Pakadali pano, kusowa kwa magetsi padziko lonse lapansi kukukulirakulira. Makampani ambiri ndi anthu pawokha amasankha kugula ma jenereta kuti achepetse zoletsa pakupanga ndi moyo zomwe zimachitika chifukwa cha kusowa kwa magetsi. Alternator ya AC ndi gawo lofunika kwambiri pa jenereta yonse. Momwe mungasankhire ma alternator odalirika, malangizo otsatirawa ayenera kukumbukiridwa:
I. Makhalidwe amagetsi:
1. Dongosolo loyambitsa: Pa gawoli, dongosolo loyambitsa la alternator yapamwamba kwambiri ya AC ndi loyambitsa lokha, lomwe nthawi zambiri limakhala ndi chowongolera chamagetsi chodziyimira pawokha (AVR). Mphamvu yotulutsa ya rotor yoyambitsa imatumizidwa ku rotor yolandira kudzera mu rectifier. Kuchuluka kwa kusintha kwa magetsi kwa AVR nthawi zambiri kumakhala ≤1%. Pakati pawo, AVR yapamwamba kwambiri ilinso ndi ntchito zingapo monga kugwira ntchito motsatizana, kuteteza ma frequency otsika, ndi kusintha kwa magetsi akunja.
2. Kuteteza ndi kuphimba: Mtundu wa kutetezera wa ma alternator apamwamba nthawi zambiri umakhala wa gulu la "H", ndipo ziwalo zake zonse zozungulira zimapangidwa ndi zipangizo zopangidwa mwapadera ndipo zimadzazidwa ndi njira yapadera. Alternator imayenda m'malo ovuta kuti ipereke chitetezo.
3. Kupindika ndi magwiridwe antchito amagetsi: Stator ya alternator yapamwamba kwambiri idzapakidwa ndi mbale zachitsulo zozungulira zozizira zokhala ndi mphamvu zambiri zamaginito, zopindika ziwiri, kapangidwe kamphamvu komanso magwiridwe antchito abwino oteteza kutentha.
4. Kusokoneza kwa mafoni: THF (monga momwe tafotokozera mu BS EN 600 34-1) ndi yochepera 2%. TIF (monga momwe tafotokozera mu NEMA MG1-22) ndi yochepera 50
5. Kusokoneza wailesi: Zipangizo zapamwamba zopanda burashi ndi AVR zidzaonetsetsa kuti palibe kusokoneza kwakukulu panthawi yotumiza wailesi. Ngati pakufunika, chipangizo china choletsa RFI chikhoza kuyikidwa.
II. Makhalidwe a makina:
Mlingo wa chitetezo: Mitundu yodziwika bwino ya majenereta onse a AC okhala pamtunda ndi IP21, IP22 ndi IP23 (NEMA1). Ngati pali kufunika koteteza kwakukulu, mungasankhe kukweza mulingo wa chitetezo wa IP23. Mtundu wodziwika bwino wa jenereta ya AC yam'madzi ndi IP23, IP44, IP54. Ngati mukufuna kukweza mulingo wa chitetezo, monga chilengedwe chomwe chili m'mphepete mwa nyanja, mutha kupatsa jenereta ya AC zinthu zina zowonjezera, monga zotenthetsera m'mlengalenga, zosefera mpweya, ndi zina zotero.
Kusowa kwa magetsi padziko lonse kwawonjezera kwambiri malonda a ma alternator/majenereta a AC. Mitengo ya zowonjezera za majenereta a AC monga ma disc coupling ndi ma rotor yakwera kwambiri. Kupezeka kwa magetsi ndi kochepa. Ngati mukufuna magetsi, mutha kugula majenereta a AC mwachangu momwe mungathere. Mtengo wa majenereta a AC ukukweranso nthawi zonse!
