Umehluko kanye Nokusetshenziswa Phakathi kwe-MCB ne-MCCB

UkuqondaI-MCCBfuthiI-MCBIzingxenye Eziyisisekelo Zezinhlelo Zikagesi

Emkhakheni wobunjiniyela kagesi kanye nokusatshalaliswa kwamandla, sivame ukuhlangana namagama athi “i-molded case circuit breaker (MCCB)” kanye nelithi “i-miniature circuit breaker (MCB)”. Womabili la madivayisi adlala indima ebalulekile ekuvikeleni amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane, kodwa ukusetshenziswa kwawo kanye nemiklamo yawo kuyahlukahluka. Lesi sihloko sizogxila kakhulu ezicini, imisebenzi, kanye nokusetshenziswa kwama-molded case circuit breaker (MCCB) kanye nama-miniature circuit breaker (MCB), futhi sigqamise ukubaluleka kwawo ekuqinisekiseni ukuphepha nokusebenza kahle kukagesi.

Kuyini i-MCB?

I-miniature circuit breaker (MCB) iyithuluzi elincane elenzelwe ukuvikela amasekethe kagesi ekugcwaleni ngokweqile kanye namasekethe amafushane. Ama-MCB avame ukusetshenziselwa izinjongo zokuhlala nezentengiselwano ngezilinganiso zamandla aphansi, ngokuvamile asukela ku-0.5A kuya ku-125A. Uma kutholakala iphutha, anqamula isekethe ngokuzenzakalelayo, ngaleyo ndlela avimbele ukulimala kwezinto zikagesi futhi anciphise ingozi yomlilo.

Ama-Miniature circuit breaker (ama-MCB) asebenza ngezimiso zokukhubeka kokushisa kanye nokukhubeka kukazibuthe. Indlela yokukhubeka kukushisa isetshenziselwa ukuphendula ezimweni zokulayisha ngokweqile, kuyilapho indlela yokukhubeka kukazibuthe isetshenziselwa ukuphendula ezimweni ze-short circuit. Lokhu kusebenza okubili kuqinisekisa ukuthi ama-miniature circuit breaker anganikeza isivikelo esithembekile sezinhlelo eziningi zikagesi. Ngaphezu kwalokho, ama-miniature circuit breaker kulula ukuwasetha kabusha ngemva kokukhubeka, okuyinto elula ukuyisebenzisa futhi evumela ukusebenza kahle ekusetshenzisweni kwansuku zonke.

Kuyini i-MCCB?

Ama-Molded Case Circuit Breakers (ama-MCCB) angamadivayisi aqinile avame ukukalwa kusukela ku-100A kuya ku-2500A. Ama-MCCB avame ukusetshenziswa ezindaweni zezimboni nezentengiselwano lapho imithwalo kagesi inkulu khona. Njengama-MCB, ama-MCCB avikela ekuthwaleni ngokweqile kanye nama-short circuits, kodwa anezici ezithuthuke kakhulu, okuhlanganisa izilungiselelo zokuhamba ezilungisekayo kanye nekhono lokusingatha amaza aphezulu ephutha.

Ama-Molded case circuit breakers (ama-MCCB) aqukethe isakhiwo se-molded case esigcina izingxenye zangaphakathi, esinikeza ukuqina nokuvikelwa ezicini zemvelo. Ngokuvamile afaka izici ezengeziwe njengokuvikela amaphutha omhlaba kanye namakhono okuxhumana, okuvumela ukuthi ahlanganiswe ezinhlelweni zikagesi eziyinkimbinkimbi kakhulu. Lokhu kwenza ama-MCCB afaneleke kakhulu ekusetshenzisweni kwezitshalo zokukhiqiza, izikhungo zedatha, kanye nezakhiwo ezinkulu zezentengiselwano.

Umehluko Obalulekile Phakathi kwe-MCB ne-MCCB

1. Ugesi Olinganiselwe: Umehluko obaluleke kakhulu phakathi kwe-Miniature Circuit Breaker (MCB) kanye ne-Molded Case Circuit Breaker (MCCB) ugesi wawo olinganiselwe. Ama-MCB afanelekela izinhlelo zokusebenza zamandla aphansi (kufika ku-125A), kanti ama-MCCB afanelekela izinhlelo zokusebenza zamandla aphezulu (100A kuya ku-2500A).

2. Ukusetshenziswa: Ama-MCB asetshenziswa kakhulu ezindaweni zokuhlala kanye nezindawo zokuhweba ezilula, kanti ama-MCCB aklanyelwe ukusetshenziswa kwezimboni kanye nezindawo zokuhweba ezisindayo.

3. Indlela Yokukhubeka: Ama-MCB ngokuvamile anezilungiselelo zokukhubeka ezingaguquki, kanti ama-MCCB ngokuvamile anezilungiselelo zokukhubeka ezilungisekayo, okuvumela ukwenza ngezifiso izidingo ezithile zomthwalo.

4. Usayizi Nomklamo: Ama-Miniature circuit breaker (ama-MCB) mancane futhi mancane, okwenza afaneleke kakhulu ezindaweni ezincishisiwe. Ngokuphambene nalokho, ama-molded case circuit breaker (ama-MCCB) makhulu, aqinile, futhi aklanyelwe ukusingatha imithwalo kagesi ephezulu.

5. Izindleko: Ngokuvamile, ama-MCB ashibhile kakhulu kuzinhlelo zokusebenza ezisebenzisa amandla aphansi, kuyilapho ama-MCCB evame ukubiza kakhulu ngenxa yezici zawo ezithuthukisiwe kanye nezilinganiso eziphakeme.

Ekuphetheni

Ngamafuphi, ama-MCCB nama-MCB ayizingxenye ezibalulekile ezinhlelweni zikagesi, futhi ngalinye lidlala indima ehlukile kuye ngezidingo zohlelo lokusebenza. Ukuqonda umehluko phakathi kwalawa madivayisi amabili kubalulekile ekukhetheni ikhambi lokuvikela isekethe elifanele. Kungakhathaliseki ukuthi lisetshenziselwa ukuhlala noma izimboni, ukuqinisekisa ukusetshenziswa okufanele kwama-MCCB nama-MCB kubalulekile ekugcineni ukuphepha kukagesi, ukusebenza kahle, kanye nokuthembeka. Njengoba ubuchwepheshe buqhubeka nokukhula, indima yalawa ma-circuit breaker izoqhubeka nokuba yingxenye ebalulekile yokusebenza okuphephile kwezinhlelo zikagesi emhlabeni jikelele.
