Uhlelo lokuvusa olungenamabhulashi luyisisombululo esisetshenziswa kabanzi sokuhlinzeka ngogesi wamandla omhlaba kumajeneretha ahambisanayo ezitshalweni zamandla kagesi, iziteshi zamandla okushisa, kanye nezinhlelo zamandla ezimboni. Ngokususa amabhulashi nezindandatho zokushelela, kuthuthukisa kakhulu ukuthembeka, kunciphisa izidingo zokulungisa, futhi kuthuthukisa ukuphepha kokusebenza.
Namuhla, izinhlelo zokuvuselela ezingenamabhulashi zijwayelekile kumayunithi akhiqiza amanzi aphakathi nendawo amakhulu ngenxa yobulula bawo bomshini kanye nokuphila isikhathi eside kwenkonzo.
1. Ukucushwa Okuyisisekelo
Uhlelo olujwayelekile lokuvusa olungenamabhulashi luqukethe:
Isilawuli Se-Voltage Esizenzakalelayo (i-AVR)
I-AC Exciter
Ukuhlanganiswa Kwe-Rectifier Ejikelezayo (i-Diode Bridge)
Injini Eyinhloko Yokugoqa Insimu Ye-Rotor
Zonke izingxenye ezijikelezayo zifakwe kushafu efanayo nejeneretha eyinhloko, zakha isakhiwo esihlanganisiwe.
2. Isimiso Sokusebenza
Uhlelo lokuvusa olungenamabhulashi lusebenza kanje:
2.1 Ukutholwa Kwe-Voltage
I-AVR iqapha njalo i-voltage ye-terminal generator.
2.2 Ukulawulwa Kwensimu Ejabulisayo
Uma i-voltage iphambuka enanini elibekiwe, i-AVR ilungisa ugesi we-DC ohlinzekwa ku-exciter field winding.
2.3 Ukukhiqiza i-AC
I-AC exciter ikhiqiza ugesi oshintshashintshayo wesigaba esithathu ku-armature yayo.
2.4 Ukulungiswa Okujikelezayo
Ukukhishwa kwe-AC kwesigaba ezintathu kulungiswa kube yi-DC ngebhuloho le-diode elijikelezayo elifakwe ku-shaft.
2.5 Ukunikezwa Kwensimu Eyinhloko
Ugesi we-DC olungisiwe ungena ngqo ekujikeni kwe-rotor yejeneretha eyinhloko, okusungula insimu kazibuthe edingekayo ukuze kukhiqizwe ugesi.
Ngenxa yokuthi ukulungiswa kwenzeka emshafini ojikelezayo, asikho isidingo samabhulashi noma amasongo okushelela.
3. Izici Eziyinhloko Zobuchwepheshe
3.1 Isakhiwo Esingenamabhulashi
Ukungabikho kwamabhulashi kuqeda ukuguguleka kokungqubuzana, uthuli lwekhabhoni, kanye nezinkinga ezibangela inhlansi.
3.2 Ukuthembeka Okuphezulu
Njengoba kunezingxenye ezimbalwa zokuthintana ngomshini, uhlelo lufinyelela amazinga aphansi okuhluleka kanye nezikhawu zesevisi ezinde.
3.3 Ukulungiswa Okuphansi
Ukugcinwa njalo kuhilela kakhulu ukuhlolwa kwama-diode ajikelezayo kanye nokuxhumeka kukagesi.
3.4 Ukusebenza Okuhle Okuguquguqukayo
Nakuba kungasheshi njengezinhlelo zokuvuselela ezimile, ukuvuselela okungenamabhulashi kunikeza impendulo eyanele kuzinhlelo eziningi zikagesi wamanzi kanye nezimboni.
4. Izinzuzo Ekusetshenzisweni Kwamandla Kagesi
Ezitshalweni zikagesi zamanzi, ikakhulukazi lezo ezisezindaweni ezinezintaba noma ezikude, ukuvusa ngaphandle kwamabhulashi kunikeza izinzuzo ezibalulekile zokusebenza:
Umthwalo womsebenzi wokulungisa oncishisiwe
Ukusebenza okuzinzile kwesikhathi eside
Ukuphepha kokusebenza okuthuthukisiwe
Ukuzivumelanisa nezimo okuphezulu kokushintshashintsha komthwalo
Eziteshini zamanzi ezihamba emanzini noma eziphakathi nendawo, lapho ukuthembeka nobulula kubalulekile khona, izinhlelo ezingenamabhulashi zivame ukuba yisinqumo esikhethwayo.
5. Imisebenzi Yokuvikela Nokuqapha
Izinhlelo zesimanje zokuvusa ezingenamabhulashi zinezici zokuvikela ezithuthukisiwe, okuhlanganisa:
Umkhawulo wokuvusa ngokweqile
Umkhawulo ongaphansi kokuvusa
Ukuvikelwa kokushisa okuphezulu kwensimu
Ukuvikelwa kokulahlekelwa ukuvusa
Ukutholwa kokwehluleka kwe-diode
Ukuqapha izinga lokushisa le-Rotor
Ama-AVR edijithali athuthukisa ukunemba kokulawula kanye nokuxilonga uhlelo, okuthuthukisa ukuphepha kweyunithi iyonke.
6. Izitayela Zentuthuko
Izinhlelo zesimanje zokuvusa ezingenamabhulashi ziyathuthukela ku:
Ukulawula i-AVR yedijithali ephelele
Ukwakhiwa kokulawula okungafuneki
Ukuqapha ku-inthanethi kanye nokuxilongwa okukude
Ukuhlanganiswa nezinhlelo zokwenza izinto ngokuzenzakalela kwezitshalo
Njengoba izidingo zegridi ziba nzima futhi ukungena okuvuselelekayo kuyanda, ukulawulwa kokuvuselela okuhlakaniphile kudlala indima ebaluleke kakhulu ekuzinzeni kwamandla kagesi kanye nokuphathwa kwamandla okusabela.
Uhlelo lokuvusa olungenamabhulashi lunikeza ikhambi eliqinile nelinobungani nokugcinwa kwemishini yokukhiqiza insimu ehambisanayo. Umklamo walo olula wemishini, ohlanganiswe nobuchwepheshe besimanje bokulawula idijithali, uqinisekisa ukusebenza okuthembekile, okuphephile, nokusebenza kahle.
Ekusetshenzisweni kwamandla kagesi kanye nezimboni, ukuvuselela ngaphandle kwamabhulashi kuhlala kungenye yezixazululo zokuvuselela ezisebenzayo kakhulu futhi ezamukelwa kabanzi emhlabeni jikelele.
