Corona tso tawm tshwm sim thaum lub teb hluav taws xob tsis sib xws yog tsim los ntawm tus neeg coj tsis du. Nyob ib puag ncig lub teb hluav taws xob tsis sib xws thiab ze ntawm lub electrode nrog lub vojvoog me me ntawm curvature, thaum lub zog nce mus rau qee qib, vim yog ionization ntawm huab cua, kev tso tawm yuav tshwm sim, tsim lub corona.
Los ntawm cov xwm txheej rau kev tsim corona, peb tuaj yeem pom tias cov teb hluav taws xob tsis sib xws, cov neeg hlau tsis du, thiab cov hluav taws xob siab txaus yog cov xwm txheej tsim nyog rau kev tsim corona. Yog li ntawd, corona yuav tshwm sim ntawm qhov kawg ntawm cov windings ntawm cov motors siab voltage, tshwj xeeb tshaj yog rau cov motors nrog lub zog ntsuas siab dua 6kV, corona ntawm stator windings yuav pom tseeb dua, thiab qhov siab dua qhov hluav taws xob, qhov teeb meem corona yuav loj dua. Yog li ntawd, rau cov windings ntawm cov motors siab voltage, cov kev ntsuas kho tiv thaiv corona raug coj los ntawm kev siv cov xov hlau electromagnetic tshwj xeeb thiab cov ntaub qhwv tiv thaiv rau sab nraud ntawm cov kauj winding. Hais txog qhov teeb meem corona ntawm cov motors siab voltage, tib neeg txoj kev nkag siab yog qhov tseem ceeb. Tom qab ntawd, vim li cas corona kuj tshwm sim hauv cov motors hloov pauv zaus?
Cov cav hloov pauv zaus yog siv los ntawm cov tsav hloov pauv zaus. Lub zog hluav taws xob tso tawm los ntawm cov tsav hloov pauv zaus tsis yog nthwv dej sine zoo li ntawm lub zog muab hluav taws xob ntawm qhov zaus kev lag luam, tab sis nthwv dej plaub fab nrog kev nce thiab nqis siab. Lub nthwv dej pulse tshwj xeeb no ua rau lub zog nkag ntawm lub cev muaj zog muaj qhov siab tshaj plaws uas yog ob npaug ntawm qhov hluav taws xob ntsuas. Vim yog qhov ceev ceev ntawm qhov kev hloov pauv pulse no, nws yuav ua rau muaj kev tsis sib xws loj hauv kev faib hluav taws xob ntawm cov windings ntawm lub cev muaj zog. Txawm hais tias feem ntau cov cav hloov pauv zaus yog cov cav qis-voltage, txoj kev muab hluav taws xob tshwj xeeb txiav txim siab qhov tsis sib xws ntawm lub zog hluav taws xob hauv lawv cov windings.
Raws li cov yam ntxwv ntawm tus lej ntawm cov windings thiab qhov ntev ntawm txhua qhov winding hauv lub cev muaj zog, thawj thiab kawg windings ntawm qhov qis-voltage siab-power motor winding dais yuav luag tag nrho cov voltage amplitude, thiab lawv kuj yog cov feem ntau yooj yim rau teeb meem hauv lub cev muaj zog winding. Ntxiv mus, los ntawm kev tshuaj xyuas ntawm cov txheej txheem embedding winding, thawj winding coil raug kev puas tsuaj ntau dua, thiab yog li nws ntsib kev phom sij ntau dua. Qhov no yog vim li cas ntau lub tuam txhab tsim lub cev muaj zog muab kev tiv thaiv tshwj xeeb rau thawj thiab kawg windings. Rau cov qis-voltage siab-power variable zaus motors, vim yog lub zog tsis sib xws thiab lub zog siab tshaj plaws ntawm lub pulse, qhov kawg ntawm lub cev muaj zog winding muaj cov xwm txheej yooj yim rau kev tsim corona. Txhawm rau tiv thaiv kev tsim corona hauv lub cev muaj zog hloov pauv zaus, qhov winding ntawm lub cev muaj zog hloov pauv zaus yuav tsum tau txais cov hlau hluav taws xob tshwj xeeb tiv thaiv corona, thiab cov kev ntsuas tiv thaiv tshwj xeeb yuav tsum tau ua rau thawj thiab kawg windings.
