Ii-circuit breaker evuzayo(idivayisi yokuvikela ukuvuza) iyidivayisi yokuvikela kagesi enganqamula ukunikezwa kukagesi ngesikhathi lapho imishini kagesi yehluleka futhi ivimbele ukwenzeka kokushaqeka kukagesi komuntu siqu.i-residual current breakerikakhulukazi yakhiwe ngokuhleleka kwangaphakathi kanye nesakhiwo sangaphandle.
Indlela yangaphakathi yakhiwe yiyunithi yokulawula kagesi, idivayisi yokumisa engathathi hlangothi, ukugoqa kwesibili, ukuthintana okuhambayo kanye nokuxhumana okungaguquki, njll.
Isakhiwo sangaphandle sakhiwe ngegobolondo, iyunithi yokulawula kagesi, idivayisi yokudlulisa kagesi kanye nedivayisi yokumisa, futhi inezici zomthamo omncane, isisindo esincane kanye nokufakwa okulula. Uma ihlanganiswe nesivikelo sokuvuza, ayikwazi nje kuphela ukufeza umsebenzi wokuvikela wesivikelo esiphelele emgqeni, kodwa futhi ikwazi ukufeza umsebenzi wokuvikela wesiluphu sesigaba esisodwa kanye nemishini yesigaba esisodwa, futhi ingasetshenziswa ukuvikela umthwalo wesigaba esisodwa ku-loop ngayinye yegatsha.Idivayisi yokuvikela ukuvuzaiyithuluzi lokuvikela kagesi eliphelele elinesistimu yokuxhumana njengesikhungo, ukuxhumanisa ukuxhumana kanye nesikhathi sokusebenza njengemingcele. Lingavikela ukuphepha komuntu siqu, livikele imishini kagesi, livikele uhlelo lwamandla kanye nempahla yesizwe ekulahlekelweni, futhi linganqamula ngokushesha ukunikezwa kwamandla uma kwenzeka ingozi.
Kunezinhlobo ezintathu zezivikelo zokuvuza: Izivikelo zokuvuza ze-Class I ziyakwazi ukusika ugesi we-pole omuhle nongemuhle one-voltage engu-zero ukuya phansi; Izivikelo zokuvuza ze-Class II ziyakwazi ukusika ucingo lomlilo, ucingo olu-zero, ucingo lomhlabathi kanye nokunye ukunikezwa kwamandla kwe-loop okungahleliwe; Izivikelo zokuvuza ze-Class III ziyakwazi ukusika ugesi ngomsebenzi wokuvikela i-short circuit. Uhlobo ngalunye lwesivikelo sokuvuza lunemisebenzi yalo: I-Class I (evame ukusetshenziswa kakhulu) isetshenziselwa kakhulu ukuxhumana ngqo nomonakalo wokushaqeka kagesi; I-Class II (evame ukusetshenziswa kakhulu) isetshenziselwa kakhulu ukuxhumana okungaqondile nomonakalo wokushaqeka kagesi; kanye ne-Class III (evame ukusetshenziswa kakhulu) isetshenziselwa kakhulu ukuvimbela izinhlansi nama-arcs okubangelwa umonakalo wokushisa wemishini nemigqa.
Isiciama-tics
1, Ukuvikelwa kokulayisha ngokweqile kanye nokuvikelwa kwesekethe emfushane kungenziwa ngaphakathi kobubanzi obuthile, futhi ugesi ungalawulwa ngenkinobho ephaneli ngaphakathi kobubanzi obuthile.
2. Ineziphetho ezintathu, ezixhunywe ngokulandelana nomugqa wesigaba samanje oshintshanayo ongu-220V kanye nomugqa womhlaba wokuvikela (umugqa we-N), ngakho-ke isivikelo sokuvuza singavikela imigqa emithathu ngasikhathi sinye.
3. Isikhathi sokusebenza kufanele sinqunywe ngokwesikhathi esichazwe emithethweni, futhi akufanele siphambuke esikhathini sokusebenza ngenxa yokuguquguquka kwamandla kagesi noma ukukhululeka kwesixhumi somqhubi, futhi kufanele sibe yisivikelo sangempela sokuvuza "esingasebenzi ngokweqile".
4. Uma kukhona i-short circuit emugqeni, umugqa ngokwawo ngeke usebenze; uzokhubeka kuphela uma kukhona i-fault current emugqeni, futhi uma kune-short circuits ezingaphezu kwezimbili emugqeni, uzokhubeka.
5, Ingasetshenziswa ngokuzimela njengedivayisi yokuvikela ukuphepha noma kanye nezinye izifunda zokuvikela.
