Ama-Miniature circuit breaker (ama-MCB) kanye nama-molded case circuit breaker (ama-MCCB) womabili angamadivayisi abalulekile ezinhlelweni zikagesi ezisetshenziselwa ukuvikela ekugcwaleni ngokweqile, ama-short circuit, kanye namanye amaphutha. Nakuba inhloso ifana, kusekhona umehluko phakathi kwalokhu okubili ngokwe-capacitance, izici zokukhubeka, kanye nomthamo wokuphuka.

I-Miniature Circuit Breaker (MCB)

A I-Miniature circuit breaker (MCB)iyithuluzi likagesi elincane elisetshenziselwa ukuvikela amasekethe kumasekethe amafushane kanye nokulayisha ngokweqile. Livame ukusetshenziswa ekufakweni kukagesi ezakhiweni zokuhlala nezebhizinisi futhi lenzelwe ukuvikela amasekethe ngamanye esikhundleni sezinhlelo zikagesi eziphelele.

I-Molded case circuit breaker (MCCB)

A I-Molded Case Circuit Breaker (MCCB)iyi-circuit breaker enkulu neqinile ephinde isetshenziswe ukuvikela ama-circuit kuma-short circuits, overloads, kanye namanye amaphutha. Ama-MCCB aklanyelwe izilinganiso eziphezulu zama-voltage kanye namanje ezisetshenziswa kwezentengiselwano, ezimbonini kanye nasezindaweni zokuhlala ezinkulu.

Umehluko Omkhulu Phakathi kwe-MCCB ne-MCB

Isakhiwo:Ama-MCB amancane kakhulu ngobukhulu kunama-MCCB. I-MCB yakhiwe umucu we-bimetallic ogoba lapho ugesi udlula umkhawulo othile, oqala i-MCB bese uvula umjikelezo. Kodwa isakhiwo se-MCCB siyinkimbinkimbi kakhulu. Indlela kagesi isetshenziswa ukuqala umjikelezo lapho ugesi udlula umkhawulo othile. Ngaphezu kwalokho, i-MCCB inokuvikelwa kwamandla kagesi okushisa ukuvikela ekucindezelweni ngokweqile kanye nezifunda ezimfushane.

Umthamo:Ama-MCB avame ukusetshenziselwa izilinganiso zamandla kagesi kanye nezinga eliphansi le-voltage ezakhiweni zokuhlala nezebhizinisi. Ngokuvamile afinyelela ku-1000V futhi anezilinganiso eziphakathi kuka-0.5A no-125A. Ama-MCCB aklanyelwe izinhlelo zokusebenza zezimboni nezentengiselwano ezinkulu futhi angaphatha ama-current asukela kuma-amps ayi-10 kuya kuma-amps ayi-2,500.

Umthamo Wokuphula:Umthamo wokuphuka yinani eliphezulu lamandla kagesi angalungile angakhubeka i-circuit breaker ngaphandle kokubangela umonakalo. Uma kuqhathaniswa ne-MCB, i-MCCB inamandla aphezulu okuphuka. Ama-MCCB angaphazamisa amandla kagesi afinyelela ku-100 kA, kuyilapho ama-MCB ekwazi ukuphazamisa ama-kA ayi-10 noma ngaphansi. Ngakho-ke, i-MCCB ifaneleka kakhulu kuzinhlelo zokusebenza ezinomthamo omkhulu wokuphuka.

Izici Zokukhubeka:Inzuzo ye-MCCB kanye ne-MCB ukulungiselelwa kohambo okulungisekayo. I-MCCB ivumela ukulungiswa komuntu ngamunye kokulibaziseka kwesikhathi sohambo kanye nesikhathi ukuze kuvikelwe izinhlelo zikagesi kanye nemishini ngendlela ephumelela kakhulu. Ngokuphambene nalokho, ama-MCB anezilungiselelo zohambo ezihleliwe futhi ngokuvamile aklanyelwe ukukhubeka ngenani elithile lamanje.

Izindleko:Ama-MCCB avame ukubiza kakhulu kune-MCB ngenxa yobukhulu bawo, izici zokusebenza, njll. Ama-MCCB ngokuyinhloko anomthamo ophezulu kanye nezilungiselelo zokuhamba ezilungisekayo. Ama-MCB ngokuvamile ayinketho engabizi kakhulu yokuvikela izinhlelo ezincane zikagesi kanye nemishini.

Isiphetho

Ngamafuphi, ama-MCCB nama-MCB adlala indima ebalulekile ekuvikeleni amasekethe kumasekethe amafushane, ukulayisha ngokweqile, kanye nezinye izinkinga ezinhlelweni zikagesi. Nakuba imisebenzi noma izinjongo zalezi zinto ezimbili zifana, kusenomehluko ekusetshenzisweni. Ama-MCCB afaneleka kangcono ezinhlelweni zikagesi ezinkulu ezinezidingo zamandla aphezulu, kuyilapho ama-MCB engabizi kakhulu futhi efanelekile ukuvikela izinhlelo zikagesi ezincane nemishini. Ukwazi lokhu kungafani kuzokusiza ukhethe i-circuit breaker efanele izidingo zakho ezithile futhi uqinisekise ukuthi uhlelo lwakho lukagesi luhlala luphephile futhi lusebenza kahle.
