I-circuit breakerngokuvamile yakhiwa isistimu yokuxhumana, isistimu yokucisha i-arc, indlela yokusebenza, iyunithi yohambo, kanye nekesi.
Umsebenzi we-circuit breaker ukusika nokuxhuma isifunda somthwalo, futhi unqamule isifunda esinephutha, ukuze uvimbele ukwanda kwengozi nokuqinisekisa ukusebenza okuphephile.I-high-voltage circuit breaker idinga ukuphula i-1500V, futhi yamanje iyi-arc engu-1500-2000A, futhi lawa ma-arcs angakwazi ukwelulelwa ku-2m futhi aqhubeke evutha ngaphandle kokucisha.Ngakho-ke, ukucisha i-arc kuyinkinga okufanele ixazululwe kuma-breaker voltage circuit breaker.
Ama-circuit breaker ane-voltage ephansi, eyaziwa nangokuthi okuzenzakalelayoamaswishi emoyeni, ingasetshenziselwa ukuvula nokuvala amasekhethi okulayisha, futhi ingasetshenziswa ukulawula amamotho aqala njalo.Umsebenzi wayo ulingana nesamba seminye noma yonke imisebenzi yeswishi yommese, ukudlulisa okungaphezu kwamanje, ukudluliswa kokulahlekelwa kwamandla kagesi, ukudluliswa kwe-thermal nesivikelo sokuvuza.Kuyidivayisi ebalulekile yokuvikela kunethiwekhi yokusabalalisa i-low-voltage.
Ama-circuit breaker ane-voltage ephansi anemisebenzi eminingi yokuvikela (ukulayisha ngokweqile,isifunda esifushane, ukuvikelwa kwe-undervoltage, njll.), inani lokusebenza elingaguquguqukayo, umthamo wokuphuka okuphezulu, ukusebenza okulula, ukuphepha, njll., ngakho-ke zisetshenziswa kabanzi.Isakhiwo kanye nesimiso sokusebenza I-Low-voltage circuit breaker yakhiwa indlela yokusebenza, abathintwayo, amadivaysi okuvikela (ukukhishwa okuhlukahlukene), uhlelo lokucisha i-arc nokunye.
Ukuthintana okuyinhloko kwe-low-voltage circuit breaker ivaliwe ngesandla noma ngogesi.Ngemuva kokuthi oxhumene naye oyinhloko evaliwe, indlela yamahhala yokukhubeka ikhiya othintana naye oyinhloko endaweni evaliwe.Ikhoyili yokukhishwa kwe-overcurrent kanye ne-thermal yokukhululwa kwe-thermal kuxhunywe kuchungechunge ngeisifunda esikhulu,futhi ikhoyili yokukhishwa kwe-undervoltage ixhunywe ngokuhambisana nokunikezwa kwamandla.Uma isekethe ine-circuited emfushane noma igcwele kakhulu, i-armature yokukhululwa kwamanje izodonsa ukuze yenze indlela yamahhala yokugibela isebenze, futhi othintana naye oyinhloko uzonqamula isekethe enkulu.Uma isekethe ilayishwe kakhulu, i-elementi eshisayo yokukhululwa kwe-thermal izokhiqiza ukushisa ukuze igobe ishidi le-bimetal, iphushe indlela yokukhishwa yamahhala ukuze isebenze.Uma isifunda singaphansi kwamandla, i-armature yokukhululwa kwe-undervoltage iyakhululwa.Iphinde ivule indlela yamahhala yokuhamba.Ukukhishwa kwe-shunt kusetshenziselwa isilawuli kude.Ngesikhathi sokusebenza okuvamile, ikhoyili yayo iyacishwa.Uma kudingeka ibanga lokulawula, cindezela inkinobho yokuqala ukuze ikhoyili isebenze.
