Imisebenzi kanye nomehluko phakathi kwe-MCB ne-RCCB

UkuqondaAma-MCBfuthiAma-RCCBIzingxenye Ezibalulekile Zokuphepha Kukagesi

Ukuphepha kubaluleke kakhulu emhlabeni wokufakwa kukagesi. Ama-Miniature circuit breaker (ama-MCB) nama-residual current circuit breaker (ama-RCCB) ayizingxenye ezimbili ezibalulekile zokuqinisekisa ukuphepha kukagesi. Lawa madivayisi amabili anokusetshenziswa okuhlukile kodwa avame ukusetshenziswa ndawonye ukuhlinzeka ngokuvikelwa okuphelele emaphutheni kagesi. Lesi sihloko sibheka ngokujulile imisebenzi, umehluko, kanye nokusetshenziswa kwama-miniature circuit breaker (ama-MCB) nama-residual current current breaker (ama-RCCB), futhi siqokomisa ukubaluleka kwawo ezinhlelweni zikagesi zanamuhla.

Kuyini i-MCB?

I-miniature circuit breaker (MCB) iyiswishi ezenzakalelayo esetshenziselwa ukuvikela amasekethe kagesi ekugcwaleni ngokweqile kanye namasekethe amafushane. Lapho ugesi ogeleza ngesekethe udlula umkhawulo onqunyiwe, i-MCB iyakhubeka futhi inqamule ukunikezwa kwamandla. Lokhu kuvimbela ukushisa ngokweqile kanye nezingozi zomlilo ezingaba khona ezibangelwa ugesi odlulele. Ugesi olinganiselwe we-MCB uncike kumthamo wayo wokuthwala ugesi, ngokuvamile phakathi kuka-6A no-63A, futhi wenzelwe ukusebenza ngokushesha ukunciphisa umonakalo kumishini kanye nezintambo.

Ama-Miniature circuit breaker (ama-MCB)zibalulekile ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni. Zivame ukusetshenziswa kuma-switchboard ukuvikela amasekethe ngamanye, ukuqinisekisa ukuthi ukwehluleka kwesekethe okukodwa akuthinti lonke uhlelo lukagesi. Ama-Miniature circuit breaker angasethwa kabusha, ngakho-ke ugesi ungabuyiselwa kalula ngemva kokulungiswa kwephutha, okwenza kube ukukhetha okulula kokuvikela ugesi.

Kuyini i-RCCB?

I-residual current breaker (RCCB), eyaziwa nangokuthi idivayisi ye-residual current (RCD), yenzelwe ukuvikela amaphutha omhlaba kanye nokushaqeka kukagesi. Ithola ukungalingani phakathi kwezintambo ezibukhoma nezingathathi hlangothi, okungenzeka lapho ukufakelwa komoya kwehluleka noma lapho ukuxhumana ngengozi nezingxenye eziphilayo kubangela ukuthi ugesi uvuza phansi. Uma lokhu kungalingani kutholakala, i-RCCB iyaphazamisa futhi inqamule umjikelezo, okunciphisa kakhulu ingozi yokushaqeka kukagesi kanye nomlilo.

Ama-RCCB atholakala ngamazinga ahlukahlukene okuzwela, ngokuvamile asukela ku-30mA yokuvikela umuntu siqu kuya ku-100mA noma ku-300mA yokuvikela imishini. Ukukhetha ukuzwela kuncike esimweni sokusetshenziswa kanye nezinga lokuvikela elidingekayo. Isibonelo, endaweni yokuhlala, i-30mA RCCB ivame ukusetshenziselwa ukuvikela abantu ekushayweni ugesi, kuyilapho ezisetshenziswa ezimbonini, i-RCCB enesilinganiso samandla esiphezulu ingasetshenziswa ukuvikela imishini.

I-MCB vs RCCB: Umehluko Omkhulu

Nakuba ama-miniature circuit breaker (ama-MCB) kanye nama-residual current circuit breaker (ama-RCCB) ebalulekile ekuphepheni kukagesi, enza imisebenzi ehlukene. Umehluko omkhulu usezindleleni zawo zokuvikela:

- I-MCB: Ivikela ekucindezelweni ngokweqile kanye nokujikeleza okufushane. Ayinikezi isivikelo sephutha lomhlabathi noma sokushaqeka kukagesi.
- I-RCCB: Ivikela ekulimaleni komhlaba kanye nokushaqeka kukagesi. Ayinikezi ukuvikelwa kokudlula ngokweqile noma kwe-short circuit.

Ngenxa yalokhu kungafani, ama-miniature circuit breaker (ama-MCB) nama-residual current circuit breaker (ama-RCCB) avame ukusetshenziswa ndawonye ekufakweni kukagesi. Le nhlanganisela inikeza isivikelo esiphelele, iqinisekisa ukuphepha kwezinhlelo zikagesi kanye nabasebenzisi.

Ukusetshenziswa kwe-MCB kanye ne-RCCB

Ezindaweni zokuhlala, ama-miniature circuit breaker (ama-MCB) avame ukusetshenziselwa ukuvikela izibani kanye nezisekelo zamandla, kuyilapho ama-residual current circuit breaker (ama-RCCB) efakwa ezindaweni ezinengozi ephezulu yokushaqeka kukagesi ukuze kuthuthukiswe ukuphepha, njengezindlu zangasese namakhishi. Ezindaweni zezentengiselwano nezezimboni, womabili la madivayisi abalulekile ekuvikeleni imishini nokuqinisekisa ukuphepha kwabasebenzi.

Ngamafuphi, ama-miniature circuit breaker (ama-MCB) nama-residual current circuit breaker (ama-RCCB) ayingxenye ebalulekile yesistimu yokuphepha kagesi. Ukuqonda imisebenzi yawo kanye nezicelo zawo kubalulekile kunoma ubani ohilelekile ekufakweni noma ekugcinweni kukagesi. Ngokuhlanganisa ama-miniature circuit breaker (ama-MCB) nama-residual current current breaker (ama-RCCB), inethi yokuphepha eqinile ingakhiwa ukuze ivikeleke ezingozini ezahlukene zikagesi, iqinisekise indawo ephephile yawo wonke umuntu.
