1.Iintlobo kunye neempawu ezisebenzayo zejeneretha
Ijenereyitha sisixhobo esivelisa umbane xa siphantsi kwamandla omatshini.Kule nkqubo yokuguqulwa, amandla omatshini avela kwiindidi zezinye iindlela zamandla, njengamandla omoya, amandla amanzi, amandla obushushu, amandla elanga njalo njalo.Ngokweentlobo ezahlukeneyo zombane, iijenereyitha zahlulwe ikakhulu zibe ziijenereyitha zeDC kunye neejenereyitha zeAC.
1. Iimpawu ezisebenzayo ze-DC generator
Ijeneretha yeDC ineempawu zokusetyenziswa ngokulula kunye nokusebenza okuthembekileyo.Inokubonelela ngokuthe ngqo amandla ombane kuzo zonke iintlobo zezixhobo zombane ezifuna umbane weDC.Nangona kunjalo, kukho umhambisi ngaphakathi kwijenereyitha ye-DC, ekulula ukuvelisa i-spark yombane kunye nokusebenza kombane ophantsi.Ijeneretha yeDC ingasetyenziswa ngokubanzi njengonikezelo lwamandla eDC kwimoto ye-DC, i-electrolysis, i-electroplating, ukutshaja kunye nokuvuselela i-alternator.
2. Iimpawu ezisebenzayo ze-alternator
Ijeneretha ye-AC ibhekisa kwijeneretha eyenza i-AC phantsi kwesenzo samandla omatshini angaphandle.Olu hlobo lwejenereyitha lunokwahlulwa lube yi-synchronous AC yokuvelisa amandla
Ijeneretha ye-synchronous yeyona ixhaphakileyo phakathi kweejenereyitha ze-AC.Olu hlobo lwejenereyitha luvuyiswa yi-DC yangoku, enokubonelela ngamandla asebenzayo kunye namandla asebenzayo.Ingasetyenziselwa ukubonelela ngombane kwizixhobo ezahlukeneyo zomthwalo ezifuna umbane we-AC.Ukongeza, ngokweendlela ezahlukeneyo zokushukuma ezisetyenzisiweyo, iijenereyitha ezihambelanayo zinokwahlulwa zibe ziijenereyitha zeinjini yomphunga, iijenereyitha zehydro, iijenereyitha zedizili kunye neeinjini zomoya.
Ii-alternators zisetyenziswa ngokubanzi, umzekelo, iijenereyitha zisetyenziselwa ukubonelela umbane kwizikhululo zamandla ezahlukeneyo, amashishini, iivenkile, unikezelo lwamandla ombane asekhaya, iimoto, njl.
Iiparamitha zemodeli kunye nezobugcisa zejeneretha
Ukuququzelela ulawulo lwemveliso kunye nokusetyenziswa kwejenereyitha, urhulumente uye wadibanisa indlela yokudibanisa imodeli yejenereyitha, kwaye wancamathisela i-nameplate yejeneretha kwindawo ecacileyo yeqokobhe layo, elibandakanya ikakhulu imodeli yejenereyitha, amandla ombane alinganisiweyo, amandla alinganisiweyo. unikezelo, amandla alinganisiweyo, ibakala lokugquma, amaza, amandla kunye nesantya.
Imodeli kunye nentsingiselo yejenereyitha
Imodeli yejeneretha idla ngokuba yinkcazo yomzekelo weyunithi, kubandakanywa nohlobo lwemveliso yombane ngujeneretha, uhlobo lweyunithi yejeneretha, iimpawu zokulawula, inombolo yoyilo kunye neempawu zokusingqongileyo.
Ukongezelela, iimodeli zezinye iijeneretha zinembile kwaye zilula, ezilungele ngakumbi ukuchonga, njengoko kuboniswe kuMzobo 6, kubandakanywa nenombolo yemveliso, i-voltage elinganisiweyo kunye nexabiso langoku.
(1) Umbane olinganisiweyo
I-voltage elinganisiweyo ibhekiselele kwisiphumo sombane olinganisiweyo yijenereyitha ngexesha lokusebenza okuqhelekileyo, kwaye iyunithi yi-kV.
