1.Types uye maitiro ekushanda kwejenereta
Jenareta mudziyo unogadzira magetsi kana waiswa pasimba remagetsi.Muchiitiko ichi chekushandura, simba remagetsi rinobva kune dzimwe nzira dzakasiyana-siyana dzesimba, dzakadai semhepo yemhepo, simba remvura, simba rekupisa, simba rezuva nezvimwe zvakadaro.Zvinoenderana nemhando dzakasiyana dzemagetsi, majenareta anonyanya kukamurwa kuita DC jenareta uye AC jenareta.
1. Maitiro anoshanda eDC jenareta
DC jenareta ine hunhu hwekushandisa nyore uye kushanda kwakavimbika.Inogona kupa zvakananga simba remagetsi kune ese marudzi emagetsi emidziyo inoda DC magetsi.Nekudaro, kune ino commutator mukati meDC jenareta, iri nyore kugadzira magetsi spark uye yakaderera simba kugadzirwa kwemagetsi.DC jenareta inogona kazhinji kushandiswa seDC magetsi emagetsi eDC mota, electrolysis, electroplating, kuchaja uye kunakidzwa kwealternator.
2. Maitiro ekushanda kwealternator
AC jenareta inoreva jenareta inogadzira AC pasi pekuita kwekunze kwemagetsi simba.Iri rudzi rwejenareta rinogona kukamurwa kuita synchronous AC simba rekugadzira
Synchronous jenareta ndiyo inonyanya kuzivikanwa pakati pe AC jenareta.Iri rudzi rwejenareta rinonakidzwa neDC ikozvino, iyo inogona kupa ese ari kushanda simba uye reactive simba.Inogona kushandiswa kugovera magetsi kune akasiyana michina yekutakura inoda AC magetsi.Uye zvakare, zvinoenderana neakasiyana ekutanga movers anoshandiswa, synchronous jenareta anogona kukamurwa kuita steam turbine jenareta, hydro jenareta, dhiziri jenareta uye mhepo turbine.
Alternators anoshandiswa zvakanyanya, semuenzaniso, majenareta anoshandiswa kupa magetsi munzvimbo dzakasiyana siyana dzemagetsi, mabhizinesi, zvitoro, imba yekumira yemagetsi magetsi, mota, nezvimwe.
Model uye tekinoroji paramita yejenareta
Kuti tifambise manejimendi ekugadzira uye kushandiswa kwejenareta, nyika yakabatanidza nzira yekubatanidza yemhando yejenareta, uye yakanamatira jenareta nameplate panzvimbo iri pachena yegoko rayo, iro rinonyanya kusanganisira modhi yejenareta, rated voltage, rated simba. kugovera, rated simba, insulation giredhi, frequency, simba chinhu uye kumhanya.
Muenzaniso uye zvinoreva jenareta
Iyo modhi yejenareta kazhinji inotsanangurwa yemuenzaniso weyuniti, kusanganisira rudzi rwemagetsi anobuda nejenareta, rudzi rwejenareta unit, maitiro ekudzora, dhizaini serial nhamba uye hunhu hwezvakatipoteredza.
Uye zvakare, iwo mamodheru emamwe majenareta ane hunyanzvi uye ari nyore, izvo zviri nyore kuziva, sezvakaratidzwa mumufananidzo 6, kusanganisira nhamba yechigadzirwa, yakayerwa voltage uye yakayerwa ikozvino.
(1) Rated voltage
Rated voltage inoreva iyo yakayerwa voltage inobuda nejenareta panguva yakajairika kushanda, uye unit iri kV.
(2) Yakatemerwa ikozvino
Yakatemerwa ikozvino inoreva iyo yakanyanya kushanda ikozvino yejenareta pasi peyakajairika uye inoenderera kushanda, muKa.Kana mamwe maparamita ejenareta akatarwa, jenareta inoshanda panguva ino, uye kukwira kwekushisa kweiyo stator winding hakuzopfuure muganhu unobvumirwa.
(3) Kutenderera kumhanya
Kumhanya kwejenareta kunoreva kukurumidza kutenderera kweiyo shaft huru yejenareta mukati me1min.Iyi parameter ndeimwe yeakakosha paramita kutonga kushanda kwejenareta.
(4) Kuwanda
Frequency inoreva kudzokororwa kwenguva ye AC sine wave mujenareta, uye chikamu chayo iHertz (Hz).Semuyenzaniso, kana frequency yejenareta iri 50Hz, inoratidza kuti kutungamira kwealternating current uye mamwe ma parameter 1s anochinja ka50.
(5) Simba chinhu
Jenareta inogadzira magetsi nemagetsi ekushandura, uye simba rayo rekubuda rinogona kukamurwa kuita marudzi maviri: reactive simba uye rinoshanda simba.Reactive simba rinonyanya kushandiswa kugadzira magineti uye kushandura magetsi uye magineti;Simba rinoshanda rinopiwa vashandisi.Mune simba rose rinobuda mujenareta, chikamu chesimba rinoshanda ndiro simba rekuita.
(6) Stator connection
Iyo stator yekubatanidza jenareta inogona kukamurwa kuva mhando mbiri, dzinoti triangular (△ shaped) connection uye nyeredzi (Y-shaped) connection, sezvinoratidzwa mumufananidzo 9. Mujenereta, mhepo mitatu yejenereta stator inowanzobatanidzwa mu star.
(7) Kirasi yekudzivirira
Iyo insulation giredhi rejenareta rinonyanya kureva iyo yakakwirira tembiricha yekudzivirira giredhi reiyo insulation zvinhu.Mune jenareta, iyo insulating zvinhu isimba risina simba.Izvo zvinhu zviri nyore kukurumidza kuchembera uye kunyange kukuvadza pakupisa kwakanyanya, saka giredhi rekudzivirira kupisa kwezvinhu zvakasiyana-siyana zvekudzivirira rakasiyanawo.Iyi parameter inowanzomiririrwa nemavara, apo y anoratidza kuti tembiricha isingadziviriri inosvika 90 ℃, a inoratidza kuti tembiricha isingadziviriri i105 ℃, e inoratidza kuti tembiricha isingaite kupisa i120 ℃, B inoratidza kuti kupisa. -isingaite tembiricha i130 ℃, f inoratidza kuti tembiricha isingadziviriri i155 ℃, H inoratidza kuti tembiricha isingaite i180 ℃, uye C inoratidza kuti tembiricha isingaite kupisa inodarika 180 ℃.
(8) Zvimwe
Mujenareta, kunze kweiyo yepamusoro petekinoroji parameters, kune zvakare maparamita akadai senhamba yezvikamu zvejenareta, huremu hwese hweyuniti uye zuva rekugadzira.Aya ma paramita ane intuitive uye ari nyore kunzwisisa kana uchiverenga, uye anonyanya kuitirwa vashandisi kuti vataure kana vachishandisa kana kutenga.
3, Symbol kuzivikanwa kwejenareta mumutsara
Jenareta chimwe chezvinhu zvakakosha mukudzora maseketi senge electric drive uye muchina chishandiso.Paunenge uchidhirowa dhiyabhorosi inoenderana nedunhu rega rega rekutonga, jenareta hairatidzirwe nechimiro chayo chaicho, asi inocherechedzwa nemifananidzo kana dhayagiramu, mavara uye zvimwe zviratidzo zvinomiririra basa rayo.
