Uma isofthiwe yesistimu ihluleka, izingxenye ezivamile zephutha zivikela ukuma, futhi i-circuit breaker empeleni isebenzisa iphutha elivamile ukwenqaba uhambo, i-circuit breaker eseduze yesiteshi esincane izovikela uhambo ngokuvumelana nezingxenye zephutha elivamile.Uma izimo zingavumeli, isiteshi sokuphepha singasetshenziswa ukwenza uhambo lwe-circuit breaker ekude ngesikhathi esifanayo.Indlela yokufaka izintambo ibizwa ngokuthi i-circuit breaker common fault protection.
Ngokuvamile, ngemva kokunyakaza kwezingxenye zamanje zesigaba, amaqembu angu-2 wezixhumi ezisebenzayo atholakala futhi axhunywe ochungechungeni ngezixhumi zokuvikela ukuma kwangaphandle, bese ukuvikela okujwayelekile kwephutha kuqhutshwa endleleni.
Wenzani i-circuit breaker?
Ama-Circuit breaker asetshenziswa kakhulu kumamotho, ama-transformer esikhala amakhulu kanye neziteshi zokusabalalisa ezivame ukunqamula imithwalo.I-circuit breaker inomsebenzi wokuphula umthwalo wengozi yokuphepha, futhi isebenzisana nokuvikela okuhlukahlukene kokudlulisela ukuvikela izinto zikagesi noma imizila.
I-circuit breaker ngokuvamile isetshenziselwa ingxenye yamandla okushayela amalambu aphansi, futhi inganqamula isekethe ngokuzenzakalelayo;i-circuit breaker nayo inemisebenzi eminingana efana nomthwalo nokuvikelwa kwephutha lesifunda esifushane, kodwa uma kunenkinga ngomthwalo ongezansi, kufanele kugcinwe.umsebenzi, futhi i-voltage yokuwohloka ye-circuit breaker ayanele.
Namuhla kukhona i-circuit breaker esebenzayo enokuvikelwa, ehlanganisa imisebenzi ye-breaker circuit jikelele kanye ne-high-voltage disconnector.I-circuit breaker esebenzayo enokuvikela ingasetshenziswa futhi njengeswishi yokuhlukanisa i-voltage ephezulu yomzimba womuntu.Eqinisweni, amaswishi ahlukanisayo anamandla kagesi aphezulu ngokuvamile awakwazi ukusetshenziswa ngomthwalo, kodwa ama-circuit breaker anemisebenzi yokuvikela efana nephutha lesekhethi emfishane, ukuvikela umthwalo, nokuvikela i-voltage engaphansi.
Ichaza isimiso sokusebenza sama-circuit breaker ngokuningiliziwe
Uhlobo Oluyisisekelo: Idivayisi elula yokuvikela isekethe iyi-fuse.I-fuse iyikhebula elincanyana nje, elineshevu elivikelayo, elibe selixhunywa kumjikelezo.Ngemuva kokuthi umjikelezo uvaliwe, wonke ama-current kufanele adlule ku-fuse, futhi i-current ye-fuse ifana ne-current yamanye amaphuzu kumjikelezo ofanayo.Lolu hlobo lwe-fuse luklanyelwe ukuthi luhlale luvulekile lapho izinga lokushisa le-ambient lifinyelela izinga elithile.Ama-fuse awonakele angaholela emigwaqweni eholayo ukuze kuvinjwe amandla amaningi ekulimazeni izintambo zendlu.Inkinga ngefuse ukuthi inomphumela owodwa kuphela.Njalo uma i-fuse ilimele, kufanele ishintshwe kufakwe entsha.I-circuit breaker ingenza umsebenzi ofanayo njenge-fuse, kodwa ingasetshenziswa kabusha izikhathi eziningi.Uma nje i-current ifinyelela ezingeni eliyingozi, izohola ngokushesha indlela.
Isimiso esiyisisekelo: Intambo ephilayo kanye nentambo engathathi hlangothi kusekethe kuxhunywe kuzo zombili izinhlangothi zesishintshi samandla.Uma inkinobho isesimweni esixhunyiwe, intambo yamanje iyakhishwa emshinini ophansi, igeleze ngokulandelana kukazibuthe kagesi, isixhumi esithinta i-AC esinyakazayo, isixhumi se-AC sedatha emile, bese ekugcineni siyakhishwa esisetshenziswa esiphethe esiphezulu.Amandla kagesi angaba nguzibuthe ozibuthe.Amandla kazibuthe akhiqizwa yi-electromagnetic ayanda namanje.Uma i-current iyancipha, amandla kazibuthe nawo azoba buthaka.Lapho i-current igxumela kumthamo oyingozi, umuzwa wokungeniswa kagesi udala amandla kazibuthe aqine ngokwanele ukuhambisa induku yensimbi exhunywe ekuxhumekeni kweswishi yamandla.Lokhu kuzobangela ukuthi i-AC contactor yeselula ijike futhi ishiye isixhumi se-AC yedatha emile, ivule isekethe.Umsinga nawo uphazamisekile.Imichilo yensimbi engagqoki iklanywe ngokwesimiso esifanayo.Ngokungafani nesiNgisi, ayidingi ukunikeza amandla kazibuthe we-kinetic, kodwa kunalokho ivumela umugqa wensimbi ukuthi ugobe ngaphansi kwamandla aphezulu, abese egijima ukuxhumana.Amanye ama-circuit breaker ahambisa iswishi yamandla ngokuya ngokushajwa kweziqhumane.Uma i-current idlula izinga elithile, izothungela izinto ezingavuthiwe ezivuthayo neziqhumayo, bese iphusha induku ye-piston ukuze ucindezele iswishi.
Okuthuthukisiwe: Ama-circuit breaker athuthuke kakhulu akhetha ukushiya izinto zikagesi ezilula futhi asebenzise ugesi (imboni ye-semiconductor) ukuze athole amazinga amanje.I-Ground Fault Interrupter (GFCI) Lolu uhlobo olusha lwe-circuit breaker.Lawa ma-breaker circuit awavimbeli nje ukulimala kwe-wiring yendlu, kodwa futhi avikele abantu kusuka ku-electrocution.
Umgomo othuthukisiwe: I-GFCI izoqhubeka nokuthola amandla amanje ezintanjeni ezimaphakathi nezibukhoma kusekethe.Uma konke kuhamba kahle, imisinga kumasekhethi amabili kufanele ifane ncamashi.Uma ukungathathi hlangothi okubukhoma sekugxiliswe ngokushesha (ngokwesibonelo, abanye abantu bathinte ngephutha ukungathathi hlangothi okubukhoma), umsinga wokungathathi hlangothi okubukhoma uzokhuphuka kungazelelwe, kodwa okumaphakathi ngeke.Lapho i-GFCI ithola into enjalo, inqamula ngokushesha isekethe ukuvimbela ugesi.Ama-GFCI akudingeki alinde kuze kube yilapho izinga lamanje likhuphukela kumazinga ayingozi, ngakho-ke izinga lawo lokuphendula lishesha kakhulu kunama-circuit breaker avamile.
