Jenareta yemotokari.
Jenareta yemotokari ndiyo inonyanya kupa simba mumotokari, basa rayo nderekupa simba kumidziyo yese yemagetsi (kunze kwestarter) kana injini ichishanda zvakanaka, uye kuchaja bhatiri panguva imwe chete.
Pachishandiswa common alternator three-phase stator winding, wedzera huwandu hwema winding turns uye lead out the terminal, wedzera seti ye three-phase bridge rectifier. Pakumhanya kwakaderera, primary winding uye extension winding zvinobuda zvakatevedzana, uye pakumhanya kwakakwirira, primary three-phase winding chete ndiyo inobuda.
Musimboti wekushanda
Nheyo yekushanda kwealternator yese
Kana dunhu rekunze rikapa simba kumunda unomonereka nebhurashi, simba remagineti rinogadzirwa, kuitira kuti claw pole ipinde muN pole neS pole. Kana rotor ikatenderera, magnetic flux inochinja-chinja mukumonereka kwestator, zvichienderana nepfungwa ye electromagnetic induction, stator three-phase winding ichaburitsa alternating induced electromotive force. Aya ndiwo magadzirirwo anoitwa magetsi ne alternator.
Iyo prime mover (kureva injini) inodhonza iyo DC excited synchronous generator rotor kuti itenderere pa speed n(rpm), uye iyo three-phase stator winding induction AC potential. Kana stator winding yakabatana ne electrical load, mota ine AC power output, uye AC power inoshandurwa kuita direct current kubva ku output terminal kuburikidza ne rectifier bridge mukati me generator.
Alternator yakakamurwa kuita zvikamu zviviri zvekutenderera kwe stator ne rotor, kutenderera kwe stator kwezvikamu zvitatu kunogoverwa pagoko zvichienderana ne electric Angle ye 120 degrees musiyano pakati peumwe neumwe, kutenderera kwe rotor kunoumbwa ne pole claws mbiri. Kana rotor winding yakabatana ne direct current, inofashukira, uye pole claws mbiri dzinoumba N pole ne S pole. Magnetic field line inotanga kubva pa N pole, inopinda mu stator core kuburikidza ne air gap uye inodzokera ku S pole iri pedyo. Kana rotor yangotenderedzwa, rotor winding inocheka magnetic force line, uye inoburitsa sinusoidal electromotive force ine musiyano we 120 degrees electrical Angle mu stator winding, kureva, three-phase alternating current, uye inobva yapinda mu rectifier element yakagadzirwa nema diodes kuita direct current output.
Kana switch yavharwa, bhatiri rinotanga rava nemagetsi. Sekeri yacho ndeiyi:
Bhatiri rakanaka → rambi rekuchaja → regulator contact → excitation winding → lap iron → bhatiri harina kunaka. Panguva ino, rambi rekuchaja richabatidzwa nekuda kwemagetsi anopinda nepakati.
Zvisinei, mushure mekunge injini yatanga, sezvo kumhanya kwejenareta kuchiwedzera, voltage yejenareta inowedzerawo. Kana voltage inobuda yejenareta yakaenzana nevoltage yebhatiri, potential ye "B" end ne "D" end yejenareta yakaenzana, panguva ino, mwenje wechiratidzo chekuchaja unodzimwa nekuti mutsauko uripo pakati pemagumo maviri izero. Zvinoratidza kuti jenareta iri kushanda zvakanaka uye excitation current inopihwa nejenareta pachayo. Simba remagetsi reAC rechikamu chechitatu rinogadzirwa ne three-phase winding mujenareta rinogadziriswa ne diode uye rinoburitsa direct current kuti ripe simba kumutoro uye richaje bhatiri.
Alternator inowanzo kuve nezvikamu zvina: rotor, stator, rectifier uye end cap.
(1) Rotor
Basa re rotor nderekugadzira simba remagineti rinotenderera.
Rotor ine danda reclaw, joko, magnetic field winding, collector ring uye rotor shaft.
Matanda maviri ezvipikiri anodzvanywa parotor shaft, uye rimwe nerimwe rematanda maviri ezvipikiri rine matanda matanhatu emagnetic ane muromo weshiri. Magnetic field winding (rotor coil) uye magnetic joke zvakarongwa mugomba rematanda ezvipikiri.
Mhete yekuunganidza ine mhete mbiri dzemhangura dzakadzivirirwa kubva kune imwe neimwe. Mhete yekuunganidza inodzvanywa parotor shaft uye inodzivirirwa neshaft. Mhete mbiri dzekuunganidza dzakabatana kumativi ese emagnetic field winding.
Kana mhete mbiri dzekuunganidza dzichipinda mu direct current (kuburikidza nebhurashi), pane magetsi kuburikidza ne magnetic field winding, uye axial magnetic flux inogadzirwa, zvekuti imwe claw pole inoiswa magneti ku N pole uye imwe inoiswa magneti ku S pole, nokudaro zvichiita mapeya matanhatu e magnetic poles akabatana. Sezvo rotor ichitenderera, magnetic field inotenderera inogadzirwa [1].