(2) Ilinganiswe ngoku
Ireyithingi yangoku ibhekiselele kubuninzi bomsebenzi wangoku wejeneretha phantsi kwesiqhelo kunye nokusebenza okuqhubekayo, kwiKa.Xa ezinye iiparameters zejeneretha zilinganiswe, i-generator isebenza ngeli xesha, kwaye ukunyuka kweqondo lokushisa kwe-stator winding yayo akuyi kudlula uluhlu oluvumelekileyo.
(3) Isantya sokujikeleza
Isantya sejeneretha sibhekisela kwisantya esiphezulu sokujikeleza kwe-shaft ephambili ye-generator ngaphakathi kwe-1min.Le parameter yenye yeeparamitha ezibalulekileyo zokugweba ukusebenza kwejeneretha.
(4) Ukuphindaphinda
Ukuphindaphinda kubhekisa kuphindaphindana kwexesha le-AC sine wave kwijenereyitha, kwaye iyunithi yayo yiHertz (Hz).Ngokomzekelo, ukuba i-frequency ye-generator yi-50Hz, ibonisa ukuba isalathiso sokutshintshana kwayo ngoku kunye nezinye iiparamitha ze-1 zitshintsha amaxesha angama-50.
(5) Umba wamandla
Ijenereyitha ivelisa umbane ngokuguqulwa kwe-electromagnetic, kwaye amandla ayo aphumayo anokwahlulwa abe ziintlobo ezimbini: amandla asebenzayo kunye namandla asebenzayo.Amandla asebenzayo asetyenziswa ikakhulu ukuvelisa imagnethi kunye nokuguqula umbane kunye nemagnethi;Amandla asebenzayo anikezelwa kubasebenzisi.Kwisiphumo esipheleleyo samandla ejenereyitha, umlinganiselo wamandla asebenzayo ngumba wamandla.
(6) Uqhagamshelwano lweStator
Uqhagamshelo lwe-stator lwejeneretha lunokwahlulwa lube ziindidi ezimbini, ezizezi zinxantathu (△ uxhulumaniso olubunjiweyo) kunye nenkwenkwezi (i-Y-shaped), njengoko kubonisiwe kuMfanekiso 9. inkwenkwezi.
(7) Iklasi ye-Insulation
Umgangatho wokugquma wejenereyitha ikakhulu ubhekisa kwinqanaba lokumelana nobushushu obuphezulu bezinto zayo zokugquma.Kwi-generator, i-insulating material iyikhonkco ebuthathaka.Izinto eziphathekayo zilula ukukhawulezisa ukuguga kunye nomonakalo kwiqondo lokushisa eliphezulu kakhulu, ngoko ke ibakala lokumelana nobushushu bezinto ezahlukeneyo zokugquma likwahlukile.Le parameter idla ngokumelwa ngoonobumba, apho uy ebonisa ukuba iqondo lobushushu elikwaziyo ukumelana nobushushu yi-90 ℃, a libonisa ukuba iqondo lobushushu elimelana nobushushu yi-105 ℃, e libonisa ukuba iqondo lobushushu elikwaziyo ukumelana nobushushu yi-120 ℃, B ibonisa ukuba ubushushu -iqondo lobushushu elikwaziyo ukumelana nobushushu yi-130 ℃, f ibonisa ukuba iqondo lobushushu elikwaziyo ukumelana nobushushu yi-155 ℃, H libonisa ukuba ubushushu obuxhathisayo yi-180 ℃, kwaye i-C ibonisa ukuba iqondo lobushushu lingaphezulu kwe-180 ℃.
(8) Okunye
Kwi-generator, ngaphezu kweeparitha zezobugcisa ezingentla, kukho kwakhona iiparitha ezifana nenani lezigaba ze-generator, ubunzima obupheleleyo beyunithi kunye nomhla wokuvelisa.Ezi parameters zinengqondo kwaye kulula ukuyiqonda xa ufunda, kwaye ikakhulu kubasebenzisi ekubhekiselwa kuzo xa besebenzisa okanye bethenga.
3, Uphawu lokuchongwa kwejenereyitha emgceni
Ijenereyitha yenye yezinto ezibalulekileyo kwiisekethe zolawulo ezifana nokuqhuba umbane kunye nesixhobo somatshini.Xa udweba umzobo weskimu ohambelana nesiphaluka ngasinye solawulo, i-generator ayibonakali ngobume bayo boqobo, kodwa imakwe ngemizobo okanye imizobo, iileta kunye nezinye iimpawu ezimele umsebenzi wayo.
