Imisebenzi kanye nomehluko phakathi kwe-MCB kanye ne-MCCB

UkuqondaI-MCCBfuthiI-MCBUmehluko Omkhulu kanye Nezicelo

Emikhakheni yobunjiniyela kagesi kanye nokuvikelwa kwesekethe, amagama amabili avame ukusetshenziswa: i-MCB (i-miniature circuit breaker) kanye ne-MCCB (i-molded case circuit breaker). Womabili la madivayisi enza umsebenzi obalulekile wokuvikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane, kodwa ahluke kakhulu ekwakhiweni kwawo, ekusetshenzisweni kwawo, kanye namakhono okusebenza. Lesi sihloko sihlose ukucacisa umehluko phakathi kwama-MCB nama-MCCB, sikusize uqonde ukuthi nini futhi kungani kufanele usebenzise ngalinye.

Kuyini i-MCB?

I-miniature circuit breaker (MCB) iyithuluzi elincane elisetshenziselwa ukuvikela amasekethe kagesi ekuthwaleni ngokweqile kanye namasekethe amafushane. Ama-MCB avame ukusetshenziswa ezindaweni zokuhlala nezentengiselwano ezinezilinganiso zamandla aphansi, ngokuvamile asukela ku-0.5A kuya ku-125A. Uma amandla adlula izinga elinqunyiwe, i-MCB iyakhubeka ngokuzenzakalelayo, ivimbele umonakalo ongaba khona kusekethe kanye nemishini exhunyiwe.

Ama-Miniature circuit breaker (ama-MCB) anikeza izikhathi zokuphendula okusheshayo, okubalulekile ekunciphiseni umonakalo obangelwa amaphutha. Aphinde aphinde asetshenziswe, okusho ukuthi uma iphutha seliphelile, i-MCB ingaphinde isethwe kabusha kalula ngaphandle kokushintshwa. Lesi sici senza ama-MCB abe ukukhetha okuthandwayo kokuvikela amasekethe okukhanyisa, izindawo zikagesi, kanye nezinto zikagesi ezincane.

Kuyini i-MCCB?

Ngakolunye uhlangothi, ama-Molded case circuit breakers (ama-MCCB) aqinile futhi aklanyelwe ukusetshenziswa kwamandla kagesi aphezulu, ngokuvamile asukela ku-100A kuya ku-2500A. Ama-MCCB avame ukusetshenziswa ezindaweni zezimboni nezentengiselwano ezinemithwalo kagesi esindayo. Ahlinzeka ngokuvikelwa kokulayisha ngokweqile, ukujikeleza okufushane, kanye nokwephulwa komhlaba, okwenza afaneleke ezinhlelweni eziningi ezahlukene.

Ama-Molded case circuit breakers (ama-MCCB) afaka izilungiselelo zokuhamba ezilungisekayo, okuvumela abasebenzisi ukuthi bahlele izinga lokuvikelwa ngokwezidingo ezithile zesistimu kagesi. Lesi sici siwusizo ikakhulukazi ezindaweni zezimboni lapho izidingo zamanje zemishini zingahluka khona. Ama-MCCB avame ukufaka izici ezithuthukisiwe njengokuqapha okude kanye nokuxhumana, okuthuthukisa ukusebenza kwawo ezinhlelweni zikagesi eziyinkimbinkimbi.

Umehluko obalulekile phakathi kwe-MCB ne-MCCB

1. Isilinganiso Samanje**: Umehluko obaluleke kakhulu phakathi kwe-MCB ne-MCCB yisilinganiso sabo samanje. I-MCB ifaneleka kuzinhlelo zokusebenza zamanje eziphansi (kufika ku-125A), kanti i-MCCB ifaneleka kuzidingo zamanje eziphezulu (100A kuya ku-2500A).

2. Ukulungiswa: Ama-MCB anezilungiselelo zohambo ezihleliwe, kanti ama-MCCB anikeza izilungiselelo zohambo ezilungisekayo, okuvumela ukuguquguquka okukhulu ekuvikeleni isekethe.

3. Ukusetshenziswa: Ama-MCB asetshenziswa kakhulu ezindaweni zokuhlala kanye nezindawo zokuhweba ezilula, kanti ama-MCCB aklanyelwe ukusetshenziswa kwezimboni kanye nezindawo zokuhweba ezisindayo, okubandakanya imithwalo emikhulu kanye nezinhlelo eziyinkimbinkimbi kakhulu.

4. Usayizi Nomklamo: Ama-Miniature circuit breaker (ama-MCB) ngokuvamile mancane futhi mancane kune-molded case circuit breaker (ama-MCCB), okwenza kube lula ukuwafaka ezindaweni ezilinganiselwe. Ama-Molded case circuit breaker (ama-MCCB) makhulu, adinga isikhala esiningi, futhi avame ukufakwa kuma-switchgear assemblies.

5. Izindleko: Ama-Miniature circuit breaker (ama-MCB) ngokuvamile ashibhile kune-molded case circuit breaker (ama-MCCB), okwenza abe yisisombululo esingabizi kakhulu sezinhlelo zokusebenza ezincane. Kodwa-ke, ukusebenza kwawo okwandisiwe kanye nokusebenza kwawo kuwenza abe yitshalomali elifanele ezindaweni ezinkulu nezidinga kakhulu.

Ngokufigqiwe

Ngamafuphi, ama-miniature circuit breaker (ama-MCB) kanye nama-molded case circuit breaker (ama-MCCB) womabili adlala indima ebalulekile ekuvikelweni kwesekethe, kodwa ukusetshenziswa kwawo kanye namakhono awo kuyahlukahluka kakhulu. Ukuqonda lo mehluko kubalulekile ekukhetheni idivayisi efanele izidingo zakho ezithile. Kungakhathaliseki ukuthi uvikela isekethe encane yokuhlala noma uhlelo olukhulu lwezimboni, ukukhetha i-circuit breaker efanele kuqinisekisa ukuphepha, ukuthembeka, kanye nokusebenza kahle kwemishini yakho kagesi. Njalo xhumana nochwepheshe kagesi noma unjiniyela kagesi ofanelekayo ukuze anqume ikhambi elingcono kakhulu lesimo sakho esithile.
