Uma uhlelo lwehluleka, lungakwazi ukurekhoda ngokuzenzakalelayo nangokunembile izinguquko zamanani ahlukahlukene kagesi ohlelweni ngaphambi nangemva kwephutha. Ngokuhlaziywa nokuqhathaniswa kwalezi zibalo zikagesi, ingozi ingahlaziywa futhi ibhekane nayo. Idlala indima ebalulekile ekwahluleleni ukuthi ukuvikela kusebenza kahle futhi kuthuthukise izinga lokusebenza okuphephile kwesistimu yamandla.
48. Kungani kufanele kufakwe amajoyinti okunweba kumabhasi aqinile?
Impendulo: Izinto zinezici zokwandisa nokunciphisa okushisayo, futhi ubude bebhasi buzoshintsha ngenxa yokushisa ngesikhathi sokusebenza. Ukuze ugweme ukucindezeleka ngokweqile kanye nokulimala kwebhasi kanye ne-insulator esekelayo ngenxa yezinguquko ekwandiseni okushisayo nokunciphisa, amalunga okwandisa kufanele afakwe ku-busbar eqinile.49. Ingakanani idigri yesinxephezelo sekhoyili yokucindezela i-arc futhi iyini imanje eyinsalela?Impendulo: Isilinganiso somehluko phakathi kwe-inductive current kanye ne-capacitive current yekhoyili yokucindezela i-arc kanye ne-capacitive current yegridi yamandla ibizwa ngokuthi idigri yesinxephezelo. Ngemva kokuba i-inductive current yekhoyili yokucindezela i-arc inxephezela i-capacitive current, i-residual current egeleza endaweni okuphansi ibizwa ngokuthi i-residual current.50. Uma isistimu enephoyinti eliphakathi nendawo elisekelwe kukhoyili yokucindezela i-arc isebenza ngokujwayelekile, ingabe ikhoyili yokucindezela i-arc inawo amandla ombane?Impendulo: Uma uhlelo lusebenza ngokujwayelekile, ngenxa yokungalingani komugqa wesigaba sesithathu ukuya phansi, kukhona i-voltage ethile phakathi kwendawo engathathi hlangothi yenethiwekhi nomhlabathi, futhi inani le-voltage lihlobene ngokuqondile ukungalingani kwamandla. Ngaphansi kwezimo ezijwayelekile, i-voltage ekhiqizwa iphuzu elingathathi hlangothi ayikwazi ukudlula u-1.5% wevolthi yesigaba esilinganiselwe.
