1. Mitundu ndi machitidwe a jenereta
Jenereta ndi chipangizo chomwe chimapanga magetsi chikagwidwa ndi mphamvu zamakina.Pakutembenuka uku, mphamvu yamakina imachokera ku mitundu yosiyanasiyana ya mphamvu, monga mphamvu ya mphepo, mphamvu ya madzi, mphamvu ya kutentha, mphamvu ya dzuwa ndi zina zotero.Malinga ndi mitundu yosiyanasiyana yamagetsi, ma jenereta amagawidwa kukhala majenereta a DC ndi ma generator a AC.
1. Makhalidwe ogwira ntchito a jenereta ya DC
Jenereta ya DC ili ndi mawonekedwe ogwiritsa ntchito mosavuta komanso odalirika.Itha kupereka mwachindunji mphamvu yamagetsi yamitundu yonse yazida zamagetsi zomwe zimafunikira magetsi a DC.Komabe, pali chosinthira mkati mwa jenereta ya DC, yomwe ndi yosavuta kutulutsa magetsi komanso mphamvu zochepa zopangira mphamvu.Jenereta ya DC imatha kugwiritsidwa ntchito ngati magetsi a DC a mota ya DC, electrolysis, electroplating, kulipiritsa komanso kusangalatsa kwa alternator.
2. Makhalidwe amachitidwe a alternator
Jenereta ya AC imatanthawuza jenereta yomwe imapanga AC pansi pa mphamvu yakunja yamakina.Mtundu uwu wa jenereta ukhoza kugawidwa mu synchronous AC mphamvu yamagetsi
Jenereta ya Synchronous ndiyomwe imapezeka kwambiri pakati pa ma generator a AC.Jenereta yamtunduwu imakondwera ndi DC yamakono, yomwe imatha kupereka mphamvu zonse zogwira ntchito komanso mphamvu zogwira ntchito.Itha kugwiritsidwa ntchito popereka mphamvu ku zida zosiyanasiyana zonyamula zomwe zimafunikira magetsi a AC.Kuphatikiza apo, malinga ndi ma movers oyambira omwe amagwiritsidwa ntchito, ma jenereta olumikizana amatha kugawidwa kukhala ma generator a turbine, ma hydro jenereta, majenereta a dizilo ndi ma turbine amphepo.
Ma alternators amagwiritsidwa ntchito kwambiri, mwachitsanzo, ma jenereta amagwiritsidwa ntchito popangira magetsi m'malo osiyanasiyana opangira magetsi, mabizinesi, mashopu, magetsi oyimira nyumba, magalimoto, ndi zina zambiri.
Model ndi luso magawo jenereta
Kuti atsogolere kasamalidwe kupanga ndi kugwiritsa ntchito jenereta, boma linagwirizanitsa njira kaphatikizidwe chitsanzo jenereta, ndipo anaika jenereta nameplate pa malo zoonekeratu chipolopolo chake, makamaka zikuphatikizapo jenereta chitsanzo, oveteredwa voteji, oveteredwa mphamvu. kupezeka, mphamvu zovoteledwa, kalasi yotsekera, ma frequency, mphamvu ndi liwiro.
Chitsanzo ndi tanthauzo la jenereta
Chitsanzo cha jenereta nthawi zambiri chimafotokoza za chitsanzo cha unit, kuphatikizapo mtundu wa magetsi opangidwa ndi jenereta, mtundu wa jenereta, makhalidwe olamulira, chiwerengero cha seriyoni ndi chilengedwe.
Kuonjezera apo, zitsanzo za majenereta ena ndizowoneka bwino komanso zosavuta, zomwe zimakhala zosavuta kuzizindikira, monga momwe tawonetsera pa Chithunzi 6, kuphatikizapo chiwerengero cha mankhwala, magetsi ovotera ndi oveteredwa panopa.
(1) Mphamvu yamagetsi
Mphamvu yamagetsi imatanthawuza kutulutsa kwamagetsi kwa jenereta panthawi yogwira ntchito bwino, ndipo gawolo ndi kV.
