Mfundo yoyendetsera majenereta a magalimoto yokha
Mfundo yoyendetsera yokha ya majenereta a magalimoto makamaka imakwaniritsa kukhazikika kwa magetsi kudzera mu induction yamagetsi ndi kuwongolera mphamvu yamagetsi. Njira yake ndi iyi:
Njira yoyendetsera kayendetsedwe ka magetsi
Jenereta imasintha yokha kupanga magetsi ake malinga ndi kufunikira kwa magetsi. Ngati mphamvu ya batri sikokwanira kapena zipangizo zamagetsi zamagetsi zimagwiritsidwa ntchito, jenereta imawonjezera kupanga magetsi mwa kuwonjezera mphamvu ya maginito. Batire ikadzaza ndi mphamvu, mphamvu ya maginito imachepa yokha, zomwe zimangosunga kufunikira kwa mphamvu yoyambira.
Mfundo yoyendetsera magetsi
Mphamvu ya maginito imasinthidwa yokha posintha mphamvu ya maginito kuti zitsimikizire kuti mphamvu yotulutsa ikuyenda bwino. Pamene liwiro lozungulira la jenereta likusintha, zomwe zimapangitsa kuti magetsi azisinthasintha, wowongolerayo amazindikira chizindikiro chosazolowereka ndikusintha mphamvu ya mphamvu ya maginito mwa kusintha mphamvu yotulutsa, potero amabwezeretsa mphamvuyo ku mtundu wokhazikitsidwa. Mwachitsanzo, pamene liwiro lozungulira likuwonjezeka, chepetsani mphamvu yotulutsa kuti mupewe kupitirira muyeso wamagetsi; pamene liwiro lozungulira likuchepa, onjezerani mphamvu yotulutsa kuti musunge kukhazikika kwa magetsi.
Mitundu yosiyanasiyana ya owongolera
Wowongolera ma relay a Youdaoplaceholder0 : Mwa kuwongolera kuyatsidwa kwa ma contacts a relay kuti ayendetse dera la maginito, malamulo amagetsi odziyimira pawokha amakwaniritsidwa.
Youdaoplaceholder0 Owongolera zamagetsi (monga mtundu wa nthaka yamkati/mtundu wa nthaka yakunja): Amagwiritsa ntchito zigawo monga ma transistors ndi ma diode okhazikika a voltage kuti azitha kuwongolera mphamvu yamagetsi yamagetsi kudzera mu circuit on-off.
Dongosololi lingathe kulinganiza bwino kupanga magetsi ndi kufunikira kwa magetsi, kupewa kuwononga mphamvu ndikuwonjezera nthawi yogwiritsira ntchito zida.
Jenereta ya galimoto ndiye gwero lalikulu la mphamvu ya galimoto. Ntchito yake ndikupereka mphamvu ku zipangizo zonse zamagetsi (kupatula choyatsira) pamene injini ikugwira ntchito bwino, komanso nthawi yomweyo kuyatsa batri.
Kutengera ndi kuzungulira kwa stator kwa magawo atatu kwa alternator wamba, kuchuluka kwa kuzungulira kwa kuzungulira kumawonjezeka ndipo malo olumikizira amatsogozedwa kunja, ndipo seti ya rectifier ya magawo atatu imawonjezedwa. Pa liwiro lotsika, kuzungulira koyambirira ndi kuzungulira kowonjezera kumatulutsidwa motsatizana, pomwe pa liwiro lokwera, kuzungulira koyambirira kwa magawo atatu kokha ndiko komwe kumatuluka.
Mfundo yogwirira ntchito ya alternator yonse
Pamene dera lakunja limapereka mphamvu kuzunguliridwa kwa chisangalalo kudzera mu burashi, mphamvu ya maginito imapangidwa, zomwe zimapangitsa kuti mitengo ya claw ikhale ya N ndi S. Rotor ikazungulira, mphamvu ya maginito imasintha mosinthana mu stator windings. Malinga ndi mfundo ya electromagnetic induction, mphamvu zamagetsi zomwe zimapangidwa mosinthana zimapangidwa mu three-phase windings ya stator. Iyi ndi mfundo yopanga mphamvu ya alternator.
Chozungulira cha jenereta ya DC excited synchronous chimayendetsedwa ndi prime mover (mwachitsanzo, injini) kuti chizungulire pa liwiro la n(rpm), ndipo chozungulira cha stator cha magawo atatu chimayambitsa mphamvu ya alternating current. Ngati chozungulira cha stator chalumikizidwa ndi katundu wamagetsi, motayo imatulutsa alternating current. Alternating current imasinthidwa kukhala direct current kudzera mu rectifier bridge mkati mwa jenereta kenako n’kutuluka kuchokera ku output terminal.
Alternator imagawidwa m'magawo awiri: stator winding ndi rotor winding. Ma stator winding a magawo atatu amagawidwa pa casing pa ngodya yamagetsi ya madigiri 120 kwa wina ndi mnzake, ndipo rotor winding imapangidwa ndi zikhadabo ziwiri za pole. Rotor winding ikalumikizidwa ku direct current, imalimbikitsidwa, ndipo pole ziwirizo zimapanga N pole ndi S pole. Mizere ya maginito imayamba kuchokera ku N pole, imadutsa mumpata wa mpweya kupita ku stator core kenako imabwerera ku S pole yoyandikana nayo. Rotor ikangozungulira, rotor winding imadula mizere ya maginito, ndikupanga mphamvu ya sinusoidal electromotive mu stator winding yomwe imasiyana ndi madigiri 120 a electrical degree, ndiko kuti, three-phase alternating current, yomwe imasinthidwa kukhala direct current output ndi rectifier element yopangidwa ndi ma diode.
Chosinthira chikatsekedwa, mphamvu yamagetsi imaperekedwa koyamba ndi batire. Setiyiti ndi:
Choyimilira chabwino cha batire → chowunikira chowunikira chochaja → cholumikizira chowongolera → chozungulira chotsitsimula → choyimitsa → choyimitsa pansi → choyimilira choipa cha batire. Pa nthawiyi, chowunikira chowunikira chowunikira chidzayatsa chifukwa pali magetsi omwe akudutsamo.
Komabe, injini ikayamba, pamene liwiro la jenereta likukwera, mphamvu ya magetsi ya jenereta imapitirira kukwera. Mphamvu ya magetsi yotuluka ya jenereta ikafanana ndi ya batri, mphamvu ya magetsi pa ma terminal a "B" ndi "D" a jenereta imakhala yofanana. Panthawiyi, kuwala kwa chizindikiro chochaja kumazimitsidwa chifukwa cha kusiyana kwa mphamvu pakati pa malekezero awiri. Zimasonyeza kuti jenereta ikugwira ntchito bwino ndipo mphamvu yamagetsi imaperekedwa ndi jenereta yokha. Mphamvu yamagetsi yamagetsi ya magawo atatu yomwe imapangidwa ndi kuzungulira kwa magawo atatu mu jenereta imakonzedwa ndi diode kenako imatulutsa mphamvu yamagetsi mwachindunji kuti ipereke mphamvu ku katundu ndikuchaja batri.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
