Mitundu Yoperekera Mphamvu ya AC mu Machitidwe Ogawa

Mu machitidwe amagetsi amakono,gawo logawaimagwira ntchito ngati mlatho wofunikira kwambiri wolumikiza ma gridi amphamvu ambiri ndi ogwiritsa ntchito kumapeto. Kukhazikika ndi kugwira ntchito bwino kwa machitidwe ogawa magetsi kumatsimikizira mwachindunji kugwiritsa ntchito bwino mphamvu ndi chitetezo chamagetsi, zomwe zimayambitsa kupanga mafakitale, ntchito za m'mizinda, komanso moyo watsiku ndi tsiku wokhala. Monga kampani yotsogola mu mayankho anzeru a gridi, PEOPLE yakhala ikupititsa patsogolo kusintha kwa njira zogawa magetsi kudzera muukadaulo watsopano, kupereka chithandizo champhamvu pakusintha kwa mphamvu padziko lonse lapansi. Nkhaniyi imafotokoza mwatsatanetsatane ndikufotokozera njira zosiyanasiyana zamagetsi osinthira magetsi (AC) omwe amagwiritsidwa ntchito m'makina ogawa magetsi.

Mitundu Yoperekera Mphamvu ya AC: Kusinthasintha ndi Kuchita Bwino Monga Msana wa Ma Gridi Amphamvu Amakono

Mphamvu yamagetsi yosinthira magetsi (AC) yadzikhazikitsa yokha ngati yankho lalikulu m'machitidwe amakono ogawa magetsi, chifukwa cha zabwino zake zomwe zimaphatikizapo kukweza mphamvu yamagetsi mosavuta, kugwiritsa ntchito bwino mphamvu yamagetsi mtunda wautali, komanso ndalama zochepa zogwirira ntchito ndi zida zamagetsi zogwirizana nazo. Pogawika m'magulu malinga ndi kuchuluka kwa magetsi ndi mawaya, machitidwe amagetsi a AC amagawidwa m'magulu otsatirawa:

Dongosolo la Mawaya Atatu la Gawo Litatu

Kapangidwe kameneka kamathandiza kuti mphamvu zamagetsi zitatu zamagetsi zifalikire bwino kwambiri kudzera mu kulumikizana kwa delta (△) kapena ma topology olumikizirana ndi nyenyezi (Y). Ndi kapangidwe kosavuta komanso mawonekedwe okhazikika a mphamvu yotulutsa, imagwira ntchito kokha pazochitika zokhudzana ndikatundu wolinganizidwa wa magawo atatuImagwiritsidwa ntchito kwambiri m'maukonde ogawa magetsi amphamvu (monga machitidwe a 35kV–60kV), makonzedwe a magalimoto a mafakitale, ndi makina akuluakulu owunikira mafakitale/malonda.

Dongosolo la Mawaya Anayi la Gawo Litatu

Dongosololi, lomwe lili ndi ma conductor atatu (mawaya amoyo) ndi conductor imodzi yopanda mbali, limapereka mphamvu yamagetsi yosakanikirana ya 380V/220V. Lili ndi kusinthasintha kwapadera kogwira ntchito, komwe kumatha kukwaniritsa nthawi imodzi kufunikira kwa mphamvu ya zida zamphamvu zitatu (zomwe zimagwira ntchito pa 380V) ndi katundu wamagetsi ochepa (wogwira ntchito pa 220V). Njirayi imagwiritsidwa ntchito padziko lonse lapansi m'malo osakanikirana ogawa magetsi otsika kuti agwiritsidwe ntchito ndi magetsi, ndi ntchito zazikulu zomwe zimafikira m'nyumba zogona, m'malo ogulitsira, m'malo ogwirira ntchito m'mizinda, komanso m'malo ochitira misonkhano yamafakitale.

Dongosolo la Mawaya Awiri la Gawo Limodzi

Kapangidwe kake koyambira kali ndi kondakitala imodzi yokha ya gawo ndi kondakitala imodzi yopanda mbali, yomwe imapereka mphamvu yokhazikika ya 220V ya gawo limodzi. Ili ndi ndalama zochepa zomangira, kukhazikitsa mawaya kosavuta, komanso kugwiritsa ntchito bwino komanso kukonza, komabe imaletsedwa ndi mphamvu zochepa zonyamulira katundu. Imagwiritsidwa ntchito kwambiri poyatsira magetsi m'nyumba, zida zazing'ono zapakhomo, komanso zida zamaofesi za gawo limodzi zopanda mphamvu zambiri.

Makonzedwe Ena Apadera

Njira Yobwezeretsanso Mawaya Awiri ya Gawo Litatu: Yomwe idagwiritsidwa ntchito kale m'malo ogawa magetsi akumidzi, njira iyi yakhala ikuchepetsedwa pang'onopang'ono m'makina amagetsi amakono chifukwa cha kusowa kwa chitetezo chamagetsi, kudalirika kwa magwiridwe antchito, komanso mtundu wamagetsi.

Dongosolo la Waya Limodzi la Magawo Atatu: Kapangidwe kapadera kopangidwira magetsi ogwiritsira ntchito njanji yamagetsi, ndipo makina amagetsi ogwiritsira ntchito waya umodzi a 27.5kV ndi omwe amagwiritsidwa ntchito kwambiri pa njanji zamagetsi ndi maukonde a sitima zachangu.
