Nheyo yekudzora otomatiki majenareta emotokari
Nheyo yekudzora otomatiki yemajenareta emotokari inonyanya kuita kuti voltage igare zvakanaka kuburikidza ne electromagnetic induction uye magnetic field current control. Inotevera ndiyo nzira chaiyo:
Maitiro ekudzora kupinza kwemagetsi
Jenareta inogadzirisa otomatiki kugadzirwa kwemagetsi ayo zvichienderana nekudiwa kwemagetsi. Kana simba rebhatiri risina kukwana kana midziyo yemagetsi ine simba guru ikashandiswa, jenareta inowedzera kugadzirwa kwemagetsi nekuwedzera simba remagetsi. Kana bhatiri razara, simba remagetsi rinodzikiswa otomatiki, zvichingochengetedza simba remagetsi.
Nheyo yekudzora voltage
Kuyerera kwemagineti kunochinjwa nekuchinja otomatiki simba remagetsi kuti ive nechokwadi chekuti magetsi anobuda agadzikana. Kana kumhanya kwemagetsi kwejenareta kuchichinja, zvichikonzera kuchinja kwemagetsi, regulator inoona chiratidzo chisina kujairika uye inogadzirisa simba remagetsi nekushandura simba remagetsi, nokudaro ichidzorera simba remagetsi kuhuwandu hwakatarwa. Semuenzaniso, kana kumhanya kwemagetsi kuchikwira, deredza simba remagetsi kuti udzivise overvoltage; kana kumhanya kwemagetsi kuchiderera, wedzera simba remagetsi kuti uchengetedze kugadzikana kwemagetsi.
Mhando dzakasiyana dzevatongi
Youdaoplaceholder0 relay regulator : Nekudzora kudzima kwemacontacts erelay kuti adzore magnetic field circuit, automatic voltage regulation inowanikwa.
Youdaoplaceholder0 Vatongi vemagetsi (vakadai serudzi rwekugadzika kwemukati/rudzi rwekugadzika kwekunze): Vanoshandisa zvikamu zvakaita sematransistors uye madiode ekusimbisa voltage kudzora simba remagetsi kuburikidza necircuit on-off.
Sisitimu iyi inogona kuyera kugadzirwa kwemagetsi nekudiwa kwemagetsi zvinobudirira, kudzivirira kutambisa simba uye kuwedzera hupenyu hwekushanda kwemidziyo.
Jenareta yemota ndiyo inonyanya kushandisa simba remota. Basa rayo nderekupa simba kumidziyo yese yemagetsi (kunze kwestarter) injini ichishanda zvakanaka, uye panguva imwe chete ichichaja bhatiri.
Zvichibva pakushandisa stator winding yezvikamu zvitatu ye common alternator, huwandu hwekutenderera kwe winding hunowedzerwa uye ma connection terminals anotungamirwa kunze, uye seti ye three-phase bridge rectifier inowedzerwa. Pakumhanya kwakaderera, winding yekutanga ne winding yakawedzerwa zvinobuda zvakatevedzana, nepo pakumhanya kwakakwira, winding yekutanga yezvikamu zvitatu chete ndiyo inobuda.
Nheyo yekushanda kwe alternator yese
Kana dunhu rekunze rikapa simba kutenderedzwa kwemhepo kuburikidza nebhurashi, simba remagineti rinogadzirwa, richiisa magineti pamatanda eclaw mumatanda eN nematanda eS. Kana rotor ikatenderera, magnetic flux inochinja-chinja mumatanho estator. Zvichienderana nepfungwa ye electromagnetic induction, alternating induced electromotive forces inogadzirwa mumatanho matatu estator. Iyi ndiyo nheyo yekugadzira simba re alternator.
Rotor yejenareta reDC excited synchronous inofambiswa ne prime mover (kureva, injini) kuti itenderere nekumhanya kwe n(rpm), uye three-phase stator winding inokonzera alternating current potential. Kana stator winding yakabatana ne electrical load, mota ichaburitsa alternating current. Alternating current inoshandurwa kuita direct current kuburikidza ne rectifier bridge mukati mejenareta uye yozobuda kubva ku output terminal.
Alternator yakakamurwa kuita zvikamu zviviri: stator winding uye rotor winding. Ma three-phase stator windings anogoverwa pa casing pa electrical Angle ye 120 degrees kune mumwe nemumwe, uye rotor winding ine pole claws mbiri. Kana rotor winding yakabatana ne direct current, inoshamiswa, uye pole mbiri dzinoumba N pole ne S pole. Magnetic field lines inotanga kubva paN pole, inopfuura nepakati pemhepo ichipinda mu stator core yozodzokera kuS pole iri pedyo. Kana rotor yangotenderera, rotor winding ichacheka magnetic field lines, ichigadzira sinusoidal electromotive force mu stator winding iyo inosiyana ne 120 degrees of electrical degree, kureva, three-phase alternating current, iyo inozoshandurwa kuita direct current output ne rectifier element inoumbwa nema diodes.
Kana switch yavharwa, magetsi anotanga apihwa nebhatiri. Sekeri yacho ndeiyi:
Chinogumira zvakanaka chebhatiri → mwenje wekuratidza kuchaja → kubatana kwemutongi → kutenderera kwemhepo → kudzika kwebhatiri → chigadziko chisina kunaka. Panguva ino, mwenje wekuratidza kuchaja uchabatidzwa nekuti pane magetsi anopfuura nepakati pawo.
Zvisinei, mushure mekunge injini yatanga, sezvo kumhanya kwejenareta kuchikwira, voltage yemagetsi yejenareta inoramba ichikwirawo. Kana voltage inobuda yejenareta yakaenzana neyebhatiri, simba remagetsi pa "B" ne "D" terminals yejenareta rakafanana. Panguva ino, mwenje wechiratidzo chekuchaja unodzima nekuda kwekusawirirana kwesimba pakati pemativi maviri. Izvi zvinoratidza kuti jenareta iri kushanda zvakanaka uye simba remagetsi rinopihwa nejenareta pachayo. Simba remagetsi remagetsi remaphase matatu rinogadzirwa nemhepo inotenderera mujenareta rinogadziriswa ne diode uye rinoburitsa simba remagetsi zvakananga kuti ripe simba kumutoro uye richaje bhatiri.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
