Iukuvuza kwe-circuit breaker(idivayisi yokuvikela ukuvuza) iyithuluzi lokuvikela likagesi elinganqamula ukunikezwa kwamandla ngesikhathi lapho okokusebenza kukagesi kungasebenzi futhi kuvimbele ukwenzeka kokushaqeka kukagesi komuntu siqu.Ii-residual current circuit breakerikakhulukazi yakhiwe inhlangano yangaphakathi kanye nesakhiwo sangaphandle.
Umshini wangaphakathi wenziwa iyunithi yokulawula ye-elekthronikhi, idivayisi esekelayo engathathi hlangothi, ukujikajika kwesibili, ukuthintana okunyakazayo kanye nokuxhumana okumile, njll.
Isakhiwo sangaphandle sakhiwe ngegobolondo, iyunithi yokulawula i-elekthronikhi, idivayisi yokudlulisa ugesi kanye nedivayisi yokumisa phansi, futhi inezici zevolumu encane, isisindo esincane nokufaka kalula.Ihlanganiswe nesivikeli sokuvuza, ayikwazi nje ukubona umsebenzi wokuvikela womvikeli ophelele kulayini, kodwa futhi ibone umsebenzi wokuvikela we-single-phase loop kanye nemishini yesigaba esisodwa, futhi ingasetshenziswa ukuvikela umthwalo wesigaba esisodwa iluphu yegatsha ngalinye.Idivayisi yokuvikela ukuvuzaiyithuluzi elibanzi lokuvikela ugesi elinesistimu yokuxhumana njengesikhungo, ukuxhumana kokuxhumana nesikhathi sokusebenza njengamapharamitha.Ingavikela ukuphepha komuntu siqu, ivikele izinto zikagesi, ivikele isistimu yamandla kanye nempahla kazwelonke ekulahlekeni, futhi inganqamula ngokushesha ukunikezwa kwamandla uma kwenzeka ingozi.
Kunezinhlobo ezintathu zezivikeli zokuvuza: Izivikeli zokuvuza ze-Class I ziyakwazi ukunqamula ukunikezwa kwamandla esigxobo esihle nesibi nge-voltage enguziro ukuya phansi;Izivikeli zokuvuza ze-Class II ziyakwazi ukunqamula izintambo zomlilo, izintambo eziziro, izintambo eziphansi kanye nokunye ukuhlinzekwa kwamandla kagesi we-loop;Izivikeli zokuvuza ze-Class III ziyakwazi ukunqamula ukunikezwa kwamandla ngomsebenzi wokuvikela isekethe emfushane.Uhlobo ngalunye lwesivikeli sokuvuza lunemisebenzi yalo: I-Class I (evame ukusetshenziswa kakhulu) isetshenziselwa ikakhulukazi ukuthintana okuqondile nomonakalo wokushaqeka kagesi;I-Class II (evame ukusetshenziswa kakhulu) isetshenziselwa ikakhulukazi ukuthintana okungaqondile nomonakalo wokushaqeka kagesi;kanye ne-Class III (evame ukusetshenziswa kakhulu) ngokuyinhloko isetshenziselwa ukuvimbela izinhlansi nama-arcs okubangelwa ukulimala kokufakwa kwezinto zokusebenza nemigqa.
Isimilotics
1, Ukuvikelwa kokulayishwa ngokweqile kanye nokuvikelwa kwesekethe emfushane kungenziwa phakathi kwebanga elithile, futhi okwamanje kungalawulwa ngeknobhu kuphaneli ngaphakathi kwebanga elithile.
2, Inamatheminali amathathu, axhunywe ngokulandelana kwesigaba sesigaba samanje esingu-220V kanye nomugqa ophansi wokuvikela (umugqa ongu-N), ngakho umvikeli wokuvuza angakwazi ukuvikela imigqa emithathu kanyekanye.
3, Isikhathi sokusebenza sizonqunywa ngokwesikhathi esishiwo kwimithethonqubo, futhi ngeke sichezukiswe esikhathini sokusebenza ngenxa yokuguquguquka kwamandla kagesi noma ukuxegiswa kwesixhumi sikakhondatha, futhi kuyoba ukuvuza kwangempela “okwamanje okungasasebenzi”. umvikeli.
4, Uma kukhona isifunda esifushane emgqeni, umugqa ngokwawo akufanele usebenze;izokhubeka kuphela uma kukhona iphutha emugqeni, futhi uma kunamasekethe amafushane angaphezu kwamabili kulayini, izokhubeka.
5, Ingasetshenziswa ngokuzimela njengedivayisi yokuvikela ukuphepha noma kanye nezinye izifunda zokuvikela.
