Kungani ama-MCB ehamba njalo?Ungakugwema kanjani ukukhubeka kwe-MCB?

Amaphutha kagesi angase acekele phansi izimpilo eziningi ngenxa yokugcwala kakhulu noma amasekhethi amafushane, futhi ukuze kuvikelwe ekulayishweni okuningi nokujikeleza okufushane, kusetshenziswa i-MCB.I-Miniature Circuit Breakers(ama-MCB) angamadivayisi e-electromechanical asetshenziselwa ukuvikela isekethe kagesi kokuthi Ukulayishwa Okukhulu & Okufushane Circuit.Izizathu eziyinhloko ze-overcurrent zingase zibe isifunda esifushane, ukulayisha ngokweqile noma ngisho nomklamo ongalungile.Futhi lapha kule bhulogi, sizokutshela isizathu sokukhubeka kwe-MCB njalo nezindlela zokuyigwema.Lapha, bheka!

Izinzuzo ze-MCB:

● Isekhethi kagesi iyazicisha uma kuphakama isimo esingavamile senethiwekhi

● Indawo enephutha yesekhethi kagesi ingabonakala kalula, njengoba iknob yokusebenza isuka endaweni lapho ikhubeka.

● Ukubuyisela ngokushesha ukunikezwa kungenzeka esimweni se-MCB

● I-MCB iphephe kakhudlwana ngogesi kune-fuse

Izici:

● Izilinganiso zamanje azikho ngaphezu kuka-100A

● Izici zohambo ngokuvamile azilungiseki

● Ukusebenza okushisayo nozibuthe

Izici nezinzuzo ze-MCB

1. Ukuvikela ekushaqekeni nasemliloni:

Okokuqala kanye nesici esibaluleke kakhulu se-MCB ukuthi isiza ekuqedeni ukuthintana ngephutha.Isetshenziswa futhi ilawulwa ngaphandle kwenkinga.

2. Oxhumana nabo be-Anti welding:

Ngenxa yempahla yayo elwa nokushisela, iqinisekisa impilo ephakeme nokuphepha okwengeziwe.

3. Itheminali yokuphepha noma izikulufu ezithunjiwe:

Idizayini yetheminali yohlobo lwebhokisi inikeza ukunqanyulwa okufanele futhi igweme ukuxhumana okuxekethile.

Izizathu zokuthi kungani ama-MCB ehamba njalo

Kunezizathu ezi-3 zokukhubeka kwe-MCB njalo:

1. Isekhethi egcwele ngokweqile

Ukulayishwa ngokweqile kwesekethe kwaziwa njengesizathu esivame kakhulu sokukhubeka kwe-circuit breaker.Kusho nje ukuthi sisebenzisa amadivayisi amaningi kakhulu asebenzisa amandla asindayo ngesikhathi esisodwa kumjikelezo ofanayo.

2. Isifunda esifushane

Isizathu esilandelayo esiyingozi kakhulu isifunda esifushane.Isekethe emfishane yenzeka lapho ucingo/isigaba sithinta enye intambo/isigaba noma ithinta intambo “emaphakathi” kwisekhethi.I-current ephezulu igeleza lapho lezi zintambo ezimbili zithinta ukudala ukugeleza kwamanje okusindayo, okungaphezu kwalokho okungaphathwa yisekethe.

3. Iphutha eliphansi

Iphutha eliphansi licishe lifane nesekhethi emfushane.Lesi simo senzeka lapho intambo eshisayo ithinta intambo yaphansi.

Empeleni, singasho ukuthi ngesikhathi lapho isekethe inqamuka, kusho ukuthi i-current idlula ama-AMPs uhlelo lwakho olungakwazi ukuwaphatha, okungukuthi isistimu igcwele kakhulu.

Iziphuli ziyithuluzi lokuphepha.Yakhelwe ukuvikela izinto zokusebenza kuphela kodwa izintambo kanye nendlu.Ngakho-ke, lapho i-MCB ihamba, kunesizathu futhi le nkomba kufanele ithathwe ngokungathi sína kakhulu.Futhi uma usetha kabusha i-MCB, futhi iphinde ihambe ngokushesha, khona-ke ngokuvamile ibonisa ukufushane okuqondile.

Esinye isizathu esivamile sokuthi i-breaker ihambe ukuxhumeka kukagesi okuxekethile futhi kungalungiswa kalula ngokuwaqinisa.

Amanye amathiphu abalulekile okugwema ukukhubeka kwe-MCB

● Kufanele sikhiphe wonke amadivaysi lapho ingasebenzi

● Kufanele siqaphele ukuthi zingaki izinto zikagesi ezixhunywayo lapho kushisa noma kubanda

● Kufanele uqiniseke ukuthi ayikho intambo yakho kagesi eyonakele noma ephukile

● Gwema ukusebenzisa ikhebula elinwetshiwe kanye nemigqa yamandla uma unezindawo ezimbalwa zokuphuma

Imijikelezo emifushane

Uhambo lwe-circuit breaker luvela lapho uhlelo lwakho lukagesi noma olunye lwezinhlelo ozisebenzisayo lunemfushane.Kwamanye amakhaya, kunzima ukubona ukuthi ikuphi okufushane.Futhi ukuthola kafushane ocingweni, sebenzisa inqubo yokususa.Vula amandla bese uxhuma umshini ngamunye ngamunye ngamunye.Bona ukuthi ingabe into ethile esebenza kagesi ibangela uhambo lwama-breaker.

Ngakho-ke, yingakho i-MCB ihamba njalo nezindlela zokugwema ukukhubeka kwe-MCB.
