Iikhrayitheriya zoYilo lwe-Perkins ye-EMC

Iikhrayitheriya zoyilo oluhambelana ne-Electromagnetic ye-Perkins generator yokusetyenziswa kwiziko ledatha.

(1) Sebenzisa ngokupheleleyo kwaye udlale ngokupheleleyo ukuhambelana kombane wezixhobo zombane ezisetyenzisiweyo.Kubandakanya: ① ​​ukukhetha izixhobo zombane ezinokunyamezela umqondiso omkhulu;② Khetha izixhobo zombane ezinesantya esifanelekileyo;③ Nciphisa uthintelo lwegalelo lwesekethe yegalelo (ingakumbi isekethe yegalelo elikude) kangangoko kunokwenzeka;④ Nciphisa imveliso ngokufanelekileyo.

(2) Uyilo lwenkqubo yokubonelela ngombane Perkins generator diesel .Kubandakanya: ① ​​khetha imodyuli yamandla enesakhono sokudibanisa esincinci kwicala eliphambili nakwicala lesibini kunye nesakhono esikhulu sokudibanisa emhlabeni kwicala eliphambili;② Yamkela isiseko esisasaziweyo samandla kangangoko kunokwenzeka;③ Uluhlu olusebenzayo lombane we-AC wemodyuli yamandla kufuneka ibe nkulu ngokwaneleyo.

(3) Ukukhethwa kwendlela yokumisa.① Ngokubanzi, isiseko esithe ngqo samkelwa;② Xa inxalenye yokulawula idibaniswe ngombane kunye nezixhobo eziphezulu ze-voltage, imodi yomhlaba odadayo yamkelwa;③ Umthamo osasaziweyo wenkqubo yomhlaba edadayo kufuneka ilawulwe ngokungqongqo.

(4) Ukulungiswa komthamo osasaziweyo wenkqubo yolawulo.① Zama ukunciphisa amandla okudibanisa phakathi kwamacala aphambili kunye nesibini ukuvala umendo wokuphazamiseka kwendlela eqhelekileyo;② Iringi yemagnethi yemowudi eqhelekileyo ifakwe kwindawo yokufaka izibuko, kwaye emva koko i-symmetrical high-frequency capacitance ukuya emhlabeni idityanisiwe;③ Gcina ucingo lokumisa kude kwezinye iingcingo zomqondiso;④ Ukunciphisa amandla okusasazwa kwenkqubo;⑤ Vavanya umthamo osasaziweyo wenxalenye nganye emhlabeni, uhlalutye ukuhamba kokuhanjiswa kokuphazamiseka kwemodi eqhelekileyo, uqikelele impembelelo yokuphazamiseka kwemowudi eqhelekileyo, kwaye wenze amanyathelo obugcisa okuthintela ukuphazamiseka.

Ziziphi izibonakaliso eziphambili zezobugcisa zomqondiso omkhulu kunye neempawu zesignali ezincinci?

Izalathisi eziphambili zobuchwephesha benkqubo yovuselelo ziquka:

(1) Izalathisi eziphambili zobuchwephesha zeempawu ezinkulu zomqondiso: ① kwinkqubo yovuselelo yesiqhelo, izalathisi zobuchwephesha ziphezulu ombane obuninzi kunye nomlinganiselo wokuphendula umbane wovuselelo;② Kwinkqubo ye-excitation enempendulo ephezulu yokuqala, izalathisi zobugcisa ziphezulu zombane obuninzi kunye nexesha lokuphendula lombane we-excitation.

(2) Izalathisi eziphambili zobuchwephesha beempawu zeempawu ezincinci zezi: ixesha lokunyuka, ixesha lokulungelelanisa, ixesha lokudlula kunye ne-oscillation.Izalathi ezisemgangathweni zezi: ukugqithisa ≤ 50%, ixesha lokulungelelanisa ≤ IOS, amaxesha oscillation ≤ 3 amaxesha.

Kutheni ukulinganisa i-rotor-speed-up insulation xa i-generator iqalisiwe?Kwezinye ii-rotor ze-generator, i-grounding fault of generator rotor winding ihlala ihambelana namandla e-centrifugal xa i-rotor ijikeleza, kodwa olu hlobo lwephutha alukwazi ukubonakaliswa kuvavanyo phantsi kokuvalwa.Ngoko ke, xa i-generator iphakama ukusuka kwisantya se-zero ukuya kwisantya esilinganisiweyo, ukulinganisa ukugquma kwe-rotor winding kweli nqanaba kunokugweba ukuba kukho impazamo enjalo kwi-rotor winding, ukuze ufumane ngokuchanekileyo impazamo kwaye uqinisekise ukuba akukho ngozi efihliweyo. ukusebenza okuqhelekileyo kwe-rotor winding.

Isilawuli sokuvuselela iSemiconductor

Kwinkqubo ye-excitation ye-semiconductor, iyunithi yamandla e-excitation yi-semiconductor rectifier kunye nonikezelo lwamandla ombane we-AC, kwaye umlawuli wokuvuselela uqulunqwe ngamacandelo e-semiconductor, amacandelo aqinileyo kunye neesekethe ze-elektroniki.Umlawuli wangaphambili ubonise kuphela ukutenxa kombane wejeneretha kwaye wenza ulungiso lombane.Idla ngokuba yi-voltage regulator (i-voltage regulator ngokufutshane).Umlawuli wangoku unokubonakalisa ngokubanzi uluhlu lweempawu zolawulo ezibandakanya isignali yokutenxa kwamandla ombane kulawulo lwe-excitation, ngoko kubizwa ngokuba yi-excitation regulator.Ngokucacileyo, i-excitation regulator ibandakanya umsebenzi we-voltage regulator.
