11. Emva kokuba umbane osebenzayo ethathe iseti yomvelisi wedizili, ngawaphi amanqaku amathathu ekufuneka aqinisekiswe kuqala?
Impendulo: 1) Qinisekisa amandla aluncedo okwenyani. Emva koko misela amandla oqoqosho kunye namandla agciniweyo. Indlela yokuvuma amandla eluncedo yeyunithi yile: Iiyure ezili-12 ezilinganisiweyo zamandla enjini yedizili iphindaphindwe nge-0.9 ukufumana idatha (kw). Ukuba amandla alinganisiweyo wenkunkuma angaphantsi okanye alingana nale datha, amandla alinganisiweyo wenkunkuma amiselwe njengamandla alulutho okwenyani ukuba umbane wenkunkuma ulinganisile umbane mkhulu kuneli nani
Ngokwedatha, idatha kufuneka isetyenziswe njengamandla aluncedo okwenyani.
2) Qinisekisa ukuba yeyiphi imisebenzi yokuzikhusela iyunithi enayo.
I-3) Jonga ukuba ingaba i-wiring yamandla yeyunithi iyafaneleka na, nokuba ngaba umhlaba okhuselayo uyathembeka, nokuba ngaba umthwalo wesigaba esithathu ulungelelene ngokufanelekileyo.
12. Kukho ilifti eqala ngeemoto ezingama-22KW, yeyiphi isayizi yejeneretha emiselweyo ekufuneka ixhotyiswe ngayo?
Impendulo: 22 * ​​7 = 154KW (ilifti yimodeli eqala ngqo yokulayisha, kwaye ukuqala kwangoko kwesiqhelo kungamaxesha asixhenxe ngoku ukulinganiswa kwangoku ukuqinisekisa ukuba ilifti ihamba ngesantya esingagungqiyo). (Oko kukuthi, ubuncinci iseti yejeneretha eyi-154KW kufuneka ixhotyiswe)
13. Ungawabala njani awona mandla mhle (amandla oqoqosho) eseti yomvelisi?
Impendulo: P ngcono = 3/4 * P ikaliwe (Oko kukuthi, 0.75 amaxesha amandla alinganisiweyo).
14. Ngokwemigaqo kazwelonke, angakanani amandla enjini eseti yomvelisi ngokubanzi kufuneka abe ngaphezu kwejenereta?
Impendulo: 10℅.
15. Amandla enjini ezinye iiseti zomvelisi abonakaliswe kumandla ehashe. Uguqula njani amandla ehashe kwiiyunithi zekilowatts zamanye amazwe?
Impendulo: 1 amandla ehashe = 0.735 kilowatts, 1 kilowatt = 1.36 amandla enjini.
