Pankhani ya uinjiniya wamagetsi, ma transfoma amatenga gawo lofunikira pakufalitsa ndi kugawa mphamvu zamagetsi. Pakati pa mitundu yosiyanasiyana ya ma transformer, ma transformers amakono (CTs) ndi magetsi (PTs) ndi awiri omwe amagwiritsidwa ntchito kwambiri. Ngakhale kuti mayina awo ndi ofanana, amagwira ntchito zosiyanasiyana ndipo ndi ofunikira kuzinthu zosiyanasiyana zamagetsi. Nkhaniyi ikufotokoza zomwe ma transformer amakono ndi magetsi amagwiritsidwa ntchito, ndikuwunikira cholinga chachikulu cha transformer yamakono.
Kodi aTransformer Yamakono?
Transformer yapano ndi mtundu wa chosinthira chida chomwe chimapangidwa kuti chiyezetse kusintha kwapano (AC). Zimagwira ntchito popanga kuchepetsedwa komwe kuli kofanana ndi komwe kukuchitika mderali, komwe kumatha kuyang'aniridwa ndikuyezedwa ndi zida zokhazikika. Ma CT ndi ofunikira pamikhalidwe yomwe milingo yomwe ilipo tsopano ndiyokwera kwambiri kuti isayesedwe mwachindunji ndi zida wamba.
Cholinga Chachikulu cha Transformer Yapano
Cholinga chachikulu cha transformer yamakono ndikuwongolera kuyeza kotetezeka ndi kuyang'anira mayendedwe apamwamba. Potsika pakali pano mpaka pamlingo wochepetsetsa, wokhoza kuyendetsedwa bwino, ma CT amalola kugwiritsa ntchito zida zoyezera komanso zotetezera. Izi ndizofunikira kwambiri pazifukwa zotsatirazi:
Chitetezo:Kuyeza mwachindunji mafunde okwera kungakhale koopsa. CTs imachepetsa zomwe zilipo panopa kuti zikhale zotetezeka, kuchepetsa chiopsezo kwa ogwira ntchito ndi zipangizo.
Kulondola:Ma CTs amapereka miyeso yolondola yapano, yomwe ndi yofunikira pakugwira ntchito moyenera kwa ma relay oteteza ndi zida zama metering.
Kudzipatula:Amapereka kudzipatula kwamagetsi pakati pa chigawo champhamvu chamagetsi ndi zida zoyezera, kuteteza zotsirizirazi ku mawotchi othamanga kwambiri.
Mapulogalamu a Current Transformers
Ma transformer apanoamagwiritsidwa ntchito kwambiri muzochita zosiyanasiyana, kuphatikizapo:
Chitetezo cha Power System:Ma CT ndi ofunikira pakugwira ntchito kwa ma relay oteteza, omwe amazindikira zolakwika ndikuyambitsa zosokoneza kuti azipatula magawo olakwika.
Kuyeza:Amagwiritsidwa ntchito mu mita ya mphamvu kuti ayese kuchuluka kwa mphamvu zamagetsi zomwe zimagwiritsidwa ntchito.
Kuyang'anira:Ma CT amathandizira kuyang'anira kayendedwe kake kachitidwe kamagetsi, kuthandizira kuzindikira zochulukira ndikuwonetsetsa kugawa mphamvu moyenera.
Kodi aMphamvu Transformer?
Komano, chosinthira mphamvu chamagetsi chimapangidwa kuti chisamutse mphamvu zamagetsi pakati pa mabwalo awiri kapena kupitilira apo kudzera mu induction yamagetsi. Zosintha zamagetsi zimagwiritsidwa ntchito kukweza (kuwonjezera) kapena kutsika (kuchepetsa) ma voliyumu pamakina amagetsi, kumathandizira kutumiza ndi kugawa mphamvu zamagetsi pamtunda wautali.
Cholinga Chachikulu cha Power Transformer
Cholinga chachikulu cha chosinthira mphamvu ndikupangitsa kuti mphamvu zamagetsi ziziyenda bwino kuchokera kumalo opangira zida kupita kwa ogwiritsa ntchito. Izi zikuphatikizapo:
Kuwongolera kwa Voltage: Zosintha zamagetsi zimasintha ma voliyumu kuti achepetse kutaya mphamvu pakutumiza. Ma voliyumu apamwamba amagwiritsidwa ntchito potumiza mtunda wautali kuti achepetse zomwe zikuchitika komanso, chifukwa chake, zotayika zokana.
Kugawa Katundu: Amathandizira kugawa katundu wamagetsi m'mabwalo osiyanasiyana, kuwonetsetsa kuti magetsi azikhala oyenera komanso okhazikika.
Kudzipatula: Zosintha zamagetsi zimapereka kudzipatula kwamagetsi pakati pa magawo osiyanasiyana amagetsi, kumapangitsa chitetezo ndi kudalirika.
Kugwiritsa Ntchito Ma Power Transformers
Zosintha zamagetsindizofunika kwambiri pamagawo osiyanasiyana amagetsi, kuphatikiza:
Ma Generation Stations: Amawonjezera mphamvu yamagetsi yopangidwa ndi magetsi kuti azitha kufalitsa mtunda wautali.
Masiteshoni: Magetsi osinthira magetsi m'malo ang'onoang'ono amatsitsa ma voltages okwera kwambiri kuti atsitse magawo oyenera kugawidwa m'nyumba ndi mabizinesi.
Kugwiritsa Ntchito Mafakitale: Amagwiritsidwa ntchito m'mafakitale kuti apereke ma voltage ofunikira pamakina ndi zida zosiyanasiyana.
Mapeto
Mwachidule, ma transfoma apano ndi ma transfoma amagetsi amagwira ntchito zosiyana koma zowonjezera pamakina amagetsi. Zosintha zamakono zimagwiritsidwa ntchito makamaka poyesa ndi kuyang'anira milingo yapamwamba yamakono mosamala komanso molondola, pamene zosintha zamagetsi ndizofunikira kuti pakhale kufalitsa ndi kugawa mphamvu zamagetsi. Kumvetsetsa ntchito ndikugwiritsa ntchito kwa ma transfomawa ndikofunikira kwa aliyense amene akuchita nawo uinjiniya wamagetsi.
