Naka ngokulinganayo ukuvikelwa nokuthembeka: Ukuchazwa kwezici eziyinhloko zama-molded case circuit breakers

I-Molded Case Circuit Breaker (MCCB)kuyingxenye ebalulekile yesistimu yokusatshalaliswa kwamandla. Yenzelwe ukuvikela ukufakwa kukagesi kanye nabasebenzi ezingozini ezingaba khona ezibangelwa amasekethe amafushane, ukulayisha ngokweqile kanye nezinye izinkinga zikagesi. Ngenxa yokuthembeka nokusebenza kwayo,I-MCCBivame ukusetshenziswa ezakhiweni zezentengiselwano, zezimboni, kanye nezindawo zokuhlala.

Enye yezinzuzo eziyinhloko ze-I-MCCBikhono layo lokuphazamisa ukuhamba kukagesi ngesikhathi sezimo zamaphutha. Uma kwenzeka i-short circuit noma i-overload,I-MCCBisheshe ibone ukugeleza kwamandla kagesi okungajwayelekile futhi ivule ukuxhumana kwayo, ihlukanise ngempumelelo isekethe enephutha kokunye ukufakwa. Lokhu kusabela okusheshayo kusiza ukuvimbela ukushisa ngokweqile kanye nemililo engaba khona, igcine isakhiwo kanye nabantu abahlala kuso bephephile.

Ama-MCCBzaziwa nangokwakhiwa kwazo okuqinile, okuzenza zikwazi ukumelana nemisinga ephezulu. Lawa ma-circuit breaker ngokuvamile enziwe ngezinto ezihlala isikhathi eside, njengezindlu ezibunjiwe, futhi aklanyelwe ukusingatha imithwalo kagesi ehlukahlukene. Angakwazi ukumelana nemisinga ephezulu ye-short-circuit futhi ahlinzeke ngesivikelo esithembekile ngisho nasezindaweni zikagesi ezinzima.

Ngaphezu kwalokho,I-MCCBinikeza izici ezengeziwe zokuthuthukisa ukusebenza kwayo kanye nokuguquguquka. EziningiAma-MCCBfaka izilungiselelo zokuhamba ezilungisekayo, okuvumela umsebenzisi ukuthi enze ngezifiso impendulo ye-circuit breaker emithwalweni ethile kagesi. Lesi sici siwusizo kakhulu ezinhlelweni zokusebenza ezidinga amazinga ahlukene wamanje, njengasezindaweni zezimboni ezinemishini ehlukene.

Ngaphezu kwalokho,Ama-MCCBivame ukuba nezindlela zokuvikela ezakhelwe ngaphakathi ezifana nokukhubeka kokushisa kanye nokwe-magnetic. I-thermal tripper ivikela ekucindezelekeni ngokweqile ngokubona ukushisa ngokweqile, kuyilapho i-magnetic tripper isabela kumjikelezo omfushane ngokubona ukwanda okungazelelwe kwamandla kagesi. Lezi zingqimba eziningi zokuvikela ziqinisekisa ukuthi i-MCCB isabela ngokushesha emaphutheni ahlukahlukene kagesi, inciphisa umonakalo kanye nesikhathi sokungasebenzi.

Ngokufigqiwe,ama-circuit breakers e-case abunjiweziyizingxenye ezibalulekile ezinhlelweni zokusatshalaliswa kwamandla. Ikhono layo lokubona nokusabela ezimweni zamanje ezingavamile, kuhlanganiswe nokwakhiwa kwayo okuhlala isikhathi eside kanye nezici ezengeziwe, kuyenza ithuluzi elibalulekile lokuqinisekisa ukuphepha kukagesi ezinhlotsheni ezahlukene zokusebenza. Kungakhathaliseki ukuthi kusezakhiweni zezentengiselwano, zezimboni noma zokuhlala,Ama-MCCBukuhlinzeka ngokuvikelwa kwamaphutha kagesi okuthembekile nokusebenzayo ukuvikela imishini nabasebenzi.
