Uyini umehluko phakathi kwama-breaker circuit amancane nama-case breaker breaker abunjiwe

I-miniature circuit breaker(ngemuva kwalokhu okubizwa ngokuthi i-MCB) ingumkhiqizo wokushintsha i-circuit breaker onohlu olukhulu lokusetshenziswa nenombolo enkulu.Umsebenzi wayo oyinhloko ukugcina imishini yokusabalalisa amandla emishini yokugcina ubunjiniyela kagesi.Njengoba womabili engezamaswishi ahlukanisayo, ama-circuit breaker epulasitiki afaneleka kakhulu amabhuzu amancane, ngakho-ke kuyasebenziseka kakhulu futhi kubalulekile ukuqonda umehluko phakathi kwakho kokubili bese ukhetha impahla efanele.Iqhaza elibalulekilei-plastic case circuit breaker(ngemuva kwalokhu okubizwa ngokuthi i-MCCB) ukugcina amaphutha omthwalo kanye nesekhethi efushane kumasistimu okusabalalisa amandla kagesi aphansi kanye namasekhethi okulawula ukuvikelwa kwezimoto.Sekuyimpahla ejwayeleke kakhulu embonini ngenxa yokuphepha nokwethembeka kwayo.Nansi incazelo emfushane.
Okokuqala, ake sikhulume ngezinto eziyisisekelo ezivamile.Njengoba womabili ehlukanisa amaswishi, ezinye izindinganiso ezinkulu zokusetshenziswa komkhiqizo zidinga ukulandelwa, futhi imigomo iyafana.Bese ukhuluma ngomehluko phakathi kwakho kokubili.Ngokuvamile, kukhona izici ezilandelayo:
1. Imingcele eyinhloko yemishini kagesi ihlukile.
2. Imingcele eyinhloko yemishini yemishini ihlukile.
3. Ukusetshenziswa kwendawo yehhovisi kuhlukile.
Futhi, ngokombono wokuthenga, empeleni kukhona umehluko omkhulu phakathi kwalokhu kokubili.
Izinga lamanje
Izinga eliphezulu lamanje le-i-plastic case circuit breakerngo 2000A.Izinga eliphezulu lamanje le-i-miniature circuit breakeringaphakathi kwe-125A.Ngenxa yomehluko kumthamo, emsebenzini wangempela, indawo esebenzayo ye-plastic case circuit breaker nayo idlula leyo ye-miniature circuit breaker.Ngesikhathi esifanayo, izintambo ezixhunyiwe nazo zikhulu kakhulu, ezingafinyelela ngaphezu kwamamitha-skwele angu-35, kuyilapho i-circuit breaker encane ifaneleka kuphela ukuxhuma imigqa yokudlulisela ngaphakathi kwamamitha-skwele ayi-10.Ngakho-ke, ngokuvamile, amakamelo amakhulu afaneleka kakhulu ekukhetheni ama-breaker circuit circuit, kuye ngokuthi isimo sekamelo.
Indlela yokufaka
Ama-circuit breaker epulasitiki ahlanganiswe ikakhulukazi nezikulufu, okulula kakhulu ukubambeka, abe nokuxhumana okuhle futhi asebenze kahle.Ama-circuit breaker amancane agxunyekwa kakhulu kumareyili, kwesinye isikhathi okuholela ekuxhumaneni okungekuhle ngenxa yetorque enganele.Ngenxa yezindlela ezihlukene zokufaka, ukuhlangana kwama-circuit breakers epulasitiki kunamandla futhi akunzima kakhulu kunama-circuit breaker amancane.
Ukusebenza kwangempela nempilo yesevisi.
ekusebenzeni kwangempela.Ama-circuit breaker abunjiwe avikelwe amasethi amabili wamadivayisi we-overcurrent kanye ne-short circuit ngokulandelana.Inani lesenzo lokuvikela okudlulele lingalungiswa mathupha, okuyinto elula futhi esheshayo.Ukugeleza okuphambene nephutha le-short-circuit ye-micro-circuit breaker kusebenzisa isethi efanayo yemishini, futhi yamanje ayikwazi ukulungiswa, okuvame ukuba nzima ukuyixazulula.I-mold case circuit breaker inebanga elikhulu le-interphase kanye nesembozo sokucisha i-arc, esinekhono eliqinile lokucisha i-arc, singakwazi ukumelana nomthamo wesekethe emfushane, akulula ukubangela i-interphase short circuit, futhi inempilo ende yesevisi kune-micro circuit breaker.
Sebenzisa amakhono okuxhumanisa.
Ngakolunye uhlangothi, ama-circuit breaker epulasitiki agqame kakhulu, futhi ikhono lawo lokuhlanganisa isethingi linamandla kunalawo ama-circuit breaker amancane.Imishini yokuvikela i-overvoltage kanye ne-overcurrent ye-plastic case circuit breaker ihlukaniswe ukusuka kwenye, futhi inani lesenzo sokuvikela okudlulele lingashintshwa kalula.Ukuvikelwa kwesifunda esifushane kanye nokuvikela okwedlulele kwe-micro-circuit breaker amathuluzi ahlanganisiwe, futhi amandla okulungisa kanye nokuxhumanisa akwanele.
Ngokusekelwe kulokhu okungenhla, kubonakala sengathi wonke ama-MCB asesimweni esingesihle, kodwa empeleni, kwezinye izimo, ama-MCB kufanele akhethwe.Isibonelo, lapho isici sokuphepha somzila kufanele sithuthukiswe, ngenxa yokuzwela kokuma okuphezulu kwe-breaker circuit encane, isenzo sokuphuka siyashesha, esivumelana kakhulu nokugcinwa komzila nezinto zikagesi zasendlini.
Ngakho-ke, singabona ukuthi kokubili kunezinzuzo ezahlukene kanye nezindawo zokusebenza.Kubalulekile ukuqonda ngokugcwele umehluko phakathi kwe-plastic case circuit breakers kanye nama-circuit breaker amancane bese ukhetha ngokuvumelana nezidingo zakho.
