Marka hore, waxaan u baahannahay inaan xaddidno baaxadda dooda si aan uga fogaanno in ay noqoto mid aan sax ahayn. Koronto-dhaliyaha halkan lagaga hadlay waxa uu tilmaamayaa koronto-dhaliye saddex-waji ah oo AC ah oo aan burush lahayn, oo hadda ka dib loo tixraacayo oo keliya “dhaliye”.
Dab-dhaliye noocaan ah wuxuu ka kooban yahay ugu yaraan saddex qaybood oo waaweyn, kuwaas oo lagu xusi doono doodaha soo socda:
Koronto-dhaliyaha ugu weyn, oo u qaybsan stator-ka weyn iyo rotor-ga weyn; Rotor-ka ugu weyn wuxuu bixiyaa garoon birlab ah, iyo stator-ka ugu weyn wuxuu soo saaraa koronto si uu u bixiyo culeyska; Exciter, oo loo qaybiyay stator exciter iyo rotor; Stator-ka exciter wuxuu bixiyaa goob birlab ah, rotor-ku wuxuu dhaliyaa koronto, ka dib marka la hagaajiyo is-beddelka wareegtada, waxay siisaa koronto rotor-ka ugu weyn; Hagaajinta Voltage Automatic (AVR) waxay ogaataa tamarta wax soo saarka ee koronto-dhaliyaha ugu weyn, waxay koontaroolaysaa hadda ee gariiradda stator exciter, oo waxay gaadhay hadafka xasilinta tamarta wax soo saarka ee stator-ka weyn.
Sharaxaada shaqada xasilinta danabka AVR
Hadafka hawlgelinta ee AVR waa in la joogteeyo korantada wax soo saarka dhalisa ee deggan, oo loo yaqaanno "dejinta korantada".
Hawlgalkeedu waa in la kordhiyo stator hadda ee exciter marka danabka wax soo saarka ee koronto-dhaliyuhu ka hooseeyo qiimaha go'an, taas oo u dhiganta kordhinta hadda excitation ee rotor ugu weyn, taasoo keentay danab koronto ugu weyn in ay kor u qiimaha go'an; Taas lidkeeda, yaree dhaqdhaqaaqa kicinta oo u ogolow danabku inuu yareeyo; Haddii danab-soo-saarka koronto-dhaliye uu la mid yahay qiimaha la dejiyay, AVR-gu waxa uu sii wadaa wax-soo-saarka jira iyada oo aan la hagaajin.
Intaa waxaa dheer, marka loo eego xiriirka wejiga ee u dhexeeya hadda iyo korantada, culeysyada AC waxaa loo kala saari karaa saddex qaybood:
culeyska iska caabinta, halka hadda uu ku jiro marxaladda korantada lagu dabaqay; Xamuulka wax-soo-saarka, marxaladda hadda jirta ayaa ka dambaysa danabka; load Capacitive, marxaladda hadda waa ka hor danab. Isbarbardhigga saddexda sifo ee culeyska waxay naga caawineysaa inaan si wanaagsan u fahamno culeysyada awoodda leh.
Culaysyada iska caabbinta ah, culeyska weyn, ayaa sii weynaanaya dhaqdhaqaaqa kicinta ee loo baahan yahay rotor-ka weyn (si loo dejiyo tamarta wax soo saarka ee koronto-dhaliyaha).
Doodda soo socota, waxaan u isticmaali doonaa dhaqdhaqaaqa kicinta ee looga baahan yahay culeysyada iska caabinta sida halbeeg tixraaceed, taas oo macnaheedu yahay in kuwa waaweyn loo tixraacayo kuwa waaweyn; Waxaan ugu yeernaa in ay ka yar tahay.
Marka culeyska koronto-dhaliye uu firfircoon yahay, rotor-ga ugu weyn wuxuu u baahan doonaa koror xoog leh si uu koronto-dhaliyuhu u ilaaliyo korantada wax-soo-saarka oo deggan.
Culays awood leh
Marka koronto-dhaliye uu la kulmo culeys awood leh, qulqulka kicinta ee loo baahan yahay rotor-ka weyn ayaa yaraa, taas oo macnaheedu yahay in hadda kacsanaanta la dhimo si loo dejiyo tamarta wax soo saarka ee koronto-dhaliyaha.
Maxay tani u dhacday?
Waa in aan weli xasuusannaa in hadda on load capacitive waa ka hor korantada, iyo kuwan qulqulka hogaanka (qulqulaya iyada oo stator ugu weyn) waxay dhalin doontaa hadda keentay on rotor ugu weyn, taas oo dhacda in ay si togan u dulsaaran hadda excitation, kor u magnetic field of rotor ugu weyn. Markaa waxa hadda socda ee soo-saarku waa in la dhimo si loo ilaaliyo tamarta wax-soo-saarka ee deggan.
Inta uu sii weynaado culeyska awoodda leh, ayaa yaraanaya wax soo saarka kicinta; Marka culeyska korantada uu kordho ilaa xad, wax-soo-saarka kicinta waa in la dhimo eber. Wax-soo-saarka kicinta waa eber, taas oo ah xadka koronto-dhaliye; Halkaa marka ay marayso, korantada wax-soo-saarka ee koronto-dhaliye ma noqon doonto mid iskeed u deggan, iyo nooca korontadu maaha mid u qalma. Xaddidaaddan waxa sidoo kale loo yaqaan 'xaddidaadda kicinta'.
Koronto-dhaliye wuxuu aqbali karaa oo keliya awoodda culeyska xaddidan; (Dabcan, koronto-dhaliye la cayimay, waxaa sidoo kale jira xaddidaadyo cabbirka culeyska iska caabinta ama kicinta.)
Haddii mashruuca uu dhibsado culeysyo awood leh, waxaa suurtagal ah in la doorto isticmaalka ilaha tamarta IT-ga oo leh awood yar halkii kiilowatt, ama isticmaal inductor si magdhow ah. Ha u ogolaan qalabka koronto-dhaliye inuu ku shaqeeyo meel u dhow aagga "hoos u xaddidan kicinta".
