Aaladaha Korontada ee Kuleyliyaha Dhalinta

Kuleyliyaha induction waxaa inta badan loo isticmaalaa dhalaalinta birta, ilaalinta kulaylka, jeexista, alxanka, deminta, dabciga, diathermy, nadiifinta birta dareeraha ah, daawaynta kulaylka, foorarsiga tuubooyinka, iyo koritaanka crystal.Qalabka korontadu wuxuu ka kooban yahay wareegtada hagaajinta, wareegga wareegga, wareegga culeyska, xakamaynta iyo wareegga ilaalinta.

Farsamaynta tamarta soo noqnoqda ee dhexdhexaadka ah ee kuleyliyaha induction waa tignoolajiyada dib u habeynta soo noqnoqoshada tamarta hadda jirta (50Hz) si ay u toosiso awoodda ka dibna u beddesha soo noqnoqoshada dhexdhexaadka ah (400Hz ~ 200kHz) iyada oo loo marayo aaladaha semiconductor-ka sida thyristor, MOSFET ama IGBT.Tiknoolajiyadu waxay ku jirtaa hababka xakamaynta dabacsan, awoodda wax soo saarka ee weyn, iyo waxtarka ka sarreeya cutubka, oo ku habboon in la beddelo inta jeer ee waafaqsan shuruudaha kuleylka.

Dib-u-habeeyaha qalabka korontada yar iyo kan dhexe wuxuu qaataa hagaajinta thyristor saddex-waji ah.Qalabka korantada ee awoodda sare leh, hagaajinta 12-pulse thyristor ayaa lagu dabaqi doonaa si loo hagaajiyo heerka korantada ee sahayda iyo in la yareeyo xadhkaha-dhinaca harmonic hadda.Unugga korantada inverter-ku wuxuu ka kooban yahay koronto-sare-sare oo degdeg ah thyristor isbar-bar socda oo ku xiran si loo xaqiijiyo soo-saarka awoodda sare.

Inverter iyo wareegga resonant waxaa loo qaybin karaa laba nooc iyadoo loo eegayo sifooyinka qaab-dhismeed: 1) nooca resonant barbar, 2) nooca resonant taxane.

Nooca resonant barbar socda:-sare-sare-hadda biyaha qaboojiyey thyristor (SCR) ayaa loo isticmaalaa in lagu sameeyo unugga inverter nooca hadda, iyo wax soo saarka koronto sare waxaa lagu xaqiiqsaday by superposition of thyristors.Wareegga resonant wuxuu guud ahaan isticmaalaa qaab-dhismeed isbarbar socda oo dhammaystiran, sidoo kale dooro laba-voltage ama qaab beddelka si loo kordhiyo tamarta inductor iyadoo loo eegayo shuruudo kala duwan, oo inta badan lagu dabaqo habka daaweynta kuleylka.

Nooca resonant Taxanaha ah: Tayristor-biyo-qaboojiye-sare-sare (SCR) iyo diode degdeg ah ayaa loo adeegsadaa si loo sameeyo unugga korantada ee nooca korantada ah, wax-soo-saarka awoodda sare waxaa lagu gartaa superposition of thyristors.Wareegga dhawaaqa wuxuu isticmaalaa qaab-dhismeed dhawaaqeed taxane ah, iyo transformer-ka ayaa loo qaatay si uu u dhigmo shuruudaha culeyska.Marka lagu daro faa'iidooyinka awoodda sare ee dhinaca Grid-side, kala duwanaanta hagaajinta korantada, hufnaanta kuleylka sare iyo heerka guusha bilowga sare, waxay noqotay mid aad iyo aad loo isticmaalo sanadaha hadda oo inta badan lagu dabaqo habka dhalaalidda.

Ka dib wanaajinta habka wax-soo-saarka, Runau waxay soo saartaa beddelka degdegga ah ee thyristor waxay isticmaashaa shucaaca neutronka iyo habab kale si ay u soo gaabinayso wakhtiga daminta iyo awoodda korontadu waa la wanaajiyey.

Korontada kuleyliyaha soo noqnoqda ee dhexdhexaadka ah waxay qabataa thyristor maadaama aaladda korantada ee ugu weyni ay dabooshay dhammaan beeraha inta jeer ee ka hooseeya 8kHz.Awoodda wax soo saarka ayaa loo qaybiyaa 50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW inta jeer ee hawlgalka waa 200Hz, 400Hz, 1kHz, 2.5kHz, 8kHz10 tan, 12 tan, 20 tan oo birta dhalaalaysa iyo kaydinta kulaylka, qalabka korontada ugu muhiimsan waa sahay koronto dhexdhexaad ah.Hadda awoodda wax-soo-saarka ugu badan waxay timaaddaa 20000KW oo 40Tan ah.Thyristor-ku waa beddelka awoodda muhiimka ah & qaybta roganta ee lagu dabaqayo.