(2) Zovoteledwa panopa
Zovoteledwa panopa zimatanthawuza kuchuluka kwa ntchito kwa jenereta pansi pa ntchito yachibadwa komanso mosalekeza, mu Ka.Pamene magawo ena a jenereta adavotera, jenereta imagwira ntchito panthawiyi, ndipo kutentha kwa mpweya wake wa stator sikudzapitirira malire ovomerezeka.
(3) Liwiro lozungulira
Kuthamanga kwa jenereta kumatanthawuza kuthamanga kwakukulu kozungulira kwa shaft yaikulu ya jenereta mkati mwa 1min.Izi parameter ndi imodzi mwamagawo ofunikira kuweruza ntchito ya jenereta.
(4) pafupipafupi
Frequency imatanthawuza kubwereza kwa nthawi ya AC sine wave mu jenereta, ndipo gawo lake ndi Hertz (Hz).Mwachitsanzo, ngati mafupipafupi a jenereta ndi 50Hz, zikusonyeza kuti malangizo a alternating panopa ndi magawo ena 1s kusintha 50 nthawi.
(5) Mphamvu yamagetsi
Jenereta imapanga magetsi ndi kutembenuka kwa electromagnetic, ndipo mphamvu yake yotulutsa imatha kugawidwa m'mitundu iwiri: mphamvu yogwira ntchito ndi mphamvu yogwira ntchito.Mphamvu yokhazikika imagwiritsidwa ntchito makamaka popanga maginito ndikutembenuza magetsi ndi maginito;Mphamvu yogwira ntchito imaperekedwa kwa ogwiritsa ntchito.Mu mphamvu yonse yamagetsi a jenereta, gawo la mphamvu yogwira ntchito ndilo mphamvu yamagetsi.
(6) Kulumikizana kwa Stator
Kulumikizana kwa stator kwa jenereta kungathe kugawidwa m'mitundu iwiri, kugwirizana kwa triangular (△ mawonekedwe) ndi kugwirizana kwa nyenyezi (monga Y), monga momwe tawonetsera pa Chithunzi 9. nyenyezi.
(7) Kalasi ya insulation
The kutchinjiriza kalasi ya jenereta makamaka amatanthauza mkulu kutentha kukana kalasi yake kutchinjiriza zakuthupi.Mu jenereta, zinthu zotetezera ndizopanda mphamvu.Zinthuzo ndizosavuta kufulumizitsa ukalamba komanso kuwonongeka pakutentha kwambiri, kotero kuti kalasi yolimbana ndi kutentha kwazinthu zosiyanasiyana zotsekera ndizosiyana.Chizindikirochi nthawi zambiri chimayimiridwa ndi zilembo, pomwe y akuwonetsa kuti kutentha kosagwira kutentha ndi 90 ℃, akuwonetsa kuti kutentha kosagwira ndi 105 ℃, e kumasonyeza kuti kutentha kosagwira ndi 120 ℃, B kumasonyeza kuti kutentha. -Kutentha kosamva kutentha ndi 130 ℃, f kumasonyeza kuti kutentha kosagwira kutentha ndi 155 ℃, H kumasonyeza kuti kutentha ndi 180 ℃, ndipo C kumasonyeza kuti kutentha kosagwira kutentha kumapitirira 180 ℃.
(8) Zina
Mu jenereta, kuwonjezera pazigawo zaukadaulo zomwe zili pamwambazi, palinso magawo monga kuchuluka kwa magawo a jenereta, kulemera kwathunthu kwa unit ndi tsiku lopanga.Izi ndizomveka komanso zosavuta kuzimvetsetsa powerenga, ndipo ndizofunikira kwa ogwiritsa ntchito kuti azigwiritsa ntchito kapena pogula.
3, Chizindikiro cha jenereta pamzere
Jenereta ndi chimodzi mwazinthu zofunika kwambiri pakuwongolera mabwalo monga magetsi oyendetsa ndi chida cha makina.Pojambula chojambula chojambula chogwirizana ndi dera lililonse lolamulira, jeneretayo siiwonetsedwa ndi mawonekedwe ake enieni, koma imadziwika ndi zojambula kapena zojambula, zilembo ndi zizindikiro zina zoimira ntchito yake.
