Umgaqo wolawulo oluzenzekelayo lweejenereyitha zeemoto
Umgaqo wokulawula ngokuzenzekelayo weejenereyitha zeemoto ikakhulu ufezekisa uzinzo lwevolthi ngokungenisa i-electromagnetic kunye nolawulo lwangoku lwentsimi yemagnethi. Le yindlela ethile ilandelayo:
Indlela yokulawula ukungeniswa kwe-electromagnetic
Ijenereyitha ilungisa ngokuzenzekelayo ukuveliswa kombane wayo ngokwemfuno yombane. Xa amandla ebhetri enganele okanye kusetyenziswa izixhobo zombane ezinamandla aphezulu, ijenereyitha yonyusa ukuveliswa kombane ngokuphucula umbane we-magnetic field. Xa ibhetri itshajwe ngokupheleleyo, umbane we-magnetic field uyancitshiswa ngokuzenzekelayo, kodwa igcina kuphela umbane osisiseko.
Umgaqo wolawulo lwe-voltage
I-magnetic flux itshintshwa ngokulungelelanisa ngokuzenzekelayo i-magnetic field current ukuqinisekisa uzinzo lwe-output voltage. Xa isantya sokujikeleza sejenereyitha sitshintsha, okubangela ukuguquguquka kwe-voltage, umlawuli ufumanisa isignali engaqhelekanga aze alungise amandla e-magnetic field ngokutshintsha i-excitation current, ngaloo ndlela ebuyisela i-voltage kuluhlu olubekiweyo. Umzekelo, xa isantya sokujikeleza sisanda, nciphisa i-excitation current ukuthintela i-overvoltage; xa isantya sokujikeleza sincipha, yongeza i-excitation current ukuze ugcine uzinzo lwe-voltage.
Iindidi ezahlukeneyo zabalawuli
Umlawuli wereyila we-Youdaoplaceholder0 : Ngokulawula ukuvulwa kweekhonkco zereyila ukulawula isekethe yentsimi yemagnethi, ulawulo lwe-voltage oluzenzekelayo luyafezekiswa.
I-Youdaoplaceholder0 Abalawuli be-elektroniki (njengohlobo lwe-grounding yangaphakathi/uhlobo lwe-grounding yangaphandle): Basebenzisa izinto ezifana nee-transistors kunye nee-voltage stabilizing diodes ukulawula i-magnetic field current ngokusebenzisa i-circuit on-off.
Le nkqubo inokulinganisela ngokufanelekileyo ukuveliswa kombane kunye nemfuno yombane, ithintele inkcitho yamandla kwaye yandise ubomi benkonzo yezixhobo.
Ijenereyitha yemoto yeyona mthombo wamandla oyintloko wesithuthi. Umsebenzi wayo kukubonelela ngombane kuzo zonke izixhobo zombane (ngaphandle kwesiqalo) ngelixa injini isebenza ngendlela eqhelekileyo, kwaye kwangaxeshanye itshaje ibhetri.
Ngokusekelwe kwi-stator winding yamanqanaba amathathu ye-alternator eqhelekileyo, inani lokujika kwe-winding liyandiswa kwaye ii-terminals zonxibelelwano ziyakhokelwa ngaphandle, kwaye kongezwa iseti ye-rectifier ye-bridge yamanqanaba amathathu. Ngesantya esiphantsi, i-winding yokuqala kunye ne-winding eyongezelelweyo zikhutshwa ngokulandelelana, ngelixa ngesantya esiphezulu, yi-winding yokuqala yamanqanaba amathathu kuphela ekhutshwayo.
Umgaqo wokusebenza we-alternator iyonke
Xa isekethe yangaphandle inika amandla ukujijeka kwe-excitation ngebrashi, kuvela intsimi yemagnethi, i-magnethize iipali ze-claw kwiipali ze-N kunye neepali ze-S. Xa i-rotor ijikeleza, i-magnetic flux iyatshintshatshintsha kwi-stator windings. Ngokomgaqo we-electromagnetic induction, amandla e-electromotive atshintshiweyo adalwa kwi-three-phase windings ye-stator. Lo ngumgaqo wokuvelisa umbane we-alternator.
Irotha yejenereyitha ye-DC excited synchronous iqhutywa yi-prime mover (oko kukuthi, injini) ukuze ijikeleze ngesantya se-n(rpm), kwaye i-stator winding yamanqanaba amathathu ibangela amandla okutshintshana kwamandla. Ukuba i-stator winding iqhagamshelwe kumthwalo wombane, i-motor iya kukhupha i-alternating current. I-alternating current iguqulwa ibe yi-direct current nge-rectifier bridge ngaphakathi kwijenereyitha ize iphume kwi-output terminal.
I-alternator yahlulwe yangamacandelo amabini: i-stator winding kunye ne-rotor winding. Ii-stator windings zesigaba esithathu zisasazwa kwi-casing kwi-engile yombane ye-120 degrees enye kwenye, kwaye i-rotor winding yenziwe ngee-pole claws ezimbini. Xa i-rotor winding iqhagamshelwe kwi-direct current, iyavuselelwa, kwaye ii-poles ezimbini zenza i-N pole kunye ne-S pole. Imigca ye-magnetic field iqala kwi-N pole, idlule kwi-air gap iye kwi-stator core ize ibuyele kwi-S pole esecaleni. Nje ukuba i-rotor ijikeleze, i-rotor winding iya kunqumla imigca ye-magnetic field, ivelise amandla e-sinusoidal electromotive kwi-stator winding ahluke ngama-degrees e-120 e-electric degree, oko kukuthi, i-three-phase alternating current, eguqulwa ibe yi-direct current output yi-rectifier element eyenziwe ngama-diodes.
Xa iswitshi ivaliwe, umbane uqala unikwe yibhetri. Isekethe yile:
Isiphelo sebhetri esilungileyo → isibane sokutshaja → uqhagamshelwano lomlawuli → ukujija komoya → ukumisa ibhetri phantsi → isiphelo esingalunganga sebhetri. Kule ndawo, isibane sokutshaja siya kukhanya kuba kukho umbane odlula kuso.
Nangona kunjalo, emva kokuba injini iqalile, njengoko isantya sokujikeleza sejenereyitha sisanda, i-voltage yesiphelo sejenereyitha nayo iyaqhubeka nokunyuka. Xa i-voltage yokuphuma yejenereyitha ilingana neyebhetri, amandla kwi-terminals "B" kunye ne "D" yejenereyitha ayafana. Ngeli xesha, isibane sesalathisi sokutshaja siyacima ngenxa yomahluko we-potential phakathi kweziphelo zimbini. Oku kubonisa ukuba ijenereyitha isebenza ngokuqhelekileyo kwaye umsinga wokukhupha unikezelwa yijenereyitha ngokwayo. Amandla e-electromotive alternating current alternating current amathathu aveliswa yi-three-phase winding kwijenereyitha alungiswa yi-diode aze emva koko akhuphe umsinga othe ngqo ukubonelela ngamandla kumthwalo kwaye atshaje ibhetri.
