Qonda Umehluko PhakathiI-MCBfuthiI-ELCB
Kulabo abangajwayelene namagama kagesi, amagama athi MCB kanye ne-ELCB azwakala sengathi ayilutho ngaphandle kochungechunge lwezinhlamvu ezingahleliwe. Kodwa-ke, emkhakheni wobunjiniyela kagesi, lezi zifinyezo zibaluleke kakhulu futhi zingadlala indima enkulu ekugcineni ukuphepha kukagesi. Kulesi sihloko sebhulogi, sizobheka kabanzi umehluko phakathi kwama-MCB nama-ELCB, nokuthi avikela kanjani izinhlelo zikagesi kanye nabasebenzisi.
Ake siqale siqonde ukuthi i-MCB kanye ne-ELCB zimeleni. I-MCB imele i-miniature circuit breaker kanye ne-ELCB imele i-earth leakage circuit breaker. Womabili la madivayisi aklanyelwe ukuphula i-circuit uma kwenzeka iphutha, kodwa asebenza ngezindlela ezihlukile kancane futhi anezisetshenziswa ezihlukile.
I-MCB, njengoba igama lisho, iyi-circuit breaker encane eyenzelwe ukuvikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane. Uma ugesi omningi ugeleza kakhulu kusekethe, i-MCB izokhubeka futhi inqamule isekethe ngokuzenzakalelayo ukuvimbela umonakalo emishinini exhunyiwe noma kuzintambo. Lokhu kwenza i-MCB ibe yingxenye ebalulekile ekuvimbeleni imililo kagesi kanye nokuvikela ukuphepha kwabasebenzisi besistimu kagesi.
Ngakolunye uhlangothi, ama-ELCB angama-circuit breaker aklanyelwe ngqo ukuvikela ukuvuza noma amaphutha omhlaba. Athola ukuvuza okuncane kwamandla kagesi okuvela kubaqhubi abaphilayo ku-circuit kuya phansi futhi akhubeke ku-circuit lapho kutholakala ukuvuza okunjalo. Lokhu kubaluleke kakhulu ukuvimbela ukushaqeka kukagesi uma kwenzeka imishini ihluleka noma izintambo zomoya ezilimele.
Omunye wemehluko omkhulu phakathi kwe-MCB ne-ELCB yindlela ezisebenza ngayo. Isimiso sokusebenza se-MCB yisimiso sokukhubeka kwe-thermal magnetic, esizokhubeka lapho ugesi uphezulu kakhulu noma kwenzeka i-short circuit. Ngakolunye uhlangothi, i-ELCB isebenza ngokuthola ukungalingani kwamanje phakathi komqhubi ophilayo kanye nomqhubi ongathathi hlangothi. Lapho kutholakala ugesi ovuzayo, i-ELCB ikhubeka i-circuit ukuze ivimbele izingozi zikagesi.
Ngokuphathelene nokusetshenziswa kwayo, ama-MCB avame ukusetshenziswa ukuvikela izintambo zikagesi kanye nemishini emakhaya, ezakhiweni zebhizinisi, kanye nasezindaweni zezimboni. Ungumugqa wokuqala wokuzivikela ekugcwaleni ngokweqile kanye nama-short circuits, okuqinisekisa ukuphepha kohlelo lukagesi kanye nawo wonke umuntu olusebenzisayo. Ama-ELCB, ngakolunye uhlangothi, avame ukusetshenziswa lapho kunengozi enkulu yokuvuza kukagesi, njengezifudumezi zamanzi, ukufakwa kukagesi kwangaphandle, noma izindawo ezimanzi.
Kwezinye izimo, i-MCB ne-ELCB zingahlanganiswa zibe yidivayisi eyodwa ebizwa ngokuthiI-RCBO(i-residual current breaker kanye nokuvikelwa kokulayisha ngokweqile). Le divayisi ihlanganisa izinzuzo ze-MCB kanye ne-ELCB ukuze ihlinzeke ngokuvikelwa kokulayisha ngokweqile, ukujikeleza okufushane kanye nokuvikelwa kwamaphutha omhlaba. Lokhu kuyenza ibe yisisombululo esiguquguqukayo nesiphelele sokuqinisekisa ukuphepha kukagesi ezinhlotsheni ezahlukahlukene zezicelo.
Kubalulekile ukuqaphela ukuthi nakuba ama-MCB nama-ELCB ebalulekile ekuphepheni kukagesi, awavimbeli. Ukugcinwa nokuhlolwa njalo kubalulekile ekuqinisekiseni ukuthi la madivayisi asebenza kahle. Ngaphezu kwalokho, kubalulekile ukuwafaka uchwepheshe kagesi oqeqeshiwe ukuqinisekisa ukuthi alinganiswe kahle futhi afakwe ngokwezidingo ezithile zesistimu kagesi.
Ngamafuphi, zombili i-MCB kanye ne-ELCB ziyizingxenye ezibalulekile ekugcineni ukuphepha kukagesi kanye nokuvimbela izingozi. I-MCB ivikela ekugcwaleni ngokweqile kanye nama-short circuits, kuyilapho i-ELCB ivikela emaphutheni omhlaba noma ekuvuza kwamanzi. Ukuqonda umehluko phakathi kwalawa madivayisi amabili kanye nemisebenzi yawo kubalulekile ekugcineni uhlelo lukagesi oluphephile noluthembekile. Kungakhathaliseki ukuthi asetshenziswa ngawodwana noma ngokuhlanganiswa, lawa madivayisi adlala indima ebalulekile ekuqinisekiseni ukuphepha kokufakwa kukagesi kanye nabasebenzisi bawo.
