Yiziphi izinkinga zama-air circuit breakers (ACB)?

1. I-air circuit breaker yakhubeka futhi yehluleka ukuvala kabusha:
Okokuqala, thola ukuthi i-air circuit breaker ikhubeke yini ngaphandle kwengozi. Ukukhubeka okungeyona ingozi kusho ukuthi ikhubeke ngaphandle kwephutha le-short circuit noma i-overload. Kunezizathu eziningi zokuthi kunganii-air circuit breakerayikwazi ukuvala. Okokuqala, kubalulekile ukunquma ukuthi ukuhamba kubangelwa yi-short circuit kanye nokugcwala ngokweqile, noma ukuthi i-circuit breaker uqobo noma i-control circuit inephutha. Landela lezi zinyathelo ezingezansi ukuze uthole imbangela yephutha. Okokuqala, bheka ukuthi i-primary circuit inezintambo ezimnyama noma ezishile kanye noxhumana nabo, nuka ukuthi kukhona yini iphunga elingavamile, nokuthi ngabe kukhona yini iphutha ku-secondary control circuit efanele ku-low-voltage cabinet. Uma kutholakala indawo yephutha, ingasebenza ngokujwayelekile ngemva kokususwa; uma kungekho ndawo yephutha esobala etholakala, i-circuit breaker ivaliwe ngaphansi kwezimo zokungalayishi. Uma i-circuit breaker ikhubeka futhi isengasakwazi ukusebenza, i-air circuit breaker ngokwayo inephutha; Uma i-circuit breaker ivaliwe, akukho phutha ku-circuit breaker uqobo. Khona-ke amaphutha omugqa wegatsha atholakala ngokulandelana.
2. Ukwehluleka kwesilawuli esihlakaniphile se-air circuit breaker:
Ngemva kokuba isilawuli esihlakaniphile se-air circuit breaker sihlulekile, kuzovela into yokuvala ngesandla, ukuvala ngogesi, kanye nokwehluleka komsebenzi wokuvikela wezigaba ezintathu kanye neminye imisebenzi yokuvikela. Ukwehluleka kwesilawuli esihlakaniphile ngokuvamile kubangelwa ukushisa ngenxa ye-voltage eningi. Ngokuvamile, abakhiqizi balandela amazinga kazwelonke afanele futhi baklama i-voltage yokusebenza elinganisiwe ibe yi-400V. Kodwa-ke, ekusebenzeni kwangempela, lapho ukusetshenziswa kwamandla kwehla phakathi kobusuku, uma i-transformer ingalawulwa yi-voltage, i-voltage ivame ukufika ku-420V nangaphezulu. Umthamo omkhulu wenza i-smart. Isilawuli sishiswe ngenxa ye-voltage ephezulu. Enye inkinga evamile yesilawuli ukuthi uma imemori yephutha ingasulwanga ngesikhathi, noma ngabe iphutha legridi yamandla selisusiwe, i-circuit breaker isazocabanga ukuthi igridi yamandla inephutha futhi i-manual noma i-electric circuit breaker ngeke ikwazi ukuvala i-circuit breaker. Ngalesi sikhathi, ungasebenza ngokujwayelekile kuphela ngokulandela imisebenzi ebhukwini lemiyalelo, usule imemori yephutha bese uyisetha kabusha. Abantu abavamile ngeke bacabange ukuthi kungenxa yokuthi isango alikwazi ukuvala, futhi ngokuvamile abakwazi ukuthola imbangela yephutha, noma bayazi imbangela, kodwa ngenxa yokuthi umsebenzi wokuhlanza uyinkimbinkimbi kakhulu, bangathola ochwepheshe abangochwepheshe kuphela, okubangela ukucima kukagesi okungadingekile. Isixazululo ukuthi abakhiqizi be-air circuit breaker kufanele bathuthukise abalawuli abanokumelana okungcono kwengcindezi okulula futhi okunembile ukuyisebenzisa, futhi ngesikhathi esifanayo baqinise ukuqeqeshwa kobuchwepheshe kwabasebenzi.
