Uyini umsebenzi we-circuit breaker, isimiso sokusebenza se-circuit breaker yincazelo enemininingwane
Uma uhlelo luhluleka, isenzo sokuvikela sesici esinephutha kanye nokwehluleka kokusebenza kwe-circuit breaker yenqaba ukuhamba, hamba i-circuit breaker eseduze yesiteshi esincane ngokuvikela isici esinephutha, futhi isiteshi singasetshenziswa ukwenza izintambo ze uhambo lwe-distal circuit breaker ngesikhathi esifanayo lubizwa ngokuthi ukuvikela ukwehluleka kwe-circuit breaker.
Ngokuvamile, ngemva kwesenzo sezingxenye zamanje zesigaba, amaqembu amabili okuqala amaphoyinti okuxhumana ayaphuma, futhi izindawo zokuxhumana zokuvikela isenzo sangaphandle zixhunywe ochungechungeni lwesekethe, isixhumanisi sebhasi noma ukwehluleka kwesegimenti ye-segment breaker ukuqalisa ukuvikela ukwehluleka.
Iyini imisebenzi yama-circuit breaker
Ama-Circuit breaker asetshenziswa kakhulu kumamotho ajwayelekile kanye nama-transformer umthamo omkhulu kanye neziteshi ezingaphansi.I-Circuit breaker inomsebenzi wokuhlukanisa umthwalo wengozi, futhi isebenzisana nokuvikela okuhlukahlukene kokudlulisela ukuvikela izinto zikagesi noma izintambo.
I-Circuit breaker ngokuvamile isetshenziswa ekukhanyeni kwe-voltage ephansi, ingxenye yamandla, ingadlala indima yokusika ngokuzenzakalelayo isifunda;i-circuit breaker kanye nokulayisha ngokweqile kanye nokuvikelwa kwesifunda esifushane kanye neminye imisebenzi eminingi, kodwa inkinga yomthwalo ophansi idinga ukulungiswa iswishi yokunqamula idlala indima yokuhlukanisa kagesi, futhi ibanga le-creepage le-circuit breaker alanele.
Manje sekukhona i-circuit breaker enomsebenzi wokuzihlukanisa, okuyi-breaker circuit evamile kanye nomsebenzi wokuxhuma kabili kokukodwa.I-circuit breaker enomsebenzi wokuhlukanisa ingase ibe isinqamuli somzimba.Eqinisweni, ukushintshwa kwesixhumi ngokuvamile akusebenzi ngomthwalo, kuyilapho i-breaker circuit inomjikelezo omfushane, ukuvikela ukulayisha ngokweqile, ukucindezela ngaphansi kwengcindezi kanye neminye imisebenzi yokuvikela.
Isimiso sokusebenza se-circuit breaker sinemininingwane
Uhlobo oluyisisekelo: Idivayisi elula yokuvikela isekethe i-fuse.I-fuse iyintambo encane kakhulu, enekesi elivikelayo bese ixhunywe kumjikelezo.Ngemuva kokuthi isifunda sivaliwe, yonke imisinga kufanele igeleze ku-current ku-fuse -- fuse njenge-current efanayo kwamanye amaphuzu kumjikelezo ofanayo.I-fuse iklanywe ngendlela yokuthi ikwazi ukuhlangana lapho izinga lokushisa lifinyelela izinga elithile.Ukubhoboza i-fuse kungabangela imigwaqo evulekile ukuze kuvinjwe amandla amaningi ekulimazeni izintambo zendlu.Inkinga ngefuse ukuthi ingasebenza kanye kuphela.Noma nini lapho i-fuse ishiswa, kufanele ishintshwe.Ama-circuit breaker angenza indima efanayo nama-fuse, kodwa angasetshenziswa ngokuphindaphindiwe.Ngokushesha lapho i-current ifinyelela ezingeni eliyingozi, ibangela ngokushesha isifunda esivulekile.
Isimiso esiyisisekelo sokusebenza: intambo yomlilo kumjikelezo ixhunywe kuzo zombili iziphetho zokushintshwa.Lapho iswishi ibekwe endaweni, i-current igeleza iphuma kutheminali engezansi, ilandelana ngomzimba ka-electromagnetic, othintana nabo beselula, abathintwayo abanganyakazi, futhi ekugcineni isuke kutheminali ephezulu.I-current ingakwazi ukudonsa uzibuthe we-electromagnetic.Amandla kazibuthe akhiqizwa uzibuthe we-electromagnetic ayanda namanje, futhi uma okwamanje kuncipha.Lapho okwamanje kugxumela ezingeni eliyingozi, umuzwa we-EM ukhiqiza amandla kazibuthe amakhulu ngokwanele ukudonsa induku yensimbi exhunywe ekuxhumekeni kweswishi.Lokhu kubangela ukuthi i-contactor ehambayo inyakaze futhi ishiye i-contactor emile, bese inqamula isifunda.Umsinga kagesi nawo uphazamisekile.Ibha ye-bimetal iklanyelwe ngokusekelwe esimisweni esifanayo, umehluko wukuthi asikho isidingo sokunikeza amandla omzimba we-electromagnetic lapha, kodwa ivumela ibha yensimbi ukuthi igobe ngesikhathi esiphezulu, bese uqala idivayisi yokuxhumanisa.Amanye ama-circuit breaker nawo agcwalisa iziqhumane ukuhambisa iswishi.Lapho i-current idlula izinga elithile, ithungela into eqhumayo bese ishayela ipiston ukuvula iswishi.
Amamodeli athuthukisiwe: Ama-circuit breaker athuthuke kakhulu ashiya izinto zikagesi ezilula futhi esikhundleni salokho asebenzise amadivaysi kagesi (ama-semiconductor) ukuze aqaphe amazinga amanje.I-Ground fault circuit breaker (GFCI) wuhlobo olusha lwe-circuit breaker.Lesi siphuzo sesifunda asikwazi nje ukuvimbela ukulimala kwe-wiring yendlu, kodwa futhi sivikele abantu ekushayweni kukagesi.
Umsebenzi othuthukisiwe: I-GFCI ihlale iqapha okwamanje kuqanda kanye nemigqa yomlilo kusekethe.Uma yonke into ijwayelekile, okwamanje kuyo yomibili imigqa kufanele ifane ncamashi.Uma ulayini womlilo ususekelwe ngokuqondile (ngokwesibonelo, othile uthinte ulayini womlilo ngephutha), i-current on the fire line ngokuzumayo iyanda, kuyilapho ulayini we-zero ungashintshi.I-GFCI inqamula isekethe ngokushesha ngemva kokuthola lesi simo ukuze ivimbele ukulimala ngenxa yokushaqeka kukagesi.Ngenxa yokuthi i-GFCI ingathatha isinyathelo ngaphandle kokulinda kuze kube yilapho okwamanje kukhuphukela ezingeni eliyingozi, isabela ngokushesha kakhulu kunezinqamuli zesekethe ezivamile.
