Yini iukuhlukanisa ukushintsha?Uyini umsebenzi weswishi yokuhlukanisa?kanjani ukukhetha?Okuthiwaukuhlukanisa ukushintshaumshini wommese omkhulu, okuwuhlobo olufakwa emnyango.Ingakwazi ukunqamula amandla ngempumelelo.Ngaphansi kwe-voltage ephezulu, iswishi ehlukanisayo akufanele ibe neswishi yokulayisha.Amaswishi anomthwalo azokhipha ugesi wodwa, ukusha okuncane nokufa okubi kakhulu.Ama-Disconnectors asetshenziswa ngokuhambisana nama-circuit breakers ngaphansi kwe-voltage ephezulu.Lapho ulungisa umzila, vula futhi unqamule amandla ukuze uqinisekise ukuphepha kwabasebenzi bokulungisa.Esiteshini esincane esingu-11kv, iswishi yokuhlukanisa kagesi ihlukaniswe yaba iswishi eyodwa yaphansi, iswishi yokubeka phansi kabili kanye neswishi yokubopha ibhasi.Iswishi yokubeka phansi emaphakathi Ekuhlolweni kwe-voltage ephezulu, lokho okubizwa nge-single grounding switch kusho ukuthi uma ukhanyisa futhi uvala, uhlangothi olulodwa lomzila lubekwe phansi ukuze kuqinisekiswe ukuphepha.Okufanayo kuya ku-double ground switch.Iswishi yebha yebhasi iswishi enqamula ibha yebhasi.Lapho ibhasi liphelelwa amandla, iswishi yokumisa emaphakathi ingadlulisela amandla.Iqhaza elibalulekile lokuzihlukanisa limi kanje.1. Enqubweni yokugcinwa kwemishini kagesi ephezulu naphansi, isishintshi sokuhlukanisa sisetshenziselwa ukuhlukanisa amandla kagesi kanye nengxenye yokuphakela amandla, kwakha indawo esobala yokunqamula, ukuze okokusebenza kokulungisa kuhlukaniswe nokokufaka kwamandla kagesi. uhlelo lokuqinisekisa ukuphepha kwabasebenzi besondlo kanye nemishini kagesi.2. Ukuze ushintshe imodi yokusebenza, ukushintshwa kokuhlukanisa kanye ne-circuit breaker kuyasebenzisana ukuze kwenziwe umsebenzi wokushintsha.①Uma i-module breaker ephumayo inamabhasi amabili anezintambo ezidlulayo ngenxa yezinye izizathu, vala ilokhi bese usebenzisa i-bypass circuit breaker nokunye ukusebenza, iswishi yokuhlukanisa ingasetshenziswa ukuxhuma isekethe;②Ngokwezintambo ezivalwe kancane, lapho uchungechunge lwama-breaker wesifunda luvulwa futhi luvalwa, inkinobho yokunqamula ingasetshenziswa ukukhulula isifunda (kodwa sicela uqaphele ukuthi wonke amanye ama-circuit breaker kufanele abe sendaweni evaliwe);③ Kumodi yokufaka izintambo ye-busbar yesigaba esisodwa, lapho i-breaker yesifunda yama-breaker ebhasi amabili kanye ne-section breaker ivuliwe noma ivaliwe, isekethe inganqanyulwa ngokushintsha okuhlukanisayo.Ukuhlukaniswa kwamaswishi ahlukanisa ugesi Amaswishi ahlukanisa ugesi angahlukaniswa abe amaswishi ahlukanisayo kagesi njengokuzungezisa ovundlile, ukuzungezisa okuqondile, i-plug-in namanye amaswishi ahlukanisa kagesi.Iswishi yokuhlukanisa kagesi ingahlukaniswa ibe yikholomu eyodwa, ikholomu ekabili kanye neswishi yokuhlukanisa kagesi enekholomu emithathu.Eqinisweni, i-switchgear engaxhuma noma inqamule amandla.Eminye imininingwane emincane nje yeswishi yokuhlukanisa kagesi.Isibonelo, uma iswishi yokuhlukanisa kagesi isendaweni engaphansi, kuba nesikhala esicacile sokuxhumana phakathi koxhumana nabo, futhi kukhona nophawu olucacile lokuhlukanisa.Uma iswishi yokuhlukanisa kagesi isendaweni evaliwe, iswishi yokuhlukanisa kagesi ingamelana namaza ngaphansi kwesekhethi evamile kanye namazinga angavamile, njengamasekhethi amafushane ngaphansi kwezindinganiso ezingavamile.Iswishi ehlukanisayo inqamula ukunikezwa kwamandla kanye nemodi yokudlulisa amandla, inqamule i-breaker yesifunda, ivumela isifunda ukuthi inqamule umthwalo, inqamule iswishi yokuhlukanisa lapho kungekho mthwalo, futhi ihlola ukuthi i-breaker circuit inqanyuliwe yini.Vala iswishi yokunqamula, bese uvala i-circuit breaker
