Ili mkati mwa malo opangira magetsi opangidwa ndi madzi, pakati pa mphamvu yaikulu ya kinetic ya ma turbine ndi malo akuluakulu a gridi yotumizira magetsi, imagwiritsa ntchito ukadaulo wofunikira kwambiri: chosinthira magetsi. Nthawi zambiri sichimaganiziridwa, mlonda wosalankhula uyu ndiye cholumikizira chofunikira kwambiri chomwe chimapangitsa kuti kutumiza mphamvu zamagetsi zongowonjezwdwanso kuchitike mtunda wautali.
Kuchokera pa Madzi Kupita pa Waya: Kufunika Kosintha
Njira yofunikira kwambiri yogwiritsira ntchito mphamvu yamagetsi yamadzi ndi yokongola kwambiri chifukwa ndi yosavuta. Mphamvu zomwe zingagwiritsidwe ntchito kuchokera m'madzi osungidwa zimasanduka mphamvu yamakina ndi turbine, yomwe kenako imazungulira jenereta kuti ipange magetsi. Komabe, magetsi a alternating current (AC) opangidwa ndi makinawa nthawi zambiri amatuluka pamlingo wapakati wa voltage, monga 11 kV, 13.8 kV, kapena 24 kV. Ngakhale kuti ndi oyenera mtunda waufupi, kutumiza mphamvu zambiri pa voltage iyi sikugwira ntchito bwino nthawi yayitali.
Apa ndi pomwe transformer imagwira ntchito yake yofunika kwambiri. Ndi chipangizo chamagetsi chosasinthasintha chomwe chimagwiritsa ntchito mfundo ya induction ya electromagnetic kuti chiwonjezere, kapena "kukweza," voltage yotumizira. Mwa kukweza voltage kufika pamlingo wapamwamba kwambiri—nthawi zambiri 138 kV, 230 kV, 500 kV, kapena kupitirira apo—transformer imachepetsa kwambiri mphamvu yamagetsi yamagetsi pamlingo winawake wamagetsi.
Kuphatikiza kwa mphamvu yamagetsi yamphamvu komanso yotsika kumeneku ndiye chinsinsi cha kutumiza mphamvu moyenera. Malinga ndi lamulo la Joule, kutayika kwa mphamvu mu kondakitala kumafanana ndi sikweya ya mphamvu yamagetsi (P_loss = I²R). Chifukwa chake, pochepetsa mphamvu yamagetsi, transformer imachepetsa kutayika kosasunthika m'mizere yotumizira magetsi, ndikuwonetsetsa kuti mphamvu yoyera yopangidwa ndi mathithi imayenda makilomita mazana ambiri ndi mphamvu yayikulu.
Kapangidwe ka Chosinthira Chomera cha Magazi
Ma transformer m'mafakitale opangira magetsi si mayunitsi wamba; ndi makina olimba, amphamvu kwambiri omwe amapangidwira kuti azidalirika.
Pakati ndi Ma windings: Pakati pake (kwenikweni), imakhala ndi pakati pa chitsulo chopangidwa ndi laminated ndi magulu awiri a ma windings amkuwa kapena aluminiyamu: yoyamba (mbali yamagetsi otsika yolumikizidwa ku jenereta) ndi yachiwiri (mbali yamagetsi apamwamba yolumikizidwa ku gridi).
Njira Yoziziritsira: Kugwiritsa ntchito mphamvu zambiri kumabweretsa kutentha kwakukulu. Ma transformer a zomera zamagetsi amagwiritsa ntchito njira zamakono zoziziritsira, nthawi zambiri amagwiritsa ntchito mafuta osati pongoteteza kutentha kokha komanso pochotsa kutentha. Njira zodziwika bwino zimaphatikizapo:
ONAN (Mafuta Achilengedwe Mpweya Wachilengedwe): Amadalira kufalikira kwa mafuta ndi mpweya mwachilengedwe.
ONAF (Mafuta Achilengedwe Oyendetsedwa ndi Mpweya): Amagwiritsa ntchito mafani kukakamiza mpweya pamwamba pa ma radiator ozizira.
OFAF (Oil Forced Air Forced): Imagwiritsa ntchito mapampu kufalitsa mafuta ndi mafani kuti aziziritse, zomwe zimagwiritsidwa ntchito pa mphamvu yapamwamba kwambiri.
Tanki Yosungira: Gawo lofunika kwambiri ndi thanki yosungira, yomwe imalola kuti mafuta otetezera kutentha azikula ndi kufupika pamene transformer ikutentha ndikuzizira ikugwira ntchito.
Machitidwe Oteteza: Ma transformer awa ali ndi zida zodzitetezera, kuphatikizapo Buchholz relay zomwe zimazindikira zolakwika zamkati, zida zochepetsera kupanikizika, ndi machitidwe apamwamba owunikira kutentha, kusanthula mpweya, ndi kutulutsa pang'ono.
Mavuto Apadera ndi Zoganizira Zokhudza Kapangidwe
Malo omwe chomera chamagetsi chimayendera madzi amakhala ndi zovuta zina pakupanga ndi kuyika transformer.
Malo: Zitha kupezeka m'nyumba, panja, kapena ngakhale m'mapanga apansi panthaka. Zipangizo zakunja ziyenera kumangidwa kuti zipirire nyengo yovuta, pomwe zipangizo zamkati zimafunikira njira zapamwamba zozimitsira moto ndi mpweya wabwino.
Mayendedwe: Popeza ndi aakulu komanso olemera, kunyamula ma transformer awa kupita kumalo akutali komanso amapiri a damu ndi ntchito yaikulu kwambiri yokonza zinthu.
Kuchulukanso ndi Kudalirika: Monga gawo limodzi lolephera, kudalirika kwa transformer ya jenereta (GSU) ndikofunikira kwambiri. Mafakitale ambiri ali ndi makina odulira opangidwa mwaluso kapena transformer yowonjezera pamalopo kuti achepetse nthawi yogwira ntchito panthawi yokonza kapena kulephera.
Kupitirira Jenereta: Zosinthira Zina mu Chomera
Ngakhale kuti transformer yaikulu ndiyo nyenyezi ya chiwonetserochi, malo opangira magetsi amadalira banja lonse la ma transformer:
Ma Transformers Othandizira pa Siteshoni: "Ma transformers othandizira" awa amatsitsa mphamvu yamagetsi yapamwamba kupita ku milingo yotsika (monga, 480V) kuti apatse mphamvu makina ofunikira a fakitaleyo—magetsi, makina owongolera, mapampu oziziritsira, ndi ma mota a chipata.
Ma Transformers Othandizira a Unit: Izi zimalumikizidwa mwachindunji ndi mphamvu ya jenereta ndipo zimapereka mphamvu makamaka pamakina othandizira a chipangizocho.
Mapeto
Chosinthira magetsi chamadzi ndi ntchito yodziwika bwino ya uinjiniya wamagetsi, chinthu chofunikira komanso champhamvu chomwe chimagwira ntchito ngati chipata pakati pa kupanga ndi kugwiritsa ntchito. Popanda mphamvu yake yowonjezera mphamvu yamagetsi bwino, mphamvu yoyera, yobwezerezedwanso yochokera ku mitsinje ndi madamu singafikire mizinda ndi mafakitale omwe amadalira mphamvuyo. Chimayimira umboni wa chete komanso wamphamvu wa luso lofunikira kuti dziko lathu lamakono lizigwira ntchito mokhazikika.
