Imisebenzi kanye nomehluko phakathi kwe-MCB ne-RCCB

UkuqondaAma-MCBfuthiAma-RCCBIzingxenye Ezibalulekile Zokuphepha Kukagesi

Ukuphepha kubaluleke kakhulu ekufakweni kukagesi. Ama-Miniature circuit breaker (MCBs) nama-residual current circuit breaker (RCCBs) ayizingxenye ezimbili ezibalulekile zokuqinisekisa ukuphepha kukagesi. Lawa madivayisi amabili anokusetshenziswa okuhlukile kodwa avame ukusetshenziswa ndawonye ukunikeza ukuvikelwa okuphelele emaphutheni kagesi. Lesi sihloko sihlola imisebenzi, umehluko, kanye nokusetshenziswa kwama-miniature circuit breaker (MCBs) nama-residual current current breaker (RCCBs), sigcizelela ukubaluleka kwawo ezinhlelweni zikagesi zesimanje.

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, iphazamise ukuhamba kogesi. Lokhu kuvimbela umonakalo ongaba khona ezintweni zikagesi futhi kunciphisa ingozi yomlilo obangelwa ukuxhuma izintambo ngokweqile.

Ama-Miniature circuit breaker (ama-MCB) alinganiswa ngogesi ngokuya ngomthamo wawo wokuthwala ugesi, ngokuvamile asukela ku-6A kuya ku-63A. Aklanyelwe ukusethwa kabusha ngesandla ngemva kokukhubeka, ayindlela elula yezinhlelo zikagesi zasemakhaya nezebhizinisi. Abalulekile ekuvikeleni izifunda ngazinye, njengokukhanyisa, ukushisa, kanye nezindawo zokufaka ugesi, ukuqinisekisa ukuthi ukwehluleka kwesifunda okukodwa akuthinti lonke uhlelo lukagesi.

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 kwama-conductor aphilayo nangathathi hlangothi, okungase kwenzeke ngenxa yokwehluleka kokufakwa kokushisa noma ukuthintana ngengozi nezingxenye eziphilayo, okubangela ukuthi ugesi uvuza uye phansi. Uma lokhu kungalingani kutholakala, i-RCCB iyaphazamisa futhi inqamule umjikelezo, okunciphisa kakhulu ingozi yokushaqeka kukagesi kanye nomlilo.

Ama-RCCB atholakala ngezilinganiso eziningi zamanje, ngokuvamile kusukela ku-30mA yokuvikela umuntu siqu kuya ku-100mA noma ku-300mA yokuvikela imishini. Ngokungafani nama-MCB, ama-RCCB awahlinzeki ngokuvikela ngokweqile noma nge-short-circuit, ngakho-ke avame ukusetshenziswa kanye nama-MCB ekufakweni kukagesi.

Umehluko obalulekile phakathi kwe-MCB ne-RCCB

Nakuba ama-MCB nama-RCCB womabili ebalulekile ekuphepheni kukagesi, anemisebenzi ehlukene:

1. Uhlobo Lokuvikelwa: I-MCB ivikela ekugcwaleni ngokweqile kanye nokujikeleza okufushane kanti i-RCCB ivikela ekushayweni komhlaba kanye nokushaqeka kukagesi.
2. Indlela Yokusebenza: Ama-Miniature Circuit Breaker (ama-MCB) asebenza ngokusekelwe emazingeni wamanje, akhubeke lapho ugesi udlula umkhawulo obekiwe. Ama-Residual Current Circuit Breaker (ama-RCCB) asebenza ngokusekelwe ekungalinganini kwamanje, akhubeke lapho kunomehluko phakathi kogesi ophilayo nowe-neutral.
3. Setha kabusha: I-MCB ingasethwa kabusha ngesandla ngemva kokukhubeka, kuyilapho i-RCCB ingadinga ukusethwa kabusha ngesandla ngemva kokuxazululwa kwephutha.

Ukusetshenziswa kwe-MCB kanye ne-RCCB

Ezindaweni zokuhlala nezentengiselwano, ama-miniature circuit breaker (ama-MCB) nama-residual current circuit breaker (ama-RCCB) avame ukusetshenziswa ndawonye ukwakha uhlelo lokuvikela ugesi oluqinile. Isibonelo, ekhaya elijwayelekile, ama-MCB angase afakwe ezibanini nasezindaweni zamandla, kuyilapho ama-RCCB angase asetshenziswe ezindaweni ezinobungozi obukhulu njengezindlu zangasese namakhishi, lapho amathuba okuba nogesi aphakeme khona.

Ezisetshenzisweni zezimboni, ama-MCB nama-RCCB abalulekile ekuvikeleni imishini nemishini emaphutheni kagesi, ukuqinisekisa ukusebenza okuphephile nokunciphisa isikhathi sokungasebenzi.

Ekuphetheni

Ngamafuphi, ama-miniature circuit breaker (ama-MCB) kanye nama-residual current circuit breaker (ama-RCCB) ayizingxenye ezibalulekile zezinhlelo zokuphepha kagesi. Ama-MCB avikela ekugcwaleni ngokweqile kanye nama-short circuit, kuyilapho ama-RCCB evikela emaphutheni omhlaba kanye nokushaqeka kukagesi. Ukuqonda imisebenzi kanye nokusetshenziswa kwala madivayisi kubalulekile kunoma ubani ohilelekile ekufakweni noma ekulungisweni kukagesi. Ngokuhlanganisa ama-MCB nama-RCCB, singakha indawo kagesi ephephile, sivikele abantu kanye nempahla ezingozini zamaphutha kagesi.
