High-voltage motor ceev tswj tswj cov txheej txheem kev tsim kho tshuab
High thiab tsawg zaus converter
Tus inverter yog low-voltage inverter. Lub sab xa khoom siv ib lub tshuab ua pauv hloov qhov siab qhov siab mus rau qhov tsawg tsawg. Lub siab-voltage lub cev yog hloov. Ib qho tshwj xeeb qis-qis zog siv. Qhov theem ntawm lub tshuab hluav taws xob muaj ntau yam thiab tsis muaj cov qauv zoo.
Txoj kev no siv cov qis-qis qis qis, lub peev xwm tseem yau, thiab kev sib haum ntawm qhov sib pab sab nraud yog loj. 12-lub plhaw ntswj yuav siv tau los txo cov kev sib raug zoo, tab sis cov kev cai nruj heev rau kev sib haum xeeb tsis tuaj yeem ua tau. Thaum muaj teeb meem nyob hauv qhov inverter, lub cav tsis tuaj yeem raug muab tso rau hauv lub hwjchim thooj ntawv, thiab tej zaum yuav muaj teebmeem nyob rau qee cov kev siv uas lub cav tsis tuaj yeem tsum. Tsis tas li ntawd, lub cav thiab lub nplaum yuav tsum tau hloov, thiab qhov nyiaj ua haujlwm yog ib qho loj.
Cascade ceev converter
Rotor lub zog ntawm lub cav asynchronous yog pub rov qab rau lub hwjchim daim phiaj hloov rotor plam mus cuag kev cai tswj ceev. Kev tswj cov cuab yeej no siv cov tshuab thyristor thiab yuav tsum tau siv cov xov tooj cua asynchronous, thiab tam sim no yuav luag txhua lub taubhau as-khaus asynchronous yog siv hauv cov chaw. Nws yog teeb meem heev los hloov lub cav. Tsav kev cai tswj ceev ntawm cov kev cai tswj qhov ceev no feem ntau nyob ntawm 70% -95%, thiab cov cai tswj ceev yog nqaim. Cov tshuab thyristor yog ib qho yooj yim ua rau muaj kev phom sij rau lub hwj chim kab sib chaws; raws li qhov kev txo qis dua, cov phiaj sab nraud kuj ua rau qis, thiab ntsuas yuav tsum tau coj los ua kom them rov qab. Qhov kom zoo dua yog tias qhov kev hloov qhov tsawg tshaj plaws muaj peev xwm tsawg, uas yog qis me dua lwm cov high-voltage AC kuj tsis paub meej txog kev tswj ceev ceev ceev.
Muaj qhov sib txawv ntawm kev tswj cov cai ceev, uas yog, cov tswv yim khiav ceev tswj qhov system, uas tshem tawm cov teeb tsa ntawm qhov kev siv qhov inverter, thiab qhov tawm tswv yim yog ncaj qha rau hauv stator winding. Hom no yuav tsum tau hloov lub cav, thiab lwm yam ntawm kev ua tau zoo thiab kev hloov kho tshiab Qhov kev khiav ceev yog nyob ze.
Txoj kev ceev ceev tswj kev tsav tsheb yog cuam tshuam los ntawm rotor nplhaib ntiv nplhaib, tsis tuaj yeem ua kom tau ntau lub hwj chim, thiab lub nplhaib nplhaib tu lub zog workload kuj yog loj. Nws yog qhov kev siv tshuab rov qab rau xyoo 1970 thiab 1980, thiab daim ntawv thov ua haujlwm tau tsawg dua.
Tam sim no qhov chaw coj ncaj qha high voltage inverter
Nyob rau hauv no hom kev hloov zaus, cov tswv yim sab yog raug kho los ntawm thyristor, lub zog cia ntawm inductor siv, thiab lub SGCT siv los ua cov khoom sib txuas ntawm lub inverter sab, uas yog cov qauv siv ob theem. Txij li thaum lub ntaus ntawv ntawm qhov ntsuas cua tsis muaj zog, ntau yam khoom siv yuav tsum tau txuas nrog rau hauv. Ntaus ntawv series yog ib txoj hauv kev siv technology engineering heev. Nyob rau hauv kev tshawb xav, kev ntseeg tau qis heev, tab sis qee cov tuam txhab tuaj yeem ua tiav cov khoom lag luam. Vim cov qhov tso zis muaj tsuas muaj ob theem thiab lub cav raug rau ib qho loj dv / dt, yuav tsum siv cov lim tawm. Multi-pulse rectifiers rau ntawm daim phiaj sab nraud yog xaiv tau thiab cov neeg siv yuav tsum tau thov rau lawv tus kheej cov nroj tsuag puag. Qhov loj ntawm qhov sib txawv ntawm cov khoom sib txuas yog qhov ua rau lub zog ntawm lub voj voos tuaj yeem siv rov qab mus rau ntawm kab sib chaws tsis tas yuav tsum tau ua rau sab nraud.
Qhov kev tsis zoo ntawm cov hom kev lag luam tam sim no yog qhov sib npaug ntawm qhov sib txawv ntawm daim phiaj sab nraud, qhov sib haum xeeb loj loj, thiab nws hloov nrog kev hloov ntawm kev ua haujlwm, uas tsis yooj yim rau kev nplua.
