Umehluko phakathi kwe-circuit breaker yecala elibunjiwe kanye ne-miniature circuit breaker

I-circuit breaker yekesi elibunjiwe(I-MCCB) ihlinzeka ngokuvikeleka kokugcwala ngokweqile kanye nesekethe emfishane kusistimu yokusabalalisa amandla kagesi aphansi kanye neluphu yokuvikela imoto.Ngenxa yokuthembeka nokuzinza kwayo, iye yasetshenziswa kakhulu embonini.I-miniature circuit breaker(I-MCB) ibuye isetshenziswe ebangeni elibanzi kanye nenani elikhulu lemikhiqizo ye-circuit breaker, umsebenzi oyinhloko ukuhlinzeka ngokuvikelwa ekwakheni idivayisi yokusabalalisa amandla kagesi wesiphetho.Ngoba bobabili bangabe-breaker circuit, futhiI-MCCBisetshenziswa kakhulu kumthamo omncane wokuvula nokuvala, ngakho qonda umehluko phakathi kwakho kokubili, khetha umkhiqizo olungile ungokoqobo kakhulu futhi ubalulekile.Nansi incazelo esheshayo.

Ake siqale ngokufana okuyisisekelo, ngoba bobabili bangama-circuit breaker, bobabili kufanele balandele izindinganiso zomkhiqizo eziyisisekelo, futhi basebenza ngendlela efanayo.Ake sikhulume ngomehluko phakathi kwabo.Ngokuvamile, kunamaphuzu alandelayo:

1. Amapharamitha ahlukene kagesi
2. Amapharamitha emishini ahlukene
3. Izindawo zokusebenza ezahlukene

Ngaphezu kwalokho okubekwe ku-Engeli yokukhetha nokuthenga, isho okumbalwa kokubili kokuhlukanisa ngokuqondile.

Isilinganiso samanje

Ama-circuit breakers abunjiwebabe nebanga lamanje kuze kufike ku-2000A.Ibanga eliphezulu lamanje le-breaker circuit elincane lingaphakathi kwe-125A.Ngenxa yegebe phakathi kwalokhu okubili komthamo, emsebenzini othize, indawo esebenzayo ye-circuit breaker yecala elibunjiwe inkulu kune-i-miniature circuit breaker, futhi ucingo lokufinyelela luwugqinsi, lungafinyelela ngaphezu kwamamitha-skwele angama-35, futhii-miniature circuit breakerifaneleka kuphela kumamitha-skwele ayi-10 alandelayo ocingo.Ngakho-ke, isimo sangaphakathi esijwayelekile, igumbi elikhudlwana lifaneleka kakhulu ekukhethweni kwe-breaker circuit breaker.

Ukufakwa

I-circuit breaker yekesi elibunjiwengokuyinhloko ifakwe isikulufu, kulula ukuyicindezela, ukuthintana okuhle, ukusebenza okuzinzile.Futhi i-micro circuit breaker ifakwe ikakhulukazi ngomzila wesitimela, ngezinye izikhathi ngenxa ye-torque enganele futhi ibangele ukuthintana kabi.Ngenxa yezindlela zabo zokufaka ezihlukene, ama-circuit breaker abunjiwe azinzile futhi anzima kakhulu ukuwafakaama-breaker circuit amancane.

Ukusebenza nokuphila

Ngokusebenza.I-circuit breaker yekesi elibunjiweithatha amasethi amabili wamadivayisi ukuvikela i-overcurrent kanye ne-short circuit ngokulandelanayo, futhi inani lesenzo sokuvikela okudlulele lingalungiswa mathupha, kube lula futhi kusheshe.Ama-circuit breaker amancane ahlanganyela isethi yamadivayisi we-overcurrent kanye ne-short circuit, futhi yamanje ayikwazi ukulungiswa, okuholela ezimweni eziningi ezingakwazi ukuxazulula inkinga.Ibanga lesigaba sesigaba se-plastic case breaker, kanye nesembozo se-arc, ikhono lokucisha i-arc liqinile, lingakwazi ukumelana namandla amanje we-short-circuit, futhi akulula ukubangela ukujikeleza okufushane kwesigaba, ukuze impilo yesevisi iphinde ibe ngaphezu kwe-breaker circuit encane.

Ukuvumelana nezimo ukusetshenziswa

Kulokhu,ama-breaker circuit abunjiwezigqame kakhulu, futhi ukuguquguquka kwazo ekusetheni kungcono kuneziqephu zesekethe ezincane.Imishini yokuvikela i-overcurrent kanye ne-short circuit yeI-MCCBzizimele, futhi inani lesenzo lokuvikela okudlulele lingalungiswa ngendlela evumelana nezimo.Ukuvikelwa okungaphezulu kwamanje kanye nokuvikelwa kwesekethe emfushane ye-I-MCBzingamadivayisi ahlanganisiwe, futhi kukhona ukushiyeka okuthile ekuguquguqukeni kokulawula.Ngokusho kwesimo esingenhla kubonakala sengathi i-MCB emoyeni, kodwa empeleni isikhathi esithile, noma kudingeka ukhetheI-MCB.

Isibonelo, isidingo sokuthuthukisa ukuphepha komugqa, ngenxa yokuthi isenzo se-MCB sensitiy siphezulu, isenzo sokuphulwa siyashesha, sivumela kakhulu ukuvikela ulayini nezinto zikagesi.Kungabonakala ukuthi bobabili banezinzuzo zabo futhi bafanele ukusetshenziswa, ukhiye uwukuqonda ngokugcwele umehluko phakathii-case circuit breaker elibunjiwekanye ne-miniature circuit breaker, futhi ngokwezidingo zabo zokukhetha.
