela yabo yohambo lwe-thermal-magnetic uhambo, umthamo ophezulu wokwaphuka kunye nesetingi zohambo ezilungelelanisiweyo zibenza babe lukhetho oludumileyo lokhuseleko lombane kwiindawo zorhwebo nakwimizi-mveliso.