Dunhu remagineti re alternator ndeiri: yoka →N pole → mhepo pakati pe rotor ne stator → stator → mhepo pakati pe stator ne rotor →S pole → yoka.
(2) Stator
Basa re stator nderekugadzira alternating current.
Iyo stator ine stator core uye stator coil.
Nheyo ye stator inoumbwa nemapepa esimbi esilicon ane migero mumhete yemukati, uye dhairekita re stator winding rinoiswa mu groove ye core.
Kutenderedza stator kune zvikamu zvitatu, uye kutenderedza kwezvikamu zvitatu kunoshandisa kubatana kwenyeredzi kana kubatana kwetriangle (simba guru), izvo zvinogona kugadzira mafambiro emagetsi ezvikamu zvitatu.
Kutenderedza kwezvikamu zvitatu kunofanirwa kurohwa zvichienderana nezvimwe zvinodiwa kuitira kuti pave nefrequency yakafanana, amplitude yakaenzana, musiyano wechikamu che120° three-phase electromotive force.
1. Kureba pakati pemativi maviri anoshanda e coil yega yega kunofanirwa kuenzana nenzvimbo inogarwa ne magnetic pole.
2. Kureba pakati pemipendero yekutanga yemakona ari pedyo echikamu chimwe nechimwe chekumonera kunofanira kunge kwakaenzana kana kuwanda kwedaro rinotorwa nematanda maviri emagineti.
3. Mupendero wekutanga we three-phase winding unofanira kupatsanurwa ne 2π+120o electrical Angle (nzvimbo inogarwa ne magnetic poles mbiri i 360o electrical Angle).
MuJF13 series alternator yemumba, mapango maviri emagineti anomiririra nzvimbo yenzvimbo ye6 slots (60o electrical Angle per slot), magnetic pole inomiririra nzvimbo ye3 slots, saka nzvimbo yenzvimbo yemativi maviri anoshanda ecoil yega yega i3 slots, daro riri pakati pemucheto wekutanga wephase winding iri pedyo necoil i6 slots, mucheto wekutanga wethree-phase winding unogona kuparadzaniswa ne2 slots, 8 slots, 3 slots. 14 slots, nezvimwewo.
(3) Muchina wekugadzirisa
Basa remuchina wekugadzirisa magetsi (alternator rectifier) nderekushandura magetsi emagetsi emuchina wekugadzirisa magetsi (three-phase alternating current) emuchina wekugadzirisa magetsi (stator) kuita magetsi akananga (direct current). Muchina wekugadzirisa magetsi wemuchina wekugadzirisa magetsi we6-tube idunhu rekugadzirisa magetsi remabhurogo rine mafungu matatu rine madhiodhi matanhatu esilicon rectifier, uye machubhu matanhatu ekugadzirisa magetsi (6 rectifier tubes) anodzvanywa (kana kuti kusungirirwa) pamaplate maviri.
1. Hunhu hwema diode emota esilicon rectifier
(1) Simba guru remagetsi rinoshanda, simba remagetsi repamberi 50A, simba remagetsi repamusoro 600A;
(2) Voltage yepamusoro yekudzokera shure, voltage yekudzokera shure yekudzokera shure 270V, voltage yekudzokera shure isingadzokorori yekusvika 300V;
(3) Pane lead imwe chete. Uye mamwe ma diode leads akanaka, mamwe ma diode leads haana kunaka, chubhu ine lead line yakanaka inonzi chubhu yakanaka, uye chubhu ine lead line yakaipa inonzi chubhu isina kunaka, saka rectifier diode ine diode yakanaka uye diode isina kunaka.
(4) Chifukidziro chekupedzisira
Chifukidziro chekupedzisira chinowanzo kamurwa kuita zvikamu zviviri (chifukidziro chepamberi nechifukidziro cheshure), izvo zvinoita basa rekugadzirisa rotor, stator, rectifier uye brush assembly. Chifukidziro chekupedzisira chinowanzo gadzirwa nealuminium alloy, iyo inogona kudzivirira kubuda kwemagnetic uye ine simba rakanaka rekupisa.
Chifukidziro chekumashure chine bhurashi rinoumbwa nebhurashi, chibatiso chebhurashi uye chitubu chebhurashi. Basa rebhurashi nderekuisa simba remagetsi kuburikidza neringi yekuunganidza mumhepo inotenderera.
Kubatana kuripo pakati pemagnetic field winding (mabhurashi maviri) nejenareta kwakasiyana, zvekuti jenareta yakakamurwa kuita mhando dzemukati nedzekunze.
1. Jenareta yesimbi yemukati: Jenareta ine bhurashi remagineti rinomonera simbi isina simba rinomonera simbi zvakananga (yakabatana zvakananga nehomwe).
2. Jenareta yakaputirwa nekunze: Jenareta ine mabhurashi ese ari maviri emupendero wemunda anodzivirirwa kubva mugomba.
Electrode isina kunaka (bhurashi isina kunaka) yemagnetic field winding yejenareta yekunze yesimbi yakabatana neregulator, uye simbi yacho yakabatana mushure mekupfuura.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemota zveMG&MAUXS zvinogamuchirwa kutenga.
