Mayelana nalolu hlelo lokusebenza

KULESI SICWANGCISO SEKUFINELE ISIHLOKO ESISEKELAYO

1. UKUVIKELA
- izikimu zokuvikela
(i) nezinhlelo zokuvikela ezilinganiselayo eziyisisekelo.
(ii) nezinhlelo zokuvikela amanani entengo.
(iii) umshayeli wendiza
(iv) umshayeli-omncane.
- Izinhlobo zezindlela zokudlulisa
(i) i-coil engapheli yamandla kazibuthe.
(i) ugongolo olulinganiselayo
(ii) uhlobo lokungenisa oluphethe edluliselwe
(iv) udlulise ibanga
(v) udluliselwe olungahambisani
(vi) ukubuyiswa kwesimo okuqinile.

-Izimpawu zokuvikela iyunithi

(i) ukuvikelwa kukhiqizi
(ii) ukuvikelwa kwe-transformer

(iv) ukulahleka kwamandla

- Ukusebenza kwesigaba sokuvumelanisa kuguqulwa
(i) ukubolekisa nokuhola
(ii) i-volt eyehlisa isinxephezelo


3. FUTHA IZIMPAWU ZOKUGCINA
- Ukuhlukaniswa kwemigqa yokudlulisela
(i) imigqa emifushane, ephakathi nendawo emide
- Izimbangela zokushiswa komugqa wokudlulisela
(i) ukuqondisa nokukhanyisa okungaqondile ngokuqondile
(ii) imigqa evulekile ejikeleziwe
(iii) imigqa emifushane yokujikeleza
(iv) amaphutha omhlaba wokumelana
--phenomenon idlula incazelo emgqeni wokudlulisela
(i) ukushesha kokuhlinzwa
(ii) ukuthinteka kokuhlinzwa
(iii) uvule imigqa eyisiyingi esetshenzisiwe isiyingiwe
- Ukulondolozwa komugqa wokudluliselwa ngokumelene nama-surges
(i) ngaphezulu kocingo lomhlaba
(ii) izikhala zophondo
(iii) i-silicon ne-zinc oxides diverts yokuhlinza
(iv) Ikhoyili kaPeterson

IMISEBENZI YOKWENZA YAMAHHALA
- Amaphutha womugqa wamandla
(i) isigaba esisodwa sephutha elisisekelo (L - G)
(ii) amaphutha wesigaba 3 (L - L -L)
(iii) umugqa ophindwe kabili wephutha lomhlabathi (L - L - G)
- Ukubhalwa kwezakhi zokulinganisa
(i) i-veterion eqondile, emibi ne-zero yokulandelana
(ii) Umatikuletsheni wokuxhumeka okungcono kwephutha
(iii) umjikelezo olingana wephutha elingenakulinganiswa
- Ukusebenziseka kokufana kokujikeleza okufana nokwesekethe nokulinganisa

5. UKWAKHIWA KWAMANDLA WAMANDLA
-synchronous generator solid
(i) umthethonqubo wokudluliswa kwamandla
(ii) ukukhishwa kwendawo efanayo yenqubomgomo
(iii) Ukushintshwa komthwalo
(iv) ushintsho ekuguqukeni kokudluliswa ngenxa yokushintshwa
(v) ushintsho ekushintsheni kokushintshwa ngenxa yamaphutha

--Ukuqonda kwe-swing equation
- Isithaphu
-Izindlela zokuthuthukisa zombili izinkathi ezilandelanayo nokuqina okuqinile kwesimo
